How to prune morning glories
Morning glory pruning: Pinching
Morning glories reproduce very easily, and most can be grown from seed. When the seedlings have 3-4 leaves, vines will begin to grow from the center; at this time, the first pinching should be done. After a while, vines will start to grow from between the leaves; when these have 3-4 leaves, pinch them again.

Note: Fertilizer should be applied promptly after each pinching. When fertilizing and watering, keep the fertilizer and water close to the ground to avoid getting the leaves dirty, which could cause them to fall off.
Morning glory pruning: Remove flower buds
Morning glories grow rapidly and can bloom in the same year they are planted. Flower buds will grow between the branches. After the flower buds form, the stipules below the flower buds can be cut off to promote the development of the flower buds. To ensure sufficient nutrient supply, some small flower buds can also be removed.
After flowering, promptly remove the withered flowers. If properly controlled and the temperature is suitable, morning glories can bloom 3-4 times a year.

Morning glory pruning: shaping
Potted plants: For indoor potted ornamental plants, a support can be set up when the seedlings grow to 6 cm tall, allowing them to grow twine. Alternatively, when the seedlings have 7-8 leaves, pinch off the top, leaving 4 leaves, to ensure that each plant has no more than 9 flower buds. This will ensure a full plant shape. If possible, hanging baskets can also be used for planting, suspending the plant in the air and pruning it regularly.

Ground planting: Morning glories planted in the courtyard can be used as hedge decorations. The principle of pruning is to ensure that each branch grows evenly. When nine vines have grown, they can be evenly distributed on the wall and tied to stop their growth. Soon, a hedge and flower wall will be formed.
