Light and Watering

A move, a new curtain, or seasonal change can alter both growth and how quickly a pot dries. Check the new conditions before repeating the previous watering interval.

Useful checks and guides

Low light vs too much lightCompare new growth with exposed-leaf damage.When to waterUse moisture, pot weight, and plant type.Potting mix and drainageChoose a pot and medium that let the root zone function.Light calculatorEstimate a placement from your room and window.

Where to start

Compare the same plant over time

A slower-drying pot is useful evidence of a change, not a universal deadline for watering. Temperature, roots, pot size, and mix also affect drying.

What it could be

Weak new growth

What you may see: Longer spaces between leaves and smaller new leaves appear in a dim position.

Next check: Move toward brighter light suited to that plant or add a grow light.

Sudden exposure damage

What you may see: Bleaching or dry tan patches follow stronger direct sun.

Next check: Shade leaves promptly from sun that is causing injury. If increasing sun exposure later, do it gradually. Window direction alone does not capture shading, season, or hemisphere.

Water runs straight through

What you may see: Runoff appears quickly while the center stays dry.

Next check: Water slowly and check the root-ball center. Root crowding or water-repellent mix may need correcting.
