Apple, Pawpaw, and Jujube care help

I have quite a bit of experience with a variety of wildlife trees over the year. My philosophy has been to provide a permaculture deer food source. This requires high volumes of trees. Because of the volume of trees I wanted, I grew many of them from seeds and nuts in rootmakers over the years. I've also done grafting of persimmons and apples with success. Also because of the volume, I started with trees that produce and require near-zero care after planting. Therefore apples were last on my list. They would be only disease resistant varieties and get no pruning or fertilization or anything as part of my QDM program. Of course, they produce very little with this approach which what I expected for many years. With a full QDM program, there simply is not enough time to provide care to this high volume of trees. I started with bark grafting existing male persimmons over to female which, by far, has been my biggest bang for the buck. We have planted pears. They were sold as Kieffer, but I doubt that is what they actually are. They were planted by my partners. We only have a few. They produce heavily but the pears are all eaten by the time our season starts. I grew hundreds of chestnuts from seeds from Dunstan trees. I've also propagated Allegheny Chinquapins as they grow natively on our land.

Well, I'm pretty much retired now. A few years back I planted a handful of trees at our retirement property. They are primarily for wildlife, but there are few enough of them (and we live there), to actually take care of them properly. So, while I have lots of experience growing and planting trees, I have almost none with tree care.

At the retirement property we have a few apples, pawpaws, and jujube trees and hope to plant a few chestnuts and ACs later this spring. I watched a few videos on pruning apples. Mine, were in bad shape, never being pruned. There were many lower branches and multiple branches coming from the root system. I'm not even sure which were actually my M111 root stock and which were the grafted variety. I pruned them heavily, to hopefully get them in the right direction. They are probably well over 5 years old, but still very small because of no care. They are caged.

I'd like to fertilize them. I have a bunch of 10-10-10 available. My hope is to spray gly (when the wind stops) to kill vegetation within about 6' of them, throw down the fertilizer, and cover it with mulch in the next week.

How much 10-10-10 per inch diameter of the tree would you use? They have never been fertilized before. Because they are heavily pruned, I'd like to encourage vegetative growth at this point to make sure they recover. I'm not worried about fruit yet.

I also have a few pawpaw trees. They were rootmaker trees grown from seed and are probably close to 10 years old but have never produced fruit. They were probably 2' - 3' when they were planted but are only 4' - 7' now. They have never been pruned or fertilized.

Should I prune them. I'd like to remove lower branches, a few each year, so that I can eventually mow around them. Most are caged but one is not. Deer don't seem to bother it at all. How about fertilizer?

I also have a couple tigertooth jujube trees. They are not grafted, grown on their own roots. I purchased some bare root trees and planted them at the farm years ago. Jujubes tend to propagate from the root system. I dug up some suckers with enough roots and grew them in rootmakers and eventually planted them at the retirement property. They took off like gang busters. They have not produced fruit yet, but should soon.

Any thoughts on pruning or fertilization amounts? I do want to start pruning lower branches soon so I can eventually mow under them down the road. They were the most recent tree I planted but they are by far the tallest. I'd say they are about 15' tall right now.

Any thoughts or guidance would be helpful

Thanks,

Jack
 
Northerners have a big advantage over us Southerners in growing apples. Juniper rusts (including CAR) are far more severe in Zone 7 and below than they are up there. Fireblight seems to be more severe for us as well, and there are some Northern locations where Fireblight does not exist at all. The same goes for other apple maladies such as Scab, Powdery Mildew, Bitter Rot, etc.... However, years of experimenting has taught me that for us it is all about choosing the best disease resistant varieties. I have loads of good apples nearly every year without spraying, but it is always from the same good varieties. Topworking the bad ones is the way to go with those.
 
I've done zero pruning or fertilizing of my Tigertooth. Maybe I should, really don't know. It's grown well but fruit production has not been great. It's never sent up a sucker. Wish it would so I could get a few more growing.
 
