deboden, that fruit looks cool. Did you taste them? I would have wanted to make jelly!

I didn't taste since I didn't know what it was.

1. The lower leaves are yellowing. It means Nitrogen (N) deficiency. For plants 3 primary elements Nitrogen N, Phosphorous P and Potassium K are heavily required like in lbs in fields. Secondary elements Copper, iron, zink, boron etc., are required in minute quantity like micro grams. Some companies make water soluble fertilizers which have many of them. Osmocote Plus have nearly all of them like calcium, magneium. . Another is by Miracle- gro name as Tomato Ferilizer but it does nit have calcium and magesium which are normally available in ground but lesser in potting mix.

2. Buy small box of Miracle Gro , Tomato fertilizer and feed weekly. Also buy Epsom Salt fro Dollar Tree and feed 1 teaspoon in 1 liter water and feed monthly.
