I live in zone 6. The temperature is mid to high 80s. Rain level for the past week is low. I have read your articles on planting and transplanting; however, they didn't say anything about midsummer planting, spring and fall yes. I was given a beautiful rose bush and I need your help. Thank you very much.
Can I Plant a Knockout Rose in Warm Weather
Yes you can plant the rosebush in those conditions. I do recommend using something to shade the rosebush from the sun during the hotter parts of the day. Such as a tipped over lawn chair of umbrella. Keep the rosebush protected like this for 2 to 3 weeks once planted. Water the rosebush with some water that has both a good root stimulator and a product called Super Thrive in the water, use such a mix the next 4 times it needs watering. This helps with any stress from transplant shock. The rose will likely shut down on blooming for a while until the root system gets going well.
