Tropical Fruit Discussion / Re: Artocarpus collection and spacing
« Last post by Ulfr on Today at 06:48:02 PM »
You mentioned doing serious pruning. Pruning is apparently very effective with jacks but not sure about the others. With consistent pruning Oscar could those spacing be reduced?

My grafted jacks are planted high density and spaced 15-16ft. I am hoping this is doable long term, time will tell.

I guess you also have the problem that stuff grows more quickly there and so would require higher spacing.
Pruning is effective on all. The only question is, will you really do it consistently? Moxt people lax off after the trees get big, and then they get out of control.

I will (canít speak for op). I use the same spacing for mangoes currently and only have a half acre to play with. Doable at my spacing you reckon?

Ditto, I got mine yesterday as well.

For the two people I offered to share with, check your PM or PM me.
Lets get these grafted ASAP.

Raul, check your pm.

I would add a champajak.  I think that the Jakfruit is a lot easier to keep small than a marang or pedalai.  We are being way more vigilant now with artocarpus pruning than in the past.  Certainly the jak, champ, and champ/jak can be managed in a 25-30í spacing.  The marang is responding to the pruning and I am hoping I can keep it nicely shaped in a space that is 25í X 35í.  Pedalai is something else, it just seems to need room.  Itís a fun project!

Tropical Fruit Discussion / Re: The weeds love my mulch
« Last post by KarenRei on Today at 05:32:32 PM »
So, I'll tell you the reason you're getting all of these weeds: it's the "horse business" that you refer to.  I use horse manure extensively as a fertilizer on my land. It's great fertilizer, but it's jam-packed with weed seeds.  You weren't just dumping mulch on your plants; you were planting weeds as well.

As for control: I'm an IPM-type, not a pure-organic type. But I wouldn't even consider most herbicides right next to a tree unless I can guarantee that they're extremely selective between the weeds and the trees. You could use foliar systemic herbicides like glyphosphate, but I personally wouldn't want to take the risk.  If I'm seeing in the pictures right it's a mix of broadleaf trees and bananas?  A broadleaf-selective weed killer might work around the bananas but obviously would not be safe around your broadleaf trees.  I think your best option might be pre-emergent herbicides. They kill off seeds / sprouting seeds but have no effect on mature plants (like your trees).  So whatever you (fully) remove (pulling, smothering, burning, etc) won't come back.

In the future: anything that comes from horses, for use where weeds are a concern, you need to hot-compost it.  That is, compost it at a temperature hot enough to kill off all weed seeds in it (it also prevents transmission of nematodes and other soil pests).

Tropical Fruit Discussion / Re: cloning gels

The cannabis industry likes the $, so I don't think they care that much about some little poison. OF course for trees and other plants it's okay. Until they start to fruit it should vanish from the plant system. I would not use the hormone to clone vegetables for instance.

Someone seems to like the burning latex. Just don't spray Neem oil, they are sensitive to it, it will burn the plant at 1%.

If you use a peat-based potting mix, there is probably enough buffer capacity to allow you to water with high pH water for years without issue. For example, I've been using canal water (laced with loads of calcium carbonate) for years on plants in the same peat-based mix, but pH is still well below 7.

Yep, I originally mixed the grow medium to be ~1/3 peat-based.  I just finished pH measurements of the three trees.  They seem to be in the right ballpark: ~6-6.5 pH.  I think I can rule out the pH as a source of problems.

But it's worth noting that avocados don't make the best container specimens. They will probably do well initially, but once they max out the container with roots, they will start to decline a little. I haven't done a lot of container culture, but if this is your long term plan, my guess is that you're going to need to root prune periodically.

I'm certain you're dead on that Avocados and containers are a self-limiting combination.  I really have no way to lift the trees (or even drop them to the ground) at the size/weight they're at.  I can only do my best to limit their size and optimize what's possible.  I sure would like to see one of the trees hold a fruit through to maturity.  It seems like that should be possible, but perhaps I'm pushing the wrong rock up the wrong hill.  If folks agree it's not hurtful (and possibly helpful in the short-term), I"ll plan to hit the trees with a Foliar spray of the Urea (+ surfactant) and follow-up with regular fertilization (Osmocote+, the Lilly Miller Azalea Food, or similar.  I'll also hit the tree with an iron/Zinc foliar.
Thanks for all the advice.

Hi, I live in the Placer county water region.  I've been told that the water is actually quite good.  I just measured it at around a pH of 8.

Here's a report I found:
https://pcwa.net/assets/doc/services/water-quality/consumer-confidence-reports/colfax.pdf

There is chlorine, but they indicate that it's on the low end of the spectrum for bacterial control.
