Growing conditions
Bearded Penstemon, like other members of the genus, cannot be called a whimsical culture. However, in order to achieve active flowering, it is important to adhere to the following conditions. It is recommended to plant the plants in well-lit areas, sheltered from the cold northerly winds. Soils are preferable loose, light, water and air permeable, drained, nutritious, with an acidic pH. Do not try to grow bearded penstemon on heavy clayey, waterlogged and saline soils. On heavy ones, cultivation is possible only if pebbles or coarse-grained river sand are introduced into the soil.
Breeding features
Bearded penstemon is propagated mainly by the seed method. The culture is grown in a seedling way. Sowing is carried out in the third decade of February - the first decade of March. Since the seeds are small, they are not buried in the substrate. And they only distribute it over the soil surface, sprinkle it with sand a little, pour it from a spray bottle and cover with film / glass. By the way, sowing is carried out in a sand-peat mixture. The seedling boxes are kept in a warm and well-lit room. The optimum air temperature is 20-24C.
With regular watering and airing, seedlings are formed already on the 10th day. Diving of seedlings into separate containers is carried out with the appearance of 2-3 true leaves on the plants. It is recommended to use peat pots for diving. Landing in open ground is carried out in the second or third decade of May; in the southern regions, disembarkation begins from the end of April. The optimum distance between plants is 25-30 cm.
Also, bearded penstemon is propagated in a vegetative way, namely by division. For the procedure, large bushes are selected, which are divided into several parts, and then transplanted to a new site at a distance of 35-40 cm from each other. Less often, bearded penstemon is propagated by cuttings. The procedure can be carried out throughout the summer. For these purposes, take the apical shoots, which are cut and put on rooting in a moist substrate. After rooting, the cuttings are transplanted to a permanent place.
Care features
The main procedures for caring for bearded penstemon are regular watering as the soil dries up, loosening and feeding. In early spring and before planting, the soil is fertilized with rotted manure, and during the summer, 2 more fertilizing with organic fertilizers is required. It is also recommended to apply phosphorus fertilizers at the time of flower formation. Regular removal of faded inflorescences is encouraged. This will allow you to maintain a high decorative effect for a longer period. In the fall, the aerial part is cut off, although some gardeners retain the foliage rosette.
