also - keep garden tools clean and sharp ....nothing will work you to death faster than a dirty, dull shovel or hoe
another handy garden tool is a pitch fork ....
Hose -
assuming you are in the USA ... water faucets on the exterior of apartments, houses & homes are "garden hose thread" ... "garden hose thread" will accommodate garden related hose, nozzles and sprinklers
garden hose are made from a variety of materials .... the "most expensive" is not always the best ....and "high tech" isnt always suitable for "outdoors"
you will want a garden hose (or a few hoses) that will reach every part of your property ....
in the USA ...the 3 main sizes of garden hose is 1/2", 5/8" and 3/4" ..... with 5/8" inch being the most common & most useful ..
In my opinion, unless you have a pool to fill and the water pressure to do it ...stay away from 3/4" ....
I would recommend a 5/8" Heavy-Duty "kink free" garden hose with *brass fittings* ... (combinations of metals when screwed together tend to seize-up over time ...such as: zinc / aluminum to brass)
while you are buying a garden hose ...pick up a spray nozzle and sprinkler ...the nozzle for "manual watering" / sprinkler for "auto watering"
before turning on the hose ...let natural rainfall supply most of your watering needs
