It's surprisingly common to find decorative pots with only a single small hole, or sometimes none at all, particularly among pots bought primarily for their looks rather than their practicality. Without enough drainage, water has nowhere to go after rain or watering, and the compost around the roots can quickly become saturated and starved of oxygen. This oversight is particularly common with pots bought as gifts, where practicality was clearly not the main concern.
Before planting anything in a new pot, it's worth checking the base carefully and, where possible, drilling one or more additional holes using a masonry or ceramic bit suited to the material. Plastic pots are usually straightforward to modify, while glazed ceramic or terracotta needs a steadier hand and a slower approach to avoid cracking the material. Work slowly and let the drill do the work, rather than forcing it through brittle material.
Recognising the signs of poor drainage
A plant suffering from poor drainage often shows yellowing lower leaves, a persistently soggy surface even days after watering, or a slightly unpleasant smell coming from the compost itself. These signs are frequently mistaken for other problems, so it's always worth checking the state of the drainage before assuming something else is wrong. Roots that have turned brown and mushy when checked are a further, more serious warning sign.
If drilling extra holes isn't practical, using the pot purely as an outer cover for a properly drained inner pot is a reliable alternative, allowing excess water to be tipped away after each watering. This approach also makes it far easier to swap plants in and out without disturbing a decorative outer container.
Good drainage is one of the simplest things to get right in container gardening, yet it remains one of the most overlooked, especially when a pot is chosen mainly for its appearance. A few extra minutes spent checking drainage before planting can save a great deal of disappointment later in the season. Neighbours and friends who garden are often a good source of practical tips on this exact problem.
