The clematis is a vine plant, has the reputation of "vine queen". It can be planted on the ground or in pots. Since most species of clematis will grow to more than two meters, it usually needs support, so we often see it planted on the wall or in front of the window, close to the fence or other shrubs. It's also fun to plant it amongst rocky rock formations in the garden. So, how do you keep clematis and what are the cultivation methods and precautions for clematis? The following gardener uncle give you an introduction! Plant Clematis 1. Planting substrate Clematis likes fertile well-drained alkaline loam, avoid waterlogging or summer drought can not retain water. The potting medium must be breathable. Give good media if conditions allow. If conditions permit, use only perlite and peat. Try not to use garden soil for potting.2. Watering principles Clematis soil should be dry and wet alternately, because its root system needs to breathe, potting soil needs to be dry for a period of time, but not too dry. Generally 2-3cm below the soil surface can be watered. If it is planted in a plastic pot, you can also lift it up to feel the weight. When it gets lighter, it's time to water. For clay pots look at the sides of the pot, if the pot turns white, it tells you that you need to water. Watering should be watered through, until the water from the bottom of the pot out. 3. thin fertilizer diligently apply clematis cultivation should be avoided in a hurry. When applying fertilizer, do not start too hard. Thin fertilization is best. If you want to apply heavy fertilizer, it must depend on what the situation is. Only large seedlings planted in the ground that are fertilizer-tolerant can be heavily fertilized in a short period of time under high temperature and high humidity conditions. Potted seedlings and small seedlings planted in the ground will suffice. Potted clematis 4. Appropriate temperature The optimum temperature for clematis growth is 15~17 at night and 21~25 during the day.When the temperature is higher than 35 in summer, clematis leaves will turn yellow or even fall off, and cooling measures should be taken in summer.In November, the temperature continues to decrease. When the temperature is lower than 5, clematis will enter the dormant period. in December, clematis completely enter the dormant period, the 1st and 2nd week of the dormant period began to fall off the leaves.5. Light conditions Clematis needs more than 6 hours of direct light per day, which is very favorable for its growth, although it will produce spots in hot weather. Plant clematis in pots in full light from fall to early spring of the following year without shading. As it enters summer, it should be protected from strong sunlight and properly shaded. Otherwise, it is easy to cause the aging, yellowing and poor growth of clematis leaves.6. There is no absolute rule for clematis pruning. But generally speaking, after flowering, if you don't need to keep seeds, you can cut off the next 3 branches and take cuttings. In the fall and winter, clematis goes dormant and should be pruned immediately. Usually small seedlings can be cut from the soil, and large seedlings can be kept with strong branches.

You can guide it along the track you want it to grow on. Tip Clematis is most afraid of wilting, so keep an eye out for pests and diseases. If you find red spiders or leaf-feeding pests, treat them promptly and move the potted plant to a ventilated area, not indoors or on a closed balcony. Pay attention to ventilation. If you find wilted parts, prune and root sterilize them in time and wait for their seedlings to recover.
