Fiddle Leaf Fig Nutrient Requirements

Soil alone won’t provide your fig plant with all of the nutrients needed to maintain its growth. Even incredibly rich soil will need to have nutrients supplemented, as they will be depleted as the plant grows.

Nitrogen

Similar to most other indoor household plants, fiddle leaf figs need nitrogen to help produce new leaves and maintain their foliage. When they don’t receive proper nitrogen supplementation, their growth will be stunted, and the plant will eventually weaken.

Phosphorus

Fig plants also need phosphorus to stimulate their roots’ growth, maintain vitality, and fight plant diseases. They use phosphorus to transfer energy throughout their roots, branches, and foliage–and it plays a key role in its metabolic activities. To effectively absorb phosphorus, the plant’s soil will need to have a pH between 6.5 to 6.8.

Potassium

Potassium helps the plant maintain its strength and gives it the ability to ward off diseases. It’s also responsible for regulating and maintaining metabolic activities.

Types of Houseplant Fertilizers

There are a few factors to consider before determining which fertilizer type may work best for your fiddle leaf fig plant. One important factor is the fertilization method that you want to use for your plant. Each method has its own advantages and disadvantages. There are three main types of fertilizers used for indoor plants: slow-release fertilizers, granular plant fertilizers, and liquid plant fertilizers.

Granular fertilizers

Granular fertilizer is ideal when you are re-potting your fig plant. This fertilizer works by releasing nutrients every time you water the plant, which is very beneficial, as it allows for them to be released slowly. One of the biggest setbacks with this type of fertilizer is that it can be challenging to control the fertilization strength (which is the biggest setback with slow-release fertilizers in general).

Slow-release fertilizers

This type of fertilizer typically comes in capsules or small pods and slowly releases nutrients into the plant’s soil. The biggest advantage of this type of fertilizer is that you don’t need to set any reminders to fertilize the plant, as it will keep it fertilized continuously. Slow-release fertilizers work best when fig plants are in smaller pots.

Liquid fertilizers

Liquid fertilizers are the easiest to use and control. To apply them, you simply need to dilute the fertilizer with water, add it to your pouring container, and apply it to your fig plant whenever it’s due for a feeding. This type of fertilizer is great in winter months when plants are more dormant, as you can lessen the amount of fertilizer that the plant receives simply by not applying it (unlike slow-release and fertilizers). However, the biggest disadvantage to this would be that you will need to set reminders to feed the plant on schedule. So if you’re someone who is out of town frequently or who tends to forget to feed your plant, this may not be an ideal option.

What kind of soil does fiddle leaf fig need?

Fiddle leaf fig plants thrive when they are grown in well-aerated, fast-draining soils. The roots of these plants prefer fairly dry soil (or moist) instead of wet soil–which can actually hinder their health and growth. Using poor soil for your fiddle fig leaf can cause problems with the plant’s roots aeration, and too strong soil mixes may burn your plant with chemicals or harmful salts. 

Do fiddle leaf figs like to be root bound?

Yes, these plants are content with being root-bound and typically do not need to be re-potted often. They can grow just fine when they fit snugly in their pots.

Do fiddle leaf figs like peat moss?

Fiddle leaf figs require a well-draining potting mix, and peat moss alone does not qualify as such, unfortunately. So while you can definitely add peat moss to your plant’s potting mix, using it as soil all by itself won’t fair well for your fig plant.

Do fiddle leaf figs like coffee grounds?

Many indoor growers attest to the benefits of coffee grounds to encourage fiddle leaf fig plants’ growth. So, it seems that there is truth to its benefit. However, it’s always best to introduce new ingredients slowly to your plant, as not to shock it. Coffee grounds are especially acidic, so it may be a good idea to first work a small amount into your compost before adding them.
