6. Buy some bloomers
"Conventional wisdom dictates you shouldn't buy perennials that are actively blooming, and if you do, you should nip off the flowers during planting. But there are two exceptions: irises and peonies. Plant tags get switched around and unless the plant is in bloom, you can't be sure what you're getting."
7. Keep your receipts
Keep your receipts "A lot of nurseries offer one-year warranties for their plants. keep all of your receipts so you ca n return purchases if they develop issues and don't survive. But be fair to the nursery: if you don't care for your plants properly, don't expect them to pay for your mistakes."

8. Take cover
"Bring a tarp or sheet to line the trunk of your car. I'm often cleaning spilled potting soil out of the nooks and crannies of my trunk."

9. Find an expert
"Are the employees at your garden store experts or do they cover all departments? Make sure you talk to someone with a solid background in their area of expertise to ensure you're getting the best advice."
10. Play with your plants
"Use your shopping cart as a moveable blank stage to mix and match plants and create dramatic combinations."
