The basics, distilled

Four habits that save most houseplants

01

Feel before you water

Push a finger two knuckles into the soil. Dry? Water. Damp? Wait. Most 'dead' plants are actually drowned.

02

Read your light honestly

Hold your hand a foot above the plant at noon. A crisp shadow means bright. A soft blur means medium. No shadow means too dark.

03

Rotate a quarter-turn weekly

Plants lean toward light. A small turn each time you water keeps growth even and stems straight.

04

Repot in spring, not winter

Roots want to grow when the days lengthen. Repotting in December is a slow way to stress a healthy plant.

Questions we get

Frequently asked

Do I really need to mist my plants?+

For most houseplants, no. Misting raises humidity for about 15 minutes, then evaporates. A pebble tray, a humidifier, or grouping plants together works far better if humidity is the actual issue.

Is tap water safe for houseplants?+

Usually yes. If your tap is heavily chlorinated, let a jug sit uncovered overnight before watering. Softened water is the exception — the sodium can build up in soil over time.

How do I know when to repot?+

Roots circling the drainage hole, water running straight through, or the plant drying out within a day or two of watering. Size up by one pot diameter — never jump from a 4-inch to a 10-inch pot.

Why are the leaves yellow?+

Nine times out of ten: overwatering. Feel the soil before you assume it's thirst. Our diagnosis guide walks through the other one time.
