Geranium winter growth needs and dealing with geranium degeneration
The editor will tell you about the relevant knowledge of geraniums, the winter growth needs of geraniums and how to deal with the degeneration of geraniums, as follows:
If the winter temperature of geraniums is low, below 8 degrees, or you plan to let geraniums hibernate in winter, it is appropriate to cut around the end of October. If the winter temperature can meet the growth needs of geraniums, for example, there is heating indoors, then it should be pruned at the end of August in the north and the end of September in the south.
1. Most of the watering is reduced in the summer, the soil is dry, and therefore, a considerable amount of salt has accumulated in the soil. It is necessary to change the soil as soon as possible after summer to reduce the salt content and replace it with a larger pot to benefit root growth. During the soil replacement process, the roots may be inevitably damaged or pruned, so it is advisable to prune some branches at this time.
2. According to my experiment, early-flowering varieties start to bloom after 3 months of full growth after severe pruning, while late-flowering varieties take 4-5 months. And regardless of the variety, it takes about 4-5 months to regain a full plant after pruning. If pruning is too late, it will greatly affect the flowering time. Moreover, those that require vernalization, like large-flowered geraniums and angel geraniums, must complete pruning before vernalization. For example, I started vernalizing angels at the beginning of November, finished vernalization at the end of December, and saw buds in early January, and they are about to bloom now.
3. Under indoor winter care, phototropism can cause uneven growth of the plant, except for those in a solarium, especially for vigorous varieties like 910. It may be necessary to make additional small prunings on the long asymmetric branches to achieve a round shape. Therefore, it is better to have sufficient growth time before spring arrives.
However, on the whole, geraniums are herbaceous plants and can survive the winter indoors for several years, but from the perspective of flowering, three years is the limit for horticultural cultivation.
Friends can try to prune at the right time or use growth regulators to promote branching, combined with the most suitable fertilizer for geraniums, keeping the soil moist and the room temperature at 18-21 degrees day and night, and one-year-old seedlings can grow to a considerable size.
But if it's pruning at the end of the flowering season, it's completely different.

Red is the cutting position, and yellow is the new branches. Because even if the flowering branches sprout, they are weak buds, which can lead to overcrowded and poorly ventilated plants, and such pruning can help the plant have a round shape and good ventilation.
Of course, the cut parts can be used for propagation.
The above comprehensive method explanation about the winter growth needs of geraniums and dealing with geranium degeneration, I hope it can solve your problems with green plants.
