Potted plants are always a nice way to add some color and texture to a space. Consider some seating with accent pillows and a hose box to disguise your water hose. String lights would be a fun addition for night time enjoyment of your space as well. Good luck with your project!

I was just about to suggest some of the same things that Russell Landscape suggested, especially potted plants!

Thank you for the comments, especially the potted plants idea. I do have patio seating underneath the lemon tree, but have to keep it covered because it often rains. This problem would not be solved by an umbrella. Is there any way to keep the furniture protected and looking nice at the same time?

Better late than never, I guess. Here's how the patio is coming along. Thanks, and please, keep it coming. I take a while but I do follow Houzzers' advice.
