Question
As a chef, my edible garden is very important to me. I currently hold a SE exposed patio in SOMA with good light in the absence of fog. I grow many herbs and a dwarf Meyer lemon tree. Any recommendation to increase the crop and longevity of growing delicate herbs? Also, my lemon tree shows slightly yellowing leaves. I'm guessing lack of nitrogen and other trace minerals? The tree is producing several new flowers and buds. I'm worried the small tree cannot produce or support too many whole sized, ripe fruits. Shall I prune and reduce the crop size? Cheers.

For herbs: you may want to plant more of what you use most. I am thinking you mean things like Basil, parsley, chive, and thyme. To encourage herbs to resprout more quickly after a pruning, feed them with a liquid fertilizer 1/2 strength every time you harvest. I like to plant herbs in 3's. I rotate the harvest among them and it ensures I have enough when I need it.
It is common for citrus trees to yellow up, especially over the winter. We like the Growmore Citrus Growers blend which contains all the trace elements Citrus need. You can supplement with the E.B. Stone Citrus Food to provide more nitrogen. Citrus are notorious for producing more fruits than they possibly could support. The plant will thin itself when the young fruit is the size of green peas. There is no need to prune other than to shape.
