Tropical Fruit Discussion / Alano Sapodilla Fruit set
« on: September 12, 2023, 03:12:25 PM »
This year, my alano sapodilla has thousand of flowers but no fruit set.  All the buds seems to be drying and dying off.  Is there a way to improve the fruit set?  I give it extra water & fertilizer this year.  Does it need to be cross-pollinated?  Location zone 10a/b.

Citrus General Discussion / sign of citrus greening
« on: June 03, 2022, 11:58:18 AM »
Location is san diego out of the quarantine area.  However, I'm seeing signs on my trees that I think could be citrus greening (huang long bin).  These trees were healthy as recent as 2 months ago with full of little fruits.  I fed them with micronutrients in late February so I think it is not a micronutrients deficiency.  But I left town for 9 days 6 weeks ago and when I came back it deteriorated.  Below are some pictures.  I have contacted CDFA and they will have someone calli me next week to check.  I'm dreading this.  Two of the trees in the photos are sumo and one is a multigrafted.  Do they look like citrus greening?

Tropical Fruit Buy, Sell & Trade / selling my glenn mango tree
« on: December 22, 2020, 03:46:03 PM »
Update: SOLD

I bought this glenn mango tree from Champa nursery about 2 years ago.  I'm selling it for $90 terra cotta pot included.  I've been growing it in this terra cotta pot since.  This pot is about the size of a 10 gallon nursery pot.  Need to downsize because I have too many trees in my yard.  The terra cotta pot is included in the price.  If you don't want the terra cotta pot, then after you plant the tree in the ground and return the terra cotta pot to me, I will refund $15.  The tree has fruited this year.  It was carrying about 3 fruits the size of a satsuma mandarin when the branch carrying the 3 fruits just broke.   Located in San Diego area.  Pick up only.

« on: July 14, 2020, 01:18:37 AM »
Typically large trees at nursery are put in these trapezoid box 24" or 36" wide at the top and smaller at the bottom?  Does anyone know why these type of box are  used?   Does it help with the root of the tree?

« on: March 25, 2020, 12:43:49 PM »

Citrus General Discussion / grafting scion from CCCP
« on: March 05, 2020, 11:56:52 AM »
Yesterday I received the scion from CCCP.  I ordered Xie Shan, USDA 88-2, and Boukhobza.  I used mostly T-bud on my Carizzo rootstock in a pot.  Very easy to lift the bark this time of the year.   I did a couple of cleft grafts but the budwood is too small so I don't think they will take.  So after budding and wrapped with buddy tape, do I need to cover the graft union with alumninum foil and keep it under shade?

Citrus General Discussion / lemon foliage drop
« on: February 19, 2020, 12:43:25 PM »
Hi all..

My eureka lemon tree leaves is yellowing and dropping too much at this time of the year. I also see quite a few flowerss on it.  Is this tree stressed because of too many flowers or lack of feeding?  The last time I fed it was on February 1st with an organic fert of 6-6-5.  I have some pics attached.

Citrus General Discussion / New citrus variety: Banzzai
« on: February 05, 2020, 10:48:43 PM »
Has anyone been able to taste this yet?  It's only available in Spain so far.  Look like a Shiranui.

Four wind growers are selling citrus rootstock for $4 a tree in a 1 gallon pot.  See links below.  The minimum purchase is 8.  I don't need that much.   Anyone in the san diego area want to chip in with me to get to the minimum 8?   I will cover the shipping cost if there is any.


Citrus General Discussion / Tango mandarin stunted after re-pot
« on: December 07, 2019, 11:37:20 AM »
I bought a Tango mandarin from four winds grower in middle of October.  The plant potting mix was a mixture of fir bark and peat moss.  So I decided to bare root the tree and repot it in a more gritty mix and still well drained.  I re-potted it on 10/14/2019.  I also gave it a scoop of osmocote plus.  I leave it in the shade for two weeks.  After two weeks, I brought it out to full sun.  Since then, the plant has been stunted.  The new growth/leaves are yellow.  The old ones are turning yellow also.  Do you think this is a seasonal issue or lack of nutrients?


Citrus General Discussion / soil test report
« on: November 13, 2019, 02:39:10 PM »
I finally dug a sample of soil from my trees and send it in for  a soil report.  The report came back.  According to the report, the soil is extremely low in nitrogen and high in sulfur.  pH is relatively high at 6.9.  I fertilize every two months.  Since the report, I used blood meal as nitrogen.  Is the cause of the problem is due to iron deficiency?  which is better for iron deficiency?  chelated iron or soil acidifier with iron?  thanks

Hi all..

My gold nugget has been struggling ever since transplanted in May.  It was ravaged by bug and aphids in the summer and finally look to recover.  Now the leaves are all yellow even the young one.  From the photos, do they suffer from lack of micronutrients or just nitrogen?


Tropical Fruit Discussion / Ragged looking Sir Prize
« on: October 16, 2019, 12:50:06 PM »
My sir prize was transplanted in March 2019 from a 15 gallon pot.  It already flowered and vigorous looking when transplanted.  I removed all but 2 of the fruits when they set.  Now the tree is looking really sick and ragged.  I'm guessing it is due to bearing fruit too early.  People told me not to let it fruit during the first year.  From the photos do you guys think the trees with all the leaves turned yellow and burnt at the the edges is a seasonal thing or due to carrrying fruit too early?

Tropical Fruit Discussion / Chloride tip burn on avocado
« on: September 05, 2019, 11:56:20 AM »

It's only september and my Sir Prize (transplanted in march) is already showing sign of tip burn.  I've  been irrigating frequently for the month of august.   Below are the pictures  of the leaves that have chloride burn at the tip. For the month of August, I watered 3 days a week for a total of 36 gallons of water for this tree.  Anyone have any suggestion for leaching this tree?  I've been searching on the forum for leaching but couldn't find anything.
