Some time ago, I also bought some clematis seedlings. At first I thought it was hardy, so I left it outside in winter without protection. In spring, I found that the roots were frozen to death. Some seedlings blossom in the second year, while some seedlings have not flowered until now. Clematis is good-looking, but it is really difficult to raise. How to say, two trees of the same species use the same maintenance method. It is very likely that one of them does not blossom or has Fusarium wilt, but you just don't know why.
With four years of experience in planting clematis, I have summed up some for your reference, at least when you accidentally pick up a clematis by the side of the road, you can raise them directly without being in a hurry.
12 Tips for raising clematis:
1. When you buy clematis, clematis usually have labels with their names and groups written on them, which are tied to flowerpots or branches, in case you suddenly can't remember what it's called one day. Otherwise, it's hard to look up information on the Internet when you're sick. Because the clematis of my own three kinds of red flowers look alike, I can't tell who is which now.
2. Clematis newly bought in early spring, especially those that have sprouted, because the buds are very delicate, you can first plant them in small flowerpots and keep them indoors with high temperature, and then plant them outdoors or change large flowerpots after mid-May.
3. The bigger the seedlings bought by clematis are, the faster they grow, and the more likely they are to blossom that year. Of course, it is better for you to buy clematis with flowers.
4. The growth rate of different varieties of Clematis is different, this is not a disease, do not make a comparison between different varieties.
5. Clematis has well-developed roots and a high demand for fertilizer, so the flowerpot should not be too small. When you plant it, you should put as much humus as possible.
6. When planting clematis seedlings, you should bury 1 or 2 bud points. This has two advantages: one is that the underground part can take root and the plant is more luxuriant; the other is that when the plant has Fusarium wilt, it can leave uninfected branches because there are roots in the ground.
7. No matter what variety or classification of clematis, it is best to cut it to 20-30 cm off the ground in the second and third year, so as to avoid top-heavy.
8. In contrast to the above suggestion, no matter what variety or classification of clematis, you can avoid pruning. This is only a matter of aesthetic appreciation and does not affect the growth of flowers.
9. If Fusarium wilt occurs in potted clematis (you must make sure it is Fusarium wilt, not because the leaves are dry due to lack of water) then you can cut off the withered stem, you will see black spots in the middle of the stem, cut and check again, until the section of the stem is clean, the rest of the healthy part can be saved, but it is hard to say whether it can be saved.
10. With regard to the acidity and alkalinity of clematis soil, the pH value of neutral soil is the best, and weak alkalinity and weak acidity do not affect it.
11. With regard to fertilizer, if you are lazy, you can use rose fertilizer directly, which is simple and feasible.
12. When buying clematis, I suggest that you buy that kind of short, compact variety of large flowers, which does not take up space to look good.
