Get Your Diseased & Gnarly Tomatoes OUT!

/0 Comments/in , , , , , , , /by

It’s August and hot, not the most fun time in the garden, but you’ve got to go out and EVICT all the diseased and dying stuff out of your garden.  You’re not doing for this year’s produce…you’re doing to save your garden next year.

In Colorado with our warm winter and early hot Spring, we are inundated with pest problems.  Most on our minds today is the spotted wilt virus on tomatoes which makes pretty concentric circles on the tomatoes, but leaves the fruit tasteless and mealy…and kills the plant long before frost.  As depressing as it is to toss plants you’ve nurtured since they were just baby seeds, they’ve got to go. They aren’t going to get better and the virus will just get spread around your garden.

So get out there with your wheelbarrow and do some decluttering.

Tomato plants with spotted wilt virus or mosaic virus or even some nasty blight:  OUT! And not into your compost pile…they go right in the garbage.

Other plants with serious disease problems:  OUT!  You’re never going to eat those gone to flower broccoli covered with powdery mildew.

Weeds that have grown four feet tall when you weren’t looking are now going to seed.  Somehow huge prickly lettuce and thistles keep appearing out of nowhere with big seed heads.  OUT!

It won’t take long to clean up the big stuff….this is one of those 15-minute projects.  15 minutes now will make a huge difference later. 15 minutes now gives the good healthy tomatoes more light and space and water to make lots of fruit before frost.  15 minutes now means you pull all the diseased fruit and leaves out easily now instead of trying to retrieve dead rotting fruit and diseased leaves after frost has caused leaf drop.

And while you’re at it:  those big huge zucchini bats:  OUT.  Pull ’em off the plant so that nice tender young zucchinis can grow.  You’re just not likely to eat as much giant zucchini as you’re growing.  Let go of the guilt and send them to enrich the compost.

 

Ignoring what “they” say.

I visited a garden yesterday tended by my friend Lou.  Lou has gardened for other people for many years and the heavy shade garden I visited has lots of color despite being in shade and the fact that we’ve been in high temperature, drought conditions.

As we walked around and she told me some of the secrets of the garden’s success, I found myself thinking, “But “they” say not to do that.”  Things like “they” say native plants don’t want rich soil and shouldn’t be fertilized like other garden plants.  Hah. Her well-fed natives were twice the size of mine.  Or “they” say dahlias don’t do well in shade and need full sun.  She had twenty magnificent blooming dahlias that begged to differ.  And she used all kinds of plants the opposite of what the labels say:  Euonymous species, sold as shrubs, were tough interesting reliable groundcovers when kept short by pruning.

My favorite gardeners have always been the ones who don’t do what “they” say without thinking about what might actually work.  My first experience was an older gentleman who had grown tomatoes for 70 years by the time I met him.  He had tried all the tomato techniques I ever heard of.  “Epsom salts,” he guffawed…”don’t do a thing except make the tomatoes taste salty.”  “Water has to be consistent.”  He had watered every day with soaker hoses since they had been invented.  So as I watched him fertilize, I expected some down-home advice.  Instead, I watched in horror as he just spooned tablespoons of dry Miracle Grow crystals right next to the tomato stem.  “But, but…” I stammered, “Aren’t you going to burn the plants and kill them?”  Nope….they just got watered in slow-release-like with each soaker hose watering and he had the best tomatoes in town.

That still didn’t match the shock of watching my friend Barbara.  She definitely walks her own path and is agreed by all to be the best gardener we know.  She never fertilized with fertilizers. She composts and mulches and puts goat manure and earthworm compost on everything, but she has never bought a bottle of something and put it on her yard. Geraniums bloomed in containers for fifteen years with only compost and maybe grass clippings in the bottom of the pot for the earthworms to eat. The most startling part of watching her garden was that she never treated pests.  Sawflies came two years in a row and ate every single leaf on her six-foot-tall gooseberries. They looked terrible.  She made sure the plants were watered and had lots of compost, but said the plants needed to figure it out if they wanted to survive. It was up to them to figure out how to defend themselves.  She just made sure the garden environment was good.  To my amazement, the plants survived and put out new leaves, and the third year the beetles didn’t return.  Who knew?

I still do lots of things “they” say because much is based on someone’s research and experience.  But I keep an open mind. Every time somebody gives me a lecture about the right way to garden or what “they” say I should be doing, I ask myself, “Who is this ‘they’?” “And who gave them all the power?”

