I have almost no problem planting in the fall. I find it so much easier than planting in the Spring. Less remembering to keep them watered. Don't get me wrong. I plant quite a bit in the spring. Actually, technically, I plant very end of Summer. I try not to plant anything after Sept 15th. But those plants seems to be so much better the next year. Sure I lose one or two. But I've lost more from Spring/Summer planting.
Mums however must be planted in the spring/very early summer.
Just my two cents.
