Rose gardening begins with either bare-root or potted roses that may be planted out into the garden. While roses may be successfully grown in every climate zone in the United States, knowing your climate zone and planting rose bushes at the right time will increase the chances of successfully getting the rose bushes off to a great start.
Roses in Various Climate Zones
Knowing your climate zone, and when to expect temperature variations, is imperative for successfully timing the planting of rose bushes. First of all, select rose varieties that will thrive in your climate zone; at least some varieties of roses may be successfully grown in all climate zones in the United States, and in much of the world. Roses will go dormant during the winter in cold winter areas. In zones with very hot summers, the roses will rest during the hottest part of the season, displaying smaller and fewer blooms.
Planting Bare-root or Potted Plants
Bare-root are selected rose varieties that are grafted onto a sturdy rootstock. These are best planted before their new growth develops, giving them plenty of time to put on foliage and flowers the first season. This will be in the early spring in most USDA climate zones. Potted rosebushes may be grafted, or may be growing on their own roots. Either way, they will have begun leafing out. You may plant these at any time during the growing season.
Watch the Weather
Avoid planting a rose bush during the extreme heat of summer in very hot weather climates. If you must plant them during the hottest part of the season, provide temporary shading and plenty of water. In the very early spring in colder climates, late frosts may nip the new growth of roses. Be assured that newly planted roses are developing a strong root system, and they will recover to perhaps even bloom the first season. You may cover the newly planted bushes on evenings before predicted frosts.
Roses planted at the proper time have a good chance of producing at least some blossoms during their first season. Roses thrive in a moist, well-drained soil. Take note during the first season how much water will keep the newly planted bushes moist. Though preferring a slightly acid PH, roses tolerate a wide range of soils and conditions. Properly plant the rose bushes at the right time, water and feed them throughout the growing season, and you will enjoy them for many years.
