Temperate Fruit Discussion / Tree Blueberry?
« on: November 24, 2017, 03:36:20 PM »
Check out this video around 22:30. Shows a 20' tall tree blueberry. Is it really a blueberry? Viking guy posted about something similar ages ago but I didn't imagine the trunk being so robust.

Southern California folks interested in mangoes might want to check out Exotica in Vista. Looked to me like he has over 1000 plants now. He's expanding into the back lot and has a couple greenhouses full of mango too. I didn't even try to read all the tags but it has to be many tens of different varieties. Id guess mostly from Florida but a few from california. Very expensive.

Tropical Fruit Discussion / Best under ripe mangoes

This has probably been covered but didn't see it in a quick search.

What are the top mangoes that taste great even when not ripe?

He asked me to post. The "e-mail me my password" doesn't seem to be working for him either. Anyone know how to fix it?

Protects our fruit and seedlings

I was trying to grow a hedge, but it wasn't happening, so I have 15 plants between a few inches and 1 foot up for grabs to anyone who wants to stop by. Or if you're close enough to where I work or live. Mostly seedlings from fruits I enjoyed, but I don't know which is which. Most in heavy clay (in pots).

Also a couple extra Senna bicapsularis buttercup.

Tropical Fruit Discussion / Baobab self-incompatible
« on: February 08, 2017, 01:29:56 AM »

The African baobab's (Adansonia digitata) breeding system has not been experimentally verified, and it remains unclear why such a stark disparity exists between ‘male’ trees that produce few, if any, fruit, and ‘female’ trees that produce many fruit consistently year after year. Combined results from gene flow analyses of 26 trees scored for nine microsatellite loci and hand-pollination experiments on five trees across three baobab populations in Mutale District, Limpopo Province, South Africa, investigated the breeding system, strength of incompatibility within trees, and if genetic differentiation was detectable between ‘males’ and ‘females.’ Our data suggest that A. digitata is largely self-incompatible. ‘Male’ and ‘female’ trees showed high heterozygosity and estimated outcrossing rates did not differ in degree of self-incompatibility, and showed no significant genetic differentiation. The ability of ‘males’ to produce fruit if cross-pollinated suggests that poor fruit production in male trees is most likely due to low rates of pollination.


Citrus General Discussion / new issue of topics in subtropics out
« on: August 02, 2016, 08:51:31 PM »

• “We Shall Defend our Citrus, We Shall Fight in Backyards and Community Gardens, We Shall Fight in Organic and Conventional Citrus Orchards; We Shall Never Surrender.”

• Organic Control of Asian Citrus Psyllid is Challenging

• Citrus Clonal Protection Program (CCPP) and National Clean Plant Network (NCPN): A Model System for Management of Citrus Diseases

• Discouraging citrus varieties smuggling by offering easy access to pathogen-tested budwood

The last piece is really good.

Tropical Fruit Discussion / Fruit ID from costa rica
« on: July 25, 2016, 10:03:12 AM »
In Costa Rica right now. Getting to taste lots of new fruits. Found an unknown in a gutter. Big, smooth and yellow with flesh like an annona. Smelled like a lemon custard pastry fresh out of the oven. Waiter at restaurant that owns the land said guayaba china, but thé seeds were huge. Anyone recognize?

Tropical Fruit Discussion / Bioswale mix as potting media?
« on: July 14, 2016, 08:57:11 PM »
One of our local mulch/soil suppliers has something called bioswale mix. 50% sand, 25% sandy loam (topsoil) and 25% humic compost (screened). I used it to replace a section of what I believed to be contaminated clay. I'm wondering if it'd be good as potting media? Heavy and maybe too dense? I don't think it'd have the drainage of gritty mix, but infiltration seems pretty good where I have it.

Tropical Fruit Discussion / San Diegans -- Exotica heads-up
« on: June 20, 2016, 10:27:45 PM »
Place has cleaned up quite a bit, prices are up too, but if you're interested in Mangoes you should stop by Exotica. He's got dozens of varieties, most of which I'd never heard of. 'Peggy' was a name I recognized. Some 'California Grown' too, which are not Thompson's and seem to be grafted from locally successful trees. That's as much as I remember. If anyone else goes by would love your impressions.

Temperate Fruit Discussion / Caper
« on: June 03, 2016, 10:35:57 PM »
Anyone have experience with Caper? Mine has been flowering like crazy for a couple months, but not a single fruit. I'd like seeds...

