Tropical Fruit Discussion / Avocado leaves damage and pest control
« on: June 23, 2024, 11:53:22 AM »
I have noticed that the young leaves of my avocado plants are blackening, and some older leaves are curling and rolling. When I unrolled those leaves, I found live worms inside. I also found two mosquito-like flies sitting on the leaves, which I caught and destroyed. I assume these flies are related to the worms and the rolling leaves, but I am unsure what is causing the young leaves to turn dark and die without showing rolling symptoms. Anyone experienced the same symptoms on your avocado plants/ trees? If so, what did you use to fix the problem?

#1 & #2: Young leaves turned black without rolling.
#3 pic: manually unrolled leaves about a week after killing worms inside while it was rolled.

One of my new Hass avocado plants started having limp leaves during the daytime even on cloudy, overcast days with no sunlight.  However, in the morning and evening, it becomes very lively and upright. This behavior started a few days ago, so I moved it away from the sprinkler system due to concerns about waterlogging. I checked the bottom of the pot and found it moist but not wet. I made more holes in the bottom of the pot for better aeration. The other two Hass plants of the same age from the same nursery are doing well. This one was the most vigorous of the three. Now, I've moved it to a dry area with no watering system and am monitoring it closely.
Has anyone experienced this kind of behavior in avocado plants?
  This is the limp state. All the young burgundy-colored leaves used to be always at least 45-50 degrees upright during daytime.

Tropical Fruit Discussion / What kind of fertilizer are you using?
« on: May 18, 2024, 08:14:43 PM »

I have a growing family of young avocado trees, ranging from 1.5 to 4 years old. What kind of fertilizer are you using for your avocados? I am considering using composted chicken manure.


This is a Hass avocado tree. Despite initially growing well, it unexpectedly regressed to a smaller size after flowering at an early age, and it has even lost a few branches on its own. However, my primary concern now is that something seems to be eating its leaves. Strangely, nearby Lamb Hass and Sir Prize trees remain unaffected by whatever is causing damage to the Hass leaves.

I heard about Neem oil and Spinosad. Has anyone have experience with these product? Which one is more effective?

Sir Prize

Lamb Hass

One of the TIME's 2023 best inventions!

Maybe some of you heard about this new avocado varieties before. I am very excited about this new variety. The development of this particular variety spanned an impressive 60 years, according to the FGS."

 "The “Luna UCR” — also known by its scientific name of BL516 — was developed by agricultural scientists at the University of California, Riverside. The patent for this flavorful, black-skinned avocado is still pending, but that hasn’t stopped the agricultural and culinary worlds from eagerly anticipating its arrival. After all, it’s been in development for over 60 years."

I have sent an email inquiry to the Vice Chancellor of UCR regarding the actual public (nursery) release date of the plant. I am hopeful for a prompt response.

I recently watched a YouTube video about Maluma avocado which is originated from South Africa, not the Malama variety from Hawaii. This variety is known for heavy fruiting and excellent taste, making it one I'd like to have. Is anyone currently growing this variety

I'm curious about which varieties of durian are thriving in Southern California. Is anyone currently cultivating them?


I'll be intrigued by the array of avocado varieties you cultivate in California.

Last year, I reached out to several nurseries in search of Russell avocados, yet surprisingly, many nurseries in LA or San Diego were unaware of this particular variety's existence.

Surprise me, please!

Tropical Fruit Discussion / Is Keit mango this big normally?
« on: September 09, 2023, 02:38:36 PM »

I bought two Keit mangoes from stores. Initially, I didn't know what kind of mango it was. It was just gigantic, and when I checked label it said Keit. It is so big that it wouldn't fit in a regular bowl.

I wonder if it will grow well in SoCal. Does anyone grow it in SoCal?


Please rank the favorite, must-have fruit trees to grow, and fruit trees you will grow even though it is not the favorite.

