Garden supplies / comfortable garden attire

My grandmother is over 80 years old still gardening after over 30 years in her garden in which she feeds our family and donates to the homeless from. I want to hook her up with new athletic apparel (comfortable clothes and shoes) and brand new gardening supplies. 

We could honestly never never repay her for all she does but I want to do something nice and show her how inspiring she is not just to us but the community at large.
