Do i need this all the time or can i use something else like maby add more perlite. Running out of gravel.
you dont really need gravel/rocks at the bottom of your pots.try vermiculite,perilite,peat moss.these will make for an easier root growth and a good drainage.its also cleaner and fairly cheap.
drain holes are a must. and i put parts of old clay pots at the bottom of my flowering pots. doesnt hurt and can help.
