My foray into the world of growing cold hardy fig trees in a northern
climate...... will be growing the trees in big pots. I've
started a small backyard fruit orchard, and my favorite fruit to
experiment with next is the fig. In pots. The fig has great historical
significance, but i'm just interested in the fruit. And lots of
it.
Fig trees, when compared to other
fruit trees, have one of the shortest wait times before you should
expect to bite into that fruit: usually only 1-2 years after planting.
Less, for dwarf tree varieties. Some varieties produce figs twice a
year, sometimes on bare stems.

their beloved fig trees, the symbolism, and the customs that surround
it's care.
I've put together this page of
information on growing the fig trees, dwarf or dwarfed by me, that i
will be following myself.... this is my first experience with attempting
to grow and eat my own figs. All will be grown in pots. I will be
learning, too, and practicing what i type. I'm sure my mistakes will be
valuable to you in your fig growing endeavors.
I'll begin by saying that i live in
the northern U.S., and will therefore be growing cold hardy types for
Zone 6. Mostly.
There will be another experiment going on at the same time with figs
hardy to Zone 7, with proper, but easy steps, to allow it to survive
winter in my lower zone. I hear rumors about several varieties of fig
that grow here, where it's supposedly to be too cold to do so. I have a
fairly decent-sized front and backyard, but i have gotten into growing
lots of things, especially dwarf trees, in pots.
My reasons for pots are that i
garden so intensely, that i'm running out of horizontal space to plant
something that will need root space to grow unhindered. And I am a
compulsive re-decorator of my theme gardens. I appreciate the
portability that encourages my fickle decisions about where to grow a
plant. I also like the idea of being able to grow and care for non-hardy
varieties by just lugging, (or wheeling) the potted plants into my house
to sleep for the winter. During my self-imposed distancing during
Covid-19, i have learned not to care or keep secret that my dining room
looks like an indoor plant nursery, with 20+ grow lights of all types -
clip on, hanging, and telescoping floor-standing lights with arms like
an octopus - placed over that many plants, and a nice window to
supplement that. I'm learning a trick or two about timing, pruning,
dormancy and such. And i don't have to shove things out of the way when
I have guests, because there usually aren't any. I begin to question
whether i prefer humans or plants in my dining room.
All varieties of baby perennials,
non-hardy succulents and trees I over-wintered performed very well with
that setup. Sleeping trees do not need light or much water until
breaking dormancy. Trees budding out or with leaves left on, do. Severe
pruning is best done in winter when the plant is dormant.
I am concentrating on dwarf or
semi-dwarf trees that I can keep at a particular height, so that i can
prune and pick without standing on a scary ladder. That would be any
ladder with more than 2 steps. I choose self-pollinating varieties that
don't need a partner to grow fruit. They will be placed near my
pollinator-attracting plants, so they will have an even bigger and
better crop. Self-pollinating trees, to me, sounds like I can have twice
as many varieties. I limit myself to growing in planters no bigger than
5 gallons - to keep them small and light enough to carry the winter-shy
varieties indoors. I road-tested the future chore of moving trees and
soil and pot, and i determined that 5 gallon pots are the most I can
handle by myself, including the climbing of steps. You can find your
maximum weight requirements, so you might be able to use a 7 gallon pot.
Figs really don't have a preference. They grow into their pot sizes, and
then you can repot and upsize, or trim the roots and repot into the same
size container. The only thing they do not go for is soil that is not
well-draining. Sitting water is deadly for a fig tree. It's easy to
prune and care for dwarf variety trees, but you can dwarf the size of
any fig tree with proper pruning to keep it dainty and at the height you
want it to be. You can even let the fig tree be a bush in a pot. Espalier
fruit tree gardening is fun to try. You can prune and grow
several trees in a sheltered location this way.
2021 Update - My very
first Brown Turkey Fig grown from a rooted tree cutting, and planted in a
big pot this spring, was quite deelish.
I named the tree "Tom". I picked him early, but i'll wait for
his friends to ripen more fully. There's a small window for picking,
presumably just when the neck of the fig feels soft. The fig wasn't brown
yesterday. The new potted fig trees reveled in this summer's heatwave with
lots of water. The real test will be whether they are winter hardy in Zone
6, or whether their first winter dormancy should be spent indoors. I
haven't decided which to try, yet.
