How do you say

I am learning to drive, and I hope to be able to drive on my own in three months.

..in Chinese?

我在学习開車,希望三個月後可以獨立上路。

wǒ zài xué xí kāi chē , xī wàng sān gè yuè hòu kě yǐ dú lì shàng lù 。

How do you say "I have taken up gardening, and spend a lot of time every week on my little plot." in Chinese?
