A. Your plants have the symptoms of a fungal disease called botrytis (Botrytis cinerea) This disease prevents the blooms from opening; buds turn brown and decay.

Why are my rose buds turning brown and not opening?
Balling is triggered by cool, damp conditions, often in a partially shady site, where water-saturated outer petals fail to dry out before being scorched by the sun. The mushy plant tissue dries to form a stiff straightjacket around the petals, preventing the flower from opening.
What causes rose blooms to turn brown?
If the soil is too dry, your rose could develop drought stress, resulting in brown rose blooms.

Why are the edges of my rose petals turning brown?
Exposure to extreme weather causes rose petals to turn brown at the edges. Roots of rose plants that fail to receive adequate moisture become stressed, especially during prolonged periods of direct sunlight exposure and insufficient soil moisture, which can cause petal edges to turn brown.

Why are some of my buds dying?
Improper Watering – Improper watering causes a great deal of stress to many plants. Under watering may cause plants to redirect water from enlarging buds to food-producing areas in an act of self-preservation. Over watering often leads to root rot, or other fungal infections that may destroy developing flower buds.
Why is my bud dark green?
Green: Green is the predominant color of most flowering plants, including cannabis, due to the presence of chlorophyll. Often plant tissues will have so much chlorophyll that its green color masks the presence of other pigments.
Should I cut off old rose blooms?
Removing wilted blooms (known as deadheading) from your roses is an easy way to give your garden a tidy appearance. It also encourages your plants to produce new flowers. Removing the old blooms stops the plant from putting energy into developing seeds, and instead encourages it to produce more flowers.
Why are my rose buds dying before they open?
Rose “balling” normally happens when a rosebud forms naturally and begins to open, but once the new swollen bud gets rained on, soaking the outer petals, and then subsequently dries too quickly in the sun’s heat, the petals fuse together. Eventually, the fused ball of petals dies and falls off of the rose bush.

How can you tell if a rose is overwatered?
Rose bushes can also droop from too much water or soil with poor drainage. You can tell if your rose bush is overwatered because the leaves will turn yellow and droop. Waterlogged soil can lead to root rot and cause the plant to die so be careful not to overwater your rose plant.
What time of day should you water roses?
It’s usually best to avoid watering your rose bushes during the heat of the day. Try to get in the habit of watering them first thing in the morning before the sun gets too high. This lets foliage dry off by the time the cooler evening air gets to them.
Do roses grow well in pots?
As long as you have plenty of sun and a container, you can grow beautiful roses on a patio, deck or even an apartment balcony.