If it was grown on it's own roots, you can also dig up a piece of root when dormant. I put the root cuttings in sand and watered them as needed over the winter outside. The following spring about 15% of the cutting put up top growth and began growing. In time, I transferred them to rootmakers. I got several trees this way. If they are grafted, you can't do this.

It took mine quite a few years to fruit at the farm. No care after planting. Once they began fruiting, they have been very consistent with good crops.
 
It's on its own roots. I was leary of the "wild" rootstock commonly used for jujube and how it's know to thicket. Planted in 2015. Hasn't produced more than a few fruits in a single yr yet. I figure it's not in it's ideal weather pattern here so I'll take what I can get, and hope with time it'll have some good seasons.
 
They are self-fertile, but I think having more than one tree helps. I had 6 of them. Three got hit with gly drift when young. Two of them were permanently stunted. They did not die but are basically still sticks with a few leaves. One got setback. It is not as big as the other three, but still pretty good and produces pretty well. The other 3 produce heavily every year. I watch turkey fly up to knock down fruit and then fight over it on the ground. I figured I was pushing it zone-wise as well but mine have been a success.
 
Here is one back in 2012 when first planted as bare root from Just Fruits and Exotics from Florida:

Here is the tree in 2017:

Here is a closer picture of the fruit in 2017:

Here is a root I dug up and cut into sections for propagation:

None of these were pruned or fertilized. I found I can't mow under them with the tractor because of the lower limbs. That is why I'm considering pruning lower limbs on the trees at the retirement property now while they are young.
 
The 2017 pic looks a lot like what mine looks like now. In the close-up pic with fruit there a hole in the fruit (top right of pic). This happens to most of my fruits. Do you know what caused it. Just Fruits and Exotics doesn't have them very often anymore. I should add a tree just because.
 
I think it was either birds or bugs if you are talking about that one non-ripe fruit in the upper right of the picture. I believe that picture was taken the first year they fruited. Mine are at the farm for wildlife, so I don't pay much attention to the fruit except for volume.
 
I decided to wing it. Here is what I did so far. First, I probably over pruned the apples. They were a mess with no maintenance since planting. In some cases I had second and third leaders coming from the same roots. I could not tell which were below and above the graft. In some cases, it was obvious that one was my M111 rootstock and the other the grafted variety, but I was not sure which was which. In those cases I left two central leaders. Since I pruned them back so hard, I figured it would not hurt to leave the extra one for this season. I'll figure out which was which and mark them later this spring. Next year, I'll remove any of the M111 top growth.

Next were pawpaws and Jujube. In both cases, I decided to prune the lower 1/3 or so of the branches. The pawpaws were well formed. Not so much with the Jujube. They had second leaders competing with the main leader. I pruned them back to one leader and then remove about 1/3 of the lower limbs. I hope to remove more dormant limbs after this growing season if they do well.

Next I started fertilizing and mulching. Lowes had mulch on sale for less than I could buy it in bulk picking it up myself with a dump trailer. They load it in my truck for free, so I couldn't beat that.

Today I finish 1 apple, all 4 pawpaws, and both Jujube trees. I sprayed the area for about 6' around trees yesterday with gly. Today, we mechanically removed grasses and the cages. I fertilized with 10-10-10 at about 1 lb per inch of trunk diameter around the drip line. We then mulched them and watered them. For the apple, I replaced the cage. The deer don't seem to bother the pawpaw or jujube and the central leaders are well out of reach, so I did not replace those cages.

We have 4 apples left to finish this weekend. I probably have about 6 spots where trees I planted died and were removed. If the Chestnut approach I'm taking this year works, I'll plant chestnuts in those spots and reuse the cages.
 
Did some research this week and apparently jujube trees need to be pruned differently than apples and pears. They don't respond to cuts the same as other fruit trees. 1 cut stops growth, 2 cuts promotes.
 
Based on that input, I did a bit more pruning on the Jujube. Not much but I tried to give them a bit more shape. The next month or so will tell. They are fairly late to green up.
