What Is the Ideal Temperature Range for Trumpet creeper?

Ideal Temperature: 65 ~ 85℉

Campsis radicans, commonly known as trumpet vine, prefers warm temperatures for optimal growth. An ideal temperature range of 65°F to 85°F helps facilitate vigorous growth and blooming. These temperatures mimic its natural habitat, providing conditions conducive to robust root and foliage development.

What Soil is Best for Trumpet creeper?

Soil type: Loam, Sandy loam

Soil PH: 6 ~ 8

Campsis radicans thrives in well-drained soil as it prevents root rot by allowing excess water to escape efficiently. This reduces the risk of disease and ensures healthy growth. Rich soils provide essential nutrients like nitrogen, phosphorus, and potassium. Campsis radicans benefits from these nutrients with robust foliage and vibrant flowers. The soil should retain enough moisture to support the vine's rapid growth without becoming waterlogged. Consistent moisture aids in the development of strong roots and foliage.

How to Fertilize Trumpet creeper?

Fertilizer type: Balanced

For Campsis radicans, use a balanced liquid fertilizer at half strength to provide essential nutrients without overwhelming the plant. Apply approximately 1/2 cup of liquid fertilizer solution per square foot of soil. Ensure thorough watering before and after fertilization for optimal absorption.

How to Prune Trumpet creeper?

Pruning Time: Spring, Summer, Autumn, Winter

Ensure your pruning shears are sharp and clean to make precise cuts without causing damage to the plant. Sharp tools ensure clean cuts and reduce the stress on the plant, promoting quicker healing and reducing infection risks. Campsis radicans can ooze sap when cut, which might be irritating to the skin. It’s advisable to wear gloves and use a tarp underneath to catch the dripping sap, thus keeping your pruning area clean and reducing potential irritation. Post-pruning, always clear away the trimmed plant material and fallen leaves. This helps prevent disease buildup and pest infestation while keeping the garden area tidy and reducing problems associated with decay.

How to Propagate Trumpet creeper plant?

Propagate Time: Spring, Late Spring, Early Summer

Collect seeds from mature pods in late autumn. Allow the pods to dry and crack open, then extract the seeds, which should be stored in a cool and dry place until spring.

Select healthy, semi-hardwood stems in late spring or early summer. Cut 6-10 inches long sections, removing the lower leaves to prepare them for rooting.

Bend a low-growing stem to the ground in early summer. Remove a small section of bark, cover it with soil to promote root growth, and secure it with a peg or rock.

How to Repot Trumpet creeper plant?

Repotting frequency: Every 2-3 years

For Campsis radicans, the ideal time to repot is when you notice roots emerging from the drainage holes and the plant showing stunted growth or wilting despite regular watering. Typically, the best season is early to mid-spring when the plant awakens from dormancy and prepares for vigorous growth.

Select a pot that is approximately 2 inches larger in diameter than the current one. Ensure it has ample drainage holes to prevent water retention. Opting for a breathable material like terracotta can also aid in oxygenating the roots, promoting healthier growth and preventing root rot.

A well-draining potting mix composed predominantly of loamy soil is ideal. This soil mix provides the necessary balance of moisture retention and aeration, which is crucial for Campsis radicans to thrive. Adding some perlite or sand can further enhance drainage, preventing waterlogging.
