9 Best Fertilizers for Fig Trees That Really Work

When Fig Trees Don’t Require Fertilizer

Except when they are nutrient deficient, figs often don’t require the best fertilizer for fig trees. Compared to trees planted in the ground, trees housed in containers require fertilizer more frequently. 

Give your fig trees a slow-release, well-balanced fertilizer once in the spring and once in the fall, such as formula 10-10-10 or 8-8-8.

Interesting Facts About Fig Trees

  1. No flowers bloom on the branches of fig trees. The fruit has a blossom inside of it. Several tiny blooms produce the crunchy small edible seeds that give figs their distinctive texture. You pick figs when they are fully ripe and half-dried on the tree, following the cycles of nature.
  2. Figs naturally assist baked foods in retaining moisture, making them fresher.
  3. Numerous fig kinds grow in California, but the two most popular are the dark purple, sweet mission, and the amber-colored, somewhat nutty golden.
  4. 100% of the nation’s dried and 98% of its fresh figs grow in California.
  5. Early in the 16th century, the Spanish brought mission figs to the Californian region.
  6. Fig trees were first cultivated in California in 1769 by the missionaries of Mission San Diego. This is how the name “Mission” for the deep purple fig came.
  7. Many people think that figs, not apples, were the real fruit that Adam and Eve were eating in the Garden of Eden.
  8. Figs were a common training snack for the early Olympians. Figs were the first Olympic “medal” and the best award to the winners.
  9. Figs were a healing food in ancient Rome. They gave young people more strength, kept the elderly healthier, and made them look more youthful with fewer wrinkles. 
  10. The fig tree represents fertility, sweetness, and abundance.
  11. One-half cup of figs contains the same amount of calcium as one-half cup of milk.
  12. Figs have more fiber per ounce than prunes and more potassium per ounce than bananas.

How to Care for Fig Trees

Although figs can produce multiple phases of harvest at once, in the UK climate, just one crop typically ripens in September or October. The next production of figs will be the next year from the small, pea-sized embryo that develops in the autumn.

In the UK climate, figs you plant in the spring and early summer may not ripen by October. They will still grow but won’t ripen. Remove them in the late fall.

Fig trees may need protection in some regions during the winter, particularly if the tree is young. Cover your tree with horticultural fleece once the leaves fall, or if your tree is fan-trained, pack straw around the branches. Move the fig trees in pots into a cool shed or other spaces with covers, such as a greenhouse.

Remove the cover in the spring, feed the tree well, mulch with well-rotted manure, or replant potted figs outside. Every two to three years, repot fig plants that are in containers. When the tree grows too big to transplant, scrape as much compost as you can from the surface and refill it with fresh.

Train figs against the wall using horizontal wires while tying the stems together to form a fan-shaped formation. To promote development lower down:

  1. Pinch half of the developing points on the fan’s primary frame in the early summer.
  2. As the fresh shoots emerge, tuck them in.
  3. Remove any dead or crooked stems in the late winter to retain the tree’s open framework.

You can use similar pruning techniques on fig trees planted in containers, such as cutting weak and dead branches in late winter and fresh shoot tips in summer. You must regularly prune yearly to keep them under control because they are also very vigorous. You can cut your tree back severely if it is outgrowing its space, but keep in mind that you will temporarily lose fruit.

Pruning fig trees in the spring can make them bleed sap, which weakens and sometimes even kills the tree. Wear gloves because the sap from figs irritates the hands.

When and How to Fertilize Fig Trees

When you plant in nutrient-rich soil, constraining their roots and with lots of sunlight, fig trees require relatively little care in terms of feeding. However, not every fig tree can enjoy such luxuries, so it will require an extra infusion of nutrients to help it flourish.

Fertilizing Fig Trees

Before you begin any process, always take the time to read the label of the fig tree fertilizer you are using, whether you decide to use liquid fertilizer, granules, or spikes. As with all fertilizers, keep fertilizer away from the fig tree’s trunk to prevent disease and fertilizer burn.

Apply the proper amount of fig fertilizer to the soil close to the dripline instead. It will be necessary to work granules into the ground gradually. Activate the fertilizer by giving the area a good soak in water. To stop water from flowing away from the fertilizer application zone, scrape some soil around the region.

Fig Tree Fertilization Season

You will need to fertilize your fig tree in the early spring to kick off the growing season if the soil in which it is currently is relatively deficient in nutrients. Fig trees require regular feedings of high-dose potassium fertilizer, regardless of the type of soil they are growing in.

It is not advisable to fertilize in the fall since it can promote the development of fresh fruit that might be vulnerable to frost in the winter. In the autumn, cover fig trees with a heavy layer of mulch. This will assist in resupplying nutrients that they lose during the growing season.

Fig Tree Fertilization Schedule

Use a high-quality, slow-release fig fertilizer in the spring to boost the soil’s nutrients since this will make the soil better for your fig tree’s roots to absorb. Here, fertilizer spikes are advantageous because they provide a consistent flow of nutrients for up to 8 weeks.

As the growing season develops and your fig tree starts to bear fruit, switch to a granular fertilizer for figs with a high potassium content. Using grains over liquid feed can help you track how much you are using and ensure you are not overwatering simultaneously. Although fig trees can tolerate some drought, too much moisture can cause fruit to split or fall off.

How to Harvest More from Fig Trees

It’s wonderful to hear that the fig harvesting season is well underway. However, their limited shelf life makes fresh figs challenging to find in supermarkets. Only dried figs are typically available in supermarkets; while still excellent, they lack the allure of freshly plucked figs.

