Sunflowers Not Blooming
I bought sunflower seeds from B & Q to grow with my little granddaughter. I grew them on the window sill until they were established and planted them on in pots. I have a south-facing garden and the stems are now about 5-6 feet high, but although there is plenty of foliage, there are no buds. Can you give me any advice?

You may need to be patient, most varieties of sunflowers have a fairly long growth period before maturity. It depends on what variety you planted. I have 2 Maximillians in full bloom and other varieties haven't put out bloom yet.
Hope that helps,
