Agapanthus

How to water agapanthus

Agapanthus (Liliacee family) is a plant with a remarkable decorative effect, the result of its splendid flowers, with 5-8 cm long petals, collected at the end of the stems in very showy umbrella-shaped formations. Their colors, blue, lavender or white, in July, August and September create a fascinating contrast with the bright green of the long ribbon leaves. The main varieties grown in Italy are the evergreen African agapanthus , which reaches an average height of 70 cm (but can even reach one meter) and agapanthuspraecox, with blue flowers. Then there are the deciduous varieties, that is the most widespread agapanthus campanulate, with blue funnel-shaped flowers, or blue-lavender in the Isis variety, similar in height to the previous ones, and the agapanthus inapertus, with blue flowers. The watering of the agapanthus in the summer season must be generous and constant, both for potted plants and in the ground, but avoiding stagnation of water that would cause the roots to rot. In winter, however, the agapanthus must be watered with great moderation. Pay attention, however, that the leaves do not collapse, in which case it is necessary to intervene promptly by wetting it.

How to cultivate


To cultivate agapanthus in the correct way, you need to start with the choice of soil: fertile but well drained, the ideal is a mixture of universal soil for flowering plants, mixed with clayey soil. If you opt for planting in pots, you should know that the fleshy roots of this plant will tend to split it, so it is not advisable to place it in an expensive container. Another note to keep in mind is that agapanthus does not like repottings, flowering can also be affected. For this reason, in anticipation of growth, it is advisable to immediately choose a large pot. The cultivation of agapanthus must also provide for the care of the winter period. If the climate is mild it can be left outdoors, cutting the stems and mulching the pot or the ground, for example with straw. Otherwise it is advisable to shelter the plants indoors, as long as it is a cool environment. In fact, it is in the cold season that the agapanthus produces buds, and too high temperatures would be able to alter the flowering cycle. Multiplication is done in spring with seeds. Splitting the tufts of adult plants, on the other hand, can damage flowering.

Fertilization


The period of fertilization of the agapanthus must begin well before flowering, ie in spring, to provide the plant with all the nutritional elements it needs to produce its conspicuous inflorescences. The suitable fertilizer is the liquid one, for flowering plants. It must contain nitrogen, phosphorus, potassium, as well as small quantities of the trace elements zinc, iron, boron, manganese and copper; this is because agapanthus is a slightly acidophilic plant. This is particularly important if the water with which you are watering is very calcareous: calcium, in fact, hinders the absorption of some micronutrients, primarily iron. The frequency of agapanthus fertilization must be every 15 or even 20 days, and the fertilizer must be diluted in the water with which the plant is bathed.

Agapanthus: Exposure, diseases and remedies


The exposure of the agapanthus must follow that of the plant in its natural habitat, ie in full sun. Only in this way, in fact, will the plant be able to produce its abundant blooms. As far as agapanthus diseases are concerned, the good news is that it is a robust plant, rather resistant to attacks by insects and molds. The only enemies that can sometimes cause damage to this Liliacea, feeding on its leaves, are the snail and the snail. The infestation can be recognized by the typically chewed leaves. The remedy consists in manually eliminating snails and snails at dawn, when they are visible precisely because they are intent on feeding. It is difficult to use aggressive products such as snail killers if you intervene in time. Another problem, resulting from an excess of watering, consists in the rotting of the roots. In this case, irrigation must be stopped immediately.
