Why this matters
Egg cartons make perfect free seed trays, giving each seedling its own little cell. Starting seeds this way saves money and gives plants a strong, healthy start.
What you need
An empty egg carton, soil, seeds, and a little water.
These are everyday items. If you don’t have one, look for the closest alternative — the steps will tell you what to use instead.
How to do it
Follow these steps in order. Take your time. You’ve got this.
Fill each cup of the carton with soil and press a seed or two into the centre.
Water gently to dampen the soil and place the carton on a warm, bright windowsill.
Keep the soil moist, and once seedlings have a few leaves, plant out the whole cup in larger soil.
Your one thing today
Save your next empty egg carton and fill at least a few cups with soil and seeds.
Don’t wait for the perfect moment. Do this one thing now, even if it’s small.
