I like your post Shedder showing your apple trees hiding among the timber. Wild AND free apples are a major boost to this property. Your post adds to this thread substantially; hopefully other people will say hey maybe I have apples I hadn't noticed. After releasing over 2,000 apple trees on this property one would think I knew where every tree was. With logging over the last three years I would mark ahead of the loggers all apple trees so they could avoid them; You wouldn't believe how many I found that I had never noticed before.
All of the apples in your pictures look to be great candidates for release. Regarding the one that fell down and has multiple stems;it will no doubt need thinning someday. For now though I would consider leaving it be un-pruned until the stems start to hold each other back; then the weakest can be cut of course to allow the strongest more light and nutrients. As you know but others may not realize the apple tree browse is very important to our cold climate deer. If that multiple stemmed tree is in a special spot I might even tube or fence the better stems now.
The tree not producing apples is interesting. I am a wholesale apple tree releaser (releaser not a word but you guys likely know what I mean) so my technical knowledge is only self-taught but here are my unscientific thoughts on it. If it has blossoms and no apples then it either isn't being pollinated or is pod sterile. If there are no other apple trees in the area compatible to the subject tree not being pollinated is possible. Documenting the flower time and planting a crab apple known to flower at that time could do it. Also the tree could be tested for its ability to create apples by you pollinating test blossoms yourself. I'll go over that in a separate post when time permits in time for blossom time.
Thank you for pointing out the book by Poulan. A sample read on his website was very interesting—ordered the book from Amazon this morning. I enjoy reading everything that touches on old apple trees and truly appreciate the reference to it.
It is interesting how your spruce trees and alders are so prolific in your area. Other than what I have planted here there are two ¼ acre stands of spruce and a lone young plant here and there. I saw what you describe regarding spruce in Northern Maine; paths used to get to the best fishing holes would constantly fill in with young spruce. Alders there grew along seemingly every slow drainage and many of its creeks. Here there is only a few alder stands along the drainage's and one field is developing a nice alder stand as well. So yes our properties are very different except for the presence of wild apples.
If your friend doing the wet apple tree propagation would like scions from trees practically growing in water I can provide them in the interest of helping his study. I know of some trees that produce apples that are located in water areas such as he describes. Scions from those could be collected this year. In addition I could check more of my trees that are mostly growing in/near/almost underwater to see which produce apples and then provide scions the year after.
I use 50 lbs as the minimum projected average crop of apples per released tree; it is random low ball guess but it gives me a reason to keep seeking out more trees to release.Some trees produce hundreds of lbs for sure. At 50 lbs. per released tree times 2,000 trees provides 100,000 lbs of food to the wildlife living here most every year.. It is all free except for labor. Its not for everyone but anyone in apple country can see the possibilities are well worth the effort. This does not include the huge amount of browse the deer eat produced by the wild apple trees.
Looking at a small section of one side of this tree it is not a stretch to estimate a few hundred pound of apples are on it so an average of fifty may be very low. I have not been able to find any scientific studies showing the average weight of wild apples produced per tree.
