A string of red, also known as Western red, red under the wall, firecracker red, is a perennial herb of the family Lamiaceae and Salvia. It has a warm, warm climate and a well-lit environment. The corolla is red. A string of red normal flowering period is from September to November, but after special management and conservation, it can also be repeated many times a year.
In the middle and late November, a string of red pots growing vigorously were moved into the room and placed in a sunny position to be trimmed. Only the lower 2nd to 3rd leaves were left, the upper part was all repaired, and the top dressing was applied for about 7 days to promote The buds grow into new shoots. From mid-December to early-December, indoor cuttings will be made, and the robust shoots will be cut from 5 cm to 7 cm long for cuttings, which should be intercepted at 0.5 cm from the festival. Leave 2 to 3 parietal leaves, and remove the remaining leaves. Insert them into the culture soil to a depth of 1/3 of the total length. Pour enough water to make roots at room temperature of 15°C to 25°C for about 18 days. Pots can be maintained. From January to February, the new plants were harvested one to two times to promote long lateral branches. In the middle of March, the heads were set, leaving 5 to 7 shoots per plant, applying 1 to 2 liquid fertilizers per month, and Spraying potassium dihydrogen phosphate 1 times, promoted flowering in mid-late April, bright and flourishing. After the flowers were planted in May, they were trimmed, leaving only 2 leaves for each branch. The upper part was trimmed, top dressing was applied for 10 days or so, and bloomed from late June to mid-July. In early August, the above pruning method was repeated and the head was set in the middle of the month to allow the plants to enter the flowering stage before the National Day and decorate the festival. Thanks to the above operation in early October, a series of red flowers will bloom again in the middle or late November.
To make a bunch of red flowers many times, the key is to timely pruning after flowering, and at the same time, strengthen the management of water and fertilizer so that the axillary buds grow into flower buds. When the new branch grows to 4 pairs of leaves, it produces flower buds and the 5th section forms flower buds. As long as the right temperature, adequate water and fertilizer, and diligence in pruning are guaranteed, more than one year can be realized.
