I'm growing Solanum pennellii again this year. This is the third year for me. They have not thrived for me, but last year they produced seeds. They seem to have little delicate root systems, and don't seem to do well in my potting or garden soil. Last year I had some success with keeping them in the greenhouse, and spraying them every day, because it seems like in their natural habitat they are watered by fog.

This spring, I transplanted seedlings into various types of soil, compost, sand, coir, etc. The most successful was a batch of compost made a couple of years ago from mostly squash fruits. The least successful was my standard coconut coir potting soil. Woot! perhaps S. pennellii will do better for me this year. I'm intending to grow them in pots in the greenhouse.

I'm also intending to attempt grafting S pennellii onto Jagodka root stocks. Jagodka grows vigorously and quickly for me and thrives in my garden soil.
