It will soon be time to plant these lovely flowers again. They are so adaptable - last year I bought too many (not unusual), so planted the spares in a box, where they stayed until March. I was able to fill in many gaps in the garden and the flowers produced were equally as good as those planted in October,
Am I right in planting them deep? I'm sure I've read that advice somewhere. Any other helpful hints? Do people nip out the tops when planting? Feed them?