 

 

Seeds in the Garden

Now that we’re at the peak of summer, you’ll start to notice that your garden is likely to have more seeds than it has flowers.  The heat and long days of summer have stimulated seed formation in most plants and this is a good thing.  Don’t just deadhead the seeds and compost them… there are lots you can do with flowers gone to seed.

Collect the seeds to grow again.

Once seedheads have dried a bit (turned brown) and the seeds are loose, you can collect the seed…either to save in paper envelopes for next year or to spread around the garden now where you’d like them to grow next.  When collecting seeds to grow next year, pick the healthiest plants with the best color. You probably know that some plants are hybrid and don’t necessarily come true from seed…but sometimes they do, so I like to risk it.  This year we let a squash grow in the compost pile even though everybody knows squash don’t come true, but it was cute…and now we’ve been eating great acorn squash a month earlier than the garden’s because the plant didn’t know it wasn’t supposed to be good.

Eat the seeds.

This is especially yummy before the seeds mature when they are still green and tender.  Green herb seeds and cool season vegetable seeds are little flavor powerhouses.  It’s time to nibble on broccoli flowers or herb seeds – cilantro, dill, fennel, anise, even basil.  All the flax in my wildflower patch has gone to seed.  I’m gathering them to sprout and either put on salads or dehydrate into crackers.

Gather the dry seeds for birdseed in winter

Sunflower and flax seeds are some of the seeds that birds like, so I gather extra dry seed to put out in January for the chickadees. I leave most of the seed on the ground for them… but sometimes it’s hard for a tiny bird to find seeds through a foot of snow.  Besides, if I put the seeds in the bird feeder, I (and the cats) get the pleasure of watching through the kitchen window.

Let the seeds be.

You can grow perennial beds of annuals.  There’s a phrase to get your head around.  The plants don’t overwinter but by letting the seeds drop, they replant themselves.  Let the cilantro and dill and parsley and leeks seed themselves around and you never have to start those seeds again.  The little seedlings will produce good plants for you this fall and some will wait for Spring to grow.  I love it when Nature does all the work.

 

Mid-Season Garden Report Card

Mid-Season Garden Report Card

by Sandy Swegel 

Here’s the report card for my garden. June had record high temperatures and little rainfall.  Lots of extra watering helped, but plants don’t grow as well without natural rainfall.

Lettuces and Spinach. The heat made them bolt early and they are all bitter or simply scorched and gone to seed. Time to pull them out and replant.

Chards and Kales.  The chards started to bolt but some judicious removal of seed stalks and they are still growing and yummy.  The kales look great.  I didn’t know they were so tough under stressful situations.

Peas.  Pod peas were done early…they went to seed almost instantly. Sugar peas actually were not too bad.  Not as tender as usual, but salvageable….although the season was very short. Like other crops in this heat wave, things just grew really fast and went to seed.

Cilantro. Long since gone to seed.

Dill and Leeks. Leeks have gone to seed but they are beautiful.  Dill has started to seed but still usable.

Beans. My beans are OK, but neighbors have had failures from pests.  There’s still time to replant and have beans this year.

Peppers. The superheroes in our heat.  Lots of irrigation combined with heat have made them flourish.  Tomatillos too.

Tomatoes. The verdict is still out.  They are growing and strong.  Not as many diseases as I feared in a stressful year.  But not so many tomatoes either. They quit flowering in extreme conditions.  The plants themselves are shorter than other years at this time, but I’m hoping a week of cooler temperatures will inspire them to start cranking out tomatoes.

Broccoli. Little heads early this year,  but they are still producing side shoots.

Bugs. Our warm winter enabled too many pests to survive the winter, so there is an abundance of flea beetles and slugs. The greens are ugly and holey….but perfectly good to eat.  Aphids and ladybugs balanced out.  There appear to be lots of young grasshoppers but I’m pretending not to think about them.

So how is your garden faring?  Just like in school, mid-term grades are just an indicator of how things are going…not the final grade.  So get out there and yank out the struggling plants and reseed and replant in their places.  There’s still plenty of time for producing lots of food

 

10 Reasons Why You Should Prune Trees and Shrubs

10 Reasons Why You Should Prune Trees & Shrubs

by Chris McLaughlin

Practicing simple techniques, using the right tools, along with proper timing for each plant species is the key to effective pruning and most require very little pruning in order to achieve the gardener’s goal. But before taking sharp tools to your plants, you should understand exactly what those goals are and why you’re pruning them in the first place.

