Lettuce is one of the favourite vegetables for all those home gardeners, so lets make the growth better for these plants by discussing some of the Best Fertilizers for Lettuce. After radishes and little turnips, lettuce is one of the simplest crops to produce and one of the quickest to mature. Additionally, lettuce is a relatively light feeder; it doesn’t require a lot of fertilizer.
Having said that, lettuce grows quite quickly when fertilizer is present. Even better, you can observe the results for yourself by not fertilizing a few lettuce heads.
For lettuce, any balanced, all-purpose fertilizer will do, and those with more nitrogen (higher N value in the NPK values) will encourage quicker lusher growth. Similar to tomato fertilizers or grass fertilizers, there aren’t any “lettuce fertilizers” available on the market.
Although the majority of the fertilizers listed here are just general-purpose fertilizers, they have a few qualities that make them particularly effective for producing lettuce.
The Best Fertilizers for Lettuce for Greater Yield
1. Dr. Earth Premium Gold All-Purpose Fertilizer
One of the best commercially available organic fertilizers for the home gardener is Dr. Earth Premium Gold All Purpose Fertilizer, a mild, well-balanced fertilizer. The cause is that it’s one of the few commercial fertilizer brands with bacterial and fungal inoculation.
The ability of your plants to absorb water and nutrients is significantly increased by the mutually beneficial associations that some helpful fungi and beneficial bacteria form with plant roots. This is particularly crucial for lettuce since it matures very quickly. By adding more beneficial bacteria where your lettuce will develop, you can speed up the rate at which your lettuce will experience these advantages.
Dr. Earth fertilizer is 100% organic and contains helpful bacteria in addition to getting its nutrients from natural sources including alfalfa meal, fishbone meal, and feather meal. Additionally, it contains humic acids, which are often present in compost and help your lettuce absorb nutrients.
If applied as instructed, fertilizer with an NPK of 4-4-4 poses no risk of burning lettuce plants and contains all the macro- and micronutrients required for healthy growth. All of your vegetables can use Dr. Earth Premium Gold All Purpose Fertilizer, while there are superior solutions for tomatoes, peppers, and other heavy feeders.
2. Neptune’s Harvest Organic Hydrolized Fish & Seaweed Fertilizer
Fish emulsion is a tried-and-true fertilizer that is prepared from entire or leftover bits of fish (blood, guts, bones, and all) that have been ground into a strong emulsion for people looking for an organic substitute to traditional liquid fertilizers. This is what might be referred to as the contemporary application of the Native American habit of burying fish where crops are sown.
Technically speaking, Neptune’s Harvest Organic Hydrolyzed Fish & Seaweed Fertilizer isn’t a fish emulsion; rather, it’s fish that has been treated into a fully liquid condition or hydrolyzed. As a result, it functions as a liquid feed that acts immediately to accelerate lettuce development. Additionally, seaweed is added to this fertilizer, giving it a balanced nutrient profile and enhancing its already potent organic nature.
Neptune’s Harvest Organic Hydrolized Fish & Seaweed Fertilizer should always be diluted because its concentrated form will smell strongly of fish. When the container is opened, there is a very strong perfume, but when it is diluted and used in the garden, there is very little smell, according to customer evaluations with ratings of 4 and 5.

3. Down to Earth Organic Vegan Fertilizer Mix
Before, to achieve a balanced fertilizer without using any animals, you had to combine and match several fertilizers. However, options for gardeners who favor a vegan diet are starting to expand.
A “full spectrum” plant-based fertilizer was created by Down to Earth, a company with a large selection of natural organic fertilizers. It is made from a combination of plant-based ingredients like soybean meal, alfalfa meal, and kelp meal and is supplemented with minerals like rock phosphate and greensand.
Humic acids, which are vital for aiding plants in absorbing nutrients, are also present in Down to Earth Organic Vegan Fertilizer Mix. This fertilizer contains no by-products or products of animals.
The NPK is 3-2-2, which has the ideal ratio for leaf growth, plant metabolism, and a robust root system, but is low enough not to burn lettuce roots when used as instructed. The result is a potent, natural, vegan fertilizer that is excellent for all plants but is particularly beneficial for leafy green veggies like lettuce.
