Irrigation, pruning and exposure of the gaura lindheimeri

The irrigation of the Gaura Lindheimeri should be concentrated above all in the summer period and must be sufficient to keep the soil moist but without soaking it. The plant fears water stagnation, therefore the quantity of water must not be exceeded and it must be ensured that there is not much of it left in the saucer. In winter, irrigation must be drastically reduced and must be limited only to prevent the soil from drying out excessively. The Gaura Lindheimeri loves the sun but also tolerates a partial shade exposure, and does not fear the cold, even if the temperatures are particularly rigid. Pruning should be carried out during the flowering period, to eliminate withered flowers, and at the beginning of winter. In the latter case, the plant should be pruned 20 cm from the ground.

Multiplication, soil and cultivation of the gaura

The Gaura Lindheimeri plant belongs to the species of rustic perennial plants. Its cultivation is extremely simple, whether it takes place in the ground or in pots, and the most suitable growing medium is that for flowering plants. Despite being a resistant plant, its root system rots easily, therefore the soil for planting must allow excellent water drainage. To this end, when the Gaura Lindheimeri is planted in the garden, it is advisable to mix river sand with the soil, while if it is cultivated in pots, a layer of expanded clay should be placed on the bottom of the same. The multiplication of the plant can take place both by seeds and by the division of the tufts, the flowering goes from May to October and the repotting must take place every 2 years.

Proper fertilization of the plant

The first fertilization of the Gaura Lindheimeri plant must take place in the planting phase, working the soil well with semi-mature manure. Subsequently, the plant needs support at the end of winter, using a slow-release fertilizer containing all the micro and macro elements necessary to strengthen Gaura Lindheimeri before flowering. in particular, the most suitable fertilizers for this plant are those rich in: nitrogen, potassium, phosphorus, calcium, magnesium and sulfur. The slow-release ternary granular fertilizer should be administered every 2/3 months. If you opt for liquid fertilizer, it is a good idea to choose it from the universal products for flowering plants and administer it every 2 weeks starting from the end of winter, diluting it in the watering water.

Gaura lindheimeri: Diseases, parasites and remedies

The Gaura Lindheimeri plant does not easily contract diseases, but it can suffer from root asphyxiation. In this case, it is necessary to intervene immediately by replacing the planting soil with compost worked with sand, in order to improve the flow of water. The rotten root tufts must be isolated and divided from the still healthy parts of the plant. The parasites that most frequently affect Gaura Lindheimeri are aphids that attack buds and flowers. These “little lice” must first be removed manually, after which the plant must be treated with a pesticide. A natural remedy against aphids can be achieved by dissolving Marseille soap flakes in hot water: this liquid, once cooled, must be sprayed over the whole plant.