Tropical Fruit Discussion / Hawaii visit
« on: April 26, 2016, 09:26:16 PM »
Just returned from the big island. Started with the suggestions I got here and got more tips there. Got to visit a couple forum members, which was very cool. Seeing the trees around the island was neat, especially the feral mangoes growing huge alongside the roads (and the ones at Rainbow falls...holy cow). And the Jackfruit and Breadfruit.

For tasting new fruits the farmers markets were mostly a bust (tried 5 different ones), but the roadside stands delivered. Two in south Kona, one in front of the old theater and another a couple miles further down the road. I got to try for the first time: star apple, rollinia, tree tomato, soursop, ugli fruit, some orange dragonfruit (a megalanthus hybrid?), cocoa fruit pulp. Was a bit early in general though.

Pretty productive in my book. Plus other adventures/siteseeing.

Tropical Fruit Discussion / Any chance of this LZ recovering?
« on: March 27, 2016, 04:42:49 PM »
Planted a couple Mangos in the ground 18months ago. The NDM#4 died after a few months. The LZ started showing similar symptoms last summer. browning leaves tip dieback. Mostly from the top down. Didn't progress all winter and I just cut off a couple of the dead branches. There's a dark patch in the middle of the wood and when I cut down a couple more nodes it looks even worse. So I'm guessing fungal rot from the roots. Can it survive and flourish, or is it done? Is there any treatment?

Tropical Fruit Discussion / Yard highlights Spring 2016
« on: February 28, 2016, 03:07:21 PM »
Really excited about all the growth this spring, only the 2nd or 3rd for most of my plants.

M. cauliflora, Jaboticaba likely 'Sabara'. Was looking ugly, dropped all of its leaves and flushed new ones while I was gone 4 days:

Glycosmis pentaphylla, Gin Berry. Suffering from nutrient deficiency. Flowering quite a bit.

Seratonia siliqua. 2nd season pruned Carob seedlings getting ready for some more espalier training:

Eugenia uniflora. Surinam Cherry from Ethan, stays green most of the winter:

Vermillion seedling from Leo, amazing red during winter. Some flowers open right now:

Multigrafted Almond (cut way back to deal with last years fireblight). Two nectarine, two peach and one pluot graft:

Espaliered Anna Apple in foreground and Hood Pear in background:

Myrica rubra. Yangmei from Rtreid, pushing like crazy:

Fuerte avocado flowering

Chandler Pomelo just about to flower

Casimiroa edulis. Aggressively 'pugged' Suebelle white sapote pushing out. Kinda wanted this one to die so I could give its spot to a mango, but will give it another chance to grow bushier. Was horrible infected with lace bugs when I pruned it:

Seedling hawaiian papayas loaded with fruit. Also note the 3 inches of mushroom compost  :)

Dovyalis caffra. Female 'silber' kei apple with new leaves at every node:

Bunchosia argentea. Peanut butter tree pushing lots of new growth.

And looks like it might be pushing its first flower buds:

Tim Thompson's 'Pineapple' mango, about to flower in my greenhouse area:

Temperate Fruit Discussion / Non-legume nitrogen fixing, Frankia
« on: February 08, 2016, 09:06:00 PM »
I haven't seen a discussion here of the non-legume nitrogen fixers. Fascinating group.

Most of them form nodules with Frankia species actinobacteria (as opposed to the rhizobia that symbiose with the legumes).

Some fruiting examples:
Yangmei (Myrica rubra) and others in the Bayberry genus Myrica. Not only do some produce edible fruits, but many produce wax that was used to make candles.
Guomi (Elaeagnus multiflora), Hardy Silverberry (E. commutata) and others in the genus Elaeagnus (e.g. russian olive, E. augustifolia)

Some natives/ornamentals:
Alder, Alnus
Wax myrtles (Myrica californica, M. cerifera), used by some here as rootstocks for yangmei. Anyone tried M. hartwegii?
Ceanothus species
Mountain Mahoganies, Cercocarpus

Many of these nitrogen fixers are pioneer species in inhospitable conditions, which makes sense. Can be invasive.

I just planted goumi and hardy silverberry. Very different root systems. Guomi has a mass of multi branched thin roots. Did not notice any nodules. The Hardy silverberry on the other hand had 3 larger roots with few side branches and several obvious large nodules.

