Alright I'm going to need all of your suggestions as this is the project I'm working on right now.

A bought a small townhouse in Ontario 7 months ago and I have a tiny yard.

The yard had mostly grass, but had a little bit of moss, crab grass, and clover. There is a small garden, and many dirt patches in the yard.

I have spread clover seed in the yard, especially in the dirt patches.

Then I weeded the garden area, removed about half the rocks but left some in the garden, I have my mother coming over next month to help me pick local garden flowers, and I had to pull a tiny tree out because it was planted right beside the foundation of the building and would eventually cause damage.

What else should be added to the lawn? Should I be pulling out the crabgrass? What wildflowers are native to Ontario?
