please help! baby peony questions
So I recently purchased a tiny baby Majorcan peony that arrived in a 4 inch pot. After letting it slowly adjusting to some sun I planted it in the ground. My reasoning at the time was that anything I grow in pots besides my plumerias just died! So this might have a better chance of surviving if planted in the ground. But the poor thing is sooo tiny, about 3-4 inches from the soil line. It's in an area w/ full sun but for now I have a taller plumeria sheltering it so it only get filtered sun. Also I wasn't sure if I was supposed to press the soil down because after a week some of the compost/soil has washed away and now part of the roots are showing? Should I bury the thing more?
I have really awful clay soil so I dug up a small hole and added 50% compost before I planted it. Of course now I'm second guessing myself. Maybe I should have dug a bigger and deeper hole? Maybe I should have planted it in a 5 gal for the first few years? Then I read that Peonies don't like to be disturbed so I'm all freaked out that I will kill it if I leave it in the ground and I will kill it if I pull it out and put it in a pot!
So what should I do now? Leave it in the ground or repot it in a 5 Gal??? If so what soil should I use? Also can I fertilize it yet or no? I'm losing sleep over this stinker! Sigh...
Thank you so much!!
