URBAN PLANTER BOXES

Choosing the correct size for an urban planter box is crucial for your plant's health and vitality. The key is to understand and accommodate the plant's root system. Start by researching your specific plant's mature root depth and spread. A general rule is to select a planter that is 1.5 to 2 times the width of the plant's root ball and provides enough depth for roots to grow downward without severe restriction. Deep-rooted vegetables like tomatoes or shrubs require boxes at least 12-24 inches deep, while herbs and lettuces may thrive in 6-8 inches. Always ensure the planter has adequate drainage holes to prevent waterlogged soil, which harms roots. Consider the material as well; porous materials like terracotta dry out faster than plastic or glazed ceramic. Ultimately, the right-sized planter gives roots room to expand, access to nutrients, and proper aeration, creating a strong foundation for a thriving urban garden.
