Planting & Care Tips

• Best For: Use for annuals like petunias or geraniums, perennials such as lavender or heuchera, or even small evergreens.
• Location: Place in full sun or partial shade depending on your chosen plants’ needs.
• Soil: Fill with a quality multi-purpose compost; add grit or stones at the base for improved drainage if planting species sensitive to waterlogging.
• Irrigation: Use the drainage plug to retain water during hot spells; remove it after heavy rain to prevent soggy roots.
• Seasonal Care: Clean and check the planter each spring before replanting; top up compost annually for optimal plant health.
