Is September still soon enough for pinching? Get these flowers pruned now for a burst of blooms in autumn and winter

Recently someone asked:"It's already September, can I still pinch back my flowers at home? Will I prune them to death?" Actually, whether you can pinch in September depends on the plant. Not all plants are suitable, but if you pick the right species and prune at the right time, it can actually make them grow more vigorously and bloom more.

First, you need to understand what "pinching" really is. Put simply, it means pinching off the tender buds at the top of the plant so it does not keep growing straight up, forcing it to grow more side branches. But pinching has a "time window," and the key is to look at the plant's growth cycle: if it goes dormant in winter, grows leaves in spring, and blooms in summer, then do not prune blindly in September; but if it blooms in autumn and winter, or can grow all year round, then pinching in September is actually just right.

The ones you absolutely must not pinch in September include roses, gardenias, and jasmine. Summer is their peak blooming season, and by September they have already started preparing to"rest for winter." If you pinch the tops at this time, the new branches will not have time to grow strong before the temperature drops, making them prone to freezing damage in winter and affecting next year's blooming. So leave these flowers alone and let them steadily prepare for winter.

Here comes the key part! For these plants, pinch in September and they will absolutely surprise you later: the first must be the kalanchoe. Kalanchoe usually11 blooms from November to February of the next year, so pinching now is just right. Just find the top two or three pairs of small leaves and pinch them off with your hand. Do not be reluctant to do it - after pinching, it will send out new side branches from the leaf axils. The more side branches there are, the more flower buds it will have in winter. By then the whole pot will be full of flowers, much prettier than just one tall stem growing up. Remember not to water too much after pinching, and place it in bright indirect light; new shoots will appear in about a week.

The second is petunia. After petunias bloom once in summer, they can bloom again in autumn. Pinching in September is meant to"force a second wave of flowers." Cut the branches that have already bloomed shorter, leaving about10 cm, and trim off yellow leaves and weak branches while you are at it. After pruning, apply a light fertilizer, such as diluted compound fertilizer. In half a month you will see new branches emerge, and in October they can bloom again, still with bright colors.

The third is geranium. Geraniums dislike heat and basically"play dead" in summer. In September, when the weather turns cool, it is the perfect time to pinch them awake. Pinch off the tender tips at the top to promote side branch growth, so the plant shape becomes more compact and does not grow crooked. Moreover, after pinching, the new branches grow quickly,10 and by October they can form flower buds. Kept indoors in winter, the blooming can continue into next spring.

The fourth is succulents, such as Aeonium and Firestorm. September is the peak growing season for succulents, and pinching can give them a"head-bursting" effect. Use scissors to cut out the leaf core at the top, but be careful not to cut too aggressively; leave a few leaves for photosynthesis. After cutting, let the wound dry and do not let it get wet. After a while, many small side buds will sprout around the cut, gradually growing into a pot full of small succulents, which is especially cute.

Pinching in September should be done on a sunny day, not on a rainy day, otherwise the wounds rot easily; after pruning, do not expose the plant to direct sun immediately. First place it in a ventilated spot with bright indirect light for two days to recover; if you want the plant to grow quickly, after a week you can apply a light fertilizer, such as fermented rice water or diluted liquid fertilizer, but not too concentrated, to avoid burning the roots.

For September pinching, as long as you distinguish the plant's blooming and growing periods clearly and choose the right species, you can prune boldly. Your flowers at home will not only not die, but will grow more and more vigorously. In autumn and winter they can still bloom in a full pot. Go check right away whether you have any suitable ones at home!
