The Skullcap should be preferably located in a place where it can have at least a few hours a day of direct solar light. Perennial plants mainly have a spring and summer development. During the coldest months of the year the aerial part can completely dry out, to come up the year after.These plants aren't afraid of the cold weather and can be grwon in the garden throughout the whole year.
The Skullcap has a panel-like development, therefore it tends to widen very much. This plant in the summer assumes a yellow colouring; it is small in size and can reach 10 cm high. It doesn't keep its leaves in the winter. These plants are used in rock gardens.
In the spring let’s fertilize perennials periodically, using a specific fertilizer for flowering plants, to add to the irrigating water, every 20-25 days; or we can spread a slow release fertilizer near the plants every 3-4 months.
Let's water abundantly, moistening the soil deeply with 2-3 glasses of water , but let's act only when the substratum is dry, leaving it dry even for 1-2 weeks before watering it. These plants display a pretty long period of vegetational rest. During this time it isn't necessary to water the plants.
As the day-time temperatures rise at the beginning of the spring, it is agreeable to practice a preventive treatment, with a wide-range insecticide, which should be applied when there aren’t flowerings in the garden. Before the buds become too large, it is advisable to also treat them with a wide-range fungicide, to prevent the development of fungal diseases which spread easily when there is an elevated environmental moisture.
Locate these plants in a soft and deep, very well drained soil.
If desired, we can grow the The Skullcap in a container. The indications given in this article are related to a medium size plant.
