Make Your Own Biodegradable Seed Start Pots
Luckily for procrastinators like me, it’s not too late to grow some seed starts. Mine only took one week to sprout. This year, I only wanted to start seeds for two plants for my back patio: sunflowers and ornamental gourds from calabash seeds. As any good DIYer, I made some seed pots that will decompose in the ground as the starts take root.
First, I folded some easy origami boxes from newspapers. I used one layer of newspaper but then realized that it was too floppy to hold the shape. It works much better with a few layers. The gourd seeds went into these pots with some potting soil mixed with compost. I asked Matt to make a multiple-egg omelet so I could use the halved egg shells and then I propped the shells upright in the egg carton. I planted the sunflower seeds in these.
I put the pots in a big casserole dish and gave them a strong dose of sunshine and twice-daily watering. (The painted rocks are there to keep the dish from sliding off the step.)
A week later, I had healthy starts to plant in the ground. The gourd starts are not as visible, but I have faith they’ll rally.
And into the soil they went, pot and all. I’m told I may have to crunch up the egg shell when the roots become a bit more established since the shell won’t decompose fast enough. My soil is very healthy though with plenty of microorganisms so I am pretty confident the seed pots will break down.
I tossed the wet, soggy egg carton straight into the compost bin. Total investment: oh, maybe $3 for the seed packets.
