In addition, when there are dead leaves, the diseased leaves need to be cut off in time.

Second, the pruning method of colored leaf grass.

1. Topping

Topping, also known as coring, is one of the main means to control the plant height and germination of lateral branches. When the plant grows 4-6 leaves in the seedling stage, the heart should be removed many times and the top growing point should be removed to promote the growth of lateral branches.

2. Thinning cut

In the vigorous growth period, its growth rate is relatively fast, if the branches and leaves are too luxuriant not only affect the beauty, but also lead to the lack of light in some leaves, how to trim the colored grass at this time?

Maintenance of colored leaf grass after pruning

1. The light is sufficient. After pruning, coloured leaf grass should be maintained in a bright place, and if it is in spring, it can be maintained in the sun, not in the dark, because pruning is for the growth of new branches. lack of light will lead to slow growth of new branches, the role of pruning can not be maximized.

2. The temperature is moderate. After pruning, the temperature should be kept between 18 and 25 degrees as far as possible, which is the most favorable temperature for the growth of colourleaf grass, and the growth rate of lateral branches is also the fastest in this environment.

Select branches from 1-2-year-old strong colored leaf grass plants, usually the branches with terminal buds are the best.

3. Make cuttings

Cut the selected branches into cuttings 5-10 cm long, trim the leaves at the base, retain 3-5 leaves, and need 3-5 nodes on each cuttage. The excess leaves are cut off to avoid the loss of nutrients.

4. Cuttage

After making cuttings, how does colourful leaf grass reproduce? The cuttings will be cut in the prepared basin soil, and then the soil near the cuttings will be compacted, appropriate watering to keep the soil moist, but do not allow stagnant water in the basin.

5. Post-management

After cutting, keep it in a cool and ventilated place, keep the temperature not lower than 18 degrees, and pay attention to the moist condition of the soil.

3. Sowing seeds

Sowing is the most suitable breeding method for large-scale houses, but because the seeds are relatively small, in order to spread evenly, it is necessary to mix the seeds with fine soil, and then scatter 2-3 seeds in each hole. Cover with 2-3 mm thick soil, then compacted and watered.

4. Management

Sowing needs to be controlled at about 20 degrees, and seedlings can emerge in 10-15 days. After emergence, the temperature needs to be controlled at 16-18 degrees, after the true leaves grow out, they can be cultivated into seedlings, and after the seedlings grow to 6-10 cm, they can be cultivated in soil.
