Cheapest way is to buy a “Y” from your local hardware story and run a secondary hose to the garden ($10 tops).
And you can add a battery operated timer to that line if you want ($ 20 and up).
Or you can do it more permanently by splitting the line before the faucet; most folks are not inclined to tackle that, but would be $$$ calling a plumber I am sure (materials under $50).
YMMV

That is a fabulous suggestion! I can run a hose along the house. So simple.... Thanks! GG
