Care Instructions
Lupinus polyphyllus thrives in areas with bright, direct sunlight and moderate temperatures. It prefers soil that dries out partially between waterings and benefits from moderate humidity. Regular watering and occasional pruning will help maintain its health and appearance.Soil
This plant prefers well-draining loamy soil with a slightly acidic to neutral pH. Good drainage is essential to prevent root rot. A mix of garden soil with compost can provide the necessary nutrients and structure.Fertilizer
Lupinus polyphyllus benefits from a balanced fertilizer with a nutrient composition of 5-10-10. Fertilize in early spring and again in mid-summer to support healthy growth and flowering.Repotting
Repotting is generally not necessary for Lupinus polyphyllus as it is typically grown outdoors. However, if grown in containers, repot every 2-3 years in early spring before new growth begins. Ensure the new pot has good drainage and fresh soil mix.Propagation
Propagation can be done through seeds or cuttings. Sow seeds in early spring or fall, and keep the soil moist until germination. Cuttings can be taken in late spring or early summer and rooted in a well-draining soil mix.Pruning
Pruning is beneficial for Lupinus polyphyllus to remove spent flower spikes and encourage new growth. Prune in late spring after the first bloom and again in late summer if necessary. Use clean, sharp tools to make clean cuts.Toxicity
Lupinus polyphyllus is generally non-toxic to pets and humans. However, some species of lupines can be toxic if ingested in large quantities, so it's best to keep pets and children from consuming any part of the plant.Additional
Lupinus polyphyllus can attract pollinators such as bees and butterflies, making it a great addition to a pollinator-friendly garden. It can also help improve soil fertility by fixing nitrogen, thanks to its association with nitrogen-fixing bacteria.REVOLUTIONIZE YOUR PLANT CARE
