Citrus Newbie Questions
Hi all, a couple of questions from a beginner gardener. I recently brought home two dwarf citrus trees (one Meyer lemon and one Mexican lime) in 5 gallon containers. They've been living on my porch for two months and have been quite happy in the mild South Bay weather, producing some new growth and leaves, many flowers, and even some fruit.
A week straight of rain, however, has left them with some sooty mold, powdery mildew and some unidentifiable bright yellow dusty thing. I've started to spray them with Green Light Rose Defense which was recommended by the nursery to guard against aphid and spider mite infestation (as well as a leaf miner infestation which has been going on since about two weeks after I got them). However, I've also noticed that the trees are really not getting as much sun as I though they were. In late summer/early fall they were getting about 5-6 hours of full sun, but now I think it's down to 3-4.
In light of this change (pun definitely intended) and the presence of molds, I was wondering if maybe a grow light would help. I would like to keep the plants outdoors since I'm concerned about the indoors being too humid and about the possibility of bugs living in the soil. As such, I wouldn't want to leave a grow light on outdoors while not in the apartment for safety reasons, so I was thinking of just turning on the light for a few hours after returning home from work. Does this sound like a good or bad idea? I wasn't sure if maybe plants prefer continuous light to: natural light then a patch of darkness then sudden grow lamp light for a couple hours before returning to nighttime dark. If it sounds like a go, any recommendations for what type of light/wattage?
Or, should I bring it indoors and keep it under a light throughout the day? If so, are there any tips I should follow for preventing bugs/mold hitching a ride on the plant into my apartment?
Thanks in advance.
