Watering you plants? STOP! Water the...

SOIL!!
Image on the right? NO NO NO! This is such an inefficient way to give your plants the drink they probably desperately need right now..
Plants take in 95% of their water form the SOIL. They are wilting because the SOIL is dry.. so.. Water the SOIL!
Most of the water applied as shown opposite will likely evaporate before it can be absorbedf Plus, you risk scorching delicate leaves in strong sunlight. It also usually flattens small plants too, watering them in this way, so all round, a pretty nil-point approach to hydration.

ALSO, remember that the roots (where the plants draw their water from..) are not just around the base of the plant. In fact, better to water away from the base, around the peripheries where the edge of the root system will be seeking out H2O.

As if to prove the point - BASIL; Supermarket Basil always dying on you?
Stand the pot in a saucer; water in the saucer (basically, directly at the roots) Don't water from the top (other than the occasional dribble to keep the soil edges from shrinking). It'll last for months and months and months and...

Pesto recipe anyone?

What's wrong with this picture..?

Happy Basil
