Can cast iron outdoor tree boxes be retrofitted with drainage attachments?
Cast iron outdoor tree boxes are durable and stylish, but proper drainage is essential for plant health. Fortunately, these boxes can often be retrofitted with drainage attachments. Drilling holes in the base and adding a gravel layer can improve water flow. Alternatively, specialized drainage kits designed for metal planters can be installed. Always ensure the cast iron is treated to prevent rust. Proper drainage prevents root rot and extends the lifespan of both the planter and the plants. Consult a professional if unsure about modifying heavy cast iron boxes.
