LancashireQ.Why Has My Lemon Tree Got Sticky Leaves?

Certified ExpertA.This can be caused by infestation of many insects. Typically, this will be spider mites, scale, or aphids. Aphids are easily spotted. Scale is easy to spot if you know what to look for. Usually, you will see soft scale. They are flat and brown, and they can be mistake for part of the stem. They will flake off, easily when you rub the stems and bottom of leaves. There is the more notable hard scale, as well, but those are easy to spot. The worst one, however, would be spider mites. They are difficult to get rid of, and they can be hard to see. Persistent treatment will be the only way to get rid of these. These articles will go into detail:

South walesQ.Lemons Have Brown/grey Spots On Them. Like They’re Cracking
It’s been the same for a while, not getting any better or worse. We were expecting them to change to a yellow colour by now but still haven’t. Its our first lemon tree so don’t know much about them.

Certified ExpertA.I see what looks like the early stages of Citrus scab. This is primarily caused by two different species within the genus Elsinoe. These would be E. fawcetti and E. australis. Either one will require the same control methods. Fungicides and good sanitary practice will be the way forward.
This isn't the only issue that I see, though. I notice what looks like a mild powdery mildew infection. This will have similar treatment to other fungal pathogens.

556273Q.Lemon Tree Losing Leaves While Blooming
My Lemon tree is blooming but losing leaves. I live in Minnesota so it is inside and getting southern and western sun exposure. Should I be fertilizing it. I have put some coffee grounds on top of the soil.

Certified ExpertA.Yes. Fertilizing would be a good idea. Coffee ground don't have enough to satisfy the nitrogen hungry nature of citrus trees. You may want to test your soil for exactly what to add, then feed accordingly. A fertilizer meant for citrus will usually do.

February 15, 2025Q.Production Of Lemon
Sir I have a lemon tree which bears fruit both in winter and summer season I want to make it very big breed it but this lemon is seeded I also like it because its peel is very thin And the water is too much, but the people who gave it to me say that it will have to be grafted. This species will not be produced from its seed, but I don't even know its species, what type it is. So, is this true because those who gave it to me they have lemon orchards for 30 years and this is the only lemon of their generation that they gave me as a gift. Will be waiting for your reply.

Certified ExpertA.Most lemon trees are grafted. This enables the tree to grow and produce much quicker than if it was produced from seed. Trees grown from seed from a grafted tree will not produce the same as its parent. Grafted trees have a "stock" tree for its roots and a different tree variety for the canopy.
You can try reproducing the tree with a graft if you can locate a suitable rootstalk. However it is labor intensive and requires skill. These articles should help:

February 18, 2025Q.Does My Lemon Tree Have A Disease?
My lemon tree's leaves have always had a problem turning yellow, and I always thought it was a magnesium deficiency. Today, however, I found some brown spots on a branch and think that my plant has a fungus or disease. Problem is I am having trouble identifying it. I am hoping you guys can help. Much thanks in advance.

Certified ExpertA.There could be several problems going on such as insects, overwatering, or fungal issues. Spraying the plant with Neem oil should get rid of any pests and it could help with a fungal infection, too.

10Q.Is This A Rootstock Sucker On My Lemon Tree?
Hello! I’m new to fruit trees and needed some tips and advice on taking care of my Lisbon Lemon Tree. I was wondering if this was a root sucker? Should I prune it? Also, some leaves on top are light green and have white dots what should I do? How should I help my lemon tree become healthier?

Certified ExpertA.Yes, that trifoliate branch is part of the rootstock. You'll want to remove that. The white dots are likely indicative of a spider mite or aphid infestation. Sucking insects tend to cause these issues. It is sapping nutrients from the tree, as you can tell from the discoloration. Azadirachtin, and Pyrethrins. Both are plant derived, and my go-to.

April 5, 2025Q.Is My Lemon Tree Dead?
I got this tree a year and a half ago, last spring it was full of leaves and produced a lovely big lemon. since last fall its been down to sticks, but recently new leaves have started to grow at the base, is it just teasing me and will soon be green again? thanks a lot

Certified ExpertA.Most likely that was a grafted lemon tree (I see a bulb in the trunk above the new leaves). Scratch off some trunk or stem bark above the graft. If it is green, there is hope for survival. If it is white, the upper part is dead. The graft rootstalk may grow but the resulting tree would be inferior to what was grafted on top.
