Question by dfgquilter

HI, I have trouble with my cannas getting rotten. I understand we are to put them out in April, NOT MAY. Its so rainy now. They are in pots with drain holes.
Should I wait and keep them in the garage ( and let them sprout there) until May and more of the rainy season is over?
Please help.
Thanks, Dorian

Setting your cannas out in April is just general advice. If the weather is cold and the soil is soggy, they will rot (as you have discovered). You can set them out in May when things warm up and the soil drains away the excess moisture. If your cannas are rotting, you may want to take some time to amend the soil with organic matter to help it drain faster, or you can grow your cannas in containers where you can control the amount of moisture your plants get. Use regular potting soil and water when the top of the soil begins to dry out. You can set your cannas outdoors if they are planted in containers. Just place them under an eave or other covering on those days when spring rains heavy. Being outdoors will help them break dormancy and begin to grow so that when the weather settles, they can be moved to sunny spots. Best wishes with your cannas.
