What an inspiring thread! I can relate. I'm disabled now so no more playing in the dirt for hours like I used to years ago. Three years ago we moved from NJ to rural Ohio and now we have lots of room to grow so I live vicariously through my dil's planting efforts so it's still fun and it brings back lots of memories but it can't compare to actually being on your knees playing in the dirt with all the smells and the feel of the dirt going through your fingers getting under your fingernails.
My son and dil are rebuilding the front porch that my bedroom overlooks in a few weeks from now and it will have flowerbeds in front of it and I will have a little section to fuss with and water while my dil does the hard part. It may sound silly but I am so excited about it! I'm researching to see what plants will do well in late afternoon sun that are easy to tend to.
I'm enjoying collecting houseplants in my bedroom and choosing each one carefully since my windows face west. As soon as I start repotting a new plant it takes me right back to outdoor gardening and it feels awesome so I have to admit I do love each and every one of my potted plants. Seeing them thrive and seeing new growth is very encouraging and I can't help but smile every time I walk into my room.
