Ok here are the basics:
Hand Trowel & Spade $1 each
Gardening Gloves $2
Shears $2.50
Water Hose $7.50 (50')
Good Spray Head $5.50 (i got two :))
Bucket or Bag (i already had this at home)
I would suggest you go and buy the gloves and hand tools at a dollar store and buy the rest somewhere else for a reasonable price...remember it's just a water hose. I stocked up on all my items this weekend at Big Lots and managed to get out of there for under $20. This won't take long so swing by and get OUT after work.
