(1) Maintenance and management

Placement: Triangle maple is a weak positive tree species that likes temperature and is resistant to moisture, so it should be placed in a ventilated, light-transparent and relatively humid place. In summer, the temperature is high and the sunshine is strong, so a little shade is needed to prevent sunburn and dryness. In winter, it can be kept indoors for overwintering.

Watering: Triangle maple is more tolerant of water and moisture, so the pot soil should be kept moist at ordinary times. During the vigorous growth period in spring and summer, the pot soil should be slightly moist, not dry. In autumn, the leaves turn red and growth slows down. The pot soil should be kept slightly dry to prevent leggy shoots in autumn.

Fertilization: It is advisable to topdress several times during the growth period in spring and summer. Use thin decomposed cake fertilizer and water to ensure "thin fertilizer is applied frequently". Fertilization should be stopped during the rainy season and after the leaves fall in autumn.

Pruning: Triangle maple has strong germination and is very resistant to pruning. Unnecessary long branches and overly dense branches can be cut off at any time to maintain a certain tree shape. A pruning can be done during the dormant period in winter.

Repotting: It should be done every 2 to 3 years. It is advisable to repot before germination in spring, or after leaf fall in autumn. When repotting, you can combine root pruning, remove some old roots, replace the old soil with a ratio of 1:2, cultivate it with fertile and loose leaf mold soil or garden soil, mix in an appropriate amount of rice bran ash and sand, and put some cake fertilizer scraps on the bottom of the pot. Base fertilizer to promote root development and luxuriant branches and leaves.

Pests and diseases control: The main diseases of triangle maple include brown spot and powdery mildew; the main pests include thorn moth, damselfish moth and beetle, etc. Bordeaux mixture or lime sulfur mixture can be sprayed to prevent and control diseases, spraying 80% Dichlorvos emulsion 1500-2000 times to control insect pests.

(2) Appreciation

The triangular maple tree has a graceful appearance, beautiful leaf shape, and three shallow lobes at the end of the leaf, just like a duck's web, which is quite enjoyable to watch. At the beginning of spring, new leaves first bloom, which are delicate and green; after autumn, the color of leaves turns to dark red or old yellow, which is more pleasing to the eye. For example, in late summer and early autumn, remove the old leaves and apply a quick-acting nitrogen fertilizer. Half a month later, fresh and tender new leaves, light green or reddish, will appear, which can increase its ornamental effect.

2. Plant in the ground to refine the base, plant shallowly and cultivate high. Permeable roots.

3. Moisturizing management in the first half of the year, no fertilization; later, gradually fertilize, until large fertilizer and water are available, then stocking.

4 In the first year, the buds are basically left untouched and the branches are not pruned. In the second year, the buds are pruned and the buds are pruned, the stems and branches are fixed, and they are stocked.