I see lots of posts on TFF regarding actinorhizal plants, but not much discussion of nodules, nitrogen fixing, inoculation, etc. E.g. Goumi (Eaeagnus multiflora), E. latifolia, E. pyroformis

Anyone else fascinated by these guys?

Temperate Fruit Discussion / Most exotic for 8B?
« on: January 07, 2016, 09:10:07 PM »
Looking for some interesting and preferably drought tolerant fruit/nut trees for 8B (-10C). 10yr min is around 8F (-13C).

I know there's plenty of apples/pears/stone fruit and even citrus. How about more exotic? Che, Yangmei, other chinese temperates? Anything from Africa?

And what would be good candidates for attempting some selection?

Going to give a shot at different oaks, chestnut, mulberry, che, yangmei, and kei apple. Probably opuntia. Pindo palm.

Any others?

Tropical Fruit Discussion / Naranjilla pluses and minuses
« on: January 03, 2016, 03:32:48 PM »
Had my third fruit from my naranjilla. Tastes just like cape gooseberry to me but none had any sweetness yet. Last one was off the ground.

Besides the unimpressive taste theres the fuzz covering on the fruit and a too long rippening time that took all the way into winter. On the positive side bugs mostly leave the fruit alone (unlike cape gooseberry) and its a beautiful plant esp when young and well watered.

Got my first lone ripe orangeberry (gin berry) today. Tasted like pine with a hint of something else. I guess that's the turpentine people complain of in Mangos and surinam cherries. No sourness. Only very mildly sweet. I liked it. Fruit was smooth, salmon colored and translucent. Flesh was thin over a large seed (relative to the fruit) and came off freely.

Tropical Fruit Discussion / intergeneric grafting update
« on: October 08, 2015, 09:51:40 PM »
Quick update on my attempts to graft fruit trees on common landscape plants. Its mostly been failures, but from single attempts by a novice grafter, so inconclusive.

Fig on Ficus Benjamina failed.
Longan on carrotwood (approach graft) failed.
Rose apple, java plum, wax jambu, surinam cherry on brush cherry (approach grafts) failed.
Mango on california pepper tree, sugar bush, lemonade berry bush failed.
Natal plum on tropical milkweed failed.  :)
Kei apple on Xylosma failed but fused first. Will try this again.
Jujube on coffeeberry failed but leafed out twice first. Will try again.
Yangmei on wax myrtle failed, but others on the forum have gotten this to work, so will keep trying.
Apple and pear on hawthorn survived (not surprising since other hawthorns are known to accept apple etc) but haven't thrived.
Apple and pear on ornamental (bradford) pear have similarly survived but not thrived.

First real success is loquat (Eriobotrya japonica) on hawthorn (Rhaphiolepis indica). Did it with some friends in their yard. Looking great. Not entirely surprising (bronze loquat is supposed to be a hybrid of taiwan loquat and india hawthorn), but I haven't seen mention of it anywhere before. Loquat on quince is supposed to be dwarfing.

In the picture you can see the other pear and apple grafts there and not doing much while the loquat is growing like crazy. Graft is 9 months old.

Doing some housecleaning and want to get rid of a stackable composting bin as well as some seedling/small plants: babaco (x3), lemonadeberry bush (x2), sugar bush x lemonade berry hybrids (x5), soapberry, ackee (x2), torrey pine (x2)

Free for pickup in north san diego county. PM me to arrange.

Tropical Fruit Discussion / Sapodilla fruit drop, chicle damage, roots
« on: August 06, 2015, 08:56:43 PM »
Is it a bad idea to plant an Alano next to a driveway/sidewalk in terms of either fruit drop or root damage? Or sap?

Tropical Fruit Discussion / delano sapodilla?
« on: August 03, 2015, 10:32:52 PM »
Picked up a sapodilla/chico sapote ffrom california tropical fruit trees today. Tasted very good. Nothing very different from others ive had but smaller, which i like. Guy said it was a 'delano'. Anyone heard of it?

Also had some tastey brewster lychee, sabara jaboticaba, and rose apple.

Tropical Fruit Discussion / Sindhri Mango
« on: June 17, 2015, 08:02:33 PM »
Anyone ever tried one of these? From Pakistan. Managed to get my hands on some seedlings. Pictures online look a lot like manilla. One of them did have two tap roots. Polyembryonic?
