For Mountain Maple (Acer spicatum), water regularly during its first growing season to ensure the roots become established. During the growing season from spring to fall, water the plant once per week as long as rainfall is less than about an inch per week. If rainfall is consistent, then you do not need to water as frequently. During the hot summer months, water the plant twice a week to keep the soil moist. Reduce watering from autumn through winter. During this time, only water if the plant shows signs of wilting or drying out.

Mountain Maple plants typically require full sun for at least 6 to 8 hours a day, particularly during the summer months. During winter, when sunlight is usually less, Mountain Maples can get by with just 4 to 6 hours of direct sunlight per day. Mountain Maples are used to dry, sunny spots and can tolerate cooler temperatures down to -30 degrees Fahrenheit. All in all, Mountain Maples need enough sunlight to get their essential nutrients for growth and to retain their vibrant foliage colors.

Mountain Maple should be pruned during the late winter or early spring season. Begin by removing any dead, diseased or damaged branches. Then remove any branches that are growing too close together, crossing, or are contorted. It is best not to aggressively prune Mountain Maple as it will lead to a decrease in flower and fruit production. To maintain the maple's natural shape, only lightly prune a few of the newest branches each year. And always make sure to sterilize your pruners before and after pruning to avoid the spread of disease.
