From the page: The shell that turns into gold in the garden
Idea 2
Biodegradable seedling trays
Traditional seedbeds have always used trays and cups that had to be discarded at every replanting. Half an eggshell solves this elegantly: it protects the seed, holds moisture and, being entirely mineral and organic, goes straight into the earth along with the seedling, with no stress on the roots.
What you need
- Eggshell halves about two-thirds of the height
- Egg carton or ice cube tray to support them
- Seedling soil or light substrate
- Small seeds (lettuce, basil, cilantro)
- Small spoon or dropper for watering
How to make it
-
1
Crack the egg carefully to keep the larger half intact and rinse quickly inside, letting it dry before use.
-
2
Fit the half shells into the carton, which serves as a firm nursery and also absorbs small excesses of water.
-
3
Fill each shell with substrate almost to the edge, leaving room to water without overflowing.
-
4
Plant the seed at the depth indicated on the package, usually twice its size, and water with drops or a sprayer so you don't unearth it.
-
5
Keep it in a bright spot and maintain moisture daily, because the shell dries out fast for being porous.
-
6
At transplanting time, make a light crack in the shell by squeezing it with your fingers and bury everything together, letting the roots break through naturally.
Finishing touches
The shell also becomes calcium in the replanting hole, so the seedling takes its fertilized "crib" along. Start a new batch every week for a continuous supply of seedlings.
