Why won't my snapdragons flower? They get plenty of sun. I grew them from seed. They are 6 inches tall.

You may try to feed the plant with some high potassium-based liquid fertiliser weekly to help encouraging flowering. Try 'Yates Thrive Roses & Flowers Natural Fish & Seaweed+ Concentrate' as a complete fertiliser to assist with healthy growth and prolific, beautiful flowers.
