I've had a weeping cherry tree for about three years now. It was transplanted, and it was about 8 or 9 feet tall then. There were leaves on the tree, midsummer, I believe. She's done well ever since then except for the fact that every year up until this year she's bloomed about 5 blooms total each season. Last year she only bloomed 3 flowers. This year she's not bloomed at all, but she's putting out big beautiful leaves like always and growing like crazy. Any help would be greatly appreciated.

From what you say, your tree sounds pretty healthy if the leaves are plentiful. Possibly you have been too kind to it? Most flowering plants put out more flowers when there is a lack of nutrients in the soil. Cut down on the nitrogen fertiliser and use only potash and it should improve in a year or two. I have one in my garden - I never feed it at all and it flowers madly every year (this is its third spring and the buds are looking good again).
Generally, nitrogen encourages leaf and shoot growth. So cut back on the nitrogen. Phosphorus enhances energy production, and greatly helps with flowers and fruit (high energy users), potash helps with overall health. So less nitrogen and more phosphorus (bone meal) and potash (wood ashes) should help a lot with flowering.
And to the people that have trees with no buds - either at home or at the nursery, cherry buds are quite visible, if there are no buds its dead. If it is at the nursery or Home Depot - don't buy it unless it has full visible buds.
We have a weeping cherry tree which has been planted in the same position for approximately 5 years and each year it has an average of about 1 flower a year.
I feed it regularly every 4 months with Dynamic Lifter and have it on a dripper system for watering in the summer. I read in June of this year that you can feed monthly with a solution of Epsom salts (1 teaspoon per 2 litres of water), but still it has only 1 flower. My wife has come up with a solution of treating it with an axe therapy, but I would like to to keep trying as the leaf growth is very strong and it is a healthy tree. Any suggestions or hints would be valuable.
Weeping Cherry Tree not blooming
1. You must prune it. Overcrowded branches don't bloom.
2. Fungal disease.
3. Winter damage- prune damaged parts off.
They often don't bloom until they are 6 years old or older, so that you have had any blooms is pretty amazing...of course, that is where I am, not sure what zone you are in.
This site has the best info I have found about them.
This site warns about over pruning as it takes away from the graceful waterfall (weeping) look.
Another good point this article makes is to avoid pesticides whenever possible since these lovely trees are so popular with wildlife.
It talks about fertilizing needs also....which I may be the naysayer about, but I disagree with and rarely fertilize anything.
Sending your tree lots of healthy wishes and the hope that next year it hits its magical full bloom glory!!

A: Hi Susan,
Here is what I know about cherry trees. Regardless of the variety, most of them prefer full sun and well-drained soil. Did either of these conditions change from the backyard to the front yard? Cherry trees are also easily damaged by planting them too deeply, or by allowing mulch to remain against the lower trunk.
In general, the older the tree (assuming it's a bare-root tree and not a tree from a container) the more susceptible it is to transplant shock because it usually requires severing a greater number of large roots. Cherry trees respond well to fertilizer. If you're sure your tree is still alive, I would suggest giving it a boost of tree fertilizer in March. Use one especially formulated for cherry trees and apply it around the drip line in the amount directed on the package.
Another thing to pay attention to is whether or not other flowering trees in your area are doing anything. If they are, then your tree either suffered some kind of stress when you moved it or the soil or light conditions are no longer supporting it. Just like people, older trees can need extra time to adapt to change. If it's still alive, there's a good chance it will come back.
Your tree is probably suffering from transplant shock. It may take 1-3 years to recover and return to normal blooming. Is the sun/shade exposure differnt than the original location? Is the soil wetter or drier than the original location? Both of these can affect the tree's recover and ultimately its survival. (02/27/2006)
