Just a couple of weeks ago, the little store down the road was charging $12.95 for 50 pounds of potatoes. This week, they are selling for $4 a bag more. That’s quite the price increase!
As you look at your grocery bill, you are probably thinking about supplementing your groceries with home-grown goodness. Besides, what you grow has so much more flavor than what you will find in most any store!
Whether you have a postage stamp size spot of dirt or room for a large garden, make the most of what you have.
Terracing your plants involves arranging them in steps so that each one gets plenty of light. Many city gardeners have an overhanging roof or a nearby building that blocks the midday sun, although their gardens get a few hours of early or late light. If your best sunlight hours are in the early morning and/or late afternoon, then your sunlight will come mainly from the side. An outer row of plants will get most of this light energy while any inner rows may be completely blocked by these outer plants. By terracing your plants instead, putting the tallest ones in the back and the shorter ones in the front, you can grow a lot more under these conditions.
You can terrace plants in one of two ways. The first way is to arrange your garden so that shorter plants such as greens and carrots are on outer rings or rows (facing your late or early sidelight). Taller plants such as tomatoes, peppers, and legumes should be placed further back in this scheme. If you have enough space for more than two parallel rows, then you can either use multiple rows of shorter plants, or else terrace in three heights. If you terrace in three heights, be sure to trim or train the middle row of plants anytime they threaten to block out the back row. The second way to terrace plants is to design the garden itself at layered heights. Using raised beds, containers of different height, or cinderblock boosters, you can lay out the garden so that even plants of similar heights will each get that early or late sun.
Trellising is another great vertical gardening technique. Several varieties of vegetables grow particularly well when trellised. Plants with natural vining tendencies include cucumbers, peas, and beans. These plants have limited root systems and a natural inclination to climb skyward, so they can be planted relatively close together and will make very productive use of available planting space. Tomatoes, squash, and small melons also can be trellised and trained upward.
The cucumber is a great example of a plant you can train vertically. From the moment a cucumber has its first few leaves, it begins to unfurl its tentacles, grabbing hold of the nearest support. It may fix itself to a wire rod, fishing line, bamboo pole, wooden fence, metal railing, or neighboring plant’s stem. Using this support, the plant climbs upward and outward, building its vine. In a city garden, you can use any available material to make a trellis for each plant; just keep it less than half an inch in thickness so that the plant can grab hold. A length of fishing line or twine that is tightly wrapped back and forth from a railing or nearby pole is as good as anything else for training cucumbers and peas. Effective trellising enables you to keep plants off the ground and allows you to raise one plant from every few inches of soil. One additional trick to maximize space with cucumbers is to alternate the trellis back and forth for every other plant, so that they grow upward in a V shape. Plants 1, 3, and 5 are encouraged to climb forward and upward, while plants 2, 4, and 6 are trained backward and upward. Peas and beans can be planted quite closely together, and peas especially are accustomed to being crowded; they will produce well as long as they have enough air circulation to stave off diseases such as mildew.
Tumbling involves growing plants downward from a hanging planter. If you have more airspace than floor space, consider hanging a planter or two from your ceiling, eaves, window ledge, or railing. Strawberries, cherry tomatoes, herbs, and bush beans grow extremely well over the edges of hanging planters, providing you with fresh food that “tumbles” down into your vertical growing space. Although most hanging baskets are designed more for flowers than larger rooting vegetables, you can hang any type of container that can be supported (just remember, wet soil gets quite heavy). Clay pots, buckets, and window boxes all can hang vertically. If you are using a container such as clay that has no holes for hanging, you may want to invest in a hanging basket, or else you can use a few pieces of wire, rope, or twine to create your own supportive cradle for the pot.
Hanging planters of any sort can be a great place for growing cherry tomatoes, strawberries, bush beans, herbs, or even smaller cucumbers. Vinelike veggies that tumble over the side are especially effective at using vertical space. The key is not to plant anything too big, because hanging planters usually are limited in size. Recommended varieties with a trailing habit include “Cool Breeze” cucumbers, “Patio Temptation” strawberries, “Tumbling Tom” or “Tiny Tim” tomatoes, and any variety of bush bean or edible thyme. There are more varieties developed each year for specific purposes such as this, so do not confine yourself to these suggestions. If any fruit gets heavy enough that it threatens to break off, tie it up with some twine or a piece of cloth. In smaller hanging planters, consider growing some edible flowers, herbs, baby salad greens, or wheatgrass for juicing.
