Seed Bombs for Earth Day

This post comes directly from Marcie Cuff’s blog Marcie wrote “This Book Was a Tree,” my favorite book about exploring nature with kids. 

Seed bombs are magical little nuggets of clay, compost and native seeds used to surreptitiously improve areas you’re unable to reach.

DSC_2534-300x200To determine native species in your area, ask a smart friend, or visit the Native Plant Database. My family and I live in the Northeastern U.S., and our seed bombs include (among other seeds) eastern red columbine, red milkweed, butterfly weed, New England aster, joe pye weed, lanceleaf coreopsis, blazing star, wild bergamot, sweet coneflower and rigid goldenrod.

Select low-maintenance drought-tolerant native species that can thrive with intermittent care. As mentioned previously, choose seeds wisely. You certainly do not want to select invasive species that will threaten biodiversity. Consider species that create habitats for other native critters like butterflies and birds.

To determine your soil type, do the squeeze test: take a handful of moist (but not wet) soil and give it a firm squeeze. Most likely, one of three things will happen:

  • The soil falls apart as soon as you open your hand. This means you have sandy soil.
  • The soil holds it’s shape, and when you give it a little poke, it crumbles. This means you have loam. Perfect for a garden—it retains moisture and nutrients, but doesn’t stay soggy.
  • It holds it shape, and when you give it a little poke, it sits stubbornly in your hand. This means you have nutrient-rich clay soil. Perfect for this project.

DSC_2534-300x200If you have dreams of a yard-ful of annuals, perennials and veggies, yet have the horrible misfortune of heavy clay soil (I can relate), today you are in luck. There is little need for clay amendment in your seed bomb recipe. Just head to your backyard and collect some clay soil. If your soil is sandy or loamy, however, you must add natural clay (often found in natural stream banks), terracotta clay powder or air-dry clay (found in art supply or health food stores).

Like making a mudpie, making a seed bomb is not an exact science. Use the below recipe as a guide, but your measurements needn’t be exact.

Seed Bomb Recipe

– 3 parts clay (see note above)

– 3 parts dry organic compost or worm castings

– 1 part small native perennial seed

– 1 to 2 parts water (added by the Tbs)

The mixture should be moist, but not wet. Knead it with your hands, being sure to incorporate all seeds. Roll it into 1 to 2 inch balls. Set them on newspaper to dry for 2 days before using, or store on a sunny windowsill before throwing over a fence. Your seed bombs are ready to wreak havoc on green wastelands. Just throw and they will grow. Rich in nutrients, the clay and compost aid in germination and help strengthen plant root systems.

Nicely packaged in a handmade bag, seed bombs make fantastic handmade gifts for friends, family and teachers. Include a nice note or quote like one of these:

Don’t judge each day by the harvest you reap, but by the seeds you plant. –Robert Louis Stevenson
Weeds are flowers too, once you get to know them. –A.A. Milne

Once there was a tree, and she loved a little boy. –Shel Silverstein

The greatest secrets are always hidden in the most unlikely places. –Roald Dahl

Sometimes the smallest things take up the most room in your heart. –A.A. Milne

Small as a peanut, big as a giant, we’re all the same size when we turn off the light. –Shel Silverstein

Once you have perfected the seed bomb, you may get the urge to branch out and attempt other small-scale unlawful acts. Do not mention my name during your interrogation!

Now, Joanie or Johnny Appleseed, plant something already!
