I've seen trees with the lower trunks painted white in a number of places around the world but have never found a definite answer to why this is done. Some suggestions that I've heard are to make them more visible at night time so people don't walk…
Our redwood is about 30 years old and about 4 stories high. I would like to shape and top it to keep under control. Would it be fine to top off about 10 or 15 feet and also shape it? A tree trimmer told me it would be a good idea but years ago…
I've always thought lichens were neutral to tree health, and I think they are attractive, but someone recently told me to get rid of them, because they will cause rot and harbor disease. Do they really do that? Is that why so many trees have hollow…
I moved into this house last year, so I've only seen this tree with leaves once and I do not know what kind of tree it is (I live in Iowa). I noticed this spring that the leaves didn't seem to come in very strong this year, and I noticed some…
I live in Arizona. I have a 2 year old avocado tree in a pot, not in the ground. Last week it was exposed to the extreme heat wave that hit us. I made sure the soil was moist every day. Twice a week I use the pond's backwash to water it. This week…
I have about 20 arborvitae trees along my driveway and all are browning. I'm a new homeowner and do not know the trees' history. What sort of issue do the below pictures exhibit? Thanks.
I am in Long Island, NY. I am pretty sure the browning was…
We moved into a house a little over a year ago. We really love this particular small tree that's in the front yard. One day I noticed that it had two holes in it, one towards the center and one near the ground. Both of the holes looked kind of…
I've had it for 7 years and in the last 2-3 months it has been losing all of its leaves. In an attempt to save what is left of it, I transplanted it today into a larger pot with fresh organic soil. i think, looking around online, i've overwatered…
My pecan tree has hundreds of holes, apparently made by a woodpecker. What is the best treatment to assure that no other damage from fungus or other infestation is incurred on the tree?
It is mid-September update in New York state. The leaves are already falling and have spots on them. Neighbors' trees are still green.
Is it normal? Or my tree is infected with some disease?
We are building a granny flat and have had to lose half of a two forked gum tree. The edge of the flat will sit over the stump with the rest of the tree behind it. Is there anything I can paint on, or do to the stump which will prevent regrowth…
I let some of my weeping trees grow as they wish. My neighbor says I should prune them the so that their branches do not touch the ground. He could not say why, just says it is bad for branches to touch the ground. Does that make sense? The trees in…
