How to Grow Fig Indoors

Figs are one the best fruits to eat FRESH (they start to degrade immediately after picking them).

 

 

Best Fig varieties to grow inside.

Ficus varieties can grow well both indoors and outdoors. We’ve picked some of our favorite indoor fig varieties for you:

 

Best Setup for Fig Plants

You’ll need:

Planter: 

A pot that is at least 12″ / 5 gal, though there is some flexibility. The plant will grow in proportion to its planter – so size is based on how tall you want your plant to grow.

Soil: 

Standard Potting Mix

Plant Food:

Balanced Blend. This should be equal parts nitrogen, phosphorus, and potassium (with NPK numbers like 10-10-10). 

Grow Light:

A strong grow light that can give the equivalent of 6+ hours of direct sun [DLI of 18+ mol/m²/day].

Starting your Fig: Seed vs Propagate

Fig that’s grown to eat is usually started with a live plant or cutting. This is because plants grown from seeds will grow as “wild types” – meaning they won’t produce the same fruit they came from (think of crab apples!).

Why you shouldn’t start Fig from seed

If you grow a Fig from seed, it won’t grow “true to type” meaning the fruit you will get will be a weird cross between the many different varieties – and chances are it won’t taste very good. This is why Coffee seeds arent really available

Propagating Fig: How to Clone from a Stem Cutting

If you’ve already got a Fig plant you love (or a friend does!) you can easily “clone” it with just sharp scissors and a clean glass of water. First, cut a couple 6” shoots of new growth (avoid anything woody). Next, remove the lower leaves, so the bottom half is just stem. Place in a glass of 3” of water, making sure the cut leaf spots are underwater. Place the glass on a bright windowsill and change the water every few days. In a couple of weeks, roots should emerge and you can transplant them into your container. While using additional rooting hormones won’t hurt, it’s not necessary with Fig plants. 

1. Cut 6” section of new growth
2. Remove leaves halfway and place them in the water on a sunny window sill 
3. Wait 21 days for a few ½ inch roots to form and carefully transplant into their final container

How to Transplant Fig

Many nurseries ship Fig as “Bare-Root” – this means the roots are not in soil and the plant is dormant. It’s a bit strange to receive something that looks like a bare stick, but it’s much easier to make sure you’re not bringing any pests in. To transplant your bare root Fig plant:

1. Prepare your pot by filling it ½ with soil and shaping it like a cone
2. Prepare the plant roots by trim any that seem dead, mushy, or excessively long, then shape it like a cone to fit on your soil.
3. Check the fit so that the highest roots are just below the rim of the pot. Adjust the soil as needed. 
4. Once the fit is good, fill the pot up to the highest roots, lightly tapping the soil down as you go. Finish up by giving it a good deep watering.

If you received your plant in a nursery container with soil, the process is much the same. Once it arrives, gently pull it out to check on the roots (adding water can help if it’s dry).  If they’re not hitting the edge and there’s plenty of soil, then resist the urge to transplant it into a bigger pot. If the roots are crowded and starting to circle around the pot, then you’ll need to repot it. Use a slightly larger pot (2 to 3 inches larger in diameter). Fill the bottom with enough new soil so that the top of the nursery pot lines up with the top of the permanent container. Finish by filling around the edges and watering thoroughly. 

Where to grow your Fig plants

While you should take advantage of the sun (it’s free and perfect for plants) there are limited circumstances where indoor natural light is enough for Fig plants to grow well. A very bright window can cut your grow light needs in half, but if you want to grow lots of Fig, you’ll still need one. For an introduction to grow lights, head over to our post on grow lights for indoor gardeners. We’ve also got a buying guide for screw in types, but to keep things simple in this guide, we’ll just provide directions for the 24W Screw in Bulb by Sansi, which we think is a good middle-of-the-road option.

How bright should your grow light be? 

Fig plants need the equivalent of 6+ hours of direct sunlight [DLI of 18+ mol/m²/day] to grow their best. In order to provide an equivalent amount with a grow light, it needs to be pretty bright! The 24W Sansi bulb should be placed 6 inches away from the top of the plant. This will give your PPFD (the standard measure of brightness) of 500 μmol/m²/s.

How many hours per day do your Fig plants need under a grow light?

Fig plants are known as “long-day” meaning that they develop faster with over 12 hours of light (and only need 6 hours of darkness to rest) so setting your timer to light your plants for 14+ hours is best. 

Fig Plants Need Warm Temps with an Annual Chill

Fig plants are native to northern climates and need to rest each winter – brought on by shorter days and colder temperature. Plants need to be in between 32°F and 45°F for 100 hours in order to internally build the cellular structures that will become fruits. When your indoor plant starts to lose its leaves in fall, place it outside for a few months until you meet the  “chilling requirement” (but bring them in if temps drop below 30°F for longer than a day). For the rest of the year, they are perfectly happy with a wide range of typical indoor temperatures. 

How to Prune Fig Trees

Pruning is important for Fig trees. Even dwarf varieties can easily grow up to 15 feet – and pruning keeps them easier to manage, care for, and fit in our living space. Beyond this, we help the plant focus its energy by limiting the number of branches we allow to develop. The basics of pruning are simple; plants grow from their tips (not bottom), but if you remove the tip it will redirect the growth to side branches. The art of pruning takes many forms, however – Bonsai, Espalier, and Spur are some ways the basic principles are applied. We encourage you to explore the look you want, but if you are unsure, open-center pruning is a well established style for fruit trees.

The standard for most fruit trees is known as “Open Center Pruning”  where the canopy consists of 3 or 4 evenly spaced main branches. This lets light and air penetrate through the center and reach the edges for an even, lush plant. Make the first cut when you are happy with the height of the trunk – it may happen as soon as you get your plant (we recommend letting the trunk be at least 2 ft above the soil). This cut should be right above a bud or branch coming off the main trunk. This will encourage the main branches to form, so if more than 3 or 4 come out then remove the extra with an eye to keep spacing even.  The main pruning is now done, so just once or twice a year you’ll want to do a maintenance prune to remove any crossing or dead branches and keep the center short.

Year 1+: How to Harvest Figs

You will know your figs are ripening when the skin will turn from green to a reddish-purple. Next, the figs will get softer to the touch – when they are soft and drooping down simply break the fruit away from the branch. Ripe figs go bad very quickly off the branch, so it’s best to eat them immediately!

Year 20+: End of Life

There are wild fig trees that are over 200 years old (and still producing!) so as long as you continue to provide your tree with good conditions your plant could outlive you!
