Maybe you can find a cherimoya to graft onto the unknown anonna for now and if the seedling fruits turn out not to your liking, you'll still have a cherimoya. I do it to all my seedlings: graft a known cultivar onto a branch.

Behl, sorry to hear about your lychee. I have a couple good-sized ones you can take scions/buds from if you want. They're Hak Ip and Mauritius I think.

I think you should put a bag over the whole pot, put it in a cool, shady place, and stop watering or giving it anything for the next month. I lost many airlayers in the past and a large plastic trash bag is one of the most important tools for their survival in the first 3-6 months in SoCal conditions.

Nice collection you have. I always like to see what people in cooler climates do to grow these things.

Pomegranates are mostly not tropical, except for Ganesh. Many like chill, like those from Russia, Yugoslavia. Maybe you can plant one of those in the ground. They're pretty drought-tolerant in the ground.

2879
That's a lot of effort and very impressive size. Mine in SoCal are still growing the nuts, not expanding yet.

2880
As I recall the 2" sections stretched enough to do more than 2 citrus buds. But if you have a long scion to wrap or the trunk diameter is large then maybe non-perforated makes sense.

But I use parafilm for those purposes: 1/2" wide to wrap scions and 2" wide to seal wide cuts.

Lemon juice? Ascorbic acid (vitamin C) is what some urban aquaculture people use to neutralize chloramine in tap water.

Nice looking passion fruit, makes me want to try to grow this. Not sure if it would do well in Southern CA.
Someone's growing it in Rainbow. It does well for him in a greenhouse. As I said in the other passiflora thread the guy is hard to find. He hand pollinates and sells fruits to high end restaurants.

I'd give it a try if I can get a few seeds.

Do you know if the Chinese variety is as stinky as the Indian?  I'm growing Chinese jujube.
I have not heard of Chinese jujube smelling, but the flowers are so small I never tried.

Keep a plant of Osmanthus fragrans next to it might help? Tiny flowers that fills the air with fragrance, and you can use it in tea.

Is Thai giant related to Indian jujube? I've only had experience with the Chinese kinds and they're good both fresh and dried, depending on the variety.

2885
A nice collection you have there. Does Montreal get about the same amount of summer heat at Toronto? I have family there and all they grow are squashes and peppers and tomatoes.

I tasted a strange fruit there for the first time, too.   The fruit is black, conpletely round & about a bubble gumball in size.  It's sweet, but not too sweet & have 3 small seeds.  Do you know what it's called?

Is it a jaboticaba? Looks sort of like a shiny grape usually with thick skin.

Tropical Fruit Discussion / Re: Good grafting knives?
« on: June 19, 2012, 07:58:56 PM »
I also heard of people using utility knives with replaceable blades. A sharp straight edge is what you need. I'm not sure what curved edges in budding knives are good for. I know about using the spatula edge on the back for lifting bark.

2888
Toronto Robert? I'm interested to know what you're growing. We have an introduction thread in the forum for it.

I saw this thread too late. I would have gone shopping there on the weekend. Or maybe I should go to Mimosa instead since that's closer

Behl, PM me your location where I should pick up.

Tropical Fruit Discussion / Re: Dragonfruit: how best to support?
« on: June 17, 2012, 01:05:02 AM »
For me my support is thin and I let a single stem go up each one. Maybe growers do several just in case one gets damaged by animal or disease.
If you grow in containers like me you have to think about how many plant you want to compete for root space.

To make it more difficult, did all of Selenicereus get lumped in w/Hylocereus or just S. megalanthus?

-Ethan

Only megalanthus was reclassified into Hylocereus. Selenicereus normally has more than 3 ribs, so megalanthus is closer to Hylocereus. There may be other factors but this is the most apparent.

I have about a dozen kinds but I lost some interest in these. They don't take much work so I just leave them be.

Guatamalan types:
- Santa Barbara Red (collected wild from Central America)
- Condor
- American Beauty
- G2 (part of Paul Thomson's original wild selections for crossing, thin compact vines)

Unnamed:
- H. polyrhisus
- H. megalanthus (yellow)

Paul Thomson's hybrids:
- Halley's Comet
- Physical Graffiti (fastest growing)
- Delight
- S8 (Voodoo Child, Arizona Purple)

Whites:
- George (George Emerich the father of cherimoya in CA)
- Quang Ong's white (my name for where it's from)

Others:
- Valdivia Roja (mexican origin from Valdivia ranch, small but numerous fruits, very good tasting, waxy rough texture bluish stem)
- Sin Espina (no spine)
- Purple Haze
- Zamorano
- Tricia (Ed Valdivia's daughter, elongated fruit, deep red flesh, polyrhisus with tendency to alternate between 3 and 4 ribs)


Guatemalan type has clearly lobed ribs with magenta-fleshed fruits and good sweetness. This is the type that was said to be more frost resistant earlier in the thread.
H. costaricansis is interesting and taste can vary from bland to slighly cucumber to very sour. The deep red flesh is very appealing.

I like Valdivia Roja, Halley's Comet, Voodoo Child, and the Guatemalan ones.

DF aerial roots provides only marginal adherence to rough surfaces. Even Vietnamese farmers with rough concrete posts. have to tie them for stability.
I think its role is for nutrient absorption than for support, unlike ivy or creeping figs.

Jack Vincent of Oceanside used 2" PVC for his plants before he had to give them away. His 2 plants were over 100lbs each after he cut 200-300lbs off of them.

The 4 foot horizontal PVC of his trellis was bending when I saw it but it was holding.

2895
I use a Nesco circular dryer with double walls and the dryer unit on top. It's a good design but I don't have an excalibur to compare to. I heard great things about Excalibur from people who dry much more fruit that I do so it should be good also. I went with the not too cheap but just good enough.

2896
Oops, my earlier post should have said tynanwyatt@aol.com for the person who's doing the importing. I'll fix that post.

I'm basically repeating what Tropicdude wrote but... The idea is to concentrate nutrient supply from the soil to very few stems. Let it get to the desired height and then produce fruits from all the horizontal branches.

Since light plays a large part in blooming, too much branch-stacking should be avoided. Experienced Taiwanese growers are very good at pruning where they keep stacking to a minimum and also remove diseased and really old non-fruiting branches.

I'm still trying to get mine from March stabilized. I've been looking at getting other possible rootstocks. The seed place I found is out of stock on it for now.

Cutting at the top of the trellis is right. I was just commenting that the trellis need not be so tall.

Depends on the variety. The thicker ones tend to be more susceptible to frost. The main problem is ice crystals which cause cell walls to burst and the plant melts, leaving behind a central cane.
