What Are The Best Fig Tree Fertilizers? – Reviews and Top Picks (2023)

Fig trees are low-maintenance slow-growing trees. Like other plants, these versatile trees need nourishment from fertilizers at some point. 

However, overfertilization can also harm them. So, it takes a keen eye to know when to feed them and provide the best fig tree fertilizers in the market. 

A balanced NPK fertilizer, like 8-8-8 or 10-10-10, provides enough nourishment for fig trees with stunted growth, shows signs of deficiencies, or planted in a location surrounded by other plants.

The three numbers or the NPK represent the lowest nitrogen, phosphorus, and potassium content of fertilizers. 

Pro tip: Each fertilizer has a different set of NPK depending on the ‘secret’ formula of every brand. The NPK is not the actual number for every formula as every manufacturer wants to keep their formula to themselves to prevent the competitors from copying them. 

Fig trees are classified as both ornamental plants and fruit-bearing trees. As an ornamental plant, most gardeners grow their fig trees indoors which requires less fertilizer and applied only if they need it. 

Since over-fertilization can also harm your fig trees, it’s essential to know the problems that don’t really require fertilizer. 

These include:

  • Fig tree fruits that don’t seem to ripe as expected is a sign of overfertilizing them. 
  • Drought or lack of enough water supply makes fig trees bear immature fruits.

Also, fig trees love sun. So, if they’re showing some unhealthy signs, better reassess factors such as not enough water and sun before you head on to using fertilizers.

If nothing works and your plants still look unhealthy then it’s time to look for fertilizers to feed them.

In this post, we listed the 9 best fertilizers for fig trees in the market. We also provide the pros and cons to help you choose the best choice without going through the trial-and-error phase of using different brands of fertilizers.

Plant Care

  • Consider growing fig trees in containers and indoors when the temperature reaches -12 degrees Celsius.
  • If you’re planning to plant outdoor fig trees, make sure that you live in Zone 8 or warmer zones.

  • Regular watering is required in young figs once a week.

  • The sap of fig trees can irritate your skin. So, make sure to use gloves and a long-sleeved shirt when it’s harvest time.
  • Young fig trees are not strong enough for cold winters compared to mature fig trees. Make sure to keep the young fig trees indoors to overwinter them in pots until they have a stronger root system to survive the extreme weather conditions.
  • Prevent young figs (2 to 5 years old) from dying by choosing a good location where they won’t compete for nutrients in the soil and they get plenty of suns. You must also do the right preparation such as applying mulch and soil conditioning.
  • Fig tree roots are invasive so it’s best to plan before planting them. Otherwise, you can build root-retaining walls to keep the roots in place. Strategize a good location if you’re planting Brown turkey fig trees as they are more invasive than Celeste.

Tips in Fertilizing Fig Trees 

As you nourish your fig trees with fertilizers, here are some tips to avoid misuse and end up with dead plants:

  • Make sure to fertilize trees that are placed in sandy locations and surrounded by other plants that compete with the soil nutrients in their location.
  • Adding compost, liquid seaweed or manure tea can be enough as a fertilizer for fig trees. You may also apply seaweed extract every month during the growing season. This tree, like other plants, can grow well in soil with plenty of organic material.
  • Fig trees planted in containers need more fertilizers than those planted in the ground.
  • Overfertilization results in: 
  1. Less and unripe fruits
  2. Increased susceptibility to cold weather damage
  3. Growth spurt 
  4. Splits and cracks in trunks and branches
  5. Unripe fruits will fall and might take 3 to 4 years of recovery
  • Fertilize fig trees only when they show slow growth and pale leaves. If figs are still less than 12 inches in height after the growing season, it needs a boost from a fertilizer that should be applied in late winter or at the end of mid-summer
  • If the fertilizer is too strong you may divide it into smaller batches so you won’t overfeed your plants. 
  • Ideally, one to two-year-old fig trees require an ounce of fertilizer for a month when the leaves start to grow.
  • Mature fig trees don’t need much fertilizer and can survive using a third of an ounce of fertilizer per foot of tree height during late winter, mid-spring, and summer.
  • Don’t fertilize if the fruits don’t mature because it’s due to drought and not lack of nutrients. Adding fertilizer for this problem can do more harm than good to your fig trees.

Final Thoughts

Consider fertilizing fig trees in an as-needed approach. They’re one of the easiest plants to grow as they don’t demand too much water and intricate care. However, they need a lot of sunlight to be in their best health. So, make sure to place them in a sunny area during spring and summer.

    • Hi Frank,

      An inch of water is measured based on the depth of water above the soil when watering. To easily check if you reached the right levels, you can use a measuring line using a small stick. Place the stick on the soil and measure a one-inch distance above the soil surface and mark it with a pen or tie it with a ribbon. So, when you water your plants it would be easier for you to see your watering limit. You may want to make sure that the soil is fully drenched before it reaches the limit.

      Hope that helps!

      P.S: There’re 2 tools to convert 1 inch of water:
