In my garden there are 2 tall trees. On of them is a Pine. I like this tree as it looks like a beach umbrella.
It has variety of flowers, all have different colors: pink, white, yellow, purple .... It's very beautiful.
I like to walk in my garden.
I listen to birds singing, look at butterflys flying and enjoy the vegetation transforming.
Within it, there is a little vegetable garden.
I like to plant some vegetables ; for example: salads, tomatos, zucchinis, potatos and aromatics plants.
In summer, when it's sunny, I like having my breakfast in it and spending many hours to contemplate.
It's so wonderful. (thank you for the correction)

You don't need to say my garden but for the first time then say It .
