Culture methods and matters needing attention of Tradescantia

Because of its long flowering period, erect stem, obvious node, leaf sheath, peculiar and beautiful plant shape, Tradescantia has + foot game. Planted under the bushes, matched with long leaves of irises, ornamental plant shape and flower buds, inflorescences, outstanding features, unlimited interest. It can be used for flower beds and planting on both sides of the road. it can also be potted for indoor decoration, or for hanging cultivation.

Cuttage propagation

The branches used for cutting are called cuttings. Cut the stem into 5-8 cm long segments, each with more than three leaf nodes, and the top tip can also be used as cuttings.

Attention should be paid to management after cutting:

(1) temperature: the optimum temperature for cuttings rooting is 18 degrees Celsius ~ 25 degrees Celsius, lower than 18 degrees Celsius, it is difficult and slow for cuttings to root; when the temperature is higher than 25 degrees Celsius, the cutting □ of cuttings is easy to be infected by bacteria and rot, and the higher the temperature, the greater the proportion of rot. When there is a low temperature after cutting, the heat preservation measure is mainly to wrap the flowerpot or container used for cutting with thin film; when the temperature is too high after cutting, the cooling measure is mainly to shade the cuttings, to cover 50-80% of the sun, and at the same time, spray the cuttings 3-5 times a day, with more times of spraying in sunny days, lower temperature and humidity in rainy days, and less or no spraying times.

(2) humidity: the relative humidity of the air must be kept at 750.85% after cutting. You can increase the humidity by spraying the cuttings 1-3 times a day, the higher the temperature in sunny days, the more times you spray, and the lower the temperature in cloudy and rainy days, the less or no spraying. But with excessive spraying, cuttings are easy to be infected by bacteria and rot, because many kinds of bacteria exist in the water.

(3) Light: cutting propagation is inseparable from sunlight, but the stronger the light is, the higher the temperature in the cuttings is, the more exuberant the transpiration of cuttings is, and the more water is consumed, which is not conducive to the survival of cuttings. Therefore, the sun must be shaded by 50% to 80% after cutting.

Tradescantia is the most suitable to reproduce in autumn, and its advantages are as follows:

① is easy to survive, grows rapidly, and can fill the pot in a short time.

② growth stem is not high, growth leaves are more prosperous, easy to grow in winter.

③ will bloom a lot in the coming year, and it will be beautiful.

It is suitable for cutting to propagate in autumn. Cut the old stem about 10 cm, cut it flat under the node, insert it for half a year, and take root after half a month, and sprout from the side. Culture methods and matters needing attention of Tradescantia

English name: Tradescantia

Alias: purple duck toe grass, purple leaf grass

Latin scientific name: Tradescantia albiflora

Families and genera: Commelina of the family Commelina

Distribution of origin: Mexico

Because of its long flowering period, erect diameter, obvious nodes, leaf sheath, sufficient sunshine, but also able to withstand semi-shade, Tradescantia is strong and cold-resistant, so it can survive the winter in open field in North China. It is not strict with the soil. Because of its peculiar and beautiful plant shape, full game, planting under the bushes, matching with long leaves of the tail, ornamental plant shape and flower buds, inflorescences, outstanding features, unlimited interest. It can be used for flower beds and planting on both sides of the road. it can also be potted for indoor decoration, or for hanging cultivation. Flower words: respect.

I. growth habits

Tradescantia prefers warm, humid and semi-shady environment, is not cold-resistant, and the optimum growth temperature is 18 ℃ ~ 30 ℃. It avoids cold frost and is not strict with the soil, but it grows more vigorously in loose and fertile sandy loam.

II. Reproduction and cultivation

Cultivation: the cuttage method is used for propagation. It should be maintained under the shade. If thin fertilizer is applied once in 20-30 days, the basin soil should be kept moist. Fewer diseases and insect pests.

III. Cultivation and management

1. Cutting propagation: the branches used for cutting are called cuttings. Cut the stem into 5-8 cm long segments, each with more than three leaf nodes, and the top tip can also be used as cuttings. Attention should be paid to management after cutting:

(1) temperature: the optimum temperature for rooting of cuttings was 18 ℃ ~ 25 ℃, which was lower than 18 ℃, and it was difficult and slow for cuttings to take root, and when the temperature was higher than 25 ℃, the cuttings were easily infected and rotted by bacteria, and the higher the temperature was, the greater the proportion of rotting was. When there is a low temperature after cutting, the heat preservation measure is mainly to wrap the flowerpot or container used for cutting with thin film; when the temperature is too high after cutting, the cooling measure is mainly to shade the cuttings, to cover 50-80% of the sun, and at the same time, spray the cuttings 3-5 times a day, with more times of spraying when the temperature is higher in sunny days, lower temperatures and higher temperatures in rainy days, but less or no spraying times.

(2) humidity: the relative humidity of the air must be kept at 750.85% after cutting. You can increase the humidity by spraying the cuttings 1-3 times a day, the higher the temperature in sunny days, the more times you spray, and the lower the temperature in cloudy and rainy days, the less or no spraying. But with excessive spraying, cuttings are easy to be infected by bacteria and rot, because many kinds of bacteria exist in the water.

(3) Light: cutting propagation is inseparable from sunlight, but the stronger the light is, the higher the temperature in the cuttings is, the more exuberant the transpiration of cuttings is, and the more water is consumed, which is not conducive to the survival of cuttings. Therefore, the sun must be shaded by 50% to 80% after cutting.

2. Transplanting: when the seedlings are installed in a pot, a coarse-grained matrix or ceramsite with a thickness of 2cm or 3cm is placed at the bottom of the pot as a filter layer, and then sprinkled with a fully mature organic fertilizer as the base fertilizer, with a thickness of about 1cm and 2cm, then covered with a layer of substrate, about 1cm thick, and then put into the plant to separate the fertilizer from the root system and avoid burning roots. You can choose one of the following substrates for potting. Vegetable garden soil: slag = 3RU 1; or garden soil: medium coarse river sand: sawdust = 4RU 1RU 2; or one of paddy soil, pond mud, rotten leaf soil. Or peat + perlite + ceramsite = 2 + 2 + 1; vegetable garden soil + slag = 3 + 1; peat + slag + ceramsite = 2 + 2 + 1; sawdust + vermiculite + medium coarse river sand = 2 + 2 + 1. After putting on the basin, pour water once and keep it in a shaded environment.