To begin, here are the suggested
varieties of fig tree to grow in my area (Zone 6b), that are described
as cold hardy, or at least borderline, according to my research. Many
varieties of fig are hardy to Zone 7, are described as also being
prolific in Zones 5 and 6 if grown in a sheltered area, or steps are
taken to insulate the tree.
Remembering that potted trees freeze
faster than trees planted in the ground, is a good idea. You can look up
fig trees that are hardy to your area in nursery listings for the tree,
but I would double-check with fig tree collectors, growers and nurseries
to be sure. They specialize, so I trust that more. If you're growing in
pots and have a cold basement, garage or shed, you can bring the pots
inside to sleep through the winter after the leaves drop, so cold
hardiness won't matter, you don't have to wrap the trees like mummies,
and you can choose almost any fig tree.
Do yourself a big favor, and
purchase your trees from reputable plant nurseries and fig breeders. I
don't trust anything from big box stores, home centrs and flea markets
to be grown pesticide and GMO-free, or be true to the species named on
the tag.
Container Planting
Get a nice, big, pot - make it plastic unless you
don't plan on ever moving it around in your garden. I love the terra
cotta and stone pots, but i ain't moving those - I suggest 5-7
gallon pots. Figs don't need all that much room in a pot. Plant in
well-draining soil and skip the fertilizer at planting time.
After planting your fig tree
in its container, water it well, then add a layer of mulch. The
mulch will keep the soil from drying out too quickly, and you can laugh
at weeds. Put the fig tree in a sunny spot in your yard, and keep well-watered. During
hot summer weather, your fig tree may need more frequent watering,
possibly even daily. Observe and respond accordingly to your tree's
environment. If your tree's leaves begin to yellow, chances are it
is being over-watered.
Pruning your fig tree. Unlike
most other fruit trees, fig trees typically don't require routine
pruning, but you can prune them to a size that works for your space.
Depending on the variety, average fig trees naturally mature around 10-
to 15-feet tall or larger. Many fig-tree growers find that keeping them
between 6-8 feet tall is most manageable, especially in a container.
Some fig trees have a natural bush-like appearance if allowed to grow
naturally. If your fig tree has more of a "bushy" shape and
you'd prefer one main trunk, you can prune the additional low growth out
until you are left with one main trunk. I do this regularly with all of
my potted trees and shrubs.
In the fall, when the leaves start
to turn and fall before the first killing frost, it is time to move
the not-so-hardy fig trees you've planted into an unheated basement,
garage, or shed where the fig tree will go dormant. Check occasionally
during the dormant period for soil moisture.
Be sure to allow the soil to become dry to the touch 2-3 inches below
the soil surface before watering. Dormant roots don't take in much
water, but the moist soil keeps the roots from drying out. Avoid
drenching or overwatering your dormant fig trees to avoid root rot
during its long sleep.
As warmer weather arrives, move the
fig tree (this should be easy because you made sure you planted it
in a pot you can lift, right?) out to the yard for just a few
hours every day. This will help acclimate it back to its
favored warm weather. Take it back indoors in the evenings. When the
last frost date has passed for your area, move the fig tree back to a
sunny spot outdoors. There is some info online about planting bare root,
dormant trees as soon as the soil can be worked, and before the last
frost date - that's for those of us who purchase bare root plants and
need to pot them or plant them when they arrive.
In summer, water weekly or more
often, in heat/dry spells.
Of course, the best place to plant
fig trees in the ground, is close to a south-facing wall or structure.
It's warmer and sheltered there in winter. Potted fig trees can do well there,
too, if given a lot of mulch, moved close together, or their pots are
insulated. I've heard tales of zone 6b gardeners growing all types of
cold hardy fig trees, and they never mulched. I'm not feeling that
lucky. Especially with young, finicky and fairly expensive trees.
The listing below are my beginning
choices, based on research on figs that are cold-hardiest. Most growers
agree that you can grow figs in-ground in zone 6b with minimal
protection. The descriptions were provided by nurseries and
growers.
These are the varieties I will start with, and I'll expand into the
warmer-zone varieties as i gain experience. We shall see.... |
