- Apply our liquid fertilizer to the soil surrounding the base...
The liquid solution comes in a 16-ounce bottle, enough to get your flowers and veggies thriving. It comes with a garden feeder and a dosing spoon, very helpful in feeding with a watering can.
What you need to do is to attach the feeder to the garden hose. Then insert the refill bottle into the feeder and feed your plants as you water. Feel free to switch to the water setting by turning the dial.
On the negative side, this sprayer is rather not durable, requiring you to be extra careful not to break it.
It’s best to always keep it clean since the hole the fertilizer goes through is small and clogs easily.

A Detailed Buying Guide For Best Liquid Fertilizer
What Is Liquid Fertilizer?
A liquid fertilizer is a concentrated solution that feeds your plants instantly through the soil. It brings about visible results within a few days.
Nonetheless, long term treatments are necessary with this type of fertilizer due to the liquid base. Each feeding might last from 1 to 3 months, depending on your lawn care purposes.
Why Should You Use Liquid Fertilizer?
It ensures even distribution over the treated area. The spray bottle and the hose help you spray the plant food evenly, which is especially helpful in lawn care. The liquid fertilizer also can nourish plant roots more effectively.
Moreover, the liquid form allows you to dilute the fertilizers based on your needs. It means you can customize the plant food to feed the lawn most effectively, according to the soil structure, root strength, and so on.
The liquid lawn fertilizer is extremely easy to apply. Simply attach the bottle to a hose, and you are good to go.
How To Choose The Best Liquid Fertilizer
How large is your lawn?
Liquid fertilizers are ideal for large-sized lawns since they cost less while offering almost the same effectiveness as granular fertilizers.
Depending on the size of your lawn, you will choose the suitable amount of plant food. These fertilizers are often available in bottles that hold from as little as 16 ounces to 1 gallon.
Do you need instant results?
If yes, you should undoubtedly get a bottle of liquid plant food. It is the quickest way to correct vitamin deficiency and get your lawn looking lush and attractive in no time.
But in case your lawn is already healthy, and you only want some supplements, even the best liquid fertilizer may not live up to your expectations. Opt for granular instead if you want long-term maintenance.
Does your turfgrass have a weed problem?
Some multi-purpose fertilizers supply nutrients and control weeds simultaneously, for example, the Scotts Turf Builder above.
If you find weeds dominating your lawn, you may want to choose a 2-in-1 liquid fertilizer to recover your grass to its healthy self quickly.
Liquid Vs. Granular Fertilizers
Spatial Difference
This factor refers to the distance from the plant roots to nutrients in which absorption can take place.
In this case, the grass liquid fertilizer has an edge over its counterpart. It allows the plants to absorb the nutrients more effectively.
For example, phosphorus is a slow nutrient that has a hard time finding its way to the plant roots. The liquid form provides a solution to this problem since the nutrients are free to move along the soil.
Salt Content
Since the granular fertilizer provides a slow release, it needs to keep the nutrients for a longer period. This requirement results in high concentrations, and hence high salt content.
Young plant roots may find the fertilizer “hot” and steer clear from the nutrients. Thus, if your turfgrasses are young, you may need liquid fertilizer for lawns instead of granular.
Consistency
In liquid lawn food, each drop contains the same percentage of nutrients.
In contrast, the amount of nutrients are not always consistent with each dry pellet of granular fertilizers.

Frequently Asked Questions
Q: Which type of liquid fertilizer should I use: nitrogen or potassium?
A: Each nutrient serves a different purpose, so which one to choose depends on the condition of your turfgrass. For example, nitrogen’s main purpose is to achieve green leaves, while potassium’s is for flowers’ splendid blooms.
On top of that, there is phosphorus liquid plant food for well-developed roots. Meanwhile, magnesium, calcium, and sulfur will keep the foliage always healthy.
Q: How to use liquid lawn fertilizers?
A: The easiest and quickest way is to attach the bottle to the garden hose. Many products come with the attachments, for example, the Miracle-Gro.
Q: How much liquid fertilizer should I use?
A: The right amount depends on many factors, including the type of grass, your lawn conditions, and the fertilizer formula.
When applying the fertilizer for grass, make sure that you spray it evenly over the grass. Otherwise, you may end up with a patchy lawn, which consists of brown patches in some areas and lush blades of grass in others.
Q: How often should I apply liquid fertilizer on my lawn?
A: Generally, it is recommended to fertilize your lawn twice a year in spring and early fall. In spring, the plants need vitamins to grow lush and green.
On the other hand, the second application will supply nutrients to help the foliage survive the cold days. But if you find your turfgrass turning yellow, you can give them a quick boost of nutrients right away.
