You can not go wrong with either of these wonderful Texas shrub Roses. A great choice for Houston landscapes. They thrive in moist, well drained soil that consist of high amounts of organic matter (Compost). These conditions will develop a strong plant with an amazing amount of blooms.
Things you want to remember:
* Water in the mornings, not at night. This will help to avoid mold or fungus problems.
* Make sure the roots get watered not the foliage. If you have a sprinkler system, adjust the heads to spray low not too high.
* Use organic fertilizers rather than synthetic fertilizers. This will promote a more compact, dense and stronger plant. Synthetic fertilizers will just force the blooms instead of creating a overall healthy plant. You can even add a layer of pine needles around the roots to add some acid to the soil and roses. Azaleas, Camellias, Gardenias and Roses all really like a bit of acid in the soil. Therefore, are all good to plant together.
* These roses are much less susceptible to getting Black Spot, a fungus common in roses. If Black Spot does occur in these roses, simply cut off the infected stem, make sure to remove any other fallen leaves and discard them. In a spray bottle, add a combination of liquid Sulphur and fungicidal soap, then spray the infected rose. This will treat the rose and prevent ongoing problems from this fungus.
* When planting them, consider spacing out the roses 2-3 feet apart to promote good air circulation. Especially in a humid climate like Houston.
* It is a good idea to dead head the roses on a regular basis to encourage new blooms. once or even twice a month or every two weeks. Just to clip off the spent flowers. You should prune back the rose once a year. Right after the last frost in early Spring.
Again, these roses are a great pick for Houston Landscapes and offer great return on your investment.
