Question
Can I divide my Euonymous and grow the division in a pot, under a shaded outdoor patio, year-round? If so, can you give me instructions re: the division?

Answer
Where are you located? To my knowledge Euonymous can be transplanted in the ground at any time of the year until the ground feezes. You don't have to use pots for any reason unless you just want them in pots. There are many varieties of Euonymous. Shrub form and ground cover forms are easily transpalnted directly into pots or the ground at any time of the year unless of course the ground is frozen.
