Nurturing houseplants, so they flourish and thrive can be a profoundly rewarding experience. Whether you’re a seasoned houseplant expert or relatively new to the world of indoor greenery, keeping track of each plant’s individual needs and requirements can be tricky business. While some plants can be seemingly left to their own devices for days on end, others require constant attention and maintenance for optimal health.

Sufficient, regular watering is one of the critical aspects of houseplant care. After all, plants cannot survive without water; however, how much exactly depends on species and climate. Consider the following guide to watering so you can keep your houseplants happy and healthy.

When To Water

While every species has different watering requirements, as a rule of thumb, you should aim to water your plants once or twice a week in the spring and summer (growing season) and slightly less during the colder months. It is also advisable to water in the morning rather than the evening - this way, any excess water has the chance to evaporate over the course of the day.

Most houseplants will come with a label featuring watering schedule recommendations when purchased from a nursery or garden centre. However, online research may be required for more comprehensive instructions.

Signs Of Underwatering

The classic signs of an underwatered plant can be spotted by examining the leaves, which may droop, curl or wilt - this is because a lack of water causes plants to lose turgor, which is what makes living plant tissue rigid. You may also notice the soil is dry and has begun to pull away from the sides of the pot.

Fortunately, you can salvage an underwatered plant, provided the telltale signs are spotted early on. Start by trimming away any dead growth and place your plant in a sink or bucket of water until the pot is submerged. Leave it to soak for around half an hour, allow it to drain and keep it out of harsh sunlight until you spot signs of new growth.

Signs Of Overwatering

Overwatering can be equally detrimental to the health of your houseplants. The leaves of overwatered plants may be brown, yellow or limp. The base of your plant stems may also feel mushy, and you might even notice a rotten odour or mould beginning to form on top of the overly moist soil.

The best way to nurture an overwatered plant back to health by improving the drainage. Gently remove your plant from its pot and remove as much soil from around its roots as possible. After allowing it to dry overnight, you can trim away any dead roots and relocate your plant to a pot with drainage holes along with fresh potting soil.

How To Prevent Root Rot

Continuously overwatered plants are at risk of root rot, a condition which, if left untreated, will quickly kill plants. Root rot cannot be reversed, but you may be able to salvage your plants before this decaying disease completely takes hold. Still, prevention is better than cure.

While overwatering is the predominant cause of root rot, you can also prevent it by aerating the soil, allowing air, water and nutrients to penetrate the roots. You could also add clay pebbles to your potting mix to improve the soil’s draining properties.

Misting

Tropical houseplants enjoy environments with high humidity levels; hence, a Monstera is an ideal candidate for a hot, steamy bathroom. Misting is a highly effective method of boosting humidity for tropical plants whilst avoiding overwatering. Simply fill a spray bottle with tepid water and give your moisture-loving plants a good spritz several times a week or as needed. It is also advisable to keep tropical climate plants away from drafts, doorways and air conditioning units.

Solutions For Forgetful Waterers

If you’re a forgetful waterer, worry not - there is always a solution. The good news is that overwatering is generally considered more dangerous for plans than underwatering due to the risk of extensive root damage. It may be worth opting for low-maintenance plants that require less frequent watering. You could also try setting a watering alarm on your smartphone. Alternatively, you can purchase automatic plant watering globes, although this method is preferable for plants that require well-soaked soil.
