There are hints of summer in the air.
Some rain is possible.
Plants are putting on new growth at amazing speed. Insect pests and garden diseases thrive also, but prompt action can place you in control. It is too late to set out bare root plants in the area, However, plants in containers and those balled and burlapped can be set out now if there is ample soil moisture. If you have not already done so, set out ageratum, asters, petunias and marigolds this month. Toward the end of May it is time to sow seeds of biennials such as sweet william, pansy, wallflower, hollyhock, foxglove and Canterbury bells.
