Citrus General Discussion / branch die off
« on: April 29, 2020, 10:38:47 PM »
I noticed recently the branch at the top of the canopy on moro orange started to die off.  This is after a foliage growth at the bottom and middle of the tree.  Anyone has any idea?

Citrus General Discussion / t-budding update from cccp scion
« on: March 25, 2020, 12:43:49 PM »
So I did some t-budding onto a carrizo exactly 3 weeks ago.   I remove the grafting tape this morning.  I'm not sure the t-bud take or not.  Can anyone take a look at let me know which one takes?

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.

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?

Thanks

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?

Citrus Buy, Sell, & Trade / citrus grafter needed in San Diego
« on: September 26, 2019, 05:18:46 PM »
I'm thinking of ordering some budwood from CCCP.  I have never grafted before.  Anyone in the San Diego area interested doing the grafting for me?  I can order a couple of budwood of your choice for you free of charge.

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.

Citrus General Discussion / removing water sprout growth
« on: August 03, 2019, 01:51:28 PM »
A couple of my citrus tree (moro and gold nugget) had been under stress due to overwatered, leaf miner etc.  So there has been almost no new flush of growth off  the main branch.  Instead, I saw most of the growth are on these water sprouts that are on the lowered part of the trunk.  See attached pictures.  Should I just remove them from the trees?  Thanks

Citrus General Discussion / Gold Nugget curling and pale leaves
« on: July 01, 2019, 10:00:27 PM »
I just planted my golden nugget 2 months ago.  Since then, there hasn't been any new growth.  The new growth that was there when I bought from the nursery is really struggling due to leaf miner.  (Just spray some spinosad a week ago. The owner of the nursery said don't fertilize for 2 months.  So yesterday I use half a cup of citrus & avocado gro-power on it.  From the pictures, can anybody tell me the macro or micro deficiency is?  Or is it a root problem?  I used the moisture meter to check if it is under-watered and reading is still moist.  Any advice is appreciated.

Tropical Fruit Discussion / yellow leaf spot on sapodilla leaves
« on: June 08, 2019, 12:19:09 PM »
I finally saw some new growth on my sapodilla tree that was planted in the ground 3 months ago.  On some new leaf, I saw yellow leaf spot.  Is this an indication of micro or macro deficiency?  See attached.

I'm deciding between these two fertilizers for my garden.  Anyone has any experience with these two?

Hi all,

I planted this eureka lemon on March 14.  Since then there has been flowers bloom and some are fruiting (I will cull the fruit soon)  but I notice at the bottom of the tree, the leaves are curling downward.  Is this a sign of nutrient deficiency?  What could this deficiency be?

Citrus General Discussion / Moro Blood Orange leaves turning yellow
« on: April 05, 2019, 11:08:37 PM »
Hi all..

First time posting in the citrus section here.
I bought this tree in late January and finally got around to planting it 3 weeks ago.  Right before planting it in the ground the leaves at the bottom are turning yellow.  After planting it, I think I over-watered the tree a bit.  Now there are more leaves turning yellow.   As from the pictures, the veins of the leave turn yellow first.  Is this a symptom of over-watered or nitrogen deficiency or iron deficiency?  What can I do to correct this problem?

Thank you.

Tropical Fruit Discussion / caring for young Alano Sapodilla
« on: March 26, 2019, 02:08:32 PM »
Last week I stopped by Champa in LA and pick up an Alano in a 7 gallons pot.  The container is quite light for a 7 gallon.  When I removed the container and plant it in the ground this weekend,  I realized the tree was covered in fir bark compost.  There was no soil or dirt.  So I managed to remove about half of the fir bark compost from the root ball and planted in the ground.  I'm in the San Diego area and it is starting to get warmer now.  What is the watering & fertilizer regiment for this plant?  It is about 2.5 feet tall right now?  I used a teaspoon of osmocote+ when I plant it in the ground.  Any advice would be appreciated.
