    Yes, planting your roses is the surest way to see them survive winter. As always, amend the soil prior to planting. Dig a hole 3 times wider than the pot and only as deep as the rose itself. Gently heel in the soil as you back fill and water well. The crown must be just above soil level. Use 3-4 inches of mulch. Many feeder roots are severed when plants are dug up; it can't be helped. So the rose counts on you to keep the soil moist all the way until the ground freezes when rain is insufficient. It doesn't take much water as temps cool but dry soil going into winter can lead to winter kill. If you have a shredding mower, pile some chopped leaves over the crown once cold weather has settled in.

    Yes it will dominate and shade the foliage of the rose, preventing sunlight and photosynthesis for nourishment of the rose.

    If the roses bloom only once, in spring, then you have rambler roses. If they have large blossoms throughout the growing season, then you may have grandiflora roses. It is important to know the type of rose as pruning technics vary with rose types. With their large canes, grandifloras can be whipped around by winter winds. This can cause the base to be rocked out of the ground. Many rosarians recommend cutting the large canes back by half once the rose is dormant. Some suggest loosely tying the canes together with twine to prevent breakage if they are exposed to strong winds and/or heavy snow. Spring prune before leaves appear to remove weak and thin canes and tips that suffered winter die-back. There should only be 5-7 major canes to prevent crowding. An open structure allows better air flow and sun penetration and leads to a healthier rose. Remove the oldest canes down to the plant base. In cold winter climates, cover the base and surrounding soil with 3-5 inches of mulch. This is best applied after the ground freezes. Mulch helps keep it frozen and thereby reduces the number of freeze and thaw cycles that are detrimental to winter survival.

    re: leaflets on rose canes. If your rose is grafted with multiflora rose roots, rootstock canes may have 7+ leaflets. But there are many roses that normally have 7 leaflets. The best way to tell if you have a blind shoot from rootstock is to look at where it originates. If it is clearly from the base of the rose, it is a good cane. However, if you need to brush soil away to see where a cane originates, you have a blind shoot. These should be broken off below the soil line, not pruned off. I apologize that I forgot to address this question with my first answer.

    Roses sure don't like hot weather. Up until mid-October is the last fertilization for California. Follow instructions on your rose food. Fall fertilization should be low in nitrogen or have zero nitrogen. This helps the plant prepare for winter. Other writers suggest using regular rose food at half the rate in early fall. Remember that 2 inches of water weekly may be necessary in hot weather.

    Rose seeds need 10-12 weeks (or 6-10 depending on your source) at 40 degrees or colder before they will germinate. Here are two links for preparing seed and growing roses from seed.
