If you’d like to try growing an unusual fruit crop that’s delicious and nearly trouble free, consider figs. These trees
will grow well unprotected in Zones 8–10, and also in colder areas if you choose hardier cultivars or give plants proper winter protection.
Selecting trees: More than 200 fig cultivars are grown in North America, with a broad range of fruit shapes and colors. It’s important to select a cultivar adapted to your climate, such as ‘Brown Turkey’, ‘Chicago’, or ‘Celeste’ for colder areas. Also look for self-pollinating cultivars, as some figs are pollinated by tiny, specialized flies native to the Mediterranean and won’t set fruit without them. (Reputable U.S. nurseries sell only self-pollinating figs.)
Planting and care: Plant trees as you would any young tree. Figs need a sunny spot that’s protected from winter winds. Mulch trees well with compost, and apply foliar sprays of seaweed extract at least once a month during the growing season.
Container culture: Because figs are tricky to grow in the ground where temperatures drop below 10°F, if you live north of Zone 7 it makes sense to grow your figs in containers. Use a large container (such as the patio planters nurseries sell for patio fruit trees), preferably plastic to control the weight. Use regular organic potting soil and plant figs at the height they grew at the nursery, top-dressing the container with compost if you have it. Water when the soil is dry an inch below the surface; if you let containers dry out completely, the figs may lose their leaves. (Leaves will regrow, but it stresses the plant and lessens fruit production.) Set pots in a sunny part of the patio, deck, or yard. You can use foliar sprays or water with liquid seaweed (kelp) or compost or manure tea monthly to give plants a boost.
Pruning and propagation: Use a shovel to disconnect suckers that sprout from the roots throughout the growing season; replant or share them with friends. Figs don’t require formal training; just thin or head back as needed to control size. You can propagate figs by taking cuttings, but the easiest way is to bend a low-growing branch down and secure it to the ground or the soil in a container with a U-shaped wire; cover lightly with soil (and a rock if it resists staying buried) and check for rooting. Once the stem has rooted, sever it from the mother plant with pruning shears and it’s good to go.
If temperatures drop to 10°F or colder in your area, and you’re growing cold-hardy figs
outdoors in the ground, you can protect them with a cylindrical cage of hardware cloth filled with straw for insulation (don’t cover it with plastic, which can overheat).
Or you can trench the figs each fall and unearth them every spring. To trench plants, prune them back to about 6 feet in late fall and head back any spreading branches. Tie branches with rope or twine to make a tight cylinder. Dig a 2-foot-deep trench as long as the tree is tall, starting at the root ball of the tree. Place boards on the bottom and sides of the trench. Dig out soil from the roots opposite the trench until the tree is free enough for you to tip it into the trench. Wrap the tree in heavy plastic, bend it into the trench (this will take some effort), and fill around it with straw or dried leaves. Put a board over the tree and shovel 238soil over the board. Resurrect trees in spring after danger of hard frost is past.
Never try to grow figs in the ground north of Zone 6 (even there, plant the very most cold-tolerant cultivars). Instead, grow your figs in containers and bring them indoors for winter. Keep them in an unheated garage, shed, or other protected area where temperatures don’t dip below 20 degrees. The figs will drop their leaves and go dormant, but you should still water them when the soil dries. Figs will stay green all winter in a greenhouse
, and may even bear fruit in the warm, sunny greenhouse climate. Make sure you water them regularly, and watch the undersides of leaves for greenhouse pests like aphids. In either case, bring plants back outdoors when the weather warms and the last frost date is past.
