Hi Gerry – I have panseys, alyssum and dwarf sunflowers growing in pots and they are suffering with purple leaves and are generally unhealthy looking. Same thing with window boxes: instead of full healthy growth I have scraggly plants with purpling leaves. Erin Premium Compost with added John Innes used in all cases. Watering every 2-3 days. All in full sun. Any ideas?

These plants are starved of nutrients.
Most modern composts only have about 4 to 6 weeks plant food in them and liquid feeding is essential, every week or ten days, if slow-release fertilizer has not been added at planting time.
