How much to irrigate

Clematis always need fresh and moist soil, similar to that found in undergrowth. They are particular plants, they require sun and heat on the foliage but shade and fresh at the roots. The roots need to be constantly in a water-rich environment. It is necessary to distinguish between plants in the garden and potted plants, in the first case it is necessary to provide an irrigation system that supplies the right amount of water. Watering must be abundant in spring and summer, reduced in autumn, suspended in winter. For potted plants, on the other hand, it is necessary to use sufficiently large pots, equipped with a good tank to store excess water not absorbed by the plant. Generally a method used to understand the plant's water absorption capacity is to water it with at least 4 liters of water, if water comes out of the tank then too much has been used, it should be reduced until the capacity of the saucer is reached.

How to cultivate

Clematis loves a soil rich in organic and moist substance. In many areas of the world it is a spontaneous plant, it loves the undergrowth and develops in height, clinging to natural supports, such as trees, walls and trellises. Reproduction takes place by seed but above all by cuttings, in November a 30 cm long branch is cut from an adult plant. After cutting the top you can put it in a container with wet peat, it will take a few months to see the first shoots. The planting requires more attention, the hole in the garden must be very deep and also very wide, generally around 50 cm. Since clematis needs a good supply of nutrients for the development of its inflorescences, it is necessary at this stage to use a good organic fertilizer. Before planting the plant it is good to also insert a mixture of gravel and ash to allow the water to have a good drainage and avoid dangerous stagnation. In the case of pot cultivation, it is necessary to use large pots and proceed by first inserting gravel and ash, then peat and fertilizer and finally it is possible to store the plant.

How to fertilize

Clematis needs frequent fertilization for the development of its inflorescences. It loves fertilizers rich in nitrogen, potassium and phosphorus and this is why mature manure of at least two years turns out to be the best fertilizer that can be added to this plant. The fertilizer should not be applied pure, since in addition to odor problems, it could cause problems to the plant's roots. It should be mixed with peat or sand. With the compost obtained it is necessary to cover the soil around the stem of the plant. To complete it is necessary to proceed with a light watering to allow the substances present in the fertilizer to reach the roots more deeply. Fertilization must be done throughout the vegetative period from spring to winter. It is good to be regular in the fertilizations, to foresee a fortnightly or monthly cadence according to the composition of the substratum of the plant.

Clematis: Exposure, diseases and remedies

The clematis plants like to be heated by the sun, however they are to avoid the positions both too sunny because the leaves could be ruined and those too shaded because no flowers would be produced. It is good to plant clematis in areas protected from the wind and direct sunlight, in this way the roots are guaranteed to grow quietly without sudden changes in temperature and to the plant to develop and reach the sunny area. Clematis is very often attacked by snails and insects that eat leaves that have just been born. It also suffers from diseases due to aphids and spider mites. It can also be affected by mold like the white sickness that almost always covers the flowers and the rot of the buds. In all cases it is necessary to carry out a rigorous pruning and a biological treatment based on water and natural soap, the treatment must be repeated several times until any trace of parasite has disappeared.
