How to Grow Bright-Colored Yellow Roses
Yellow roses descended from three rose species: Rosa ecae, Rosa foetida and Rosa hemisphaerica. In the beginning stages of hybridization, yellow roses were susceptible to disease and difficult to cultivate. After considerable cross-breeding with sturdier rose varieties, yellow roses are now much easier to grow. Many species of yellow roses boast colors ranging from true yellow to copper-yellow. Single- and double-bloom varieties are available. Does this Spark an idea?

1
Plant the yellow rosebush in an area that receives full sun during the day and shade in the evening.
-
2
Spread 1 to 2 inches of mulch mixed with compost around the base of the rosebush in early spring and again in the summer. Don't allow the mulch to touch the base of the plant.

3
Water the bush in the early morning or late in the evening every day. The water should not puddle on the surface of the ground. If roses wilt in the heat, water a second time during the day.
-
4
Pull blooms from the bush during the first year to encourage root development. Instead of using energy and resources to produce blooms, the bush will develop a strong root system. After the first year, pull dead blooms from the bush, a process called deadheading, to encourage new growth.
-
5
Spread or spray fertilizer containing magnesium sulfate to deepen the color of the blooms. Alternatively, you can sprinkle pure magnesium sulfate, or Epsom salts, around the rose in the spring and use general-purpose fertilizer during the blooming season. Spray liquid fertilizer on the rose and into the soil surrounding the bush every month, or spread slow-release granules on the soil around the rosebush in the spring and fall.
