clematis

For optimal growth, Clematis 'Rooguchi' should be watered deeply every 7-10 days, depending on weather conditions and the type of soil. It is best to water in the morning so the foliage dries quickly and to prevent fungal diseases. In hot weather, water more often than usual. Generally, the plants should be kept evenly moist, but never soggy. Soil should be allowed to dry out slightly between waterings. During the winter, when the plants are dormant, water may not be necessary.

Clematis 'Rooguchi' is best grown in a location with full sun to partial shade, meaning it needs at least 6 hours of direct sunlight each day. It should be placed in an area with morning sun, and afternoon shade, or total shade with at least 4 hours of bright direct light. The rest of the day, it should be placed in a shaded or partially shaded area. Too much direct sun can cause the flowering to be reduced, and can also cause the stems to become sunburnt. It does best in cooler climates and needs to be protected from hard frosts.

Hardiness zone 4–8.

For pruning the Clematis 'Rooguchi' plant species, the best time to do so is in July/August. Prune the plant back to approximately 12 inches from the ground to promote new growth and reduce the risk of pests and disease. To shape and maintain the plant, prune again in late spring or early summer. On average, remove about 1-third of the plant’s growth. When pruning, always make sure there are at least 5 strong shoots, as inadequate pruning can reduce the flowering.
