I live in Massachusetts, growing zone 6a. Yesterday my husband was given some young Rose of Sharon plants from a friend at work, grown from seed by someone else. I've always wanted some, and would like to know how best to ensure successful growth. There are six seedlings, ranging in height from 7" to 12", in a 9" by 9" plastic pot filled with dense wet soil, which looks to me like garden dirt.
Can I transplant them now? I've been told this is the worst time of year to do that. Our temperatures are between eighty and ninety degrees F during the day, sometimes hotter, down to the sixties at night, and it's quite humid.
How should I care for them while they're in the pot? As you can see, the stems are bending. Is staking a good idea, or would that disturb the roots? Should the pot be in the sun or shade, and what's the proper amount of water? If it's too soon for planting in the ground, do they need separate containers, or are they okay together?
Finally, how much distance will they need between them, or other plants, in their permanent spot? I have a section of day lilies, some of which I'm planning to remove to make a home for the Rose of Sharon.
Edit to provide requested information: The variety is Hibiscus syriacus. The parent plant is full and bushy, with single purple flowers. It's six years old and just over six feet tall.
