Gardening and Horticulture - Rose blooms

I have 3 large rose bushes. Two of the bushes produce lots of blooms. However they get very droopy and limp. After a day or 2 the blooms are no longer facing up , but have fallen over and are facing down.

What could be causing this.

Are you watering deeply? It's best to water deeply once a week than to apply light waterings every day. The idea is to develop strong roots that go deep in search of moisture. If you stick your finger into soil and soil is not moist, it's time to water. As you mention no other symptoms, problem may be a result of moisture issues.

My sprinklers probably are not getting deep enough. The ground is mulched so the top soil is damp. I will try to water deeply about once a week.

Make sure mulch is not more than 2-3". Keep it fluffed up so water can get through. Do not allow mulch to touch the stems. Replace mulch each spring to minimize opportunities for disease.

Do not allow sprinklers to hit the roses. Water roses from underneath. Water deep at least once a week if there is no rain. Stick you finger in the soil to test for moistness. Roses need lots of water. If they do not get enough they can wilt, drop leaves, grow smaller, leaves or become dormant and quit blooming. Too much water can result in yellowing of leaves at bottom of plant and leaf drop. Soaker hoses do a good job of deep watering. Or, you can fill a 5 gallon bucket that has a hole or two in the bottom and place beside the rose. 5 gallons of water slowly soaking into soil should provide the rose an 1" of water which is needed each week.

You can taper off watering as cold weather approaches, but soil should never be allowed to completely dry out even in winter. Keep track of rain fall and check soil for moistness. Stop fertilizer about 6 weeks before fall frost. Depending on how cold it gets where you live, you might want to pile on more mulch for winter protection. This can be leaves and straw. You will want only 2-3" of fresh mulch in the spring.

The rose is for the most part very healthy and has tons of blooms, they are just droopy when they open up. When the bloom is developing it grows upright but as the bloom opens and gains weight it sags down.

With deep watering and proper fertilization, you should have strong roots and stems that should support the rose blossoms. Water deep. Use your finger to test the soil for moisture. Invest in a soaker hose and always water roses from underneath.
