Interview with author and container gardening expert, Barbara Wise.

By , About.com Guide

I met Barbara Wise a few years ago and we became instant friends. She is warm and smart and a true container gardening expert. In her job as the Floriculture Director for Southern Land Company, she designs and plants hundreds of containers and garden beds each season. She also writes and shares photos of her container garden designs on her wonderful and informative website, Bwisegardening: Cultivating a Culture of Gardening. Barbara is also the author of Container Gardening for All Seasons: Enjoy Year-Round Color with 101 Designs.

1. What is your background and how did you get started container gardening?

I actually started container gardening after I first got married to my military husband and lived in areas where I had no other option for gardening except in containers. Most of the military housing at that time did not allow for changing your landscape or gardening so I resorted to planting in pots. I also have always been somewhat of a plant nerd and love to collect plants. Because we lived for so many years in places that I knew we wouldn’t stay for too long, containers were a great way for me to display my plant passions.

2. What is your climate like and what challenges or advantages does it have?

Middle Tennessee has the best and worst of both worlds – zone 6 gives me a wide range of plant options to play with. It gives me the low temperatures that make winter container gardening a thoughtful process of what stays evergreen, what containers can handle the hard freezes or how can I help containers handle these hard freezes. Middle Tennessee can also have long stretches of upper 90’s and drought conditions so I have to think of summer time heat when planting containers. Containers dry out quickly during our summer months so I need to plan for that with irrigation or drought tolerant planting.

3. Do you have a particular design style or philosophy?

I like using color echos – finding a bit of color in one plant to be reflected in another plant used in that container. For example, I like to pair Strobilanthes ‘Persian Shield’ with Torenia ‘Golden Moon’ because the purple throat of the Torenia echos the purple of the Strobilanthes. I also like mixing big foliage with small, fine foliage – a tip I picked up from Rita Randolph of Randolph Greenhouses in Jackson, TN.

4. What advice do you have for beginning container gardeners?

Know your limits. If you know you will be busy traveling/working/taking care of kids, be willing to start with one or two easy care containers. Develop a small habit of container care and build on that.

Don’t always follow the sun requirements written on the tags of plants. Talk to knowledgeable folks – your local extension agents or garden center personnel- to know how certain plants perform in your zone. And know who your plants’ friends are – plants need to be combined with other plants that require similar soil moisture requirements and sun needs.

5. Do you have any favorite plant combos?

For winter containers, I love using Camellia ‘Yuletide’, Lonicera ‘Edmee Gold’, and Heuchera ‘Obsidian’. Summer full sun favorite is Mandevilla, Euphorbia ‘Diamond Frost’, and Setcreasea ‘Purple Heart’.

6. Do you use edibles in your container designs?

I often use Rosemary Arp in my winter containers and have done window boxes and planters filled with herbs. Tomatoes do great in large containers – remember to add a trellis to support them or try the smaller bush varieties of tomatoes. For beginners, I recommend NOT starting from seed with your container combination – use some of the starter plants found in your local garden centers.

7. What do you think makes a container design work?

This sounds so simplistic – a container design works if it meets the needs of the owner: by putting the right kind of plants in the right kind of container in the right kind of sun location for a container owner who can handle the right kind of care. For example, if the goal is to get a lush display for a front southwestern facing entrance container, and those are filled with a large Kimberly queen fern (a sun loving fern), Scaevola ‘New Wonder’, ‘Angelina’ sedum, and ‘Ruby’ Blizzard Ivy Geranium – that would make this design work for that person.

8. Are there any plants you don't think work in containers?

Peonies. But that is because they don’t like to be moved so if you are going to put them in a container for 20+ years, then you can prove me wrong! And really large trees unless you are working on a Bonsai project and I’m not the one to talk to about that.

9. Of the hundreds of containers you've done, do you have a favorite?

‘Hula Girl’ Hibiscus, red ivy geranium, blue violet Tapien verbena. Totally meets my love for bodacious color.

10. Do you have advice on choosing a pot?

I probably have more advice than you have room for ! I have strong opinions on this.
  • Unless you want a water garden, make sure your container has a hole.
  • Look at your home style and make sure you don’t have something like formal iron urns on your log home – match your container style with your home and garden design style.
  • The two biggest mistakes I see folks make - buying a container that holds too little soil for sustaining anything beyond succulent plants and buying containers too small for the areas needed.
  • Think of buying your container like you would a piece of furniture. A quality container will cost more but could last a lifetime. Cheaper planters are great for those who like to change things out a lot, because that will be what you end up doing.

11. Please tell us about your book, Container Gardening for All Seasons.

Being able to work full-time designing container plantings and gardens is a dream come true for me. But what burns in my heart is a passion for seeing others find the joy and benefits of gardening for themselves. This book was born from that passion and the interactions I had with so many folks who had a desire to make beautiful containers but never felt that they were very successful. It starts with the very basics – choosing the container and has step-by-step instructions for planting your container. I also have a plan-a-gram to show exactly where the plants are to be placed in the pots, ideas for container planting for each season, and alternate plant options for different zones. Because I love stories, I’ve woven into all this real-life stories of the plants or container plantings that I’ve encountered over the years just to keep things entertaining.

12. What did you learn from your blogging project, 365 Days of Container Gardening?

I learned that I have enough pictures to do about 10 years of container gardening! And I learned that a daily commitment to write was a huge commitment not only for me but for my family. I took a month off and then started another daily blog only to find that my family was in revolt over my starting another year of every evening sitting down with my computer and writing my post. While I know that there are ways to post-date blogs, I enjoy the daily discipline of writing plus the opportunity to weave daily life/news/events into the post. When my family revolted, I decided to delay my daily devotion of chronicling my container crush. But I’ll be back– just have to get number 4 son into college.

I also was pleasantly surprised by all the people who followed the blog that I never knew about. More than once I had total strangers who would come up to me at talks I was giving, or at church or gardening conventions and say, “I’ve loved following your container blog – you’ve given me so many ideas to use.” That made all those late nights after work, dinner, laundry, visiting with family, then finally writing the post worth all the effort.
