Mirabelle plum trees are usually in full bloom between the beginning of April and the end of May. Gardens and public parks shine in a sea of wonderful white flowering trees. But what if the mirabelle plum just doesn't want to bloom in your own garden? You can find out possible reasons and suitable solutions here:
Why isn't my mirabelle plum blooming?
If a mirabelle plum does not bloom, this may be due to the tree being too young, poor site conditions or a lack of care. Flower formation can often be stimulated through regular tree pruning and optimization of site conditions.
- The tree is too young
- Poor site conditions
- Lack of care
Young trees take a little longer
If you are worried because your own mirabelle plum isn't blooming, you should know that the common information about flowering times is based on "adult" trees. Mirabelles up to five years old usually only bear a few flowers and little to no fruit. Knowing the normal flowering time only serves as a guideline for when to prune the tree. Some hobby gardeners even find that their fruit tree takes up to ten years to reach its rewarding flowering period. So if your mirabelle plum tree is still relatively young, there is hope. Maybe the time just isn't right yet.
Site conditions not optimal
However, if it is not a very young tree or if the mirabelle plum has already had a flowering period with magnificent white umbels, then the location could possibly prevent it from continuing to bloom fully. On the one hand, mirabelle plums have a somewhat harder time in cloudy, rather cool and rainy regions. There are also changes on site: Does the tree still get enough sun? Is the soil structure consistent? Are possible enemies like voles spreading and feasting on the roots? Check that the location is still as good as it was when planted. Otherwise, replant the tree.
Observe appropriate care
Mirabelle plums are generally considered uncomplicated and easy to care for, as long as they get enough sunlight. However, this does not mean that you should leave the fruit trees entirely to their own devices. Support the plant with regular pruning. For young trees under five years old, this serves to form a stable basic structure. Later, maintenance and rejuvenation cuts help to thin out the rapidly growing crown so that all branches, shoots and fruits receive sufficient light and air. If you discover any water sprouts, remove them. Because these are shoots that protrude steeply upwards, which cost the mirabelle plum tree unnecessary energy, which it may then lack when it flowers.
