Update- The Cherapu lost the remainder of its leaves and things looked grim for a while. Fortunately, the plant is making a comeback. Several new leaves have sprouted.
Peter, thanks for the correction. I viewed a lot of Cherapu pics yesterday including those kindly sent by DBSS_DavieFL and found several that closely resemble my leaves. I'll assume they are genuine.
Tru, I spritzed the leaves with 70% alcohol. The dark smudges did dissolve while the black spots remain.
The Garcinias are watered with water from my room dehumidifiers. I've ordered a new pH meter as mine was inaccurate. Any suggestions on how moist the soil should be? I've found that my Luc's prefers to be fairly damp while the Achacha is happier a tad drier.
Cassowary, they are in a mostly-shady, very humid environment. An occasional dry wind is a always a possibility but none of the other plants seem to have been affected.
Although I don't see any sign of Thrips, I don't see a downside to spraying the plants with oil.
Tru and Ognin525, what pH water and soil should I be using?
The plants are in pots as shown, on an island with nearly non-stop ocean breeze. Achacha, Lemon Drop, Imbe, Cuban and Luc's Garcinias are all nearby and doing fine.
Any chance it's too much or too little water?
Brian, a PM was sent with the source. However you might want to wait until Peter's concerns are addressed.
Peter, you have far greater experience with these plants than I do. What would you guess they are? Any way to determine what they are other that waiting to see flowers and fruit one day?
Attached are some pics: The top stem has some white specs The underside of a leaf shows a white line and some black spots The top side of a leaf shows some black and white specs
They are fed diluted Fish Fertilizer (5-1-1) every 2 weeks.
If this is salt sensitivity I'm in trouble as I live in the Florida Keys.
Thanks, Nyuu. That article says that cross-pollination is needed. Does anyone know if the cross-pollinator needs to be the same variety or would a Red Jaboticaba work?
My Jaboticaba Vexator flowered last year, but no fruit. It is flowering again and I am hopeful, but was wondering if male and female Jaboticabas are required to set fruit?
Aaron- I would expect the entire plant to exhibit nutrient deficiency symptoms, not just one branch at a time. But I don't see a down side to trying micro-nutrients so I'll try it.
Lebmung- We're in the Florida Keys and haven't had a cold snap in a very long time so I don't think that's the cause.
Cookie Monster- You may be correct and I'll just have to accept it until a solution is found.
I have a Pitomba growing in a 10 cu-ft planter. About once a month a branch dies as shown in the second pic attached below. Any idea of the cause? The plant has doubled in size in 2 years and occasionally sets a few fruits.
I am growing 1 red and 1 green finger lime plants in a large planter. Although they are growing the leaves are pale and yellowish. Any suggestions on possible nutrient deficiencies that could be the cause?
This Nam Doc Mai mango was planted early this year and was growing nicely. It looked good.
About 2 days ago 2 of 3 branches started to droop, and now they appear dead. Where the leaves connect to the branches, and where the branches connect to the trunk, sap is oozing.
Can anyone identify the probable cause and any solutions?
Ignore the black strings in the pics, they are holding to plant to the stakes.
Hello again, Today I was cutting a rotting branch off a Cogshall Mango and and found this worm (borer?) inside the branch. Any idea what it is and the best method to eliminate it?
Thank you Har. I have looked up pics of Mango Scale and you are correct. I initially tried to simply wipe the white spots off the mango leaves, but they came back. In this forum you have suggested Neem oil and Insecticidal Soap as remedies. Does liquid Sevin work? I also found a link suggesting Bayer Tempo SC. Any experience with this?
