Hi K, lots of good ideas and advice in this thread (and many other threads!). Just start. If you have seeds. Plant them in the ground the best you can. It's ok to change your mind. Observing, changing and feedbacking are very permie too.
You can draw up or sketch an overall design goal for your property. Then pick elements to add as the funds and time are available. OR just toss some seeds in the ground and get water to them.
What ever you chose to do, will be the right thing to do. because you will be learning and growing. Start small and close to your house to enjoy the full benefits.
Happy growing.
