You can fast forward by a few hours but you have remain in the same calendar day. After your house is built your secretary gives you a housewarming gift. As long as you refrain from upgrading for awhile and don't put any other items or furniture in your house you can put what she gives you in your inventory, go outside, go back in and another one will be there.

There are only 6 kinds. You need multiple patches of crops and a few of each fruit tree

Plant them next to each other in the garden.

That only works until you place something else in your house or upgrade it

Plant them all next to each other in the garden. They crossbreed that way
