Roses/Rose flowers wilting before blooming
I bought a rose called Sonia. It was about 2 feet high. Had couple of buds. They bloomed for a day or so and then wilted.
Soon, I had aphids. Which I treated with an infusion of garlic and dish soap.
Another round of aphids, this time I treated with neem oil spray. The plant would have loads of blooms each flower would last a day max and then wilt off.
Finally I had it planted into the ground. The plant sent up a profusion of new growth. But the problem still remains. Each and every bud turns brown within a day.... Without ever blooming. I live in zone 7. The roses are planted facing east. I use Miracle Grow bloom booster once every 15 days. They are planted in a bed next to a lawn, that gets fertilized once a month.
And now the lower leaves have yellow to brown tips. Am I over watering?
It's a disease that some Roses get
Stop using the MG Bloom booster
Start using a balanced organic rosť fertilizer
Apply rock dust for minerals, compost and mulch.
Control over head watering
Allow plant to dry in between watering
Spray with the following
1 cup milk in gallon water will provide calcium
You should get some liquid seaweed and spray that.
Spray several times per week.
Give it a good pruning for new growth.
Stop fertilizing your lawn with a chemical lawn fertilizer and start using a organic lawn fertilizer instead.
High nitrogen is your main problem.
