Don't cut the red leaves in summer. Cutting the leaves is doing you a disservice.
In early summer, it is in the flower bud differentiation stage and needs more nutrients. If the leaves are too long and pruned at this time, and the fertilization fails to keep up with it, the growth and even flowering of the plant will be affected.
In midsummer, the sun is abundant and the temperature is suitable, which is the vigorous growth period of the red. The more leaves, the more nutrients the plant produces for photosynthesis, the healthier the plant is, and it is more conducive to flowering next year.
In summer, the more vigorous the leaves are, the larger the photosynthesis area is, and the more nutrients are accumulated. Generally, the total number of leaves of a single plant is no less than 5-6, the more the leaves, the easier the flowering.
If the plants are not divided at this time or the flower urging treatment is carried out, the leaves shall be kept as much as possible, and then they will fall naturally. This is because the leaves will carry out photosynthesis and accumulate nutrients before the red flower is dormant. The longer the leaves stay, the more favorable the growth of corm.
