Cultivate still less (4)

I believe the answer is:

till

I'm a little stuck... Click here to teach me more about this clue!

'cultivate' is the definition.
(I've seen this before)

'still less' is the wordplay.
'TILL' is hidden in amongst the letters.
However, I am uncertain how the hidden word is indicated.

Can you help me to learn more?

(Other definitions for till that I've seen before include "Container for money" , "store for money" , "cash container" , "Cash machine" , "Work the soil" .)
