Just wanted to bump this thread in case anyone happens to have or know of a source of Passiflora popenovii.  If you are in Colombia or Ecuador, could you message me?

Thanks!

I'm looking for 2-3 lucuma seeds for a public garden I'm planting in Albany, California.  Let me know if you have some -- thanks!

I was at a friend's house this weekend when I noticed her avocado tree:

I was very intrigued, and was preparing to offer her all sorts of vegetable trades, when she disappointed me by telling me that it has never fruited in the 10 years since she's lived here. The tree was already here when she moved in, so she doesn't know the variety or age.

The tree looks reasonably healthy, and it's flowering right now. It's about 14' from ground to the tip.

What are the most common reasons that an avocado tree won't fruit?

This area is definitely avocado-friendly, as I have two neighbors about 1/2 mile from each other that both have heavy bearing trees.

This friend is a 3 mile crow flight from those other two trees, but it's a very similar climate.

If it's a seedling (i.e., ungrafted) tree, that's not too surprising.  A lot of seedling avocado trees in Northern California are huge and don't produce much or at all, and there are others that do produce a ton of bad tasting fruit.  You might prune back the tree and graft new shoots with named varieties.

I'm also curious -- where in England are you able to fruit Avocados?

Thanks!

I have a bunch of random seedlings and it’s too early to say for sure but they all seem to grow as well as the Lavern Manilla Mango seedlings.

Interesting.  What do you think it is about the Turpentine seedlings they use in Florida that makes them particularly bad for California?  I ask because if so many different seedlings can work for us, but Turpentine doesn't, there must be something about it that makes it uniquely bad for us and good in Florida.

Chrysophyllum oliviforme is edible; not palatable.
Now, they became a tree weed in Kerala.
We use the species as rootstock for Star apple.

Thanks.  Given that it is less tropical than Starapple, I'm curious: what about it makes good rootstock for you, since your location is very tropical?  That is, why not just grow Starapple on its own roots?

Anyone in a subtropical area growing C. oliviforme -- how does it grow for you?

I'm curious -- which mycorrhizae did you use / from what source?

I did a little experiment using mycorrhizae.

Without mycorrhizae



With mycorrhizae




Both were planted as seedlings... prior to planting them the photo ofnthe top was acutally bigger after a few months the one with mycorrhizae is way bigger than the one without.. i dont believe its a waste to add mycelium in the soil.

Oscar, I'm really interested to find out how the Chucte fruit ended up tasting.  (If it has ripened.)

I guess you didn't see this? http://tropicalfruitforum.com/index.php?topic=4481.msg290725#msg290725
Ate lots of them. They are very rich in oil, between 25 and 28%, compared to between 7 and 21% for avocados. The taste is very nice. Main problem is they go bad really fast once ripe, don't keep as well as avos.

Oops, sorry I missed it!  That sounds great.  Was the flavor avocado-onion like or avocado-coconut like?  (Those were the two flavors that were described in the Jay Bost research papers.)

Yeah the scions are very durable. Raul did a good job. I don't know of anyone else selling the scions so we are all very lucky to have this resource.

Still, I'm wondering when to remove the tape? It's essentially buddy tape. I'm just worried that the scion will rot underneath if it's turning black but the top is still green. Anyone have advice on this?

Generally I think buddy tape / parafilm just needs to be exposed to some direct sunlight and it will degrade on its own.

Hello,

I have Orange, Lemon, Lime, Avacado and Mango trees. Found online some fertilizer which works for all of them (i.e.SUNNILAND CITRUS, MANGO AND AVOCADO FERTILIZER). Wondering if anyone has any feedback for it or other suggestion for organic fertilizer for my trees?

Avacado and Mango trees are 2-3 ft tall and just planted this year. Citrus trees are full grown trees.

TIA

The thing I learned (indirectly) from Gene Lester, who is the Northern CA citrus expert is to use Rhododendron / Azalea fertilizer -- never use "Citrus" or "Avocado" fertilizer.  Soils in our region tend to need the acidifying effect of Rhododendron / Azalea fertilizer.  Coffee grounds in massive quantities are also a good option.  So I use either for all subtropicals and tropicals I grow.  No idea if it's ideal for Mangos, but around here Mangos grow so slowly I never try to push them with heavy fertilizer.

I got surprisingly good results from Raul's scions.  I grafted four of them on Achacha rootstock and all four took but one died after pushing.  I also grafted two more on bacupari miudo (G. brasiliensis) rootstock and got one take and one that hasn't died or pushed.  I think one thing that helped was that I had all of them in the shade in a warm indoor environment, with their water trays filled with water at all times.

That surprised me, because the scions survived a month-long journey.  I wish avocado scions would last as long (they sometimes go bad in less than a week).

Looks great!  Two quick questions:

1. How does it compare to Inga spectabilis in size and in amount of pulp (if you have that species as well)?

2. Are the seeds of all Inga species edible when cooked, and do they all taste about the same?  Or is this one particularly good?

Spectabilis pods get bigger than that shown in the photo of xalapensis. Almost all species of ingas the seeds are NOT edible. I think the exception to that rules is only 4-5 species  of ingas(out of 250+ species). Many ingas contain both green and black seeds, depending on stage of maturity, so that is not any indicator as to whether the seeds are edible or not.

Interesting.  I can't find any references online about Inga xalapensis being edible.  Oscar, do you grow any Ingas that have edible seeds?  It's surprising that there are a few that are edible; that kind of means to me that there are a few that are barely edible but most aren't.  Is that a reasonable way of looking at it?