Remember that every cut made will alter the plant’s shape and growth. In fact, the list below addresses the many reasons that any tree or shrub should be pruned in the yard or garden. If you are interested in having your trees or bushes trimmed, remember that you can use a service like TreeSurgeon.Care to help. Here are ten great reasons for pruning your trees (including fruiting) and shrubs:

Vigor – Pruning a growing shoot stimulates new growth production. So if you’re looking for some vigorous new growth on a shrub, prune it hard (a lot). Consider this type of pruning when you have a shrub that has a weak section of growth; such as the back. In fact, when you “pinch” back new growth with your fingers on any plant, you’re actually pruning.

Shape – Plants that have grown out of balance with either the yard or their own growing pattern (such as stray and awkward branches) can be reshaped by pruning.

Restrict a Plant’s Size – This can be especially important if you live in an area with restricted space. Gardeners living in urban and suburban areas almost always have to perform some pruning to keep trees and shrubs from out-growing the yard, garden, or container. Root-pruning is another technique that can help restrict the size of plants in containers.

Let in More Light – If you have an extremely shady yard or you’d like to have more sun reaching the area under a tree for plants or lawn, careful pruning can let in a little extra sunshine.

Health and Structural Soundness – Any diseased, injured, dying, or dead branches should be removed for the health of the tree. Branches that rub together should be removed to eliminate potential damage to a main branch. Much of maintaining structural soundness in a tree is about careful pruning practices such as not “topping” trees. Topping can make the tree weak and susceptible to pests. It’s also associated with the slow death even if it takes years for the tree to actually die.

Create Special Effects – Pruning for special effects is most often seen in formal-type gardens. They often take the shape of boxwood (Buxus spp.) topiary, or an apple tree that’s been trained as an espalier. Pollarding or coppicing pruning techniques may be used, as well.

Encourage Flowering and Fruit – Pruning can coax growth spurs (produces the flowers and the fruit) to form on the branches. Strong flower buds are also encouraged to form due to pruning. Fruit trees can be lightly pruned in the summer which will provide better air circulation around the fruit. This results in less trouble with fruit diseases and the fruit ripens faster.

Protect People and Property – Trees that have been planted near homes, sheds, play structures, and other buildings propose a potential threat to human safety if heavy branches break off or the tree falls. They can also interfere with telephone or power lines. Proper pruning can keep people, pets, and property safe.

Keep Evergreens Proportionate – Pruning will keep boundary hedges under control. Evergreens benefit from light pruning as it keeps their foliage dense, and therefore, attractive.

Improve Appearance – Many gardeners’ top priority when pruning their plants is about their appearance in the yard or garden. Removing dead, unwanted branches, as well as suckers creates a pleasing shape and leaves plants looking neat and tidy. Many lovely blooming shrubs such the Butterfly Bush (Buddleia spp.) are capable of spectacular blossom displays due to good pruning techniques.

Usually pruning is about working with a plant’s natural growth pattern as it’s developing, as well as maintaining mature tree and shrub species. One of the few exceptions is when it’s used to create effects such as espalier. In general, a successful pruning job will leave your healthy, beautifully-shaped fruit trees or shrubs looking like they haven’t been touched at all.

 

The Midsummer Lull

/0 Comments/in , , , , , , /by

by Sandy Swegel

I was surfing the garden internet last night at Garden Rant http://gardenrant.com/2012/06/grazing-my-way-through-the-lull.html where blogger Michele Owens is lamenting the lull in her vegetable garden.  It’s so true, late June is a difficult time in both the vegetable and flower garden.  There was the wild early June flush of color on roses and spring perennials.  Mid-June brought peas and tons of chard and kale and spinach.  But the intense unusual heat of the last couple of weeks made the spinach and arugula bolt and the peas and fava beans quickly went hard in their shells.  Tomatoes are full of flowers and tiny green tomatoes, but there’s not much for eating.  The one exception is zucchini…The zucchini are pumping out a new zucchini or two a day….but it’s hard to find other vegetables for dinner. How can the basil be so small when I started them months ago?

The flower garden is similar. The hot season rudbeckias are finally starting but there isn’t the lushness the garden of a few weeks ago had.  First of July is a great time to notice what’s in bloom in your (or your neighbor’s) vegetable and flower garden and vow to plant that this year or next.  Ideas I’m stealing that look great in this otherwise lulling time:

Leek seed heads.  I let the leeks perennialize and plant themselves each year….so right now the flower heads are tall and a lovely pink, covered with bees.

