What your rose needs:
At least 6 hours of direct sunlight, more if you can.
Well drained soil or amended soil to provide drainage
Plenty of water
Don't forget your roses between the time you receive them and the time you plant them! Make sure they don't dry out. Don't forget to water them in well after they are planted. Newly planted roses are very vulnerable to heat and dry weather. Do not let them dry out.
Just after planting, treat your new rose as if it were still in the pot. It takes time for new roots to grow into the fresh soil of its new home. BalsamPath roses, when growing in their pots, are watered every day. After planting, water your new rose thoroughly every day for a couple of weeks, then cut back your watering to once every 3 to 4 days for a couple of weeks, and then water enough to equal 1 inch of rain, once a week.
If the mature width of your plant is 4 feet, then plant each plant 4 feet apart. That will give each plant at least 2-feet on either side of the plant's center for growth. That's enough room for each plant to grow to mature size. If you want a dense hedge, space the plants closer. If you want to see individual plant shapes, space the plants further apart.
Your rose will flower this year and for years to come. All the roses will flower abundantly in the spring. Then, some will stop blooming while others continue, more or less, for the rest of the season. After the flower is spent, it will try to form a "hip", the rose's seed pod. The rose will wait to throw off a new flowering stem until after the hip is formed. If you cut off, or "deadhead" the spent flowers, the rose will begin to form a new flowering stem right away. That way you get more roses to enjoy. If you want to collect the hips for tea or for the seeds, wait to deadhead until the hips are mature.
