Good day, adding this post to this thread instead of creating a new one since my query seems to fall under the heading. I did some grafts of mature mango scions onto a seedling mango a week or two ago since it's a couple years old but has never flowered, and I was checking them a couple days ago. The ones I have checked so far haven't taken, but more importantly I noticed what appears to be some sort of dieback on the leaves. It's affecting a fairly significant number of leaves too, has anyone had anything that looked like this?



I should mention that the dieback has been there for a while probably, I just never actually looked at the leaves specifically so it didn't come to mind. The leaf parts that haven't died still seem healthy, so not sure what's causing the partial dieback. No sooty mold or other fungal problems on the tree that I'm aware of, although there's an older established fruiting mango about 15-20 feet away that doesn't have the leaf partial dieback issue but does have some sooty mold on a couple lower branches. That one seems to be growing fine overall though and is presently flowering.

Yea sometimes it's a waiting game lol, is that yellowest one from your tree too? Also ours aren't shriveled so not sure, do you water the tree?

GUAVAS ARrrrghhh.

My first year growing ruby supreme and pink were pest free, had lots of delicious fruit but the next year scale got to them big time.

I really like them but till recently have had terrible luck with scale that I could not control.

Not long ago I started using horticultural oil in addition to strong stream water spraying and hand scraping scale off and I seem to be gaining some ground.

My lemon and strawberry and Alahabad (the Alahabad has not fruited) all seem immune to scale but do get fruit fly larvae so the fruit get bagged.

My pinks, and Mexican have rebounded and set some fruit. The ruby supreme (my fave) is hanging on but no fruit. My Thai white languished so I put it out of it's misery.

So, being a glutton for punishment I found a silly expensive 3 gal. Barbie pink hoping to make a go of it.

This is my last ditch effort to have guava, fingers crossed.

I thought there was a program in Florida for the eradication of the fruit fly?

My best friend and I both have a Violette De Bordeaux fig in a pot for about 3 years now and both our trees produce lots of super tasty figs on a small bushy tree. If you look up VDB, most pictures show a tiny fig but with good fertilization and watering, the fig gets much larger. Here are some pictures of a couple VDB figs that are almost ready, they are not fully black yet. In certain months, the figs are much smaller, this is the first crop of the year and I started harvesting a couple weeks ago.

That's pretty impressive Simon, what size pot is it in?

Ciruela is the local name? The red ones are starting to ripen up here already, while the yellow ones here don't ripen till closer to the fall, maybe late August or September

Since you're in coral springs, you very likely have 6 - 12 inches of 50 / 50 mix (sand + muck) on top of limestone rubble. You can lower the pH of the top 6 - 12 inches, and that is sufficient for feeder roots of your trees which normally only dwell in the top foot of soil.

If you have a normal 1/4 acre lot, 50 to 100 pounds of sulfur is good. But be very cautious around annonas -- go light on those, as they seem to be sulfur sensitive. The other species don't mind sulfur.

You may not need iron. The soils that I've had tested in this area (northern broward) have sufficient iron. You just need to get the pH down.

Consistent application of a complete fertilizer (with micros) does wonders.

None of what I've said above applies to most of Dade county, where marl is the most common soil.

Just fertilized it today. I can throw some sulfur on it to. How much? My soil has a lot of limestone so don't think it's going to reduce the pH substantially.
What about iron drench?

So what would apply?

In South Florida, it is a year round battle with leaf miner.  I recommended to drenching the tree, and any other citrus you have, with imidacloprid 3 times a year.  The affected leaves will not change but the new flushes should come out clean.  I would also add to your regime to spray with copper fungicide.

Are you using the same strength as per bottle directions, but 3 times a year, or a third as strong as one bottle-direction application but thrice yearly?

If the male tree you intend to get the branch from flowers around the same time as the female tree, most likely the mwle branch will also flower around the time as the female branches of the tree once grafted onto the female tree.

My Soncoya, going on two years.

What's this mulch round the tree?

Mark what do you use to measure the pH of your water after you add the acid?

PR you bananas look very nice; do you still use the system where you pile grass into an open-bottom garbage bin in the center of a block of mats for fertilizer?

7.5 to 2  lol.

I don't think I'm aiming for quite that low lol, but I collected a couple trashbags worth of casuarina needles the other day to try laying down around some of my fruit trees so hopefully it works well. Most of them have grass right up to the trunk so I'll probably have to put down something to smother them under the needles.
