Gardening Questions

What do you like most about gardening?
I like being outdoors with plants. I am just as happy pulling weeds as planting something new and exciting.

What do you dislike most about gardening?
I hate hauling away the trash. I shred everything I can but the rest must go in the trash --- I hate that! Second I dislike clipped hedges. I prefer correctly pruned or laced plants.

What individual has influenced your gardening interest the most? How?
While taking gardening classes one teacher had a great influence on me,Phil Chandler. He was like the father of horticulture to several of us. He taught continuing Ed Classes in the local area, he offered week-end walks, and taught at the Los Angeles Arboretum. Another great mentor was Jack Catlin, a garden designer in the LA area. He was a member of many plant groups and got me into Bamboo, Bonsai, landscaping, and much more. He was considered the #1 Bamboo expert during his time. He was also into Chinese and Japanese garden design.

What is your favorite place or activity in the garden?
Sitting on the bench and looking down over my Vista garden.

What is your favorite time in the garden?

What is your favorite public or private garden in the world? Why?
Quail Botanical Gardens because I have been so personally involved with the garden and the people there. Also, QBG has the best Bamboo collection in the country. My second favorite is the Huntington-- again I am very personally connected. I know the garden intimately. The succulents in the spring, the palm collection is outstanding and the jungle garden is great. And my 3rd favorite would be the Santa Ana Botanical Gardens because it is a California Native Garden with great design and outstanding plant collections.

What is your favorite color in the garden?
Any color as long as it used in great combinations or any color that gives me pleasure at the time.

If you could grow only one plant, what would it be?

What plant have you tried to grow that has given you the most trouble? Or, what plant would you like to grow and can't, and why?
Bonsai junipers and pines. I just never figured it out so I gave up!

What is your favorite gardening outfit or costume?
Felcos on my belt, a hat because I am bald, pads for my creaky knees. Any old thing I can find like a faded t-shirt and holey pants. I don't dress up to garden. One most favorite is my Hortisexual t-shirt.

Do you have a gardening philosophy you would like to share with other gardeners? What is it?
If it is a huge garden, small garden or little patch -- do it right!

Who is your own favorite gardening personality on TV, radio or in print? Why?
Tom Piergrossi.

What is the one question about gardening you would really like people to ask you?
How often do I water it?

And what's the answer?
The answer is one that no one wants to hear, "When it needs it." Look up the water requirements for plants you are not familiar with their requirements. Sometimes you need to actually check the soil around the roots to see when it needs water.

What is a garden myth you hear frequently which you know is untrue?

And, what is the reality?

What group or kind of person do you think would benefit most from the advice you can give on gardening?
Beginners -- people who are interested in horticulture but are not sure were to start or what direction to go.

Would you like to participate, or can you recommend someone who you think should? We're always looking for more expert gardeners to tell about their philosophies and give their plant recommendations contact us and we'll get started (it's easy and a great way to promote yourself).
