How To Choose The Best Fertilizer For Banana Trees?
Fertilizers for banana trees are divided into three types: liquid, spike, and granular.
This factor doesn’t affect the volume of supplemental nutrients packed in a fertilizer unit. Instead, it’s a personal preference issue. Each type of fertilizer has its pros and cons. To determine which is suitable for your needs, take a look at the following comparison table:
Easy to reach the roots
Effortless to track the area that you’ve applied the fertilize
Easy to mix with other liquids, such as selective herbicides or pesticides
Not require any special tools
Easy to use
Able to adjust the dose
The simplest to apply
No risks of over-fertilizing as each spike is pre-measured
Easy to store
More effective for slow release
Easy to store
More affordable to buy in bulk
Prone to be affected by strong winds
Not last long, which means you have to fertilize your garden more frequently
Prone to separate if stored through the winter
Hassles of measurement
More expensive than other types of fertilizers
Might not distribute evenly
Hard to adjust the doses of nutrients to meet the changing needs of banana plants during the growing season
The plastic caps of spikes might litter the soil
High salt content, which is prone to causing plant burning
Require more work: after fertilizing your garden, you’ll have to water it
Not easy to apply them evenly
Require a spreader and water to get into the soil
Like other plant species, bananas need a good amount of N, P, and K for plentiful growth. So, when considering a fertilizer for this plant, pay attention to the percentage of each of these micronutrients.
While it is recommended to opt for a balanced fertilizer, take note that each growing stage of banana plants requires a specific fertilizer with a different formula.
For example, during the growing season, banana plants need a high nitrogen fertilizer. But when they start to bloom and produce fruit, you should feed them with a high phosphorus fertilizer.
Besides, the soil analysis will affect the choice of fertilizer formula. If it is lacking phosphorus, for example, and your banana plants are in their growing season, then you should choose a fertilizer with a high percentage of nitrogen and phosphorus.
Which Brands Make The Best Fertilizer For Banana Trees?
Ever heard of Miracle-Gro and Ortho brands?
It is owned by Scotts Miracle-Gro Company, the US longest multinational corporation - founded in 1868 - and also the world's trusted brand. Their primary product lines are garden and pest control products known for top effectiveness.
The Jobe’s Company
The Jobe’s Company is dedicated to producing home and garden products that help make gardening easier. They are one of the most reliable brands in North America and provide over 200 products.
A bit different from the two brands above, Wellspring Gardens specialize in providing young, hard-to-find starter plants at the lowest shipping costs. Fertilizers are their side products but are widely loved for eco-friendly and nutritious ingredients, along with great effectiveness.
When should I fertilize my banana tree?
You should fertilize your banana tree once a month during the summer. Bonus: An organic fertilizer with formula 10-10-10 is the best choice.
Is Epsom salt good for banana trees?
Yes, it is.
For spectacular growth of banana trees, try either of these blends:
- A slow-release fertilizer + 1T Epsom salt per gallon + a water soluble fertilizer
- 1T Epsom salt per gallon + a water soluble fertilizer
Apply every time you water the trees.
What nutrients do banana trees need?
Banana trees need potassium, phosphorus, and nitrogen to grow healthily.
How do you fertilize a banana plant?
If you use a dilute liquid fertilizer solution (1/2 strength), you can apply it to your banana tree with every watering.
If you use a slow-release fertilizer. Use 1-½ pounds of 8-10-10 every month. For indoor banana trees, utilize 1/2 of that amount. Dig the fertilizer in the area around the tree, then water it well.
How can I increase my banana production?
Applying the right fertilizer to your banana tree is an effective way to increase production. For the best results, it is recommended to fertilize 1/2-pound (formula 3-1-6) every 2 months, four to six times during the season.
Once your banana trees start bearing fruit, increase to 4-6 pounds of fertilizer.
