Nine houseplants that are genuinely hard to kill
"Hard to kill" usually means "tolerates being forgotten". That is the wrong test, because most houseplants do not die of being forgotten. They die of being fussed over.

How to read a drooping leaf
A drooping leaf is the least useful signal a plant gives you, because almost everything that can go wrong produces one. Thirsty droops. Drowning droops. Cold droops. Root-bound droops.

The temperature part matters more than people expect: warm air can hold far more vapour than cold air. So when cold outside air, already low... Read more...

The plant that died on your windowsill was, in all likelihood, watered too often by someone who cared. Roots need air as much as they need water A root is not a straw. It is a living tissue that breathes. Healthy potting mix is roughly half solid and half pore space, and those pores hold... Read more...
