Answer : There really is no one right way to study landscape design. Just as with any other field, there are many different approaches that can be effective. Different people will have different preferences, and what works for one person might not work for another.
That said, some general tips on how to study landscape design might include reading books on the subject, taking classes from qualified instructors, studying existing landscapes (both in-person and through photos/videos), and practicing designing landscapes yourself. Whichever approach you take, make sure you are passionate about it and stay motivated—learning landscape design can be challenging at times, but it’s also incredibly rewarding.
