Douglas maple

Douglas maple should be watered once a week with about 1/2-3/4 gallon (3-5 liters) of water per plant. It is best to water the plants in the morning, giving them time to absorb and use the water throughout the day. Be sure not to over water, as this can lead to root rot and other diseases. When checking the soil to see if the plant needs water, use your finger to lightly poke and inch or 2 into the soil. If the soil feels dry, it is time to water. If it still feels moist, then the plants do not need to be watered yet.

Douglas maple (Acer glabrum var. douglasii) plants thrive in areas with partial sunlight or filtered shade. In part-sun conditions, Douglas maple trees will need 4 to 6 hours of direct sunlight each day. This sunlight should be divided between morning and afternoon sunshine, or early and late hours rather than all at once. To get the most benefit out of direct sunlight, the sun should reach the top of the tree for at least 2 hours. Douglas maples can usually tolerate full shade, but growth and bloom production may decrease. To ensure optimal growth, they should have at least 2 to 4 hours of direct sun every day.

Douglas maple (Acer glabrum var. douglasii) should be pruned during late winter to early spring when the tree is still dormant and before active growth begins. Pruning should be light and should focus on removing dead or damaged branches, increasing air circulation, and creating a structure that will support the growth of strong limbs and a pleasing shape. Generally, no more than 25% of the total tree canopy should be removed in any given year.
