Module 2 · Watering and light

How much water is enough?

By the end of this lesson you'll be able to tell a thirsty plant from a drowning one — and the two look surprisingly alike.

What we'll cover

Reading soil moisture by hand instead of by schedule
The three signs of overwatering people mistake for drought
Matching watering rhythm to light, pot size and season

Forget the weekly schedule

A calendar doesn't know how warm your room was last week or how much light hit the leaves. Soil does. Push a finger two inches into the pot: if it comes out clean and dry, water. If soil clings to your skin, wait.

Pots without drainage holes hold water at the bottom where you can't feel it. If you can't drill one, keep the plant in a nursery pot inside the decorative one.

This single habit prevents most of the root rot you'll ever see.

Where the water actually goes

Finger testing soil moisture — The top inch lies to you. The root zone holds moisture for days longer.

Three signs people misread

Drooping leaves. Thirsty leaves feel papery. Overwatered leaves droop while staying soft and heavy.
Yellowing. Drought yellows from the leaf edge inward. Too much water yellows whole lower leaves at once.
Crisp brown tips. Usually dry air or fertiliser salt build-up, not thirst.

When in doubt, check the soil rather than the leaves. Leaves describe the past week; soil describes today.

Try it on your own plant

Pick one plant you water on a schedule. For the next two weeks, don't water it until the finger test comes back dry, and note the date each time.

What to record

Days between watering, week one and week two
Where the pot sits and how much direct sun it gets
Anything that changed in the leaves

What you learned

Water on evidence, not on a calendar
Test two inches down, where the roots are
Drooping and yellowing describe both extremes — soil settles the question
