Penstemon barbatus - Beard tongue

continental : Plant which needs at least a few hours a day of solar rays.
Let's grow the The Penstemon barbatus in the garden; they aren't afraid of the cold weather.

alpine : These plants love very sunny positions, which are directly exposed to sunrays even for many hours a day.
During the summer months we can grow these plants outdoors without needing to protect them.

mediterranean : These plants can be placed in a very bright place, possibly sunny, directly under the solar rays for a few hours a day.
We suggest growing the The Penstemon barbatus in the garden, because they are rustic problems.

continental : The Penstemon barbatus needs very frequent watering; during this period of the year we advise watering even every 10-11 days using 1-2 buckets of water, trying to keep the substratum always slightly damp.

alpine : We advise frequent watering, every 10-11 days using 0-1 buckets of water, so that the soil is always a bit humid.

mediterranean : The watering must be very regular and frequent, using 2-3 buckets of water, so that the soil is always slightly damp, avoiding excesses and water stagnation. A good rule is to wet every 10-11 days.

Fertilize Penstemon barbatus : Usually fertilizers aren’t used during the summer; should we notice a development of spot virus on the leaves, caused by nutritional lacking, let’s add specific fertilizers. If we’re planting new shrubs, let’s always remember to add mature organic fertilizer, or slow release granular fertilizer.
