Citrus General Discussion / Please Help! Meyer Lemon Defoliation!!!
« on: March 07, 2020, 02:30:35 PM »
For the past month and a half, my Meyer lemon tree has been gradually losing its leaves. The leaves will turn completely yellow the fall off of the tree. I bought my lemon tree back in September from Lowe's and it was doing perfectly fine and was full of blooms. This is my first citrus tree, so I didn't quite know what to expect. As fruit started to set on the tree, I started to notice leaves turning yellow all over the tree.

I fertilize every two months with Citrus Tone and since the leaves began turning yellow, I have been feeding my tree with fish emulsion drench every two weeks, thinking that more nitrogen would benefit the leaves. I also cut off a lot of fruit from the tree thinking that would help with decreasing the stress. Well, now my tree is defoliating.... I only water my tree once a week to avoid root rot and it gets full sun outside. The only factors I can think of would be the normal cold winter weather in Tampa Florida (has not been less than 40 degrees). Also, I noticed that at the base of the veins for each leaf, there is a dark area. It does not look like any particular pest I can see, but I am thinking maybe it is a fungus?? Please take a look and let me know what you think.  :'( :'(

Tropical Fruit Discussion / Young Mango Tree - Help!!
« on: September 13, 2019, 11:40:04 AM »
Hi all, a couple of months ago, I bought a young Cogshall Mango tree that I have kept in a container in the yard. I live in south Florida and we have also had a lot of summer rain here. It is about 3 feet tall at the moment. It has access to full sun, is watered every afternoon currently, and is in a soil that is meant for good drainage. I used a cactus/palm soil and repotted into a larger pot than what the nursery had it in, keeping a lot of the previous soil also. I am currently not fertilizing my tree as I was advised that the soil it was in from nursery should have enough for a couple of months, so I know I need to start soon. Have no idea what organic product to use after trying to read up on it, I was told 8-3-9 is best, but cannot find an organic fertilizer with that ratio. The tree had some dark spots on it when purchased.

Recently I have noticed that some of the younger leaves are starting to discolor, black dots are found on the leaves, and on a couple of the leaves, you can see a small clear strand extend from the underside of the leaf with a white dot attached to it. I think I may have some sort of pest infestation brewing, but I have no clue what kind of pest or what multiple PESTS are affecting the tree and how to combat them. I also think it could be something fungal happening at the same time with all the summer rain we have, but I'm trying to figure out the pest situation. For 2 weeks in a row, I sprayed it with Monterey Disease Control once per week, and it does not look any different. I have tried to research the cause, but I am bombarded with information and it's overwhelming. Spider mites? Leaf miners? Fly larva? Can anyone take a look at the photos and please try to identify the issues with my young tree? I don't want to lose it without a fight! Any thoughts or recommendations on fertilizer and ideas as to the issues would be appreciated. Thank you!
