Is it too late to plant flowering vines? I live in zone 9. Which vines can I leave in pots and are good for full sun?
In most cases it is best to plant new vines in spring or fall.
You can plant now but will need to take extra care and precautions to keep the plant watered. New plants have little protection from heat and drying winds of summer.
Visit your local greenhouses and garden centers to see what is available in your growing area.
Verify the soil type that you have.
I have a climbing vine that I planted 2 or 3 years ago. It gets to be 8 to 10 feet tall. Last year it produced blue morning glory flowers, but this year it is producing purple clematis flowers. Why? Is it a hybrid? Thanks.
Even if your vine is a hybrid, it would not revert to a different species.
Perhaps you have 2 vines planted in the location.
Will they climb up my smooth, vertical fence (1/2" spacing) or should I add trellises?
