To have a garden IN your house means literally inside your house there is a garden - meaning the ground is grass, stones, etc. For plants that are inside the house, we'd say something like, "I have a lot of houseplants" I now have a house with a garden = you have (at some point) moved into a house which (already) has a garden Now my house has a garden = you lived in this house, and later, you created a garden to add to it

Although Imy house now haves a garden in my house now,it, the grasses in there are totally artificial grasses in my garden, since I have no time to maintain thait. Although my house now has a garden in it, the grasses in there are all artificial, since I have no time to maintain it.

How do you have a garden inside your house? Maybe you mean "at your house?"

1. Since this is a hypothetical, you need to use the conditional tense 2. “A tomato” sounds weird, as tomatoes normally grow in bunches
