Pruning Techniques Before Winter
Pruning is an essential step in preparing your American plum tree for winter. Proper pruning lets the tree direct its energy to the healthiest branches, ensuring better growth in spring. Begin by removing any dead or diseased branches, as these can become entry points for pests and diseases. Aim to prune in late fall, when the tree has entered dormancy, to minimize stress on the plant.
Watering Schedule Changes
Adjusting the watering schedule of your American plum is crucial as winter approaches. Reduce the frequency of watering as the temperatures drop, but ensure the soil remains moist—not waterlogged—before the first hard freeze. This helps the tree sustain itself without drawing too much water during dormancy. Aim to water generously in late fall, around 10-15 liters (2.5-4 gallons) per tree, to keep the roots hydrated without risking root rot.
Soil Mulching
Mulching is a highly effective way to protect the roots of your American plum from freezing temperatures. Apply a thick layer of organic mulch, such as straw or wood chips, around the base of the tree, extending out to the tree's drip line. This insulates the soil, helps retain moisture, and prevents the ground from freezing too quickly. Apply about 5-10 centimeters (2-4 inches) of mulch for optimal protection.
