Q: I ordered Sky's the Limit climbing rose. It will get about four hours of direct sun and six hours once the sun climbs higher. Will it survive in the winter? We are in the mountains, where it's colder.ANSWER: Sky's the Limit is a new rose for 2007, and it looks very good. It's rated hardy in zone 4, which is very cold, so you should have no problem in the mountains. You should follow the usual custom of winter protection for roses in that area, which probably means a deep mulch.In the summer, that rose needs six hours of direct sun each day for best blooming. If you can put it in a different spot than planned so that it gets the right amount of sun, do so. It grows 10 to 12 feet.

Q: I planted a row of dwarf Burford hollies before last summer. They were kept watered and given plant food through the drought. They looked really good with new growth until the early April freeze. Now the old leaves have fallen off many of them, and the new growth has died. Is there any way I can revive them and save the time and money I spent?ANSWER: The plants will revive, and you should see signs of new growth already. If you see tips of branches that have died, snip them off gently. Keep them watered through the summer, because the roots are still getting established. I think a seeper hose placed under the mulch would make it easier for you. Be sure to keep them well watered during dry weeks.

Q: Can I dig up only part of my peony for transplant now? I do not want to move the entire plant. It gets larger every year. I have new shoots that I would like to transplant. Is this possible?ANSWER: That's risky business. Trying to separate the plant while it is still in the ground is not something I would recommend, especially at this time of year. The best thing to do is wait until late summer or early autumn, then dig up the entire clump with its roots. Shake, then wash the soil off roots. Look at the clump carefully to find natural divisions. Use a knife to divide it, trying to get three or four buds for each new plant you are creating. Replant them very shallow; the top of the crown of roots should be at ground level.Time to sow Zinnia seedsWhile most people use bedding plants for their flower gardens, many still feel a yen to sow seeds. Why not try zinnias? They grow very quickly from seed to flower. Since the soil is now warm enough, you can plant the seeds where you want them to grow and bloom in the garden. They come in many heights, colors and shapes, but all require sun. Once seedlings emerge, thin to the distance suggested on the seed envelope. With care, transplant the ones you removed to a spot where they're needed.
