How to cure passionflower

Water the passionflower

Passionflower is an evergreen and perennial sarmentosa plant native to Central and South America. Thanks to its beautiful flowers, it is very popular for ornamental purposes. It is also popularly called passion flower, just look at it in the summer season to understand why. The cultivated species are the passiflora edulis, with purple-white flowers and highly sought-after autumn fruits, the maracuja, the passiflora caerulea, with indigo blue and white flowers, and the violacea, with purple flowers. It is a plant that in the summer needs frequent and abundant watering, especially on particularly hot days, but at the same time care must be taken not to cause stagnation of water around the roots, which the plant is not able to tolerate. Watering must therefore be constant but taking care, during the operation, to stop before the soil appears too wet. In winter, water the passionflower in moderation only when it is sheltered indoors, or in case of prolonged drought.

Cultural care

Being a climber, when you decide to grow passionflower you must obviously provide it with a support, that is a backrest, an arch, a pergola, etc. The optimal substrate for this plant is a mixture of peat and clay, to which add even a small amount of sand to protect it from stagnant water. If grown in pots, the substrate must be completely renewed every other year. Furthermore, given that its root system tends to develop even in depth, it is good to take this into account when choosing the pot, opting for models of adequate height. To cultivate passion flower correctly, it is then necessary to provide a careful spring pruning, without which the plant would not produce its abundant blooms and would take on a disordered appearance. The multiplication can easily take place by seed or by apical cutting. Keep in mind that in the germination phase the plant is very afraid of low temperatures, so after sowing make sure that the environment is heated to at least 15 degrees.

Fertilize passionflower

Passionflower, even when grown in pots, turns out to be a robust plant with vigorous growth, accompanied by generous summer blooms. To succeed in this, however, she consumes abundant quantities of nutrients, which therefore must be provided regularly through fertilization. The best products are those suitable for flowering plants, with a high content of potassium and phosphorus, for example with a nitrogen-phosphorus-potassium ratio 5: 7: 7. Nitrogen, which is also important, must preferably be present in a lower concentration because it favors a greater development of leaves and branches to the detriment of flowering. To fertilize passionflower, the most suitable products are liquid ones, which must be administered before the beginning of flowering and for its entire duration, on a weekly basis.

How to cure passionflower: ideal exposure, diseases and remedies

Despite being a robust climber, passionflower fears, in addition to stagnation of water, frosts and a dim exposure. The latter would prevent them from flowering, while the intense cold can damage the root system. Therefore a correct exposure for the passionflower foresees full sun, possibly sheltered from the winds. An exception to this rule is Fr. caerulea, which also adapts to places where winters are severe, although this can cost it the loss of leaves in the cold season. The possible diseases of passionflower can result from incorrect cultivation, and in this case they manifest themselves with crumpled or falling leaves (index of excessive drought), or yellowed (too many irrigations). Other possible problems can arise from attacks of mealybug, spider mite or lice. Being insects, the remedy for infestation already underway consists in the use of broad-spectrum spray insecticides. Unfortunately, flowering could be affected, so it is advisable to act preventively with natural remedies; for example, you can sprinkle the plant with a concentrated infusion of strong tea.
