One of your choice is Carrie I would opt for Angie and Sweet tart. PM Behl he might have them available
Sweet Tart is definitely productive on Manilla rootstock. Simon
Behl please share with us the evidence you have that turpentine root stock will not do well in Ca.There are so many contributing factors that could be reason for decline so I am curious what evidence you have that pinpoints the problems to definitively prove it's the root stock and not just a plug for a way to sell your own trees. I think some growers on this forum from Palm springs have no issues with turpentine in desert clay soil. From my experience the biggest factors contributing to mango decline are:1. Planting the tree too deep in the soil. Mango trees like the feeder roots to be able to breathe and dry out frequently. Over the years I have learned this from noticing shortly after adding additional soil and mulch that they start to die back and decline. Once removing what was added the decline stops.2. Over watering. They definitely start declining after too much water.3. Over fertilizing and too salty of fertilizer. If you use the wrong fertilizer or too much fertilizer the roots become damaged and struggle to supply water to the tree. 4. High PH soil. If you do not correct the soil PH the tree will have troubles thriving and always show nutrient deficiencies. I have found that if you foliar feed on a regular schedule the trees thrive and never have nutrient deficiencies. For the most part I have all but stopped adding fertilizer to the soil and solely foliar feed for the trees nutrient needs. They almost always are putting out new growth and salt is no longer a problem.Dyna-grow Foliage Pro is what I use and contains very little salt. When it rains the roots get fed with the runoff from the leaves. This is enough for the roots and prevents root damage from salts. When I water I water slowly over a fairly long time, and then leave to dry out. Once the tree shows signs of drought stress then it's time to drip water again.I have both Manila from big box store here in Phoenix, and Fla mango trees and they both act about the same in the poor soil. The manila may have more vigor than some of my Fla varieties, but some Fla varieties like Peach cobbler grow like crazy.Really curious how you have concluded it's the rootstock and not the care, poor water quality, or variety specific.Also one thing to keep in mind is some varieties do well outside their normal climate, and some do not. For instance, most Asian varieties do not grow very fast in dry climate. Has nothing to do with the soil. I have both in ground and in pot. No difference in growth rates..nothing to do with root stock.
I'm not Behl but I can say that our cold winter temps, alkaline soil an the low humity are huge factors to phomopsis. Turpentine rootstock is a much weaker less vigorous rootstock than Manila therefore more susceptible to phomopsis. Turpentine us less vigorous and more opportunities for the pathogen Peter owner of park hill orchard has taken dozens of dead turpies to the plant pathology lab at uc riverside those are the results..,..please read behl's post and stop looking at the Vegan athlete and Shane O'Leary's videos

DavidI don't understand what answer you are looking for you gotta trust Simon and Behl....they know what they are talking about remember what happen with Adam.this is on my ataufo rootstock I had over 80 on a 2 year graft last seasonOne branch from my friends ataulfo 2 year graftfrom my mom's 2 year Manila rootstock look at the size of the 2" trunk nearly kill my tree... 22 ST
Squam256 and Dongeorgio may still be selling scions. Sweet Tart is extremely sweet when grown in California and harvested ripe. Once you get the hang of when to harvest it, you can ripen it less for more acid balance or let it get fully ripe for much less acidity and much more sweetness. Those people that are sensitive to overly sweet fruit may want to avoid this variety along with LZ and several other Zill varieties that are ultra sweet. DOT is also an excellent variety. Many Mango growers in SoCal have had success planting random mango seeds into the ground. These seedling trees are known to grow to huge proportions. When growing seedlings in the ground, do not graft them with mature scions until the seedling is fully established and in exponential growth phase. When grafted(mature scion) mango trees are grown in SoCal, many of them will flower within one year and continue to flower every year from then on. This issue can be avoided by simply holding off on grafting with mature scion wood until the tree is fruiting size. Simon
