My rose tree (long trunk with hundreds of mini pink buds and a few pink roses). Started out with a reddish pink bloom and is now only producing a pale pink bloom and very weak blooms that either blow away with a big wind or if you touch them they fall off. There are no holes in the plant from bugs on the top of the plant. It is sharing the same spot with 3 other rose plants, some small morning glories, and begonias. They were planted in rose soil.They are watered once a day, sometimes twice due to dry conditions....if they aren't watered they look like they are going to die. Help!!! this is my first time with roses and I don't want to kill them....Blessings for a wonderful summer season. Tammy Sumner

First, watering twice a day seems excessive in your climate, even in dry weather. It is best to water deeply and thoroughly less frequently, rather than to sprinkle lightly and frequently. When you water be sure that water is soaking about 2 feet deep, through the entire root zone to the edge of the plant's canopy. To gauge how far water is soaking, use a soil probe (any long, pointed piece of metal or stick). It will move easily through moist soil but stop at dry, hard soil. It may be necessary to let a hose run at a slow trickle for a time to soak deep enough.

Bud blast is the drying up and failure of flower buds to open. It's a physiological condition with many possible causes, such as root injury, cold soil, high temperatures during cloudy weather, dry conditions during formation, a lack of potassium in the soil, or excessive shading. Do you think any of these conditions are present? I hope this info is helpful.
