Tall Bugbane

Bicoloured Monkshood should be watered deeply about once a week in the spring and summer when the soil is dry. The soil should be kept consistently damp (but not soggy) during this time. In the fall and winter, water less frequently and only when the soil is completely dry. It's a good idea to water in the early morning or late evening to minimize evaporation and give the plant some time to absorb the moisture. Additionally, Monkshood plants should always be watered at the base, not on the foliage, to avoid leaf scorch.

Bicoloured Monkshood (Aconitum x cammarum) requires around 6-8 hours of sunlight every day. However, it can also thrive in partial shade, so it should be placed in an area that receives full sun in the morning, then shifting to a spot with some shade in the afternoon. The plant should not be placed in direct sun in the midday and late afternoon as it can cause damage and sunburn. It’s best suited for regions with mild winters and moderate temperatures.

Bicoloured Monkshood (Aconitum x cammarum) should be pruned in late winter or early spring if needed. When pruning, take care to not damage any new shoots coming from the base of the plant. If the foliage is dieing back in the center of the plant, you can make small cuts to just above the emerging shoots. This will help keep the plant shaped and promote new growth. Be sure to not cut off any healthy green foliage. Trim off any dead flower stems around the base of the plant. Doing this will help dormant buds from forming and help the plant look more attractive. With regular pruning, Bicoloured Monkshood can maintain its graceful shape and continue to look beautiful in your garden.
