Hi everyone,
I’m a gardening enthusiast from Virginia. Recently, some of my flowers, especially roses, have been showing signs of stress:
Leaves turning yellow or brown
Spots appearing on leaves
Some flowers wilting or not blooming properly
My current care routine:
Watering: 3 times per week in the morning
Fertilizer: Rose-specific slow-release fertilizer
Sunlight: About 6 hours of direct sunlight daily
Pruning: Occasional, mostly dead or damaged parts removed
Additional info:
Climate: Hot summers, humid conditions, occasional cold snaps
Soil: Mostly loamy with decent drainage
Membership & Records:
I am a member of the National Gardening Club and have a digital membership card. This helps me keep detailed records of my flowers, track issues over time, and access expert advice. I hope being a member also makes it easier for me to get guidance from experienced gardeners here.
My question:
Can anyone suggest why my flowers might be struggling? Any advice on pest control, disease prevention, or soil care would be really helpful!
You might consider posting photos of the problems you’re experiencing. Please try making them as clear and close-up as possible. Yellowing and browning foliage can be caused my multiple problems and seeing the actual damaged foliage and where it is on the plants helps diagnose what’s causing the problem. Photos of how close the bushes are to hardscape…house walls, side walks, drive ways, block walls or fences helps, too, as reflected/radiated heat can easily cook growth and foliage. You might want to make sure none of the fertilizer actually touches any of the canes or the shanks of the plants. Inorganic fertilizers are made from salts of the nutrients. They have to dissolve in water to be the form of the nutrients the roots can absorb. Those salts, if sitting in contact with rose tissue, can burn the cane, more salt absorbing into the cane than the sap can safely absorb. As they absorb in, they draw water out, burning the cane and the growth above where the salts are entering.
Flowers are very soft tissue. Extremes in sun and heat can easily burn the petals. Flower thrips damage the petals by sucking out sap from them, leaving marks and distorted petals. Other pests such as Rose Midge, Chilli Thrips, Japanese Beetles and many others cause damage. Clear photos of the damage help demonstrate what the problems may be and will help get you appropriate suggestions how to proceed. Good luck!
