Best Fertilizers For Elephant Ears & Growing Guide 2022 Edition

Last year the elephant ears in my garden struggled with several issues. The issues, with time, got so strong that my elephant ears started giving a dull sad look so I decided to find a solution for it.

The best fertilizer for Elephant Ears are ones containing the amount of nitrogen, phosphorus, and potassium (20-10-20).

Elephant ears usually need to be fertilized in the spring and fall so I decided to save your time and energy to find a solution even though I am a little late for fall. 

Elephant ears are grown in shady places so they need fertilizer more than any other of your outdoor plants.

Fertilizing Elephant Ears- Grower guide

Elephant Ears Growing Guide

Before starting a fertilizer hunt for your elephant ears you need to know their requirements first. Sometimes just following the right watering schedule fixes the problem. The soil test will answer most of your questions. And remember! The pot grew and in-ground plants have different fertilizing requirements so do consider this point while searching for an ideal option.

What’s the ideal composition?

An all-purpose fertilizer containing a significant amount of nitrogen, phosphorus, or potassium makes an ideal choice for elephant ears. Most gardeners look for 20-10-20 fertilizers for their elephant ears.

Slow release or granular fertilizer?

Water-soluble, slow-release for ground plants. As I have mentioned above elephant ears are heavy feeders they need nutrients at several stages of their growth. So the slow-release fertilizer is there to supply nutrients when the elephant ear is in need. But for pot-grown elephant ears, granular fertilizer is the most promising option. It keeps on supplying nutrients to all the needed parts of the plant.

When should you fertilize the elephant ears?

At the time of plantation- elephant ears generally need nutrients to grow and establish stronger roots but if the soil is rich in nutrients, it’s okay to skip fertilizing at this stage.

In spring-like most of the plants, elephant ears need to be fertilized in spring. Fertilizing in early spring encourages leafy growth and promotes rich green color.

In fall- roots of most plants grow in fall and fertilizing in these months assist in establishing a stronger foundation.

Once a month- it’s totally up to you but fertilizing at least once every month would help them glow.

What qualities a good fertilizer has?

A good fertilizer takes good foliage and root formation as its duty. It is non-toxic, environment-friendly, and kids/pets safe. And it serves as a guard for pesticides and spider mites etc. 

Use as suggested on the label

To reap the benefits of fertilizer use as suggested by the company. Over and under application would never be able to bring the desired results. Overuse is more dangerous than underuse as underuse just does not bring the result but over-application burns the plants. 

A piece of advice

Do not look for expensive or well-known brands, look for the solution to your problem. Each case is different so do a soil test, consult a professional or experienced gardener, and identify the problem. So will then be able to find a solution. And do not ever make a hasty purchase without reading a label in detail.
