Here are tips on how to care for the blanket flower properly:

Light Requirement

The blanket flower thrives best in full sun. The plant can tolerate partial shade, but the color of the foliage will be less vibrant than it would in full sun.


The blanket flower is a drought-tolerant plant and can tolerate periods of light with moderate watering. The plant does best when the soil is kept evenly moist but not soaking wet. Over-watering can lead to rot on the foliage, especially if the soil becomes overly soggy.


The blanket flower is an evergreen perennial, so it will not die back in the winter. You can prune the plant to keep it tidy and healthy. Simply remove dead leaves and branches to maintain a neat appearance in your garden.


Blanket flower prefers poor soil. Therefore, you should avoid using rich matter or over-fertilizing the plant. Also, the soil should be well-drained, and it should be kept a little moist. The blanket flower may wither and dry off if the soil becomes overly dry.


The blanket flower needs very little fertilizer to thrive. A slow-release fertilizer with a balanced formula that includes essential elements such as nitrogen, phosphorus,, and potassium will work well for this plant.

Temperature and Humidity

Blanket flowers thrive in full sun. They can tolerate high temperatures between 15 and 30 degrees F. Keeping the humidity level in check can also make a difference in how well the blanket flower does in your garden. This plant does not require a humid environment and thrives in a hot, dry climate. In cooler climates, you need to protect your blanket flowers with a layer of mulch.

Pest Control

Blanket flowers can be susceptible to pests such as aphids, mealybugs, and spider mites. These pests can be controlled by using insecticidal soap or horticultural oil regularly.

Mulching Blanket Flower

You can protect your blanket flower from direct sunlight by adding a layer of mulch. Mulch will reduce evaporation from plants, which will help protect the plant from getting sunburned. You can use a layer of dry grass, leaves, or compost to create this mulch.
