For the benefit of our California growers I thought I would post a few phots of some mango trees showing various rootstock. The goal is to select robust rootstock to increase tree vigor. A healthy root system is a healthy tree. Our mango loving frends in Florida have no such problems but here in SoCal it is a issue because of our cool winter and spring tempatures.
The first (3) photos is a Selected Ataulfo seeding I started two years ago and is green house grown. I just took it out of the container to Up-Pot to a larger #15. As you can see from the root system is is very well developed. This tree is excellent rootstock for grafting.
The next photo is my grafted Orange Essence mango tree grafted to a strong ataulfo that I just moved to a larger #25 pot in Spring. Even after harvesting (6) OE scions from this tree in mid July it still is putting out a good flush now. This tree grows well at my location with no disease issues.
Next is my young Dot mango Tree. I just planted this in the ground in 2022 from a #7 pot and it just flushed. I did have some dieback in spring from this tree but I just cut out the die back limbs and it seems to be recovering well now.
Next up is my five year old Lemon Zest Mango Tree on Ataulfo rootstock. It is currenty starting a new growth flush. The rootstock is fine but the issue I have with this variety is the constant attack of Powerdy Mildew (PM) with this variety. For this reason I am in the process fo topworking this tree. Orange Sherbet thus far has no disease issues and is a attractive mango tree so it is a much better choice as is OE with even faster growth.
The last example is my 0-15 mango tree on manila rootstock. I grafted this in 2020 to a very small tree at the time and planted it in the ground in 2021. This seems to have grown well and just finished it's first flush. The rootstock is strong and long term I am optomistic. There are no disease issues at all.
Having strong mango rootstock and good draining soil gives you a fighting chance in the early years of growth.
