What kind of tree is it?Are they the only fruitlets on the tree or are there many more? I have seen my trees fruitlets turn brown and drop before (not that reddish color) and just drop as part of the tree self thinning, I am not sure if that is what is going on here.

Well, first there was a heavy flower drop, then a light fruit drop, and now most of the remaining fruit look like this! I'll go out and look more carefully!

I had a lemon tree years back whose fruit had a slight pinkish green tinted fruit when tiny (somewhat like the flowers were), but once the lemon grew bigger than an eraser they were all green.

Oh, Fruity Paws, I hope that happens to my little guys too! Will keep you posted!

KC, assuming that this is a small tree and not all of the fruits dropped; it should be ok. I try and limit my young trees to no more than 3-5 fruit. But, that is very difficult with some lemons and so the number balloons to more like 12.

As the tree gets larger, it will be able to support more fruit. While young, it is desirable for it to focus on growing the canopy and root system. - George

Hey George, nice to hear from you! It is not one of the smaller ones, it is taller than I am, so over five and a half feet, and has been in the ground at least 4 years! They meyer next to it which had fewer flowers and fruit has held on to all of them. I'll watch and see how it goes, keep your fingers crossed!

What kind of citrus is it?

It's the one I had never heard of, called Mexican sweet lime! Dunno if that means it is a lime or an orange, because the internet tells me both!

KC, I will go out and inspect a potentially similar tree; my Mary Ellen Sweet Lime [MESL and a.k.a. Lima] and see if it is displaying any of such behavior. It is in a spot that gets only 1/2 day sun at most.

My small tree has been in and out of the ground and currently in a pot, it's been the victim of multiple moves due to my frequent citrus musical chairs activity. and BTW: it has not been very productive at all. the reaction to the taste of fully ripe fruit this past January... "tastes like an apple".

Thank you! Jontte, I hope you are right! I'll watch and see if the fruit grow at all! George, thanks, I would appreciate that! Mine get sun from about 10 in the morning to about 5 or so in the evening, so essentially the hottest times of the day! This is the first year I have any fruit at all, so I have nothing to compare with!

Really, greenman? That would be a relatively easier problem to handle!

Well now. my 10-11 ft. tall Millsweet Limetta is displaying young fruit with a slight purple tint. The fruit that seems to be dropping has a reddish tint. It has been a bit under watered, but not drastically. I think all looks normal.

BTW: My Persian lime, MaryEllenSweetLime, Mexican Lime, nor any of the lemons have any red or purple tint.

Interesting. Thanks for sharing Molewacker, i'd love to know what other trees do this too.

I only notice it on my variegated Eureka lemons. They start off a pale color, and develop that tinge in the sunlight. You can kind of see it here.

Yay, that sounds promising! Thank you, George and greenman, you are the best!!

I have a quick question, guys. My lemon tree's new growth is purple, it was not purple when it was growing indoors. How do I know what type of lemon it is? I don't know because at the time of purchasing it the seller did not specify the type of lemon (I am talking about my citrus salad tree that has orange and lemon branches).

Sunshine, that means it is well fed : - )

My Lisbon, Santa Theresa, and Meyers all push new growth with a heavy purple color when they have been fed enough N.