Monarda.  Drifts of monarda are abloom…and full of bees and butterflies.

Echinacea.  Although some think of echinacea as a full sun xeric plant, it is at its prettiest with some shade and with irrigation. Some of the nicest echinaceas grow at the edge of apple trees where the extra coolness makes them vibrant.

Daylilies.  Get the camera out so you can document the daylilies you really like (in your yard or your neighbor’s) so you can make divisions next Spring.

It’s great anticipating the bounty that’s about to burst in mid-July.  Hard to believe during this lull that we’ll soon be leaving tomatoes on the vine because there are too many to eat.

 

If Plants Could Walk

/0 Comments/in , , , , , , /by

They’d run for their lives!  This week anyway.  Extreme weather conditions prevail here in Colorado and throughout the country.  Here in Boulder, we’re enduring day after day of record-setting temps over 100.  Plants are crisping just from the 4% humidity.  And as we learned in our last severe drought in 2002, no matter how much city water you irrigate with, plants don’t do as well with irrigation as they do with natural water from rain.  If my plants had legs this week, they would mosey on over to the shade next to the irrigation ditch for respite.

While we bake in the heat, my sister took her annual vacation to Florida so she could sit on the beach in the middle of Tropical Storm Debby.  Plants in some areas of the Gulf Coast desperately yearn for legs this week.  If only they could walk they would get out of the downpour of hard pelting rain and lift their feet out of the bog and mire that soil has become with excessive rain.  How’s a plant supposed to live when its roots are stuck in wet muck putrifying in the heat.

The happiest plants in dire weather can be the ones in containers with a doting human around.  My neighbor nudges her containers on wheels into the shade when the western sun is too debilitating.  Even her tomato loves the respite from the blazing sun.  Unlike my spinach, hers isn’t bolting because now that summer is upon us, she moved her containers of greens under the apple trees where cooling misters cool the greens enough they don’t have to bolt yet…and the apples grow big with the bit of extra water from the misters. One pot of summer greens was fortunate and moved inside into the air conditioning in a sunroom so the family could enjoy sweet lettuce greens a little longer.

Alas, for plants without feet, all you can do is offer some respite from the weather.  Shade cloth or row cover judiciously placed now might save some plants facing death from heat exhaustion.  If that’s not possible, a judicious mid-day misting sometimes helps.  The water mist may help the plant survive desiccation and it certainly helps perk up the gardener.

Plants that really need feet this week are the ones burning to death in the Colorado wildfires.  There are eight major wildfires in Colorado and over half of the wild-fire fighting crews in the US are in Colorado now.  We are so grateful to the men and women who come from near and far to battle out-of-control wildfires in 100-degree temps in heavy gear.  Let it rain, let it rain, let it rain.

 

The Joy of the Garden Routine

Rifling through the garden in the early sunrise hour this morning, I paused to look up at the morning sky that looked just like the ones in Renaissance paintings.  Following the beauty to the earth, I saw for the first time this year my garden in full growth and fertility.  I got a glimpse not just of weeds and tiny seedlings but of orach in its vibrant purple color and arugula in bloom.  Peas and favas are reaching for the sky and putting out delicate blooms.  Re-seeded larkspur will probably open in just a few hours.  I did pull a few weeds and start some more chard seeds on a blank patch.  But I got bundles of fresh greens for my morning juice, leeks to put in the crockpot for dinner, and magnificent lettuce for an evening salad.  The garden today has begun to return much more than I have put into it.  Tomatoes are still in walls of water and many plants are tiny, but the lovely routine of the season has started.

From now, I’ll settle into my 15 minute morning routine, slightly amended with today’s revelation.

Look up at the big sky. Look at the vitality of life between the sky and the earth.
Pull the big weeds.
Harvest the food for the day.
Fill the empty spots with new seeds or plants.
Water what is dry.
Look once more in gratitude and wonder at the big sky.

There will be times I spend more time in the garden because it’s fun or an ambitious project is taking hold.  And there may be times when I’m not keeping up with the pests or weeds that sneak in and there will be some remedial work.  But for the most part, if I am consistent in my 15-minute daily routine, my time in the garden will never be a chore but will be invigorating and full of nourishment and inspiration for the day.

