Creating black pine bark cork

After doing some trimming a black pine corkbark, I saved the clippings so I could do some graft. corkbark pines are not as strong on their own roots as they are at the roots of black pine. As a result, most of the bonsai corkbark we are grafted. The earlier these trees are grafted, the better. About 3 years old, young black pines can be used to house corkbark pine stems.

The first step is to make room for the stem. I did this by removing low branches and needles.

At this point I had a flashback of a pine tree was grafted many years. After making a successful graft, I realized several years later, he had attached the rod too high on the trunk. Before grafting of this young pine, I took the floor until I found the rootbase.

This pine seedlings was created by cutting. A few months later sprouted tree, cut out the taproot in the hope of replacing it with many lateral roots. I was surprised, however, to find that only one root had translated. For the sake of the graft, I took more and more land until I found the place where the roots began to divide. I prepared to fix the stem just above this point.

One new root!

prepared me stems by removing half of their needles. The trick is finding the right balance – I want to keep as many hands as possible, but not so many that the stem will dry quickly. In this case, I have kept about five pairs.

Then cut the barb base of a pointed tip and inserted into the stem of the seedling. The important part here is to align the cambium layer of the scion with the host. When the rod is thinner than the host, I try to align the cambium on one side of the prong instead of focusing the stem and missing on both sides. The two photos below show the side that not align well.

After inserting the rod, I covered my with a plastic bag filled with a pinch of wet moss New Zealand. I tied all the grafting tape and moved to the next seedling. The final step is covering the bags with tape to prevent the sun from drying the stems.

usually, the pines are quite active in January where I live as winters tend to be so cold. This year, however, has proven to be much colder than normal, and within a few days there was a lot of frost and the soil froze my trees. This may have been too much for the stems, but can not know for sure for several months. Fingers crossed!
