The soil on the site must be fertile, loose, well permeable to water and air, and also have high acidity.
Where to plant Penstemon
For successful planting of penstemon, it is necessary to take into account its love for sunlight and a good drainage system in the soil.
Choose a sunny location with morning and afternoon sun and protection from the evening heat.
Planting is best done in spring or autumn, when the soil temperature reaches 10-12 degrees.
Care
Penstemon is extremely sensitive to the presence of oxygen at the roots, so soil care must be careful and regular.
The formation of a crust on the surface of the soil around the plant is not permissible, so after watering the soil is loosened.
To retain moisture in the soil and prevent overheating of the roots, mulch the surface after watering.
A layer of mulch on the surface of the soil around the plant also prevents the growth of weeds, which prevent Penstemon from developing.
Propagation by seeds
It is recommended to sow seeds in open ground in spring or autumn, after return frosts have passed.
Sow the seeds on a previously prepared area, while they are sprinkled with a not very thick layer of soil.
Seeds of some species must be stratified before sowing.
Watering and fertilizing
Penstemon needs regular watering so that the roots do not suffer from lack of moisture.
Nevertheless, stagnation of water at the roots is dangerous, as it causes them to rot.
The amount of watering is adjusted depending on the air temperature and the presence of precipitation.
An important event is feeding the plant.
