Growing Mango trees in Southern California

<< < (145/146) > >>

Victoria Ave:
Hey all, had some time this morning to take care of my trees so thought Iíd post an update on my yard




California native plants as ground cover between my mangos on the shady side of the house. Now that days are longer these trees are getting about 4-5 hours of direct sun on the NE corner of my house and liking it.

 




Manga espada seedling. This seems quite vigorous, was multi branched when I got it and at each terminal node is consistently puts out about 5 to seven shoots which I have been nipping back to 3. No cold damage at all and started flushing before any of my other trees. Put out a few small blooms but nothing took. May graft a limb or two as there seems plenty to spare. Would like to try the fruit off of this and grow for rootstock.







Mallika flowering like crazy. This one took the most cold damage out of my trees. Had three nights of around 32į F weather and I covered and put Christmas lights on after I noticed all the leaf tips on the plant crisped up. Has flowered early and strongly, lots of female flowers. As tempted as I am to let fruit form Iím going to snip all off once night weather gets warmer. Thinking about snipping the central leader off and going with and open vase shape from the three scaffold branches, but it seems a waste of all that growth. Thoughts?







Valencia pride bark graft is growing strongly on my chopped root stock. Graft was my first graft attempt and 1 out of three scions took. The light green leaves are fresh growth from this scion. I have three good scaffold branches that have developed for me to try grafting onto again when June rolls around. I already have a list of varieties I want to graft. And it greatly out numbers my trees to graft on to. I think I will limit this trees to three varieties max.

 





My scraggly looking 7í tall Valencia pride. Last year was first year it started growing vegetive growth well with about three flushes. Some areas gaining about a foot or more. It held one fruit to maturity, but I believe that was my fault for not irrigating enough during fruit set as it held a fruit from a late cold snap after I set up automatic irrigation and got regular on it. Tree has flowered well and lots of little fruitlets, but the ratio of female flowers is no where near as high as on My Mallika. Last week it reached day time temps of 100į F. This whole week night temps have been down into the 40įs maybe Iíll get another bloom set.

On the flowers shown am I seeing powdery mildew? I didnít want to jump the gun and start spraying like crazy so the past couple mornings I have hosed the tree down well and today I snipped all the flowers like this off (just portions not the whole panicle).

Was thinking about grafting a couple branches that donít hold fruit this year (really hoping for a good fruit set!) with Val-Carrie as this sounds. Like it would be a fun combo. Hoping my seedling grafted with VP will grow much more vigorously than this tree which has maintained the same size since I bought it from a nursery straight from Florida.

Victoria Ave, great updates on your trees. Your trees are looking happy and healthy. If any of your branches start getting droopy from the weight of the blooms, you can remove about half the bloom panicle to relief the weight. Just donít remove the entire bloom until it gets much warmer- average nightly lows above 62F.

Iím glad you are also planting some seedlings. Plant as many different varieties of seedlings as you can. The greater the genetic diversity, the better your odds of finding a rootstock that thrives in your specific soil and microclimate.

I highly, highly recommend this technique to everyone attempting to grow mango in SoCal. You will be shocked at the growth rate of some seedling trees but the secret sauce is to get a hold of as many different varieties of seeds as you can, both Monoembryonic and Polyembryonic. Iíve found that seedlings from my mango fruit and fruit given to me by friends to just take off like a rocket.

Generally you have about 3-4 years of vegetative growth before your seedling tree will bloom and if you can maximize growth by fertilizing during the hottest months of those 3 years, you should be able to form a great foundation of scaffold branches to graft onto in the future.

You may be interested in varieties like Sweet Tart, Ceci love, Peach Cobbler, Pineapple Pleasure, Lemon Zest, Orange Sherbet, Kathy, Venus, E4, M4 and O-15.

Based on observations at my location, the 0-15 Mango appears to be a good grower. I am optimistic about this tree as I just planted it in the ground in 2021 and it grew well in our cooler summer that year. The 0-15 was grafted onto a manila seedling and as you can see from the photo is doing well.

As Simon has mentioned there is great variation in the growth and vigor of various mango seedlings. Some are excellent and grow robustly while others are weak and lack vigor. Having a strong mango rootstock is key for long-term success.

Also regarding Lemon Zest in SoCal here are some observations about growth. I have two grafted LZ mango trees, one at my coastal location and another in inland Alhambra just south of Pasadena. Both trees were grafted onto Ataulfo rootstock and both are good rootstock. I have noticed better and faster growth at the Alhambra location which is 15-20 degrees warmer in the summer. The Lemon Zest appears to thrive more with increased inland heat.

My advice: don't graft on any seedlings until they are over 8 ft with trunk bigger than 2.5". Graft too early will stop growing and end up with droopy trees regardless seedling variety. The graft will spend most energy in making flowers and fruits.

I second sapote, scions grafted to small 2-3 year old seedlings will droop no matter what seedling variety is used. People posting pic of seedlings with 2.5" trunk are at least 8 years old or older here in SoCal.
