I garden while sitting in a shower chair on the lowest height. I do raking, garden cleaning, mulching, trimming, and planting. Even on oxygen and a bad back, I can do all my own gardening. My breathing isn't good if I stand and move a lot. I roll out an E tank, sit, and have a good time

Excellent Mark try to keep it up I admire you for what you’re doing.

I added more tubing to my stationary concentrator. 100 ft max.
It helps around the house. I go out with my portable only if I carry a spare battery and I know it will be a short walk. The treadmill is helping me with stamina. Not fast but 30 to 40 min is about my limit.

Some sort of weave thing that is used to bundle wires in. I use it on my oxygen line so it doesn't get tangled.
Wind my oxygen line up my shirt to keep from getting tangled.
Wear oxygen when you are outside in the garden )I haven't learned this one yet--see what next spring is like)

A shower chair to garden with is a wonderful idea! Keep'em coming!
