A Detailed Guide to the Latest Cultivation Methods for Spiderwort
Spiderwort, also known as purple spiderwort and purple-leaf spiderwort, is a perennial herbaceous plant of the genus Tradescantia in the Commelinaceae family. It is native to the tropical regions of the Americas and has been introduced and cultivated in China. Its plant form, flower buds and inflorescences are suitable for ornamental viewing, and it works well for mass planting in flower beds and along both sides of roads. It can also be grown in pots for indoor display or as a hanging plant. Now let us take a look at the cultivation methods for spiderwort!
Growth Habits of Spiderwort
Spiderwort prefers a warm, humid, semi-shaded environment and is cold-tolerant. The most suitable temperature is between 15 and 25°C. It has low soil requirements and can grow normally in sandy soil or loam. It dislikes waterlogged soil and grows well in neutral or slightly alkaline soil. After acclimatization, it can overwinter outdoors. Using plastic film as insulation cover for overwintering can advance the flowering time to mid-to-late April. Root tillers and axillary buds can sprout new shoots multiple times during the growing season, and flower buds can form at the tip of each shoot.
Propagation Methods for Spiderwort
1. Division: Division propagation of spiderwort is generally carried out before sprouting in early spring, because in early spring the temperature is not high, the plant's transpiration is low, and the cut surfaces are not prone to rot. Therefore, when propagating, a vigorously growing, well-shaped plant can be selected as the mother plant. After digging it out, remove the soil from the roots and cut apart the clustered root tillers with a small knife, so that each piece has 2 to 3 buds.
2. Cuttings: There is no specific requirement for the timing of spiderwort cuttings. Cuttings in a hotbed can be done in any period throughout the year, while cuttings in a cold frame can be done except during the winter dormancy period, with the rainy season being the most suitable time. After cutting, attention must be paid to water control, ensuring sufficient watering and soil moisture in the cutting bed. After 4 days, watering can be appropriately reduced, keeping the soil surface from drying out, to promote rooting. After half a month, most of the plants have rooted.
Cultivation Methods for Spiderwort
1. Temperature: The optimum growth temperature for spiderwort is 18 to 30°C. It dislikes cold and frost, and the overwintering temperature needs to be kept above 10°C. When the winter temperature drops below 4°C, it enters a dormant state. If the ambient temperature approaches 0°C, it will die from frost damage.
2. Light: Spiderwort fears direct strong light and needs to be kept in a semi-shaded place or shaded by 70%. When kept indoors, place it in a bright spot as much as possible, and every one or two months move it outdoors to a semi-shaded place or shade it for a month, so that it can accumulate nutrients and restore its growth vigor.
3. Fertilizer and Water: Spiderwort has high fertilizer and water requirements, but it is most afraid of random fertilization, concentrated fertilizer, and one-sided application of nitrogen, phosphorus or potassium fertilizer. It should follow the fertilization (and watering) principle of “light fertilizer applied frequently, small amounts with more applications, complete nutrition.” Applying a compound fertilizer once every two weeks is sufficient.
4. Pruning: During cultivation, in order to keep the plant shape attractive and extend the autumn flowering period, the old stems should be renewed to promote the growth of new tiller buds. At the same time, promptly remove spent flowers and dead branches and leaves to promote the development of new flowers and leaves.
