I planted the weeping cherry tree a year ago and it was doing great until this year. The leaves started to get brown and now the trunk is turning white. I already sprayed leaves and trunk with Bayers disease and insect control and no luck. Tree still looks the same. It looks like new branches are coming out from the bottom, but the top still looks bad. Should I cut the the sick parts and let it start again from the bottom?
Your tree is damaged by a very common disease called tree canker. Very often it is due to a fungus. This disease has to be treated very quickly and it could be a bit too late as your tree already shows a lot of damages and it is a disease easier to prevent than to treat. The damages that are symptoms of the disease to be watched, are the little bumps and the little splits on the trunk. You can still give your tree a chance with first a treatment with copper spray. Be very careful to do not overuse or overdose the copper spray. Copper spray is the best treatment against fungi but when overdosed it becomes dangerous for the environment (and the gardener too !). You can also try to dig out the little bumps you see on the trunks and treat the holes you make by doing so with tree wound painting or linseed oil. To prevent the disease, first get rid of all the little pieces of dead wood which are by your tree on the surface of your soil because they make a nice home for fungi. Every autumn "paint" the trunks of your fruit trees up to the base of their main branches, and the base of the main branches with a mix of lime. This is called to "whitewash". It is very important to whitewash the trunks because in the winter or early spring there are days when the bare trunks of the trees are heated by sunlight when the ground is still cold or even frozen and the temperature drops at night. The trees which are dormant at that time can "wake up" and start their activity too early or the trunks can start splitting because of the brutal changes of temperature and it is through these splits that the bugs or fungi can get inside the trunks and start damaging them.
My weeping cherry trees leaves have turned brown. They were green and beautiful just a month ago. What can I do?

Call a nursery and ask them the same question.

Two years ago in August, I planted two weeping cherry trees. The first of May we went over and the trees where fine. I went back over one month later and most of the leaves have fallen off and the few that are left are brown. We started the sprinkler system in April and increased the water time to 30 minutes every morning (before was 20). What would cause the leaves to die and drop?

We planted a weeping cherry a couple of months ago and are watching it die. The leaves are browning and the branches are empty where the leaves have already died. About 1/2 of the tree looks like this. I've read about shock, fungus, etc. and they all say to trim back the dead branches. The problem is, this would leave me half of a tree. It's only about 6 ft tall now, faces southeast for morning sun, clay soil, and average drainage. Any help would be appreciated.

I planted 2 of these trees only to have them both die. It turns out the spot I planted them in was way too wet and they drowned. Even though the ground looked dry, the hole would fill with water as it did not drain well due to our clayish soil. You might check yours for too much water.

We live in the middle of a small orchard that my husband and I planted. We've had all kinds of challenges with our trees.
Get yourself a 5 gallon plastic bucket (a fast food place might even give you one). Ask for an empty pickle bucket. About an inch and a half from the bottom, drill a 1/16th inch hole. Set the bucket by the tree and fill it with water.
Once a week with average rainfall and up to three times a week during particularly hot times.

Give your tree 15 gallons of water each week. Put a plastic bag in a bucket and poke a small hole in it for a slow drip, or use a hose with very low amounts of water to reach the roots. (09/27/2008)
