Yes! That's what we do too, plant most of the tomato stem under the soil so it will have a bigger root system.thats supposed to have fertilizer in it already. It looks like peat from the picture. looks dry. Only thing I see is tomatoes, I plant them much deeper or even on their side.Thats a lot of work there I hope the ertilize helps. I looked up dragonfly on squash bloom and all I found was a painting from 1800s . Guess they been doing it for a long time. LOL
Dragonflies and damselflies are our FRIENDS.
