The breeding mode and culture method of Tradescantia!

Purple dew grass, also known as purple duck toe grass, purple leaf grass, etc., is a perennial herb of the family Euphorbiaceae, which is native to tropical America. It has a good effect on planting on both sides of flower beds and roads, and can also be planted indoors or for hanging cultivation. Propagation and breeding methods of Tradescantia!

I. the growth habits of Tradescantia.

Tradescantia likes warm, humid and semi-overcast environment, cold-resistant, the most suitable temperature is between 15 and 25 ℃, it can grow normally in sandy soil and loam, avoid stagnant water in soil, grow well in neutral or alkaline soil, overwinter in open field after domestication, cover it with plastic film for heat preservation, advance flowering time to mid-late April, root tillers and axillary buds can sprout new branches many times in growing season. And flower buds can be formed at the top of each branch.

Second, the propagation method of Tradescantia.

1. Ramet propagation

The ramet propagation of Tradescantia is generally carried out before sprouting in early spring, because the temperature is not high in early spring, the transpiration of the plant is small, and the incision is not easy to rot, so the plant with exuberant growth and good shape can be used as the mother plant during propagation, and the root soil can be removed after digging out. The cluster root tiller can be cut with a knife, and there are 2 to 3 buds on each piece.

two。 Cuttage propagation

There is no specific requirement for the cutting time of Tradescantia, the cutting time of the hotbed can be carried out in all periods of the year, the cutting time of the cold bed can be carried out except the dormant period in winter, and the most suitable time is the rainy season, and attention should be paid to water control after cutting. ensure adequate watering and soil moisture in the cutting bed, properly reduce watering after 4 days, keep the soil surface not dry, promote rooting, and most plants have taken root after half a month.

Third, the culture method of Tradescantia

1. Pay attention to temperature

The optimum growth temperature of Tradescantia is 18: 30 ℃. Avoid cold frost. The overwintering temperature needs to be kept above 10 ℃. When the winter temperature drops below 4 ℃, it goes into dormancy. If the ambient temperature is close to 0 ℃, it will die of frostbite.

two。 Proper illumination

Tradescantia is afraid of strong light, so it needs to be preserved in semi-shade or shaded by 70%. Keep indoor in bright light as far as possible, and move to outdoor semi-shade or shade for a month every one or two months, so that it can accumulate nutrients and restore its growth.

3. Fertilizer and water management

Tradescantia requires a lot of fertilizer and water, but it is most afraid of random fertilization, concentrated fertilizer and partial application of nitrogen, phosphorus and potassium fertilizer. It is required to follow the principle of "light fertilizer applied frequently, less and more times, and complete nutrition". Compound fertilizer can be applied once every two weeks.

4. Timely pruning

In order to maintain the graceful plant shape and prolong the autumn flowering period, the old stem should be renewed to promote the growth of new tiller buds. At the same time, the timely removal of abortive flowers and withered branches and leaves can promote the development of new flowers and leaves.

The above is the introduction of the breeding methods and culture methods of Tradescantia. Tradescantia likes water and is afraid of waterlogging. During the growing period, it should be watered in time and pay attention to eliminate stagnant water. At the same time, timely removal of failed flowers and withered branches and leaves can promote the development of new flowers and leaves.
