Plum trees can add beauty to almost any landscape. Their green to reddish-green leaves, beautiful shape and delicate pink flowers are a welcome addition to almost any yard. Add in their sweet, savory fruit and you have a package that is almost too good to resist. The key to getting your plum to set on (or yield) the maximum amount of fruit is the health of your tree. Follow some suggestions to achieve the greatest number of blooms each season.
Prune your plum tree sometime between February and March, before any new growth appears on the tree. Use your shears and loppers to cut away all dead or diseased-looking branches.
Trim all branches that cross each other, that grow straight across the tree's canopy, or which grow at a downward angle. This should open the canopy of the tree to light and air, which will encourage blooms to set.
Cut or break off all suckers that are growing out of the tree's trunk, or which are growing up from the roots. Suckers are green branches that have a smooth skin but no real bark.
Fertilize your tree using a good fruit tree fertilizer. This will provide the nutrients that your tree needs to set on the maximum number of blooms.
Water your tree well. Watering twice weekly just before and during the blooming season will give your tree the energy it needs to bloom and to set the maximum number of blooms.
Add a layer of mulch that extends out at least 4 to 5 feet around the base of your tree. This mulch will help to retain water and keep your tree its healthiest.
