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.

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.

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.

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.

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.

Karen, notice how stressbaby cut the growing tip at the top of the trellis to promote horizontal growth. It looks a little too tall to me or it could be the perspective. You don't want it to be too tall or you'll need a ladder to prune it in the dormant season. 4-5ft is a good height. Expect horizontal branches to be 3-5ft as well.

3066
Joe did you bag them in plastic? I hear it helps tropical cuttings like mango in our dry climate.

Yes, tropical cactus receive a lot of rainfall in nature in Central America. They climb to the top of the forest canopy and can survive just from water absorbed through aerial roots and stems.

Thanks. This will be useful in 2-3 weeks for me.

if you have a container of some kind, you can slice them up, then put a layer of fruit to a layer of sugar, then just add more layers when you have more.
Phuc, I have done this with extra grapes a few years back and it worked well. The difference is the grapes became more alcholic than the liquid on the outside. Which way you choose to go depends on whether you want only the liquid wine or wine along with the fruits.

Samuel, unfortunately Patrice is one of those people that do their own thing and don't mingle with groups like CRFG. "The only thing rare about CRFG are the growers themselves.":) I met him through a mutual friend as he was finishing his trials on growing P. alata and preparing to grow them in large scale. I'll find out how to contact him. His place is findable by GPS coordinate only because all the roads for several miles have the same name.

Sorry I didn't know there were 2 photos. The first looks like a new vine. See the 3 funny leave above the fruit and along the vine where the flowers have fallen off.

Yes I think that's a flower. Flowers grow right after you see the 3-leaf pattern. There should be a special name for them but I don't know it.

For the San Diego chapter www.crfgsandiego.org, there's normally topics on propagation, white sapote/cherimoya, mango, citrus, pomegranate/avocado, and a couple that varies from year to year. Maybe soil, pests, pitaya, rainwater harvesting...

For North County San Diego nc.crfgsandiego.org, the topics are more varied these days. Permaculture, dates, gophers, blueberries, cactus fruits.

The San Diego chapters tend to stay away from apples and temperate stone fruits. But the last-minute annoucements of special meetings are the really amazing ones. Some speakers have only short windows of stay in San Diego and they had to reserve a room on short notice and inform members with the news.

California is Mediterrainean weather so anything that don't normally grow in this area or this climate would be rare by CRFG standard. I agree there are meetings that feel too "normal".

Blueberries and pawpaw were rare because they didn't normally grow in places like San Diego. But these days with the antioxidant food popularity seems like every gardener in California is growing several blueberry bushes of some Southern Highbush or Rabbiteye varieties.

What I was told by a French grower is they need to be pollinated by a different genotype plant. So you need to use a plant grown from a different seed. Furthermore, The flower structure does not allow bees to do pollination, so you'll have to get to them in the morning before the bees steal all the pollen. The last point I remember is that the curvature of the pistil determine whether he pollinates a flower or picks it. Curve down means receptive and up means sterile.

The gentleman is able to set every fruit he pollinates and have deals to sell the fruits to a couple of local restaurants.
