M: Hello and welcome to today’s show, Shirley’s Garden. Today, we’ll be interviewing Shirley on her amazing techniques at growing a garden. Thank you for being here, Shirley.
W: You’re welcome.
M: Shirley, you truly have an amazing garden. Can you tell tm how you learned about gardening?
W: Well, this spring I took a gardening class. Then I decided to try some of the things I had learned. So I have tried various attempts at gardening and with different degrees of success.
M: From the pictures of your garden, I’ve seen ’all kinds of different vegetables, including cucumbers, tomatoes, straw berries, carrots and so on. Could you let us know how you put these plants together in your garden?
W: Well, one of the most important things in gardening is that you choose a good location. You need at least 6 to 8 hours of direct sunshine. Um, you also need to choose a location that has good drainage, and it should be a convenient location. After choosing a good location, I just decided what I wanted to plant, and based on what the final plant would took like, I divided the whole garden into different parts.
M: Shirley, I’ve noticed some vertical beams in your garden. I’m truly amazed by them. Could you explain that to us a little bit?
W: Well, take cucumbers for instance. Cucumbers take a lot of space when you grow them out on the ground, but I don’t have that much space. So I just grow them up. Just grow them vertically. I just used a metal frame and some strings to allow them to grow up, and they will support themselves.
M: Well, Shirley, this is truly amazing. Thank you very much for being with us today.
W: My pleasure.