My List;

1. Avocado
2. Blue Berry
2. Cherry
4. Macadamia
( Blue Berry and Cherry are equally favored, and 1, 2, 4 are must-have fruit & nut)

5. Jack fruit
6. Mango
7. Fig
8. Grape/ Muscadine)
( 5-8 are trees that will be planted according to space availability)

9. Dragon fruit
10. Pomegranate
11. Persimmon
(9-11, I don't care that much but might plant in case there is space after other plants)

Tropical Fruit Discussion / Has anyone experieced with double grafting?
« on: August 16, 2023, 02:41:32 PM »
My young "improved pollock" grafted avocado is not doing well even after all kinds of care with fertilizer and careful watering regimen. It is from Florida, so initially, I thought it was due to different climate. It has been passed already 5 months. it should has some noticeable growth by now.  It has some new young leaves only after older established leaves fell off after brief sun exposure. I have kept it inside most of time since all other Florida born avocado has died after sun exposure. I started to use Grow light to give enough light for photosynthesis. It seem to be helpful very little.

Now I am thinking that maybe the rootstock is not compatible with grafted Improved pollock or the rootstock is too weak to support fast growth.

The solution can be double grafting using this method on the video.

Did anyone use this method before and was it successful?  If I want to do it to the rootstock to give it more energy to the graft, when would be the best time in SoCal?

Tropical Fruit Discussion / Can you ID this mango?
« on: August 11, 2023, 06:32:10 PM »

I bought this mango from a Mexican grocery store. I searched #3488 and came up with " XL:  Tommy, Haden, Kent, Palmer and any other red mangos"
It is huge and very delicious. If it grows well in Mexico, I assume it will grow well in SoCal too.
Mango experts, please tell me your opinion.

Tropical Fruit Discussion / How many people eat mango skin?
« on: August 08, 2023, 09:16:00 PM »
I sometimes eat a piece of mango skin attached to the flesh. And I was wondering how many people actually eat mango skin intentionally. Do you eat mango skin?

I found this benefit from eating skin: "Mango skin is edible and packed with nutrients like vitamins, fiber and antioxidants. Though it may offer health benefits, it has an unpleasant taste, may preserve pesticide residues and contains compounds that may cause allergic reactions. While eating mango skin is safe for most people, it's unnecessary."

Tropical Fruit Discussion / SoCal avocado tree problem
« on: July 23, 2023, 01:40:39 PM »
I was thinking to post this to avocado thread but I changed my mind since some area in U.S. municipal water system might not be the same as San Diego area.
My older avocado tree leaves are all like this. I am assuming it is caused by either salt or chlorine in tap water.
Can some expert confirm the cause of this leave burns, please?

My avocado tree leaves become curly or brown on the edge.
I don't know what is causing this problem.
Does anyone know what is causing the issues?

I'd like to have Sweet Stephany, Sweet Lorenzo, and Tamara. Does anyone know which nursery sells Sweet Stephany in the U.S?

I am planning to have a few mango variety in the future, and pondering which variety would be the best to have.
I heard good things about Valencia, Lemon Meringue, Carrie, but there are hundreds, if not thousands different varieties in the world so I'd like to hear from you about your favorite variety.


I am planning to buy a Green Gold avocado tree and contacted one seller but he didn't respond. I am wondering if anyone knows any nursery or seller who sells Green Gold avocado in SoCal area.

I bought a bag of avocado from Costco and I left in my room to ripe. After a few days they seemed ripe so I put them in refrigerator. When I ate two of them, which has pebbled skin ( I assume some kind of Haas variety) had unevenly ripened flesh. So I was able to eat only about a half of the flesh. Only those two pebbled skin avocado were not ripen evenly, and the others were beautifully ripen and delicious. I wonder if there is a specific variety known for this. Anyone?

I live in San Diego. I have a few young avocado tree such as Shawill, Pollock, and Wilson (just seedling at the moment). I know Hass, Reed and Pinkerton bear fruit heavily and consistently. Besides those, which avocado variety do you have that produce fruit heavily every year?
