  • Plum trees prefer locations with a rather high exposure to sunlight to give good plums.
  • Think ahead: your plum tree will grow to its adult size within a few years, and it needs space to grow.
  • Over the first weeks, water regularly as long as it doesn’t freeze.
  • It’s better to water during the day, since nights tend to be much cooler.

Pruning Alsace damson plum tree

General pruning principles

It’s recommended to prune only what is strictly necessary because plum trees are delicate and wounds make it vulnerable to diseases.
After each cut, apply pruning paste like pine tar to protect the wood from fungus and other diseases.

Directional pruning

Nonetheless, you may perform directional pruning in the first year to shape the structure of the tree. The goal here is to thin out the shoots from the trunk to end up with 3 or 4 main branches facing outwards.

Like all pit trees, notably the cherry tree, pruning is performed at the end of the summer or in the beginning of fall.

After having harvested the plums

Once you have harvested the plums, remove dead wood and fragile branches.
Remove fruits that haven’t fallen from the tree – they are often diseased – and destroy them.

Also, remove suckers, which are those shoots that emerge at the base of the tree.
