When and how much to water

Bluebells are a genus of perennial, annual or biennial plants with a characteristic bell shape. Overall, the species are more than three hundred, some of which reach a few centimeters in height and others exceed 2 meters. Some species are native to Asia Minor, others European and those cultivated are about 30. The characteristic bell-shaped flower can be of different colors, purple, yellow, blue, red, white or pink. Usually the bellflower is used as a border flower in the garden or as a ground cover plant in rocky areas. From the point of view of watering, it does not require particular attention and should be irrigated every two weeks, unless the weather conditions are particularly hot and dry. Certainly, the slightly arid soil is preferable rather than too soaked and, if you want a particularly luxuriant flowering, a little fertilizer is essential. The bellflower grows well in any type of soil, as long as it is well drained because it does not like stagnant water. If you want to cultivate it in pots, it is not advisable for water to remain in the saucer: the soil must be moist, but not soaked.

How to take care of it

The bellflower does not need special care to vegetate quietly, a little nutritional supplement during the flowering period will allow the flowers to remain luxuriant longer and, if you want to be sure that the water does not rot the roots, it is appropriate add gravel or expanded clay to the soil. The ideal soil is that for flowering plants, carefully avoiding compounds that are too acidic and full of peat. Bluebells are plants considered rustic and are not afraid of the cold or adverse weather conditions. They are plants that quietly vegetate on their own simply with the rain, unless there are particular drought conditions. The numerous species of bluebells are bought ready in small plants to be repotted and can be propagated by division or with seeds. To germinate, the seeds must be placed in autumn on a cotton wool carpet at a constant temperature of 12 degrees; propagation by division is just as simple, just cut a piece of plant near a node and insert it in a fertile and moist soil.

When to fertilize

The bellflower must be fertilized regularly if you want to get lush blooms, although it is a rustic plant and does not need particular conditions to vegetate freely. Whether grown in the garden or in pots, the bellflower needs constant fertilization, both during growth and during flowering. In particular, fertilizer for flowering plants should be administered every 15 days and a fertilizer that contains little potassium and a high nitrogen content is preferable; this will favor the development of many flowers rather than green leaves and branches. When the plant is in the open ground in the garden it is advisable to fertilize every two or three months with a specific product for flowering plants, increasing the frequency from March to October. For potted plants it is better to administer more frequently, even once a week during the flowering period, a fertilizer diluted with water. There are also slow-release granular fertilizers on the market that must be used exclusively during the vegetative period. The bellflower should not be pruned, but to make it grow more luxuriant it is advisable to clean it in spring and autumn from dried leaves and flowers.

Campanula: Exposure and possible diseases

The bellflower prefers a partial shade position and it would be perfect if it had sun in the morning and shade in the afternoon. Some species do well in full shade and others in full sun, it depends on the type, and it is advisable to inquire at the nursery where we will buy our plant. Flowering is quite slow, but when they bloom they resist fungi and parasites well. To fight the aphids you need the appropriate insecticides, in the same way as the snails, which are frequent in spring and autumn. The most common disease of bluebells is leaf rust which must be fought by limiting irrigation and fertilization. At the end of winter and early spring, the bluebells should be pruned to allow the new shoots to grow and limit the development of mold. When the leaves dry up and the buds wither it means that the irrigations are insufficient, vice versa, when the plant does not bloom, it means that they are excessive. Yellow, mottled brown and crumpled leaves are a clear symptom of pests, especially the red spider, which is fought with a suitable insecticide.
