Tropical Fruit Discussion / Re: My 'Sri Kembangan' carambola

Unpruned, Carambolas get over 50 feet tall and plaster the ground with fallen fruits.  Trying to prune them at that point doesn't accomplish much, as they regrow like rockets.

Keep them small from the start, by bending branches into arches, all within easy bare-handed reach.

Long vertical splits of the corky outer bark is normal maturation.

Short splits with gummosis or running ooze are not normal, and are said to be from "abiotic stresses"--- still rather debated.

Amy K,
Spray with Copper.

4
I normally expect to apply granular fertilizer;  then anything added to the irrigation or spray is extra.

5
Spaugh's recommendation on that other thread sounds reasonable.

6
Not Potassium deficiency.  Likely salt burns/sunburns.

7
probably aphids or scales.

Nice leaf study.

I never got any viable seedlings of squamosa X diversifolia or of diversifolia X squamosa, but with so many diverent varieties to try, who knows?

9
Whitewashing tree trunks with lime is a traditional esthetic practice.  Doesn't hurt.  Helps?

10
Mangoba,
Potassium deficiency.

11
Fruit Grower,
Trunk sunburn or freeze damage,
Weed whacker or wheelbarrow damage.

Cut whole tree off below the damage to re-grow from there,
or leave as is, and
keep tree very short, until wound heals over.  It will become hollow there.

Eddie F,
One pound gypsum per two pounds 6-3-16.  The other fertilizer is not likely appropriate for mangos.

13
I don't know anything about how far seepage will go.  I imagine that that will vary per soil, etc.

High nitrogen will degrade the quality of most mangos, perhaps India-type especially.

Nam Doc Mai is tolerant of high-Nitrogen.

14
Girdling starves the roots.

Chipping just above buds that you want to grow, will probably work.

15
Copper, Calcium, and Silicon are important to strengthen wood.

16
Have you done a soil test?

17
Normal bark aging, probably.

18
Probably a mineral imbalance, such as a Boron deficiency.

19
Looks as though a large insect or snail scraped the surface of the leaf.

20
Tonyma,
Perhaps a burn from spray in very hot sun, or from pee, from a pet or tree frog....

21
I prefer to pollinate female-stage flowers on a tree when that tree's male-stage flowers are shedding pollen, or within the next couple of hours, or at the latest, when the male-stage flowers are dropping petals, which is when it would be natural for freshly exposed beetles covered with pollen to go seek out a female-stage flower to shelter in.

If you pollinate apparently female-stage flowers later than that, there may not be any remaining receptivity, especially in dry weather.

22
One should list first the seed parent, which is also known as the mother tree:  in other words, the tree with the flower into which you stuff pollen.
Then X.
Then pollen parent.

Cherilata varieties are:  Annona cherimola variety X Annona reticulata variety.  If it were the other way around, it would be a Retimoya.

Impressive!

Dead tissue, from previous infections or spray burns.
