watering

Water Larkspurleaf Monkshood regularly throughout the growing season to ensure it has enough moisture. The best time to water it is early in the morning before temperatures start to rise, so the plant has plenty of time to absorb moisture. Water it until the soil is moist but not soggy, and drain away any excess water from the bottom of the planter. During the summer months in particular, you might need to water Larkspurleaf Monkshood every 3 to 4 days; however, if it rains, you should not water the plant at all.

sunlight

Larkspurleaf Monkshood (Aconitum delphiniifolium de) is a shade-loving plant that prefers dappled sunlight or light shade. It can tolerate full sunlight for a few hours in the early morning or late afternoon, provided that the temperature is not too hot. For optimal growth, it should receive at least 4-6 hours of direct or indirect sunlight per day, ideally during the morning hours when the light is not as powerful. During hottest times of the year, it should be kept in a location that receives only indirect natural light or diffused sunlight.

pruning

Pruning for Larkspurleaf Monkshood (Aconitum delphiniifolium de) should be done once a year during late winter or early spring. This should be done just as signs of new growth are appearing or just after flowering is complete. Start by removing any dead or dying branches, stems, or foliage. Then continue by thinning out overgrown areas of the plant. This can include cutting back long stems and removing crowded or tangled branches. Pruning should be done with clean cuts to avoid disease or pest issues. Once the pruning is complete, it is important to provide the plant with adequate nutrient and water supply for the growing season.
