Tropical Fruit Discussion / Conserving graywater for fruit trees
« on: March 17, 2015, 03:59:01 PM »
California is in drought... and heatwave... My R/O water filter is not generating enough waste water right now to cover the whole garden, and I'm looking at sources of graywater before turning on the water faucet. For example, we easily collect 2 buckets of water in the kitchen daily, if we pay attention.

Does anyone use water from the shower or washing machine? How? Thanks a lot!

For those of you mighty gardeners who squeeze maximum amount of fruit trees into limited space... I am very curious what do you consider a reasonable minimum spacing for your tropical trees.

I know in Dave Wilson's Backyard Orchard Culture theory, trees could be spaced 3 feet apart in hedgerow planting, is it realistic when it comes to tropical trees? What distance do you use for your trees and what factors do you consider? (I am planning 4-5 feet distance for loquat, cherimoya, fig, wax apple, but my parents feel it's way to little. The yard space in question is only 5' deep though instead of 10' compared to the hedgerow diagram below.)

When it comes to pruning, I heard it involves topping the trees frequently, at least for some non-dwarf varieties (cough cough kohala longan). That is, I do not want large trees, but if heavy pruning makes them barely fruitful then it defeats the purpose of planting fruit trees. Any tips and tricks to minimize the negative impact on the tree's productivity? (To be very honest, I researched on "summer pruning" and still very clueless when is it in SoCal and how is it done?)

I am trying to figure out if anything can be done to bring more light to the base of my north facing wall. I heard about mirror, mylar, and even solar panels!! Thoughts? Experiences? Concerns? Thanks a lot!  :)

Tropical Fruit Discussion / Size & type of containers for fruit trees?
« on: March 09, 2015, 02:33:54 PM »
I maxed out of the full sun and even the part shade yard space, at least according to the opinion of my mom, the boss.
But my wish list is still long and ever increasing! For all of you who grow fruit trees in containers, what size and type of containers do you use?

My containers would sit on concrete, saucer advisable? Not planning to move them often after settled, once a year at most. May plant them in the ground later to replace other trees, so a nursery pot would be easier to transplant from? I cannot decide between 25 gal and 15 gal, the bigger the better but those pots are harder to handle / come by...

Trees I have in mind for containers: pakistan or white mulberry, pickering mango, dragon fruits, papaya, more loquat & avocado... Pierce cherimoya lucks out and will have a spot in the ground.

Temperate Fruit Discussion / Acidify soil for blueberry?
« on: March 07, 2015, 01:19:51 PM »
While I was away, my "Bountiful Blue" blueberry in full bloom suffered a period of total drought due to neglect. Fortunately it survived, but the new leaves are kind of reddish.

OK, I should not blame the reddish color on the drought, the plant was always like it after moving in. If my cheapo test is to be trusted, the soil pH is above 7. I have wanted to acidify / improve the soil. Bought one lb of ferrous sulfate powder 2 years ago but never figured out what amount to use. There are no instructions on the bag, internet sources are more like commercial application. Any one has experience working with ferrous sulfate?

I also consider mulching the pot with some pine needles. Will it help at all? Many thanks!!

2 years ago...

now  :'( :'( :'(

looks like I'll soon get a few trees from local nursery - longan, lychee, mulberry and possibly wax apple. I'm torn to decide how to squeeze all of them into my yard, along with loquat tree in container.

south side of the yard has much more room, but neighbor's house and existing trees cause part shade. north side of the yard is full sun, much narrower strip with limited space, apple tree may have to go to make some more room...

do any of these trees fare and fruit reasonably well in part shade? (loquat?) thank you very much in advance!

Citrus General Discussion / Help... scales on orange fruits
« on: March 03, 2015, 03:26:18 PM »
Orange fruits got quite some pest eggs scales on them. Any organic treatments out there? Many thanks!

Not sure if part of the reason is because the tree needs major thinning / pruning, the canopy is so thick that I have a hard time picking the fruits...

Tropical Fruit Discussion / Whitewash avocado tree to avoid sunburn?
« on: February 26, 2015, 02:32:41 PM »
So yeah, avocado tree got trimmed down to ground (tears) except one branch with minimal foliage. I have read it's crucial to protect the trunk from sunburn by painting it with diluted water-based interior latex paint.

Do you paint all exposed trunk and major branches? The tree trimming company told me they don't bother, but if wanted, paint the sides of stump and leave the top. Would the freshly cut stump top and lone major branch be susceptible to sunburn as well?

Alternatively, is there any drawback to this whitewash method? Frost cloth anyone? Thank you very much in advance!

I have a 4' tall persimmon tree planted at an absolutely wrong spot. I would like to dig it out and move to a sunnier spot in the yard, is it better to do it when fully dormant (it has zero leaves right now just like my very fruitful jujube tree), or later in the year when it hopefully has some leaves? This poor thing is barely hanging on, I doubt it grew any for the past 2 years in the ground... Many thanks!!!

(sorry Mod, just realized persimmon is not a tropical tree, oops)

Edited to add: sorry for not doing my homework well, dug more on Google and learned fully dormant is better.

In Southern California, San Gabriel Valley area, PM if interested. Easy to grow, fruit tastes great and is quite a grand sight when flowering. Cuttings are sitting on the ground now. Take as much as you could. If you see this listing, it's available!

Tropical Fruit Discussion / ID help: is this Fuerte Avocado?
« on: February 22, 2015, 02:32:30 PM »
Hello I have this beloved avocado tree in my backyard, and have been wondering what variety it is! From Google searches it seems closet to Fuerte? SoCal zone 10b. Your help is greatly appreciated!

This tree is soon to be trimmed significantly (see here). Hopefully I'll have new woods coming out soon and scion wood to give away :)

Tropical Fruit Discussion / Trimming overgrown avocado tree then graft?
« on: February 20, 2015, 04:46:00 PM »
Dear tropical fruit forum community, I am hoping to hear some advice as I am total new to gardening and this avocado tree is too precious to us. It's 25' tall with grafted variety on right side and rootstock on left side. We are contemplating to trim the tree down to more manageable size, the questions are:

1) In SoCal zone 10b, how risky is topping? It may involve 4-5' topping on the main rootstock branch (#2). We want to find the balance between easier picking and long-term damage. Minimal yield for couple years is expected.

2) The rootstock side may completely lose a major branch (#4), cut at approximately 5 feet from the ground, roughly 1 feet diameter. How realistic is it to graft a piece of scion from the "good side" to here? Grafting tutorials seem to talk about significantly smaller bark diameter (within 1/2 feet). Is it too much for the tree's health to trim and immediately graft?

3) There is a lot of weight on the good side branch, what would you recommend for a good support? Maybe put a 4x4 wood underneath?

Your help is greatly appreciated!

Edited to add photos of trunk damage :'(
