Red maple is a deciduous small tree belonging to the Aceraceae family, and it is one of the varieties of Acer palmatum. In spring and autumn, the bright red leaves of the entire tree have very high ornamental value and are often planted in gardens and courtyards, or in pots to create different shapes of bonsai. Below are some tips on how to care for a potted red maple.
I. Growth Habit Requirements
1. Light
Red maple enjoys sunlight but also tolerates shade, and it is sensitive to strong sunlight. It is suitable for light that is neutral and slightly shaded. Potted plants can be placed in areas with plenty of scattered light and get some sunshine.
2. Temperature
Red maple prefers cool temperatures, with an optimal growth range of 18 to 25°C. It can tolerate temperatures as low as -20°C, but potted red maples have lower cold tolerance and can be cared for on the balcony during winter.
3. Soil
Red maple does not have high demands on soil fertility, but potted red maples can be planted in soil rich in humus, which helps the plant grow lush and improves its resistance. It is suitable to use sandy loam that is loose, rich in humus, and neutral or acidic, generally using red maple-specific potting soil.
4. Watering
Red maple likes moisture but is afraid of waterlogging. The potting soil should be kept slightly moist. More water should be given during the growing season, especially in summer, when it should be watered twice a day in the morning and evening. In winter, less watering is needed, about once every 3 to 5 days.
5. Fertilizing
When potting or repotting for the first time, a base fertilizer should be added to the bottom of the pot. In autumn, nitrogen-phosphorus-potassium fertilizers can be used. During the growing season, fertilizing is necessary, with a thin liquid fertilizer applied every 15 days.
II. Management Measures
1. Disease and Pest Control
The main diseases and pests affecting red maples include powdery mildew, leaf spot, leafhoppers, caterpillars, and longicorn beetles. These need to be controlled in a timely manner using chemical sprays, and diseased branches and leaves should be cut and incinerated when disease occurs.
2. Pruning
Yellow leaves should be pruned promptly. After autumn leaf fall, shaping can be done by pruning excessive growth, diseased, dead, and crossed branches. Red maple leaves are usually red when new, turning green in summer, and red again in late autumn. To make the leaves turn red earlier, leaves can be pinched off in August to promote the growth of red new leaves.
3. Repotting
It is usually necessary to repot every 2 to 3 years, preferably in spring or autumn.
III. Propagation Methods
1. Cutting Method
Potted red maples are commonly propagated using the cutting method. This is usually done from June to July, taking healthy branches from the current year, about 20 cm long, as cuttings. The cuttings should be kept moist, and the cut ends should be dipped in 1000 mg/kg of naphthalene acetic acid for 5 seconds before inserting them into the propagation matrix, which should be a mixture of vermiculite and pond soil. After planting, they should not be exposed to direct sunlight and the soil should be kept moist, with roots forming in about 30 days.
2. Seed Planting Method
Red maple seeds mature from September to October and should be planted in the following spring after being soaked in cold water for one day to promote germination.
3. Grafting Method
Grafting is often done in early spring using 2 to 4-year-old Acer palmatum as rootstocks. Bud grafting can also be done in late autumn, using plump and complete buds from the current year's healthy short branches of red maple as scions. The leaf stalks of the grafted buds should be 1 cm long, and if the leaf stalks fall off when touched after 7 days, it indicates successful grafting.
