Thanks again, I will do that

Thanks for your reply, I will definitely look into that Foliage Pro ASAP and see how often I should apply. When I water her, the water drains through pretty well. I have a soil mix of organic potting soil, mixed with some additional perlite, and some pathway bark to help with the drainage. I recently shimmied her out of her pot just to examine her roots and they all looked to be yellow and nothing that looks like it's rotting. What do you think about the darkness on the underside of the leaves?   

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.  :'( :'(

You tree looks like it is lacking Zinc, Magnesium, Iron and maybe Manganese. You may want to add a bit of Sulfur if youíve been getting a lot of rain considering you are using a cactus mix.

A Foliar feeding and soil drench should fix the problem but you may want to plant your tree into the ground, ideally in full sun away from the shade of your fence.

If you keep it in a pot, give it a good quality smart or slow release fertilizer. When you water it, water until there is about 10% excess water runoff in order to avoid nutrient lock.


Thanks, Simon. Unfortunately, I am renting, so my only option is to keep my tree in a container until I settle down somewhere in a couple of years. But I will move it away from my fence. :)  Sulfur powder? Mix it into soil? Is there a particular foliar spray you recommend? What about soil drench?

Also, was thinking of changing the soil to this one:

Which organic fertilizer would you recommend using? Any of these appear suitable for mangos?

1. Your finger isnít long enough or good enough to check for moisture
2. Spend 10 dollars on amazon and buy a moisture meter because it works great.
3. You may be shocked by what it reveals

Thanks, that sounds like a great idea, I'll pick one up and test the mositure level

Hi, thanks for your advice, the soil that I purchased was a mix from Hoffman's.

And to clarify, we have been getting a lot of rain on and off. So for a week straight it'll rain every afternoon and then the next week, the harsh sun will be beating down constantly. I do make sure to stick my finger all the way into the soil to check if there's moisture and when there is still moisture, I will refrain from watering that afternoon. I check to water my tree everyday, having read before that they have susceptibility to root rot if watered too often. The soil seems to still hold moisture pretty well, but after two full days, I will not feel much moisture at that top part of the soil when I test it and that's when I'll water it. Otherwise it's been raining so much.

The strand with the white spot at the tip is a green lacewing egg. The larvae of green lacewings are voracious predators of aphids, spider mites, etc. The can eat 400+ aphids in a few week span.

Thanks, I'll make sure to leave those be!   :)

Multiple nutrient deficiencies.

What nutrients would these be? thanks

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!
