Bumps on bottom of collard green leaves?
« on: April 26, 2020, 04:01:46 pm »
Hello!  I planted my second earth boxes a month or so ago.  I've been having trouble with the collard greens and was hoping someone might know how I can remedy this situation:
There are some bumps on the bottom of the leaves that just recently spread drastically.  I'm attaching a photo of the bottom side of one leaf as well as the top side of the leaf and a photo of the earth box that they are growing in.  I did a little internet search and the only thing I could come up with is that it's edema of the leaf - yet I don't know how to remedy it since I'm using the earth box as directed for planting.  I grew collard greens in an earth box before with the same growing medium and did not have this issue, so don't know why it's happening now.  Anyone know what is happening to these leaves and know what a solution might be?

Also, ever since I planted them I've had to keep picking little green worms of caterpillars off that have been eating holes in the leaves and feel I have been able to stop them from destroying the plants if I pick them off EVERY DAY.  I was trying not to use any chemical insecticides so just went  the hand-removal method.  I've read that neem oil, etc, can help, but didn't know if I wanted to ingest it.  Just thought I'd also mention this as this is ALSO not a pest issue that I experienced with my last collard green earth box adventure. 

Had such great luck with collard greens in the earth box before and would love to have the same results once again!

Thank you for any suggestions or advice!   :)

For the worm issues use spinosad, Captain Jack's Dead Bug Brew, it's organic
Why Google, when you have me?
