Tropical Fruit Discussion / Choice of a fruit tree / shrub on a slope in San Diego (PQ)
« on: April 08, 2024, 06:35:44 PM »
I live in PQ, and my backyard is a north-facing 2:1 granite slope with a little soil (DG + leaf litter) on top.  Old trees hold the soil from sliding down, so I can only replace them one by one.  One of the old trees blew over, so I have a spot near the rear fence to plant something.  I have a ton of plants in pots (species of Eugenia, Psidium, Annona; papaya, white sapote, persimmon, etc.). Which one would do best at that location?  It's somewhat protected when shorter than 6 ft, but exposed to the wind when taller than 6ft.  It never freezes here, at least so far. 
  • What fruit-tree is best suited for this location?
  • How thoroughly should I remove the (part rotten) roots of the old tree?  I was thinking of using what's left of it as a source of nutrients, but I never tried that before.  I can't really dig a hole through granite bedrock, I'm not a Hobbit.
  • What SoCal fruit trees are best able to hold on to the rocky slope with their roots, so they don't blow over?
   
Thanks in advance!!!

Tropical Fruit Discussion / best way to grow seedlings for sale?
« on: July 13, 2020, 12:09:57 AM »
Hi People.
I have a bumper crop of Billardiera cymosa in my backyard.  What's the best way to germinate and grow seedlings for sale, shipping within the continental US?   I can use regular 3" pots, or compostable 3" pots, or jiffy pucks (never used those before, but what the heck), or rapid rooter / root riot plugs.  What's the best way to grow seedlings for shipping within the continental US?  What is your preferred method? I have ample experience growing tropicals & subtropicals for myself, but I've never grown anything for sale; so please let me know.   Also,  I searched USDA website and found no restrictions on shipping Billardiera -- or did I miss something?   Please let me know.   Thanks in advance!

I’m looking for lucuma seeds (Pouteria lucuma) in US only - no shipping from abroad.   Preferably a “moist” fruit variety, not the “dry” fruit one.   Please PM me if you have fresh Lucuma seeds for sale or know where to buy them in US.  Thanks in advance!  Dimitry.

Tropical Fruit Discussion / Spondias pinnata
« on: April 18, 2020, 11:37:03 PM »
I have a young Spondias pinnata (from Trade Winds Fruit seed I planted in January 2018) that needs to be repotted into a larger container.  What type of soil do they naturally prefer?  (Rich / poor, pH, etc.).  Also, should I feed it heavily or sparingly, and with what composition of fertilizer (NPK values, micronutrients)?  Please let me know.  Thanks in advance!  Dimitry

« on: May 16, 2019, 12:44:27 AM »
I have a seedling of Randia formosa I grew from seed.  Can it survive outside?   I'm in San Diego.  If anyone has successfully grown Randia formosa (a.k.a. Rosenbergiodendron formosum, blackberry jam fruit) outside in SoCal, please let me know the best ways to keep it alive and happy.  Thanks in advance!

Tropical Fruit Discussion / is Bourreria succulenta edible?
« on: February 08, 2019, 12:07:29 AM »
Is Bourreria succulenta edible?   Bircher&Bircher book lists it as "said to be edible", and a few websites list it as edible; but one of its names is "poisonberry" and it makes me not so sure.  Anyone knows whether it's edible?  Please let me know.  Thanks!

Tropical Fruit Discussion / Dovyalis hebecarpa leaf drop
« on: October 15, 2018, 12:12:17 AM »
I have a few Dovyalis seedlings, some in a greenhouse and some outdoors (it's San Diego).  They all seem fine except one D. hebecarpa, which seems unhappy about something.  It is growing, but it has bouts of leaf drop: some perfectly fine green leaves just fall off, and occasionally the tips of the new branches dry out and die.   I inspected it for any visible pests or anthracnosis-like wounds multiple times: there aren't any.  What is it unhappy about?  It's in a greenhouse.  Whatever it is, it doesn't seem very infectious, as the neighboring plants show no signs of it, and other Dovyalis seedlings seem fine.  It's more like it's just unhappy about something.  Any ideas?  Thanks in advance!
