How about some gear that boost fishing luck and both fishing and gardening leveling? This would be gear with energy, and either gardening or fishing stats and spells.
As far as "wands" go for these, a fishing rod would be awesome for a fishing wand. Fishing net, standard rod, fly rod, or deep sea rod are what I was thinking here. You could also have a fishing boat or other craft as a mount that assists with fishing.
Wands for gardening could be spade, shovel, rake, or other gardening tools. A mount could be a mule drawn tiller.
Could be fun to really dress the part for what you are doing in game.
