Battling various basil issues
A friend gave me a pot of Basil and it's apparently not so easy to grow. It took me a while to get the hang of how often to water it, but then everything started yellowing and dying.
After some examination, I realized I must have spider mites, since there are tiny specks that walk around and I notice some dry leaves hanging by some webbing.
So far, I have been trying to combat it by spraying it, but that doesn't seemed to get rid of the mites. Today, I decided to just soak the whole plant underwater for 45 min reasoning that should drown the mites (but probably not their eggs, so it'll need to be repeated).
While waiting for the basil to dry, I notice that the base of some of the leaves are turning black. Is this cause by the spider mites or something else?
