I need some advise on how to improve the condition of my geranium plants (I think its a Mavis Simpson). They have gone straggly as they have been trying to get to the light as the escallonia shrub growing behind them had got too bushy.
Should I cut the geraniums back to get them make more growth from the centre?
I have already cut off the dead flowerhead.
There are about four seperate clumps and a couple have some baby shoots.
