Care

Watering

Water regularly after planting, especially during dry periods. Once established, wahoo tolerates drought well. Avoid excessive moisture, which encourages fungal diseases. In summer, reduce watering if rainfall is sufficient.

Exposure

Plant your wahoo in full sun or partial shade for optimal growth. It tolerates partial shade, but fruiting and color are better in full light. Prefer a location sheltered from strong winds.

Pruning and shaping

Prune after flowering or in late winter to maintain a dense form. Remove dead wood and weak branches. Light pruning is generally sufficient; the plant naturally has an attractive shape. You can train it as a freestanding shrub or in a geometric form according to your preferences.

Soil and planting

Prepare a spacious planting hole in well-drained soil enriched with mature compost. Wahoo appreciates neutral to chalky soils. No major amendment needed; good initial preparation is sufficient. Lightly mulch after planting to retain moisture.

Fertilizer and nutrition

Apply balanced fertilizer in spring after bud break. No need for intensive fertilization if soil is fertile. An application of compost on the surface each fall maintains soil structure and supplements natural nutrition.

Diseases and pests

American wahoo is generally robust. Watch for powdery mildew in humid conditions (spray carefully or improve air circulation). Scale insects may occasionally appear; treat with neem oil if necessary. Good drainage prevents most health problems.

Did you know?

American wahoo produces striking pink fruit capsules in autumn that open to reveal seeds adorned with bright orange arils. This spectacular winter display inspired the English name 'hearts a-bushin' with love.' This plant was traditionally used by Native Americans for medicinal purposes, though its active compounds require respectful handling.

Where to buy it

Best planted in autumn so the roots settle in before summer, or in early spring once the frost has passed. Pick a plant with healthy foliage and roots that are not exposed. Best time: March, October, November.
