Watering Plants

Before watering

Check below the surface with a finger, wooden probe, pot weight, or moisture reading. Confirm that the plant’s species, pot, temperature, and light justify watering.

Water thoroughly

Apply water slowly across the surface until the entire root ball is wet and excess leaves the drainage hole. Empty saucers after drainage.

Different plants, different drying

Most foliage plants are watered after the upper layer begins to dry. Cacti and many succulents need deeper drying. Newly planted outdoor plants need closer observation until roots extend into surrounding soil.

Recognize trouble

Constantly wet mix, odor, fungus gnats, translucent tissue, or a plant that wilts while wet suggests root stress. Crispy tissue, shrinking mix, and an unusually light pot suggest drought. Similar symptoms can have different causes, so inspect roots and mix before acting.

Water quality and hygiene

Use clean water near room temperature. Avoid repeatedly wetting crowns or leaves that remain cold and still. Clean tools and do not move runoff from a diseased plant to another pot.
