blue morn lobelia

My patches that I planted in full sun areas were great for quite a while. They now have grown to about 5 cm with lots of flowers, but tend to fall over and look a bit ‘how ya going.’ Should I trim them back by just snipping off the lot at about 2 cm, or what should I do?

Yes, trimming back should help. Also, make sure your plants aren’t getting too little water or staying wet too long (if soil is poorly drained). If they fall over when they haven’t been watered or rained on in a while, then perk up after watering, this is likely the problem. Also please see these articles:
