The Tropical Fruit Forum

The spinosad product I have says you can only spray citrus a few times per year; most other crops can be sprayed more frequently. I have no idea why.
The ultra pure HO I have is a 16oz bottle, bought several years ago, tho.
Can you actually see thrips? I thought they were too small; I just look for the distinctive damage pattern

 Between nagami and meiwa, I find that nagami gives you a juicy sweet/tart experience, whereas meiwa seems to be all rind/pith. My trees are container grown and more than 6yrs old. I prefer the nagami, but this year I should have my first fukushu to try.

Here is my volk. I think the petioles do not match

I've had this (ungrafted) limequat since 2016. Had a few small crops off of it.

Last year, plant had many flowers, I didn't get fruit. I had been spraying nearby plants with hort oil and figured that was the cause, but I believe I had a second flower flush with no fruit. Don't recall if there were fruit that formed and fell off, tho. (you know how tiny quats are)
 
Plants are all crowded closely on my deck, so now I move the flowering ones when I spray hort oil (big hassle). I might try covering with a light cloth, but that could damage flowers.

But even being so careful, the limequat appears to be doing the same this year. It just finished flowering (a lot!) but I only see 2 tiny fruits.

I have other plants flowering and setting fruit.

The only other thing I am wondering about is the rootball. I have repotted twice since getting this, and the root mass is very dense at the top of pot, you cannot get a finger stuck into the media. Despite that, the plant does not seem to suffer from watering issues. I am basing that on the foliage, but I do know that water is especially important around flowering.

What could I do about the dense root issue? I have run a metal skewer through from the top of rootball to create channels, fwiw.

Plants get urea and Peter's 25-5-15 and this plant looks very healthy otherwise.

(p.s. I did stain my deck last season, so that horrible peeling you see is because I used a new/inferior stain )

Took me 4 years to get a single fruit from my Harris Sunquat.
 
53 ounces. 9 segments, 2 seeds
Good orange flavour, plenty of juice, not very sweet. Peel thin and somewhat bitter.
I didn't get anything lemony from it. Still a young plant, of course.

I wonder if other sources are different hybrids and thus more lemony?

I put my trees under grow lights during the winter. The conditions in the grow room are very similar to what you listed, especially for branches close to the lights.

Can trees die from damage of spider mites?

Spider mites can definitely kill a plant.
Also, some spider mites do not make webs, they just look like little specks of dirt.

Two of my container citrus (kumquat hybrids) wilted rather suddenly like this, and I still have no idea why.  Roots look fine, soil is free-draining, they are in the same greenhouse with a hundred other (mostly citrus) plants that are perfectly healthy.  But on these, the leaves wilted up and the branches are now dying. 

I would check root temperature for sure, though.  The soil might be much colder than 55F, and possibly going long periods below this temp so roots may become inactive.

Yup, same here. I have more quats than other citrus, but I've had this sudden wilting thing happen a few times on the quats. I have yet to pull a plant out to look at the roots, I rather doubt it would actually tell much.
Very baffling.

Yes it still has the empty pill shells.  A shame, but I don't know of a better slow release option.  If you have a suggestion let me know

Brian, not trying to bash. I'm getting more lazy as I get older and consolidating my ferts. I've used Pro Gro Citrus and Avocado for last 4 years as my base fert. Does not last nearly as long but I add it monthly for potted plants and use it per label for in ground trees. I just don't want to mess with those plastic balls in my yard. Another chore for me!

Thanks for including the photos in your post.

So, is everyone using slow release in addition to another fert? I thought many of us were using just Peter's 25-5-15 ?

I too dislike the prills - a lot of the plants I am getting now (not citrus) have green prills. Yuk.

Before grafting did the twigs spend any time in the refrigerator, perhaps in the Crispr drawer.

good one!

If there is little risk to treating for phyto. with sulfur, you might want to try that.
Hard for me to see your pics, but I had a mostly clear, gel like, substance that looked like distinct blobs. I assumed it was an insect issue, did no treatment, and the plant is still alive. I had previously seen similar stuff on a kumquat fruit where a caterpillar had eaten into the fruit and left the blobs ‘behind’.

I recall sumos being somewhat more expensive Than other citrus, at grocery store, but was shocked to see them at $3 per fruit this year. I have yet to try one. I’ll just stick with my ridiculously expensive kumquats.

Grocery store had these on sale, 5 for $1, which is a great price.
I've eaten 4, and they sure forgot the "sugar" part. Some of them are dry at the top, as well. But certainly easy to peel. All of them had one or 2 seeds