 

Tough Love

Ok, your seedlings are up and growing. Whether in the ground or growing under a light, your plants have one or two sets of true leaves. You can’t wait to have a big beautiful and blooming plant.  Now you have to be brave.  You have to take that nice tall plant and cut it down.  Ouch.

The result of this tough love is that you get better, bigger, stronger plants.  The gardening term is “pinching back” because you want to get “branching.”  When you pinch back your one main stem, the plant responds by sending up two stems. Presto chango, you have doubled your plant.  Let the plant grow another two sets of leaves on each new stem and again pinch back to the first set of leaves. Now where you once had one measly little stem, you have four stems growing out and a strong bush plant.

This works especially well with basil and other herb foliage plants.  It’s also amazing with petunias and annuals you want lots of flowers from.  Even if you’re buying plants from the store, pinching back can be a good idea. When the commercial growers are producing plants for sale, they want a plant that has a flower as soon as possible because even one flower makes a plant sell. If that plant is spindly or just very full you have to be strong and even pinch back that flower.

Pinching back is only for plants whose stems are branching,  It doesn’t work for herbs like parsley or flowers like lilies.  With perennials, it’s best to pinch back before the first flower buds have started.  The only other time I don’t pinch back is when I’m willing to sacrifice the greater good of the plant for the instant gratification of flowers.  Sometimes I just need a flower RIGHT NOW.

Knowing how plants act and react is the secret to having a beautiful garden.  You can learn about how plants behave by observing them and noticing things like how they branch when you pinch back a set of leaves. There are good scientific reasons the plants are doing what they are doing.  Scientifically, you are “interrupting apical dominance” and stimulating “axillary buds.” If you want to understand plant behavior more thoroughly, one way to do that is to read Brian Capon’s book, “Botany for Gardeners”  It explains plant physiology with words and pictures that are easy to understand.

How to Manipulate Your Microclimates

/0 Comments/in , , , , , /by

by Chris McLaughlin

Whoever said “You can’t fool Mother Nature,” never met a gardener. We can and we do fool her as often as we can get away with it.  Anyone living anywhere can learn to use their unique microclimates and to take the greatest advantage of their situation.

Permanent structures such as houses, walls, and neighboring buildings can have a huge effect on the immediate area surrounding them. For instance, all of these things can serve as wind barriers or conversely, create wind tunnels. But gardeners can take advantage of the very things that would otherwise seem to be in the way.

Walls made of brick, stone, cement, or stucco will absorb the heat and radiate it during the cool night hours. Walls not only hold heat effectively, but they can also provide shelter and be a protective wind-block for plants.

The sun’s exposure can also be the difference between a perennial plant making it through the winter or not — even when its tag says it won’t survive the cold months in your zone. Bougainvilleas, for example, don’t usually make it through a Northern California winter like they do in Southern California. But there are Bougainvilleas that are alive and well in the San Francisco Bay Area because they were planted against a wall with a southern exposure.

If you’re planting heat-loving vegetables this season, be sure to plant them on the south side of your house. If you’re planning on using a wall for vertical vegetables, plant them against any wall but the north-facing one, as they won’t get enough sun there to produce well.  A southern exposure sees the longest hours of sun; a west wall will get the intense afternoon sun; the east wall will have morning sun, and a (true) northern wall will receive no direct sun.  A word of caution here: the southern side is also one of the most drastic sides for perennial plants because of temperature fluctuation during the changing seasons — it can be a circle of freezing and thawing.

On the other hand, if you’re looking for a cooler place to plant your lettuce, then go for the north side. The northern side of your house might also be the best place for early flowering fruit trees like cherries and peaches. A late spring frost will set fruit production back, and the idea here is that if fruit trees are planted where there’s a northern exposure, it can help suspend blossoming until the frost date has passed.

A good place for tender plants is on the eastern side of any structure because morning sun is the most gentle at that time of day. While sun-worshipping roses like the brilliance of the west side. Keep in mind that a southern exposure is no longer the hot spot that it could be if there’s a structure such as a neighboring building or large tree situated between your planting space and the sun. This is a perfect example of a man-made microclimate.

Use a wall’s upwind and downwind sides to your advantage by remembering the upwind side is the right place for water-loving plants as it’s going to receive more rain than the downwind side. Plants growing on the downwind side will be protected against a driving rain. This can be a handy little microclimate to have around. These are just a handful of ideas — other examples of creating microclimates is using mulch, paved surfaces, fences, balconies, and rooftops.
