Say what? Well, Spring weeds ARE my friends. August weeds not so much. But Spring is finally overcoming winter and the big leafy weeds are the proof.
So what’s to love about Spring Weeds? The most important thing is they are an abundant source of food for pollinators. They are also delightfully pretty if you don’t think of them as weeds. I especially love the wild mustards. Invasive in lawns and on bare garden soils, blue mustards’ very tiny blue flowers are everywhere and are an excellent food source for awakening bees. Bees can’t live on dandelions alone you know.
To a gardener, the best part about spring weeds is WEED TEA and COMPOST.
Weeds, especially the perennial ones like dock and thistle, are an excellent source of nutrients because of their deep tap roots. To capture these nutrients in a usable form, you have to break down the plant tissue. The easiest thing to do is just keep throwing the leaves on the compost pile. This time of year your compost bin has too many “browns” anyway with all the dead winter material. The “greens” of spring coupled with warm weather jump-starts your pile.
But if you want to really get all those nutrients available to your plants and soil, you’ll want to make some Weed Tea.
Weed Tea Recipe
Get a big container. A Rubbermaid garbage can will work, or make a small batch in a 5-gallon bucket. Put in all the weeds you can gather. I throw in cut leaves and whole plants. Put this container someway far away from your back door where you can’t smell it!
Here’s what’s going in my bucket:
Yellow dock leaves…these are everywhere.
Pulled or dug thistles.
Comfrey if you have it….these are especially full of nitrogen, phosphorus and potassium.
Nettles. Wear gloves.
Crabgrass with clumps of dirt still attached.
Dandelions, salsify, prickly lettuce, even bindweed if it’s up already. Nothing’s going to survive this stew.
Now fill your container with water at least 12 inches over the plant material. And let stand until it is a disgusting gooey stew of fermented and stinking rotted material. Stir weekly. That smell is anaerobic decomposition. If the weather is warm, this takes maybe 10 days or as long as 4 weeks if it’s cooler. That’s it. You’ve made the best fertilizer you will ever use. Capture the liquid to use to pour directly (I dilute about 1 part weed tea to 4 parts water) on your garden beds. Strain some and put it in a sprayer for foliar feeding. Hold your breath and throw the stinking mess of weed material on your compost pile.
My favorite use of weed tea is to use it as a foliar feed and watch the treated plants green up overnight. This is especially good on tomatoes. Spring Weeds really are a gardener’s friend!
