I am trying to maintain a 71/2 Meyer lemon in a container in 7b. I would like to feed it organically and I have recently heard of brewed fungal tea and worm castings tea (and there are many you tube videos that suggest many other additions i.e. Kelp, etc.) I am having leaf curl and a dark midrib and these leaves are falling. I brought the tree 2 months ago so I expected some leaf fall I had a tremendous number of blossoms but they are now all brown and falling off, Im guess that's normal I did some hand pollination but I dont see any baby lemons I would love any advice - thank you !!!
