Delphinium


How and how much to water


The development of the Delphinium is characterized above all by a remarkable rapidity, especially at the beginning of the vegetative period. This is a moment of vital importance for the plant that must, therefore, be watered in the best way and respecting, above all, the cultivation needs of the same. Generally, from March onwards it is necessary to administer good quantities of water, watering very frequently. In all this, however, it is absolutely necessary to remember that Delphinium does not tolerate water stagnation at all and, therefore, it is necessary to avoid soaking the ground excessively. After flowering it is possible to reduce the irrigation that must be suspended starting from the autumn season. The soil must be, between one administration and another, very dry and free of previous residues.

Cultivation and care



The cultivation of Delphinium is characterized by extreme simplicity. In fact, it is not rare that with very little effort it is possible to obtain beautiful blooms and, above all, plants in excellent health. The terrain is perhaps one of the few aspects to watch out for. It must be dissolved, well drained, rich in organic matter. The multiplication of the Delphinium occurs by seed at the end of the winter season or at the beginning of the spring one. For varieties of perennial type it is also possible to opt for multiplication by cutting or division. Periodically it is necessary to proceed with the pruning of the plant, in the sense that it is necessary to eliminate the dried or damaged flowers in order to avoid, as much as possible, that they turn into dangerous vectors of pests and diseases.

Ideal fertilization



As with any type of plant, even the Delphinium absolutely needs correct fertilization in order to grow healthy, guarantee a beautiful flowering and autoimmunize as much as possible against diseases or parasites. The ideal period in which to proceed with the fertilization of Delphinium is between March and September, using a fertilizer specifically designed for flowering plants. The frequency of the fertilizations must be an average of once every 10 days. In the hottest period it is almost mandatory to supplement with small amounts of mineral fertilizer. The doses to be administered are those indicated on the individual packages and it is highly recommended, for the well-being of the plant, to follow them to the letter, to avoid irreversible damage to the Delphinium.

Delphinium: Exposure and possible diseases



In the correct growth of a plant, exposure certainly plays a fundamental role. For the Delphinium, it should preferably be sunny even if the development of the plant is not prevented even in the semi-shaded areas. It is sufficient that the plants can enjoy direct sunlight at least for a few hours throughout the day. The absolute shelter from winds and currents is indispensable. The Delphinium plants, in fact, often develop very much in height, so excessively strong winds could represent a serious danger as it could break them. The Delphinium rarely happens to be infested with pests or diseases. Possible problems include aphids and snails (chemically treatable) and root rot.
