Grow Stones and Maples   1 comment

Last year I did two trees as an experiment with the grow stones. Both trees were planted in 100 percent grow stones. I did a conifer that was ailing which would give me a visual indicator during the year if the increased air and drainage was worth the effort. I also did a group of five maples thru a disk with five holes to build a massive taper larger trident. I can say that while the conifer was actually improved and grew very well the trident while not suffering too badly did not thrive in my heat.

I planted the trees as they were in the growing pots about 14 inches tall. The trees wear about 3/4 inch across and were planted thru 1 1/4 inch holes drilled in a ceramic disk. The tree grew and managed to grow to about five feet tall which in itself is good, not good for what they should have done in a year around here. I should have had about nine feet of growth and a good increase in caliper.

All of the trees I planted into disks were left the height they were while they had been growing as single trees. The smaller ones I planted from the seeds the year before were about 10 inches tall. While the small ones did increase in size and layer at the disk intersection, I feel this was because the better and more moisture laden soil they grew in. They all grew in colanders so that part was equal as well.

This year the large group of five in individual holes will be planted into a much more humus rich soil mix. Based on trees grown in previous years, the trees should begin to fill the holes and layer off. I need each one to increase in girth by at least 50 percent to even touch each other and begin grafting. Should take about two more years to get to that point.

The most important part of this project is what was done for this year. Like the trees I did a decade ago, massive girth in the bottom third of the tree will only take place when the shoot emerges from the trunk low on the trunk. Let me explain. When a tree is expected to increase in size, sacrifice branches are used to achieve this. If a tree is 20 inches tall and the sacrifice is used from a bud that emerges from the trunk in the first inch above the soil, that shoot will increase the base of the trunk by a lot over a season. In fact this is a good way to improve reverse taper.

If a person is trying to achieve a large trunk and uses a shoot in the upper third of the trunk, all of the branches adjacent to the shoot will increase in size but the base of the trunk will hardly see any increase in size. Further, all increase in size happens below a sacrifice or adjacent to it. For this project on the large tree as well as the smaller projects I have going, I have cut back all the trunks on the groups of tree thru the plates down to about 2 -3 inches. The larger project was cut down to about 4 inches. This cut back will force all the energy into only the four inches of trunk and swell a lot. If I left the trunks 5 feet long the shoots would only increase the trunks right out on the ends of the trunks, 14 inches away from the holes I need to fill. With the trunks now only four inches tall, the new shoots will direct all the energy into the trunks and they should swell to fill the holes by June. The tree was checked and the buds are swelling and now is the right time to cut the canes. this will now force all the energy into the bottom.

This is how much larger the trees have to grow to fill the holes and begin layering.

The roots have been covered with a layer of the grow stones as well as what above the tile. just from the fact of being covered with soil the trunks will begin to emit roots.

Here are the five trunks cut back and ready for next years growth.

All the trunks were cut back to shoots or buds on the trunk. this is the safest method to insure the trunk will take off when the sap is on the rise.

Here are some of the other baskets of maples with the trunks all cut back ready for spring. These are all the seedligs I did under the screen. They have good movement as a benifit from the screen.

This is one of the larger seedlings done from the same batch. It is amazing how fast they grow if they are not stuted by having screen thrown over them. the squirrels did a number on this root connected pair as can be seen in the close up.

OMG, seeds again?   4 comments

Well Sunday after the swapmeet I was able to get my seeds in for this year. I bought seed from a different company and hopefully the germination rate will be better. I planted 400 seeds this time, and I plant on making more of the tridents under screen this time. This year I have a new idea which I will share when ready and plan on keeping the seedlings confined much longer than this year. Recently on a discussion forum post I saw some trident all twisted up on growing cascade style from a stone. I will try to introduce a yamadori style method to these tridents and see what I get. Many of these will also be grown in a clump so that they intertwine and graft together to make a larger trunk sooner.

This year rather than grow these in turface and sand I decided to grow these in Black Gold brand cactus soil. It is a blend of pine bark and pumice about 50/50. The bark is pretty coarse and I am sure it would work as bonsai soil also. Pretty easy to get at any home depot.

It should be an interesting year all around.

Seeds are up   2 comments

Well the seeds are starting to sprout now. Had some temps all week around 64. Still have cool nights but no frost expected. A couple more weeks and I can begin phase two of the seed growing process.

EDIT: About five more popped up today. By the end of the week I should have rows of maples. I planted some of the seeds in clumps. I can see a couple coming up where there is two in the soil. Tomorrow may have a better picture to show. The plant in the first photo is about 1 inch tall today.
