I will be helping someone dig out an existing tree (crepe myrtle) to replace with a citrus tree. I think at least 2 feet depth will need to be dug out to remove the existing tree with some roots intact. The native soil is sandy. Ideally it would be good to obtain native soil from the area, but I don't think that's possible. Therefore I am thinking of mixing 30% buffered coir and 70% washed sand for replacement native soil. Then I will plant a bare rooted citrus tree in this replacement soil. This is to prevent roots circling around a nutrient rich potting mix but to help with moisture retention and to prevent too much compaction. Will my plan work or should I go with a higher proportion of washed sand?

These are all leafs from the SAME lemon tree. From top to bottom I see: -leaf miners -aphids -whitefly -nutrient deficiency or sooty mold

Just a guess though. Can anyone tell me if I’m correct? Seems like a lot of issues for ONE tree :(

Heya, short little post here.

I was curious if there are any good databases or registers for citrus species/varieties/cultivars? For many of my other hobby plants these are readily available, but I haven’t had an easy time finding something for citrus. Would be cool to know what people have hybridised or bred.

I always thought it’d be interesting to see if someone bred a Cara Cara with a Moro, or some similar combination of high lycopene with high anthocyanins. Or to look into hybrids/varieties incorporating less common species, like the Australian lime, “Clymenia”, and “Oxanthera”.

Anything is good - I could use a starting point at the very least.

Need to whitewash my trees have around 40 trees. Have anyone used this before?

Hey all,

My meyer lemon is dropping leaves like there’s no tomorrow. Leaves are dropping at the petiole which made me suspicious of overwatering/root rot. I haven’t watered it in two weeks though…

The leaves aren’t helping me either because I see signs of both over and under watering.

I checked the roots as best as I could and they seem to be tan-ish so they don’t look like root rot as far as I can tell

Any ideas?

I’m trying trying to treat an iron deficiency but the spray doesn’t seem to be changing the leaves at all I will try watering it in next time but would be good to know for future

In an attempt at giving it more calcium

I’ve purchased some semi dwarf mandarins (owari, tango, kishu) and a Meyer lemon and bearss lime. I hadn’t originally planned on something in this spot but it would have good access and it would be nice to create some shade after we took out the ficus (stump shown) a few years ago.

If I removed some of the surface roots from the old ficus, and created a raised planter of sorts or at minimum a mound how would a citrus tree do?

Hello, sorry if someone has asked this before. I was wondering about how trifoliate rootstock affects plants grown in pots/containers. I live somewhere with pretty heavy, slightly alkaline soil that stays moist most of the winter yet people have trifoliate planted outside and it does well on this kind of soil. Since a big number of citrus plants are grafted on trifoliate does this mean that they should be able to tolerate these similar conditions? I usually see people here recommending that citrus soil should be light, well draining and slightly acidic, also that citrus hates wet feet and constant moisture. Does grafting on trifoliate change this?

I didn't read the label carefully and I sprayed copper fungicide on my mandarin and grapefruit tree in a concentration for trunk application only. This was about 50 times more than the concentration for foliar application. This was 2 days ago. Yesterday I noticed the new leaves on my grapefruit had wilted. The older leaves seemed fine. My mandarin only had older leaves which seem okay. Today I realized what happened and rinsed the trees with my garden hose thoroughly. What's the likelihood that my trees will die?

Hi all, black aphids observed on my mature lemon tree. Second day I’ve observed two on the lemons, presumably sucking the juice from the fruit. Are the lemons still safe to eat as they ripen? (I’ve sprayed them with diluted vinegar to scare them off and have a bio citrus pest spray coming)

Hi, r/Citrus!

I've had the California-grown "Sumo" and I'm wondering how it compares to the fruit from the same tree grown in Japan as "Dekopon" and in Korea as "Hallabong".

Has anyone tried more than one and can speak to any differences in eating qualities?

Thanks!

This is my Mexican lime tree. It was planted around a month ago. It is a young tree. It is planted in the ground. It lives in the Arizona USA Southwest with me. It has a drip system on it. The tree is 56 inches tall. It has a 3 foot 1 inch by 2 foot 4 inch spread. It has been pruned and fertilized. What is the minimum amount of gallons of water I should water it with per watering? I am very confused about how much water to give it. Please advise me what I should do here.

I noticed this on my satsuma tree at first I thought it was rabbit damage but I am not sure. Should I treat it with some thing ? Zone 9a
