watering
Water your comfrey (Symphyyum uplandicum 'Variegatum') once a week or when the top 2-3 inches of soil feels dry. During the hotter summer months, make sure you provide more frequent waterings. Always check the moisture of the soil before watering to prevent the possibility of over-watering or root-rot. This plant species typically prefers moderately moist soils, so make sure not to let it sit in soggy soils for extended periods of time.
sunlight
Comfrey (Symphytum uplandicum 'Variegatum') is a shade-tolerant plant, but it needs at least 4-5 hours of direct sunlight every day for optimal growth. In regions with hot summers, it is best to provide full sun during the morning and partial shade in the afternoon. If grown in a flat or basket, it should be turned so that all of the leaves receive equal exposure to sunlight. During the winter, the amount of sunlight needed will be reduced significantly and the plant may even tolerate some light shade.
pruning
Comfrey (Symphytum uplandicum 'Variegatum') should be lightly pruned in early summer, after it blooms. Cut only 1 third to 1 half of the top growth back to encourage bushier growth. Remove the older, woodier stems completely for the best appearance. Prune only as much as necessary, since comfrey regenerates very quickly.
