A well-balanced fertilizer is essential for plant health and maturity. It packs vital nutrients to kickstart the growth of your garden plants.
However, if applied in excess, fertilizers can become detrimental to your plants’ wellbeing.
Among the top-listed, all-purpose fertilizers for your plant development is Miracle-Gro.
Despite their effectiveness, gardeners in the past have cited their plants getting worse after the application of Miracle-Gro fertilizers.
This article discusses these fertilizers in-depth, their benefits to plants, and what to do in the event of excessive application. Keep reading!
What is Miracle-Gro?
Miracle-Gro is a family of fertilizer products produced by Scotts Miracle-Gro company. The fertilizer encourages the growth of your houseplants, and that’s the reason for its naming.
Otto Stern and Horace Hagedorn launched the Miracle-Gro brand in the 1940s. The brand has grown over the years to offer other beneficial products to gardeners, such as plant seeds, plant food, soil mixes, and soil revitalizers.
The All-Purpose Miracle-Gro fertilizer serves you best since you can add it to different plant types if you are a gardener. You can apply the fertilizer to trees, shrubs, vegetables, and flowering plants.
The fertilizer consists of three essential elements; nitrogen, phosphorus, and potassium. Typically, you will find them mixed in the ratio 15-30-15 for indoor flowers.
However, the ratio of nitrogen to other nutrients like phosphorus and potassium will differ depending on the houseplants you grow.
Here is a list of fertilizers from the Miracle-Gro brand that can best meet your plants’ fertilizer requirements.
- Flowers (15-30-15)
- Rose food (18-24-16)
- Tomato fertilizer (18-18-21)
- Trees and Shrubs (15-10-9)
- All-Purpose (24-8-16)
Knowing Your Plants Ideal Fertilizer Requirements
A common sign of your indoor plants lacking nitrogen is the yellowing of mature leaves and light green coloration.
If you spot green leaves having dark green veins, that’s a sign of potassium deficiency.
When the older leaves turn purple at the base with other leaves remaining dull and dark green, that is a signal for phosphorus deficiency.
When such nutritional deficiencies occur, most gardeners wonder how much fertilizer or Miracle-Gro is sufficient to combat them. No one answer fits all in this regard.
All you need to do is follow the instructions provided by Miracle-Gro regarding fertilizer amounts for the different types of plants in your garden. Miracle-Gro advises applying their fertilizer on a bi-weekly basis which is a safe interval for your plants not to get burned.
What Happens To Plants When Too Much Miracle-Gro Is Applied?
You may be tempted to add more fertilizer than is necessary to your plants, but that isn’t a guarantee for fast growth or more flower production. On the contrary, you risk burning the most sensitive parts of your plant with too much fertilizer.
The recommended amount is always a tablespoon of liquid that you need to mix with a given volume of water, which is usually a gallon. This amount is enough for 10 square feet of your indoor garden.
You can repeat this procedure if you have many plants around. Sometimes, you may apply an excess of fertilizer accidentally. This shouldn’t cause you sleepless nights.
The action isn’t going to kill your plants just yet; however, excessive application of Miracle-Gro systematically ends up burning your crops due to their inability to take in water.
Fertilizer is also salt, and too much of it could lead to the wilting of your plants. Overfertilization could also serve the opposite effect, that is, by decreasing the growth of your plants, making them weak and susceptible to pests and diseases.
Other signs of overfertilization you should observe in your plants include leaf scarcity or smaller than typical leaves, growth of short twigs, dead branch tips, and the need to prune your plant regularly.
How to Fix Excessive Application?
If you have been applying excess Miracle-Gro to your plants, you must now be wondering how to fix the problem?
There are multiple ways you can go about this, and we show you how through the steps below.
1. Remove Miracle-Gro From The Soil Surface
Luckily for you, Miracle-Gro is easy to spot when it’s above the soil surface because of its blue color. Use a small shovel to scoop chunks of soil from the ground surface that contain the blue product.
You should leave no trace behind since it gets watered down deeper into the soil, where it becomes difficult to remove it.
Ensure to use gloves if you have sensitive hands.
2. Flush Out The Miracle Product Remnants Using Water
Removing Miracle-Gro from the soil surface doesn’t solve the problem of too much of it entirely. Some of the product particles are still beneath the soil surface, and you will need to flush them using water.
If left underneath, they will continue damaging the roots of your houseplant further. You also want to be careful with house plants whose roots are sensitive to water.
You don’t want to be solving one problem while creating another. Too much water makes your houseplants susceptible to root rot.
Ideally, for this purpose, let the water run freely through your houseplant for upward of 30 minutes. Do this once and limit the waterings until your houseplant is sufficiently in need of water.
This helps prevent your houseplant from root rot. Most gardeners prefer using distilled water rather than tap water.
3. Get Rid of Damaged Leaves and Foliage
By now, most of Miracle-Gro should be out of your plant system. And the next place you should focus your efforts should be on the plant itself.
Check for wilted, burned, or damaged foliage. It’s an indication of the saltiness in your plant parts that has the potential to spread to other healthy parts.
Sterilize a pruning shear and get rid of all damaged, burned, or unhealthy plant parts.
4. Propagate Healthy Plant Parts
Not all pruned parts of your houseplants are to be thrown away. Much of these plant parts have leached out the excessive nutrients by now, which means you could propagate them into newer plants.
You could grow healthy plants out of a bunch of pruned plant parts.
5. Regulate Light Exposure
Too much salt in your plant tissue under sunlight increases the burning effect on your houseplant. To prevent your plant from deteriorating further, watch the light exposure.
To do this right, do not keep your sun-loving plant in the dark but provide it with artificial lighting set at a lower intensity.
Once the plant recovers and resumes its normal growth, you can return it to its usual place.
Miracle-Gro is an all-purpose fertilizer that gardeners love to use to encourage the growth of their houseplants.
The challenge is always using it in the right amounts, which makes some gardeners burn their crops.
If you have been having problems with Miracle-Gro, we believe you now have some answers to them.
The steps above help you correct excessive Miracle-Gro effects on your plants to help you revive the vigor and health of your garden plants.
