What is the fastest growing pine tree?
According to the Arbor Day Foundation, the white pine is the fastest growing pine tree, growing approximately 1 to 3 feet each year before reaching maturity (80 ft.).
I have several large pine trees and eucalyptus trees on the hill behind my house. The leaves and needles find there way into my rose garden and flower beds. Will this prevent them from growing well, and is there anything I can do about it?
Both pine needles and eucalyptus leaves in themselves will not hurt your plants, but both needles and leaves are known to raise the acid levels in the soil they decompose in. This will not cause a problem for your plants as long as you regularly test the soil (which should be done anyway to make sure nutrients are balanced) and treat the soil if the acid levels get too high.
Here is information on treating high acid in soil:
What time of year do pine trees start to drop sap?
It can drop sap anytime of year, but typically it is worst in spring and fall.
I got a pine tree grow kit around Christmas. I planted the seed and it has grown to about 4 inches and has stalled over the past month or so. It seems sturdy and is green with a brown 'trunk'. I repotted it around the same time it stopped growing. Is it in shock? Could the pot be too big? I didn't think that would matter since they grow outside in an even bigger area.
If this happened after it was repotted, it could simply be focusing on growing roots. As long as the plant looks healthy overall, I would not worry about it. It should start to grow again in a few weeks, particularly as the weather warms up.
Can a three-inch pine tree branch be repaired when broken halfway through?
You can put a splint on it like you would a broken bone and sometimes the bark will heal back. But the splint will always need to remain.
I had a big pine tree and my husband cut all the branches. Now only the big trunk is left. Is it possible that the branches and leaves will return? I feel very sorry seeing my tree like that and I don't know if the pine is dying due to the damage done to it. Please tell me what can I do.
