Pentas Care Guide

Here’s everything you need to know to successfully grow and care for Pentas in your garden:

Planting

Plant Pentas in the spring, in well-draining soil that is rich in nutrients.
Dig a hole about 12 inches deep and space the plants 12 to 24 inches apart.
Pentas can also be grown in containers, which is ideal for creating clusters of plants for a stunning display.

Light

Pentas prefer full sun conditions but can tolerate partial shade.
Ensure they receive at least six hours of sunlight daily for optimal flowering.

Soil

Pentas thrive in rich, well-draining soil with a neutral pH level.
If your soil is too acidic, consider adding dolomitic lime to raise the pH closer to neutral.

Water

Water newly planted Pentas regularly until they are established.
Once established, they are moderate drought-resistant but may need additional watering during dry spells.
Water at the base of the plant to prevent fungal diseases, especially in humid climates.

Temperature and Humidity

Pentas prefer hot temperatures and high humidity levels.
They are hardy in USDA Zones 10-11.

Fertilizer

Use a well-balanced fertilizer, like 5-5-5, during the growing season to promote foliage and flower production.
Apply liquid fertilizer every four to six weeks in spring and summer.
