I have finally started my seedlings; I know it's a bit late in the season and I hope it wont effect them too much. I have not planed seeds in years and this year I decided to try something different. I did not want to use those plastic trays that are bad for the environment and I didn't want to spend a ton of money on eco friendly seed trays... So I made my own!
First I made two boxes to hold all of my individual seed cups. I used the box that a juice flat comes in (I got this from work but if you shop at whole sale clubs they should have some there). First I wrapped it in a layer of cling wrap and them a lay of foil wrap; I covered both the bottom and the inside just in case. I don't want water leaking all over the place.
Next I made the seed cups. I used toilet paper and towel rolls, you could use any sturdy cardboard roll. I cut the toilet paper rolls in half and the towel rolls in thirds. Next I cut four slits, about one inch long, on the bottom of each. I folded the cut end in on themselves and taped them using masking tape, sort of like wrapping a present. Now the little seed cups can stand up on their own, even if some are a little wobbly.
I filled them with soil and them planted my seed like you normally would. I also labeled each cup with the sort of seed I planted in it. When the seedlings are ready to be planted I can just remove the tape and plant them or I can remove the seedling from the cup and then compost the cup (after removing the tape). And the components of the tray I made are all recyclable
I hope this works!
