If you've forgotten to add fertiliser when planting, push a few plant food tablets between the plants into the soil to around finger depth. Snip off the dead heads of flowering plants at regular intervals to promote new flowers- Liquid feeding once a week will also keep your plants looking healthy and flowering longer. Greenfly and blackfly can be controlled with sprays.
