Q.What to do after oriental poppy plants die off?
What do I do after my oriental poppy and long stemmed poppy plants die off? I’m very new to planting flowers so I reached out to a landscaper to plant flowers and shrubs in the front of my home. The work was done before I got home from work. The landscaper didn’t give me any instructions on how to care for my new plants and shrubs. The landscaping looked beautiful at first but the oriental poppy died off quickly and the foliage is brown and withered. I removed the pod after reading tons of stuff on the Internet. I’m not sure if I did the right thing by snipping off the pod. The long stemmed poppies are flopping over and I don’t know what I should do with them? I would be so grateful if you can give me some advice!
I read too much stuff on the internet on how to care for poppies, but I found it all to be confusing.

Make sure your providing your new plantings plenty of water. When temperatures rise in the summer, watering may need to done even twice a day.
