This summer we decided to experiment with kitchen scrap gardening. These are two celery scraps from the same package, each cut an inch from the root. We used organic because it’s more likely to grow.
On May 13, we put one in a shallow bowl of water and the other we dipped in rooting hormone and planted in an equal soil mix of presoaked peat, organic compost and citrus/cactus potting mix. We covered it with about a half-inch of the soil mix.
Celery needs a lot of nutrients and good drainage, so that’s what I came up with from the bags in my garage. I have no idea if that’s proper or not, but I needed something for container gardening. It gets too hot here to grow celery this time of year so it needs to stay on my windowsill to keep it from bolting and turning bitter.
I didn’t think the one put in the soil was going to make it at first because the other one had an inch of leaves in a week, but it looks like the one planted in the soil was putting its initial energy into making roots because it really took off. On the other hand, the articles I read on rooting celery said you should see roots in a week if you put it in a bowl. We decided to give up waiting and gave it some rooting hormone and soil. Hopefully we’re not too late.
This is how they looked June 4.
In theory, if they don’t bolt, you can cut off what you need when you want to eat it, or you can cut off the tops and bury the stumps in a little soil and start over again indefinitely. We may try blanching them with tubes of construction paper later.
