How to Grow and Care for Cuphea



Cuphea Hardiness Zones

Cuphea is a perennial in zones 10-12, but it is an annual everywhere else. This means that it will return each year in zones 10-12, but will not survive the winter in other zones.



How Much Sun Do Cuphea Need

Cuphea needs full sun to partial shade. They do best in bright, direct sunlight for at least 6 hours per day.

Cuphea can tolerate some afternoon shade, but too much shade will result in leggy growth and fewer flowers.

If you live in a hot climate, it’s best to plant cuphea in an area that receives morning sun and afternoon shade.



Cuphea Soil Requirements

Cuphea plants need well-drained soil that is kept moist. They will not do well in soils that are waterlogged or have poor drainage. Amend the soil with compost or peat moss to improve drainage if necessary.



Cuphea Soil pH

Cuphea plants grow well in a wide range of soil pH conditions. However, they prefer slightly acidic soil (pH 6.0-6.8). If your soil is too alkaline (pH >7.0), you can adjust the pH level by adding organic matter or sulfur to the soil.



Cuphea Plant Spacing

Cuphea plants should be spaced about 12 inches apart. If you want them to grow in denser clumps, you can space them closer together, but make sure to keep an eye on them so they don’t become crowded and start to compete for light and water.



Cuphea Temperature Requirements

Cuphea is a tropical plant, so it prefers warm temperatures and plenty of sunshine. It’s not frost-tolerant, so if you live in an area with cold winters, you’ll need to bring your plants indoors or grow them in containers that can be moved inside when the weather turns chilly.



Cuphea Fertilizer Requirements

Cuphea plants need an application of balanced fertilizer every few weeks during the growing season. A good 20-20-20 or 10-10-10 fertilizer will work well, and be sure to apply the fertilizer according to the package directions.



Cuphea Water Requirements

Cuphea plants are thirsty plants that appreciate frequent watering. Prolonged drought will reduce flowering, so make sure to keep the soil evenly moist.



Cuphea Humidity Requirements

Cuphea thrives in high humidity, making them ideal for humid climates. While they can tolerate lower humidity levels, they will typically flower less profusely in drier conditions.



Cuphea Pests

Cuphea is a tropical plant that is susceptible to various pests, including aphids, thrips, and whitefly. While these pests can be controlled with pesticides, it is best to avoid them altogether if possible. One way to do this is to plant Cuphea in an area where there are natural predators of these pests, such as ladybugs (for aphids) or parasitic wasps (for Thrips & whitefly).

Cuphea Diseases

Cuphea plants can be susceptible to Root-Knot Nematodes, which are tiny worms that live in the soil and feed on plant roots. This can lead to poor growth and stunted plants.

Root Rot is another common disease of cuphea plants, caused by a fungus that infects the roots. And when not properly prevented or treated the fungus will kill the plant’s roots, which will eventually cause the plant to die.
