>> right now I am watering every day..ugh!
I was surprised that the start-up costs for basic drip or spray irrigation aren't too bad. Little sprayers are very cheap, and 100 feet of mainline tubing can be found for $14 (1/2 inch) or $20 (3/4 inch). Dripline or drip tape eliminates evaporation, and are probably the best way to go for very large beds with regular shapes.
Electronic timers and filters can get expensive, or you can go cheap on the filters and replace the sprayers as needed.
To use the inexpensive fittings, you may have to regulate your water pressure down to 20-30 PSI. My city water pressure was 45 PSI, and certain threaded fittings couldn't "grip" some kinds of tubing at that pressure. Those can also get expensive but don't need to: $8 for

I found a wind-up timer that I have to set manually each time I wnat to water, but it shuts off automatically so I can walk away: 10, 15, 30 minutes, or anything up to 120 minutes, and there are no batteries to go dead. (Gilmore 9301 Single-Dial Windup Timer, $15,

Plastic fittings to adapt from that black polyethylene mainline to hose threads are only a few bucks each, so you can also put a valved spigot next to every bed for $5 each, if you want. That makes spot-hand-watering really easy.
