Guerilla Gardening: Reclaiming Urban Spaces Sustainably
Step 1
Gather all the materials from the list and bring them to your workspace.
Step 2
Spread the newspaper or tray on the table or floor to keep things tidy.
Step 3
Scoop about 2 tablespoons of wildflower seeds into the mixing bowl.
Step 4
Add 1 cup of compost or potting soil into the bowl.
Step 5
Add 1 cup of natural clay powder into the bowl.
Step 6
Sprinkle about 2–3 tablespoons of water slowly over the dry mix.
Step 7
Stir the mixture with the spoon until the ingredients are evenly damp.
Step 8
Press a small pinch of the mixture to make sure it holds together as a firm pinch.
Step 9
Roll the mixture with your hands into marble-sized seed balls.
Step 10
Arrange the seed balls on the tray or newspaper and let them dry for 24 to 48 hours.
Step 11
With an adult, choose a pot or a community-approved spot for planting.
Step 12
Press each dried seed ball about 1 cm into the soil of the pot or spot.
Step 13
Water the planted seed balls gently so the soil becomes lightly moist.
Step 14
Add a small label with your name and the date to your pot or planting spot.
Step 15
Share a photo and story of your finished seed balls and planting on DIY.org.

Help!?
What can we use if natural clay powder or compost are hard to find?
If natural clay powder is unavailable, substitute sifted garden clay or powdered bentonite from a garden/pottery supplier, and if you don't have compost use an extra cup of potting soil mixed with a handful of well-rotted yard soil when adding 1 cup of compost or potting soil into the bowl.
My seed balls keep falling apart or are too sticky—how do we fix that?
If seed balls crumble, follow the instructions to sprinkle water slowly and stir until evenly damp then add a little more clay powder and knead until the pinch test holds, or if they're too wet let them dry longer on the newspaper/tray before rolling into marble-sized balls.
How can we adapt this activity for younger children or older kids?
For younger kids, have an adult pre-measure the 2 tablespoons of seeds, 1 cup compost and 1 cup clay and help press larger marble-sized seed balls, while older kids can measure ingredients themselves, try different wildflower seed mixes, control drying for 24–48 hours, and press each dried ball 1 cm into soil before labeling.
What are simple ways to personalize or extend the guerrilla garden project?
Personalize by making separate batches with different wildflower seeds, writing names and dates on small labels for each pot or community spot, decorating the label, and sharing photos and a growth story of your seed balls on DIY.org.
