So inspired were we by Deborah Schneebeli-Morrell’s new book Organic Crops in Pots: How to Grow Your Own Vegetables, Fruits, and Herbs ($24.95) that we asked her for some starter tips on how to grow produce, herbs and flowers in the meager space available to city dwellers.
What are your tips for growing plants when all you have available is a fire escape, rooftop or a windowsill?
The essentials are good compost kept moist and regularly fed (but not overwatered), light, some sun and, above all, you need to start with healthy, sturdy plants. The enemy to all successful growing, especially at a height, is wind. This will limit the growth of your crops and destabilize the roots... I would not advise trying to grow in a windy position.
What do you suggest growing?
You can grow almost anything. Certain crops will tolerate some shade, such as strawberries, some salad crops (like rocket and lettuce) and some herbs (mint or chervil). All of the woody Mediterranean herbs (rosemary, sage, thyme, etc.) need warmth and sun, while sweet basil needs warmth but will tolerate a little shade. You can grow small bush tomatoes in a sunny window box along with delicious herbs. Even a large pot of blueberries would do well, but don’t forget to protect (using a net) the berries from birds as they ripen.
Any tips for making those plants more vital?
Always buy healthy-looking young plants or buy your seeds from a good supplier; I favor organic where possible. Keep the compost moist, not wet, and don’t let it dry out. I like to water at the end of the day—it’s my quiet meditation time! Use companion planting with your vegetables to ward off any unwelcome pests. Never use chemical pesticides; they leave an untold legacy on the natural world as well as on human health.
What supplies does an urban gardener really need?
In reality, you don’t need much: one or two carefully chosen containers, some bags of good organic compost, a smaller amount of well-rotted manure—you can often get this from city farms—some seaweed extract for feeding the growing plants, a small trowel-and-fork set, a collection of seeds and/or young plants.
I love the idea of recycling containers to be used as pots, found in your book. What makes a great pot for gardening?
Olive-oil cans make excellent containers for growing chiles or pot basil, and I have even grown bell peppers in a reused plastic bicycle basket.
Smaller plants will manage to grow in a small container, but slower-growing larger vegetables need a larger container, which can hold more compost. Succulents and cacti will grow well in little earth and need little water, so they are an option for unusual and small containers. Some people may want to use old boots, handbags, etc. as planters, but I think this is more of a gimmick than a practical growing solution. Still, if you have a sense of humor, you can try anything that will hold compost and water!
In a small space, I think it's more rewarding to grow herbs and peppers and other things that you only need in small quantities. I find it more fulfilling to supply all my hot pepper needs for the season from one pot than to eat an entire windowsill's harvest of salad in one dinner. If you're just getting started, you might try a pepper plant. My cayenne plant got me excited about what my east-facing windowsill could do.
