I bought a hosta today. It is my first time with it. I want to keep it in a pot. Should I transplant it now or do it by end of next month(fall)? I am in Seattle,WA(zone 7). Will it survive the winter? TIA!!
Here in zone 5, they're very forgiving plants, but i'd be reluctant to plant most things before it cools down a bit. I'd go ahead and wait a month, won't hurt.
I buy plants all through the season, and never hesitate to transplant. As long as it's in a pot, I go right ahead and plant it where I want it. The nursery pots are so small, the plants will get root bound quickly. The smaller pots also dry out fast, and I'm just too busy to keep checking the pots every day. Most hostas do well in containers, as long as they're large enough. I've had hosta cuttings in small pots during winter, and they came back fine in spring. I didn't leave them like that on purpose mind, I had put them behind some bushes, and by the time the frost came they were forgotten.
Are you asking if you can grow them? I think you can. There are about 200 different hostas growing in Australia. Some of the best ones are H. undulata-cultivars and the Fortunei-hostas. A chap called Robert Angus started growing hostas in Australia around 1980. In New Zealand Mr. Gordon Collier is a known hosta-grower. All according to my book. I don't know where in Australia you live, but if you check with Mr. Angus I'm sure he'll tell you more.
