Ants on rose bushes. Ants are attracted to rose bushes because of another pest that has already taken up residence in the garden, the aphid. Ants love to feed on the sticky, honeydew residue left on the plants by aphids. Then they carry the aphid Read more
Theoretically, you can't overwater a rose. Of course, if you have no sun and steady rains for ten days, your roses won't be thrilled. But if drainage is good, the extra water usually won't hurt them, either. Start with a watering schedule: Water once every Read more
Soil, temperature, and surrounding plants affect how much water a rose needs. If it comes out muddy, there might be too much water or not enough drainage. Another indicator of too much watering is yellowing leaves that are soft. Yellowing leaves that are dry and Read more
Two inches of water a week (4 to 5 gallons) may be all that is needed. If the soil is sandy or the garden is hot, dry, or windy, more frequent watering may be necessary. Care needs to be taken in areas where the soil Read more

Rose bushes are notoriously delicate plants, prone to both disease and infestation by damaging insects and fungi. Rose growers typically treat the bushes with large and frequent doses of pesticides, then chemically treat the cut flowers before transport. Pesticide use also concerns human rights activists.
Excluding Ants Ants don't directly harm roses, but they may encourage sap-feeding pests by protecting them from their natural enemies. Ants harvest the honeydew that these sap-feeding pests produce in abundance. When ants appear on roses, check the plant thoroughly for sap-feeding pests before excluding Read more
Shrub roses should always be pruned by cutting stems back to a healthy bud. After you cut, look for healthy white wood in the cut. If it is brown, continue to cut until you reach white wood. Make your cuts at a 45-degree angle, about Read more
Rose powdery mildew is a fungus that produces airborne spores from infected stems or buds on roses. After overwintering on your plants, the disease is most likely to flare up if the roots are in dry soil and the leaves are in humid air – Read more
All roses are perennials in their species- and cultivar-specific hardiness zones if they are planted properly and receive the right care. There are shrub roses, which tend to be wild, old garden roses or species developed before 1867, and modern roses, which include most hybrid Read more

Landscape or shrub roses may really not need any additional fertilizer. These plants are more vigorous than the old hybrid tea types. As a result, they will normally flower all summer long on naturally occurring nutrients in the soil.
Roses (genus Rosa) are naturally pollinated by insects such as butterflies and bees, by hummingbirds, or through wind transfer. However, hand pollination, also referred to as manual or mechanical pollination, becomes necessary when conditions prove inadequate for natural pollination.
The main reason roses don't bloom is they aren't getting enough direct sunlight. You say your plants are in full sun, but keep in mind they need at least 8 hours of direct sun a day. If there's a tree or building nearby, they might Read more