Fortunately, figs are one of the easiest fruits to cultivate inside or outdoors in a container at home. Here are a few insider tips to guarantee an abundance of big, delicious figs.

Your fig trees need as much sun as possible to produce huge, delicious fruit. Although fig trees can take some shade, placing them in full sun will yield the best results. When it’s warm outdoors, move container trees outside to sit in the sun; otherwise, place them beside a big, bright window.

You can use burlap to protect your tree from frost in the winter. Spread some insulating material around the bases of your trees to keep the roots warm, such as mulch or pine straw. Remember that since fig trees are tropical plants, they prefer warmth.

Fig trees prefer to be dry as well. Place your tree away from areas that frequently flood or have standing water. Fig trees prefer to stay dry in the winter and fall but will require additional water during the growing season. 

Every several days, check on your soil. It’s time to give your tree more water once it’s dry, which should be around 2 inches ( 5.08 centimeters) below the surface. Without soaking, the soil should be wet. Frequently, trees growing in containers dry up more quickly than ones rooted in the ground.

Except in cases when they are nutrient deficient, fig trees often don’t require fertilizer. When compared with trees growing in the ground, trees in containers need fertilizer more frequently. Give your fig trees a slow-release, well-balanced fertilizer once in the spring and once in the fall, such as formula 10-10-10 or 8-8-8.

What to Look for in Fig Tree Fertilizer


Every plant requires a particular combination of these nutrients, so be sure to choose the best fertilizer for fig trees with the proper mix of nitrogen, phosphorus, and potassium.

On fertilizer labels, look for a series of three digits to determine the ratio of these nutrients. For instance, the label of a fertilizer that contains 3% nitrogen, 5% phosphorous, and 6% potassium would read 3-5-6.

N-P-K are essential nutrients and are the main components that plants and trees require. It takes nitrogen to start healthy growth. The nutrient is also in charge of giving the fig leaf its lovely form and color. Your fig tree needs phosphorus to use and store energy effectively and assist with normal growth.

A fig tree needs potassium during its growing season in particular. That crucial fruit production is with the assistance of potash, which also guards the tree and its fruit against infection and illness.

Liquid Vs. Granular Fertilizer

There are many different types of fertilizers. Fertilizer granules and liquid fertilizers are two alternatives. The state of your garden and your intention to use the fertilizer determines your decision.

Granules are an excellent option because some gardeners prefer to see how much fig tree food they use. To fertilize a tree, estimate how many granules you’ll need following the area or size of the tree, then spread them around the trunk or stem on the ground. Typically, you need to bury granules and then water. The active components can then begin to work. 

You can buy liquid fertilizer either as a ready-to-use mix or as a liquid you have to dilute with water before using. There is a quick release of nutrients, which quickly begins to operate in liquid form. When your fig trees require frequent fertilization, especially after the fruit begins to form, liquid fertilizer is a fantastic choice.

Fertilizer Spikes 

Fertilizer spikes are solid, pre-measured spikes that you can insert into the ground. Since the manufacturer calculates the nutrients beforehand, some gardeners prefer spikes because you can never unintentionally use too much fertilizer or nutrients. They provide a clean, slow-release fertilization option.

Water-Based Fertilizer

Liquid fertilizer is one of the most popular ways to apply fertilizer to your plants. This may be more expensive than granular feed, but it has disadvantages because frequent fertilization may lead to overfertilization.


Granular fertilizer for fig trees is more affordable when you buy it in large quantities. Being resistant to severe temperatures makes it easier to store as well. If there is a need for nutrient correction, it is a useful technique to introduce nutrients at the onset or end of the season because it releases slower than liquid.

It isn’t as simple to use as liquid fertilizer, though, and it can occasionally be difficult to apply it uniformly as you can with liquid fertilizer.

Organic Vs. Synthetic

There’s the use of chemicals when producing artificial fertilizers. Although they are frequently more powerful and effective than their organic counterparts, they typically do not include any natural elements. If there is no proper utilization, they can harm the environment. Natural components like microorganisms and organic materials make organic fertilizers.

Both types have advantages and disadvantages. You frequently get a target product when using synthetic. However, if you go beyond, your plants could burn and perish. If you follow the manufacturer’s directions, organic fertilizer for fig trees offers a better option and is unlikely to harm the environment or your plants.

Wrapping up on The Best Fig Tree Fertilizer

Fig trees are slow-growing, low-maintenance trees. These adaptable trees require fertilizers at some point, just like other plants do. However, overfertilization can also harm them. Therefore, it requires attentive observation to know when to feed them and use the best fertilizers for fig trees, like our best choice Dr. Earth Natural Wonder Fruit Tree Fertilizer.

For fig trees with stunted growth and deficiency symptoms, planted in a site surrounded by other plants, a balancing ratio NPK fertilizer, such as 8-8-8 or 10-10-10, gives necessary nutrition. The three numerals, or NPK, stand for fertilizers with the lowest amounts of nitrogen, phosphorous, and potassium.

Depending on the brand’s “secret” recipe, each fertilizer has a unique set of NPK. Since each manufacturer wishes to protect their formula from competition duplicating them, the NPK is not always the real value for each recipe.

Fig trees are both fruit-bearing trees and aesthetic plants. Most gardeners grow their fig trees indoors as aesthetic plants, using less fertilizer only when necessary. Knowing when to fertilize fig trees is crucial because over-fertilizing them may also be harmful. Read our article and find out 9 of the Best Lawn Fertilizers for Summer Months.
