I’ve had this plant for two years. It hasn’t grown at all. Once in a while it would grow a set of new leaves. Then almost invariably the tips of the leaves would dry and turn brown. Eventually they would drop and a couple of new leaves would appear. It’s not growing and not dying either.
This is hybrid red jaboticaba that I got on Etsy because supposedly it produces faster than other varieties. I was inspired by @aap 's pictures.
I hate growing stuff in pots because everything has to be right. I would plant in ground for growing season. Not sure your climate but I keep citrus alive in 7b with c9 lights and frost fabric. Zone 6 or lower probably have to dig up again
Jaboticaba needs a lot of acidic water, p/h 5 or 51/2 no strong fertilizer, mostly compost and peat. Saucer need showing water. Espoma holly tone fertilizer works good. No hot sun, partial shade. Don’t need a big pot at that size, 5gl is plenty big, wait till they take of. A bag of Happy Gro compost is a good start.
I find Red Jaboticaba about the easiest to grow. I get usely 3 yields through the year.
I germinated two seedlings about a year ago of M. vexator (“blue grape” or “false jaboticaba”) and one of them was very vigorous for a few months and the other was a runt. Same conditions, same soil, watering, light, etc. Then one day the vigorous one just keeled over without warning, looked like yours but worse and died in about a month. I might have let it get too dry when the greenhouse was hot in the late summer, and then it just couldn’t recover.
The runt kept growing slowly until fall, and now looks pretty sad after a winter in my greenhouse (lows in mid to upper 40s for most of the winter and spring so far), having lost a bunch of its leaves. But looks like some new buds may be swelling! This is it today:
You didn’t mention temperature and humidity. I gather jaboticabas like humid air, more humid than your average home. Is it in a greenhouse? Does it get misted regularly or have some local humidity source like a nearby humidifier?
Have you ever tasted it? Is it something worthwhile to grow? It looks really cool. I keep my house on the cooler side in the winter, around 67°. Some of my house plans do not really like that, due to the tropical origins. I’m wondering if it would die in my house because of the cold winters (if I were to try to grow it)
I ordered my seeds from Tradewinds and they came moist and clearly fresh, though I’ve heard other people have mixed results. They have a lot of species to choose from, you could get a LOT of seeds for $80:
If your tap water is 7 to 8 pH and aap is stating that Jaboticaba needs 5-5.5,then it could be twenty times too alkaline.It sounds like these plants need to be treated like Blueberries in that sense.
All it might take,is to use some rainwater or add a little vinegar to what’s coming out of the tap.
I’ve tasted it from the tree in Emma Prusch park, planted by CRFG folks. I heard it fruited after 17 years They say it tasted like muscadine grapes and I’ve never tasted muscadines before. I can say that it does taste closer to a grape but nowhere near the flavor of modern grapes. It has slip skin and dispersed seeds, so same effort as eating Concord grapes. Of course, this is one tree that’s grown from seed and one season (although I went back a few times to see if the ripeness is different) of fruits. The tree and fruits attached to the stem look cool though.
