Frequently Asked Questions
#1. What Nutrients Do Holly Need?
Holly need 3 main nutrients to grow and blossom.
- Nitrogen (N) – This helps with root and steam growth and provides a firm base for the plant
- Phosphorus (P) – This helps with roots absorbing nutrients better
- Potassium (K) – This protects holly against diseases and helps with holly color.
Holly also need:
- Magnesium – Helps plants better process sunlight
- Sulfur – Provides holly with additional protein, which is needed for a strong life.
- Iron – Helps Holly have a strong base.
- Manganese – Helps holly growth and process of sunlight.
2. What is a NPK Ratio?
NPK stands for the ratio of Nitrogen to Phosphorus to Potassium.
Typically, holly need 3 pounds of nitrogen per 1,000 square feet.
For almost all holly you will want a fertilizer with a 10-10-10 or 5-10-10 NPK ratio.
3. How Do I Choose a Holly Fertilizer?
Choosing Holly Fertilizer will depend on what you want them to do.
- Bloom Boosting Fertilizer – This is good for blooming holly that die after a short amount of time.
- Strengthening Fertilizer – This is good for holly not budding. This will help holly absorbing water.
- Organic – This will not only help your holly but the soil around it.
4. How Do I Fertilize Holly?
If you want to fertilize holly there are several important tips you should follow:
- First, use a pH tester to ensure your soil is between 6.0-6.5
- Apply fertilizer according to the instructions on the label
- Use only water-soluble or liquid fertilizer and apply more frequently
- Use only liquid fertilizer for smaller holly.
- Watch the below video on how to fertilize holly
5. When Should I Fertilize Holly?
When you should fertilize holly depends on the holly you grow (annual or perennial), when the holly blooms, and the fertilizer you use.
- Always read the instructions for best use!
- Begin fertilizing when your holly after new green growth emerges from the ground or plant, but before flower buds begin.
- Apply fertilizer to your holly approximately 2 weeks after your last frost or right after new growth emerges.
- Stop fertilizing once flowers bloom and petals begin to fall.
6. How Often Should I Fertilize My Holly?
How often you should fertilize your holly depends on the fertilizer and soil.
- During the growing season (before holly buds appear) fertilize every 4 to 6 weeks.
- After your holly blooms and once petals begin to fall from the plant you should stop fertilizing.
Slow-Release Fertilizer does not need to be applied as much. Also, you do not need to apply fertilizer as frequently to loamy soil.
In addition, organic fertilizer does not need to be applied as much.
Liquid fertilizers should be applied weekly. You should also apply fertilizer more if you have sandy soil.
Finally, rotate your fertilize throughout the flower gardening season. This will provide the right amount of nutrient mix. Using only one fertilizer can potentially build up too much of one nutrient which will destroy your holly.
7. How Do I Know if My Holly Need Fertilizer?
You will know if your holly need fertilizer if you observe one of the following:
- Yellow leaves, no new growth, and small pale flowers mean your holly plants need nitrogen
- Dull foliage, falling leaves, and weak flower buds means your holly need phosphorus
- Weak stems, poor buds, yellow edges on leaves, or brown leaves means your holly need potassium
8. What Alternatives to Fertilizers Can I Apply to Holly?
If you do not want to use retail or commercial flower fertilizers then you can use the below alternatives. These alternatives will not only help your plant but the soil around it:
- Epsom Salt
- Kelp Meal
#9. What are the Different Types of Garden Fertilizer?
A) Granular
Granular fertilizer is a dry fertilizer that can be applied with a spreader.
One of the benefits of this type of fertilizer is that you can see the actual fertilizer. You can also see where you have applied it and where it needs to be applied.
This type of fertilizer can be slow-release or quick-release.
Slow-Release fertilizer releases nutrients steadily over an extended period of time. This means you only have to fertilize once or twice a year.
Quick-Release delivers nitrogen immediately.
B) Liquid
Another type of fertilizer for your garden is liquid fertilizer.
Liquid fertilizer needs to be diluted before it can be applied. It can be applied using a canister, hose, or a watering can.
It is easy to apply and is quickly absorbed.
C) Spikes
The final type of fertilizer that can be applied to your garden is spikes.
Spikes are fertilizer in the shape of sticks. This is a slow-release fertilizer meaning it will be released over time. It is directly inserted into the ground!
This is perfect for beginning gardeners.
#10. What’s the Difference Between Organic and Synthetic Fertilizer?
My next tip for deciding on the Best Gardening Fertilizer is simple:
- Buy either organic or synthetic fertilizer.
Synthetic fertilizer releases nutrients quickly
- This type of fertilizer comes in liquid, granular, or spikes.
Organic fertilizer releases nutrients slowly.
- It typically is not concentrated meaning that the odds of killing plants are much less.
Below, are my three favorite organic fertilizers.
