Growth Conditions for Coreopsis Rueppellii Sch.Bip. var. Incisior Sherff

Coreopsis rueppellii Sch.Bip. var. incisior Sherff commonly known as Tickseed or Sand Coreopsis is a native plant to the southeastern region of United States. This plant requires specific growth conditions to thrive.

Light Requirements

Coreopsis rueppellii Sch.Bip. var. incisior Sherff prefers full sun exposure to partial shade. The plant needs at least six hours of direct sunlight to develop healthy foliage and bright flowers.

Soil Requirements

The plant prefers well-draining soil with a pH range of 6.5 to 7.5. Sandy and loamy soils are the best options for Coreopsis rueppellii Sch.Bip. var. incisior Sherff. This plant can tolerate drought conditions, but it cannot withstand water-logged or heavy soils as they cause root rot.

Temperature Requirements

The plant requires a warm climate to thrive. Coreopsis rueppellii Sch.Bip. var. incisior Sherff can tolerate extreme heat conditions of up to 100°F (37.8°C). However, it cannot survive in freezing temperatures, and the plant may die if the temperature drops below 50°F (10°C).

Fertilizer Requirements

Water Requirements

The plant requires moderate watering, especially during the hot and dry season. Water the plant when the topsoil is dry to the touch. Overwatering can cause root rot, while under-watering can cause the plant to dry up and die.

Cultivation Methods

The Coreopsis rueppellii Sch.Bip. var. incisior Sherff is easy to grow and is best suited for a sunny and dry spot in the garden. The plant prefers well-drained soil, and if the soil is too fertile, it might hinder its flowering ability. The plant can tolerate drought but cannot tolerate waterlogged soil.

Watering Needs

The plant requires minimal watering and can survive long periods of drought, making it perfect for those who have less time to water their plants. However, during the growth stage, the plant needs to be watered regularly to promote healthy growth.

It is best to fertilize the plants in the early spring before the plant starts to produce new growth.

Pruning

Deadheading is a common practice to promote continual blooming, which involves removing the spent flowers. Moreover, pruning can be done to control the shape and size of the plant, and it is best to do it in early spring before the new growth starts. Cut back the plant by approximately a third of its height to promote bushy growth and encourage more flowering.

Propagation of Coreopsis rueppellii Sch.Bip. var. incisior Sherff
