Growing evening primrose in the garden

Planting evening primrose

A sunny area is best for growing a primrose, but it can also grow in a little shade.The composition of the soil for such a plant is unimportant, however, those areas that are swampy or excessively wet are not uniquely suitable for it. The fact is that it belongs to those plants that tolerate drought better than stagnant water in the soil. Evening primrose will grow best on light sandy soil with a pH of 5.5–7.0.

If you decide to decorate your plot with evening primrose, which is a biennial, then you can grow it through seedlings. In the last days of February or the first days of March, seeds are sown in seedling boxes filled with a suitable substrate. After the seedlings that have appeared grow up and get stronger, they are planted in open soil, while a distance of 0.5 to 0.6 meters must be maintained between the bushes. The seed can, if desired, be sown directly into open soil. Sowing is carried out in the last days of April or the first - in May, and you can do this before winter. Seeds are sown in moistened soil in 2 or 3 pieces, while they need to be buried into the ground by 5-10 millimeters. When sowing, you need to adhere to the 30x30 centimeters scheme. But first it is necessary to prepare the site, for this it is carried out by digging it to an average depth, at the same time fertilizers must be applied to the soil, for example, 3 kilograms of humus (compost) and 2 tbsp are taken per 1 square meter. Nitrofoski. After the appearance of seedlings, they need to be opened, keeping a distance of at least 10 centimeters between the bushes. Plants may need a few more thinning depending on the species and variety, as a result, each of the bushes should have a sufficient feeding area. During the first season, the formation of a basal leaf rosette and a root system is observed in perennial and biennial primrose, while flowers and peduncles grow only in the next year.

Evening primrose care in the garden

Young bushes are watered systematically once every 7 days until they are completely rooted. Adult plants need watering only during a prolonged dry period. When the plant is watered or it rains, it is imperative to loosen the soil surface around it while pulling out all the weeds.

If, during the preparation of the site for planting, all the necessary fertilizers were not added to it, then in the spring it will be necessary to carry out foliar feeding with a weak solution of a mullein. If all the necessary fertilizers were added to the soil, then the bushes will need to be fed during flowering by the root method and use a complex mineral fertilizer for this. During the flowering period, wilted flowers should be regularly removed from the bushes and this must be done, thanks to this, the flowering will be longer, while the evening primrose will not be able to reproduce by self-seeding.

In some species, the root system gives growth after growth. In order to limit the growth of roots, it is necessary to dig in sheets of metal or slate around the flower bed into the ground to a depth of about 25 centimeters. Enotera grows very quickly, therefore, at the first signs of degeneration, the plant must be removed from the soil, divided into several parts and planted in a new area. It is recommended to carry out this procedure at least once every 3 or 4 years. In the last days of the season, when the flowering is completely over, the two-year-old primrose must be dug up and burned, while the ground part of the perennials is only cut off.

Perennials do not need shelter for the winter. However, if, according to forecasters, the coming winter will be with little snow or frosty, the bushes in late autumn should be covered with compost or peat.
