Dany: There’s more than just one type of lemon.

Zach: There’s more than just four types of lemon.

Dany: True that. Zach is here to help me with four problems with lemon trees. You ready Zach?

Zach: I’m ready.

Dany: First one is this one. Look at all these weird, crinkled, messed-up leaves.

Zach: Yeah, this is an easy one. It’s a leaf minor damage.

Dany: Okay.

Zach: Leaf miner is a common ailment of citrus and lemons. It is a caterpillar that gets between the layers of the leaf, makes trails and causes that leaf curl.

Dany: It must be a tiny little caterpillar.

Zach: It’s very tiny.

Dany: But this is not really that detrimental to the plant?

Zach: No, it’s actually, it looks worse than it is. The leaf can still perform photosynthesis, but if you want to get rid of it you can cut off the affected branches or a good preventative is foliar sprays with molasses.

Dany: Okay, nice. Yeah, because that’ll drive it away and protect it.

Zach: Definitely.

Dany: But you have to do that before it gets on there?

Zach: There’s the rub.

Dany: There’s the rub. Okay. Some of these, this, I had this at my lemon tree, but the chlorotic or lightening of leaves.

Zach: Yeah, you can see it on the lower leaves first, so it’s a nutrient deficiency. That tells me that your tree needs some feeding or fertilizing or it’s just deprived of some mineral or nutrient that it craves.

Dany: Okay, and what’s a fertilizer you would use? Oh, we have MicroLife Citrus & Fruit right here.

Zach: Yeah. MicroLife is an excellent fertilizer for all citrus and it has those minerals that we talked about.

Dany: Okay. The next one is cold, are they cold-sensitive?

Zach: They can be cold-sensitive. Lemons are not the most cold- sensitive of citrus, but they, if we get a freeze, they can be effected and die back a little. Something to be aware of with citrus in general, is that if you’re getting it from a nursery, chances are it’s going to be grafted. You can see the graft here on this variegated lemon. Okay.

Dany: Yeah. Mine has one over here too on this-

Zach: Yeah, they’ve all got them and it’s something to be aware of is, you don’t want any growth below that graft.

Dany: Okay.

Zach: Because that’s a different plant.

Dany: Got you. That’s not the same fruit that I have on the top.

Zach: They’re using a more resilient root stock to get these plants to the stage that they need to be to fruit.

Dany: Okay. Awesome. Any other pests involved with citrus?

Zach: A big one, I think, to consider is a scale.

Dany: Okay.

Zach: That can affect them. The number one way you tell you have scale can be actually black sooty mold, which appears on the surface of the leaf from the bug that’s actually on the bottom of the leaf. It makes an appearance like a black film on the top of the leaf and the scale are little gray or white dots on the bottom. Fortunately we don’t have any to show you.

Dany: That is good. That is good. Last thing is, we have four different varieties here. There’s more than just one type of lemon.

Zach: There’s more than just four types of lemon.

Dany: That’s true. That’s true.

Zach: We’ve got a variegated lemon here. It’s a variegated pink lemon with a pink flesh when it fruits. We’ve got your standard, improved Meyer lemon, which is a sweeter lemon but super disease-resistant. Then, finally over here I’ve got a Eureka Frost lemon, which I really like because it can give you multiple harvests in a year.

Dany: You guys also have the New Zealand lemon, which is a real cold, hardy lemon as well.

Zach: Yeah.

Dany: Awesome. Well, thanks Zach.

Zach: Thank you.
