Q.Sunflower too tall
I have a large border that contains a big area of annual sunflowers. In the past 5 years the flowers have become shriveled and do not open fully. They also grow far too high and I am five foot and they are easily a foot taller at their peak. I have 2 questions:
1. Can I stunt their growth a bit?
2. How do I get the flowers to bloom as they did?
The border was well established before I bought the house and there are far too many to dig up!!
Are they getting full sun and enough water (they need lots of water)? They are also heavy feeders. I would amend the soil with either compost, well-composted manure or fertilizer. I bet over time the sunflowers have depleted the nutrients from the soil they are growing in.
There really is no way to stunt the growth of a sunflower. You may want to consider pursuing sunflowers of a shorter variety.
