For urban gardeners, maximizing balcony space often means using planter boxes. A common question is whether these boxes need saucers or trays underneath them. The answer isn't a simple yes or no; it depends on your specific setup and priorities.
The primary purpose of a saucer is to catch excess water that drains from the pot after watering. This protects your balcony floor from stains, mineral deposits, and potential water damage. On wooden or composite decking, standing water can cause rot and decay. For apartments, it prevents water from dripping onto neighbors below, which is a crucial courtesy and often a lease requirement.
However, using a saucer has a significant downside: it can lead to overwatering. If the saucer is not emptied regularly, the planter box sits in water, which drowns the roots, promotes root rot, and creates a breeding ground for pests like mosquitoes. For plants that prefer dry conditions, saucers can be detrimental.
So, what's the best practice? A balanced approach is recommended. Using saucers is generally advisable for balcony planters to protect the structure and respect shared living spaces. The key is active management. Always empty the saucer 15-30 minutes after watering. For a more hands-off solution, consider "feet" or pot risers to elevate the planter box slightly, allowing air circulation and drainage without a pool of water. Alternatively, choose self-watering planters with built-in reservoirs that control water uptake.
In conclusion, while not always mandatory, saucers are a wise investment for balcony gardening. They act as an essential barrier against water damage. Your success lies in pairing the saucer with diligent care—watering thoroughly but ensuring no water remains stagnant. This simple step keeps your plants healthy and your balcony beautiful and damage-free.
