When to Fertilize Fig Trees?

When to Fertilize Fig Trees

You know:

Plants can’t talk, they only show symptoms. So, you have to understand the plant needs to feed them. Yellow leaves, slow-growing, dropping lots of figs are the common sign of nutrient deficiency.

Moreover, sometimes figs need fertilizer regularly if they grow in sandy soil. Because sandy soil can leach out the nutrients.

So, how often to fertilize fig trees?

Here are the common rules that you should follow-

The growing season is the best time to fertilize. But don’t apply any fertilizer when the growing fig cuttings have no leaves. Let the cuttings emerge in spring and feed them thrice per year- in late winter, mid-spring and mid-summer.

But remember this:

You should add fertilizer when you understand that they really need it. Because over-fertilizing has some side effects. Over fertilized fig trees promote vegetative growth rather than fruit production. Thereafter, if the over-fertilized fig trees produce fruits, then it will drop at premature stages.

Also, stop feeding the fig trees before the first frost comes and after the figs form. Because the fertilizer promotes the new tender growth and frost can damage it.

How to Fertilize Fig Trees?

Before fertilizing fig trees, you have to determine how much fertilizer you need for your fig trees?

The required amount of fertilizer will vary depending on the types of fertilizer (i.e.: liquid, granular, spike) and the outermost circumference of the tree branches.

Generally, 1 ounce/28 gram fertilizer in a month is enough for 1-2 years old fig trees but older trees need more food. Feed older trees ⅓ lbs. of fertilizer for 1 foot of bush height.

This is the common rule but the amount will be different according to the composition and formula of fertilizers. That’s why manufacturers provide instructions and dosages for different plants and vegetables. You should read the label and follow the instructions.

Now; it’s time to fertilize the fig?

Dripping fertilizer too close can damage your fig tree. Make a circle about 1 foot away from the tree trunk and sprinkle the fertilizer just past the circle line. For potted fig tree, spread the fertilizer around the edge of the pot.

Don’t apply all the fertilizer in one place or on the base of the plant.

What is the Best Type of Fertilizer for Fig Trees?

You know different types of fertilizer available today. But what form of fertilizer can be best for figs? You can pick any form of fertilizer. Every form of fertilizer is compatible and best for outdoor and potted figs.

You have to just consider the ratio of nitrogen, phosphorus, potassium in the fertilizer. Generally, slow-release, organic and balanced fertilizer can be perfect for fig trees that have equal NPK number (for example 4-4-4 or 10-10-10)

But if your fig trees are at flowering and fruiting stages, you should pick that fertilizer containing lower nitrogen and higher phosphorus.
