Although
roses are grown in a fairly wide range
of conditions, there are a few factors that are common to almost all of them:
1. Full Sun - Roses do best in full sun and will
be o.k. as long as they get at least 6 hours per day. Those that do not get
enough sunlight may develop longer, weaker stems and flower less. More sun is also important in
that the heat will help dry the leaves of the roses and help minimize
black spot
disease.
2. Air Circulation - Again, to help minimize
fungal diseases, it helps to place roses where breezes can intermingle with the
plants. Planting them in an area of stagnant air will probably accelerate the
development of diseases.
3. Good Drainage - Like many plants, roses will
not tolerate having their roots routinely submerged in water for long periods.
This will lead to root rots and the decline and death of the plant. Heavy
clay
soils are a particular challenge in this respect.
4. Proper Soil - In addition to good drainage, it
is important to have a good supply of organic matter in the soil to help with
drainage and to hold nutrients. In sandy soils, the organic matter will help
hold enough water in the root zone. The pH (acidity) of the soil should be in
the range of 5.5 to 7.0 which is slightly acid. Since these are perennial plants
and will be in the same soil for many years, it is important to prepare the soil
properly before you plant. Have the soil tested and follow the
recommendations.