4. Miracle-Gro Water-Soluble All-Purpose Plant Food
When it comes to availability, usability, and effectiveness in a short amount of time, Miracle-Gro Water-Soluble All-Purpose Plant Food is the gold standard for liquid feed. This conventional liquid feed, while not organic, should be on the list because it is designed with all the essential nutrients and micronutrients for all plants.
Our liquid fertilizer must be dissolved in water before feeding it to your lettuce, unlike the other liquid fertilizers on this list, which are sold in solid crystal form. Although the Miracle-Gro formula’s high nitrogen content is ideal for producing lettuce and other leafy greens, it also provides enough phosphorus and potassium to support the growth of other crops in your garden.
Additionally, Miracle-liquid Gro’s plant food is designed with crucial micronutrients like calcium, manganese, iron, Sulphur, boron, molybdenum, and zinc, making it a full spectrum fertilizer that doesn’t need other additional nutrients.
Even though I prefer other fertilizers, I always keep Miracle-Gro available in case I need to give my crops a rapid boost or address a serious nutrient shortfall.
Try Neptune’s Harvest Organic Hydrolized Fish & Seaweed Fertilizer or Urban Farm Fertilizers All-Purpose Vegetable Fertilizer, both of which are listed in this article, if you want organic liquid fertilizer substitutes.
5. Jobe’s Organics All-Purpose Granular Fertilizer
An established brand in fertilizers, soil amendments, and other gardening supplies, Jobe’s now offers a comprehensive line of organic fertilizers with a patented formula of advantageous bacteria. Jobe’s Organics All Purpose Granular Fertilizer is the most well-balanced for growing lettuce.
Jobe’s Organics fertilizers are infused with advantageous microorganisms, much like Dr. Earth’s fertilizers. But in addition to helpful bacteria and fungi, Jobe’s Biozome also contains archaea. Without getting too technical, archaea have comparable physical characteristics to bacteria but have a considerably wider variety of metabolic pathways and the ability to break down materials that most bacteria cannot, such as minerals. Therefore, archaea, which account for up to 10% of all soil bacteria, are a crucial component of the ecology of healthy, fruitful soil.
All of the components in Jobe’s Organics All-Purpose Granular Fertilizer are derived from natural, organic, and sustainable sources. Feather meal, bone meal, processed chicken manure (fresh chicken dung must be composted or aged before it can be used as a fertilizer), and sulfate of potash are the only components besides healthy bacteria.
This fertilizer, which has a 4-4-4 NPK, can be used for all of your crops, flowers, trees, and houseplants, but it works particularly well for lettuce.
Consider using Jobe’s Organics All Purpose Fertilizer Spikes, which are also 4-4-4 but compacted into spikes that can feed your lettuce for up to two months, for an even more continuous release version.
6. Urban Farm Fertilizers All-Purpose Vegetable Fertilizer
For professional growers, Urban Farm Fertilizers has created a line of liquid fertilizers that are all built with organic ingredients and are designed to optimize harvests. Their plant food for greenhouses is designed to supply all the essential macronutrients and micronutrients for all types of vegetables and flowers, but it is particularly beneficial for lettuce.
The All-Purpose Vegetable Fertilizer from Urban Farm Fertilizers is organic and contains helpful bacteria. It has been infused with helpful bacteria and fungus that, when applied, will accelerate the breakdown of the organic substances. A complete range of minerals, humic acids, and enzymes are also included. Even hydroponic lettuce can benefit from the usage of urban farm fertilizers.
Customers who have used Urban Farm Fertilizers All-Purpose Vegetable Fertilizer have raved about bigger harvests in their gardens as a result of utilizing it.
The 4.5-2.5-6.0 NPK value is based on the most recent updated formula because Urban Farm Fertilizers frequently change the components of their fertilizers. One thing to keep in mind is that because this liquid fertilizer is highly concentrated, it must be diluted (256:1). 64 liters of liquid feed may be made out of a 1-quart bottle.
7. Burpee Natural Organic All-Purpose Granular Plant Food
Burpee has been a well-known company for over 144 years and is most recognized for its seeds, but they also make its fertilizers and soil enhancements. Even though Burpee Natural Organic All Purpose Granular Plant Food is not as well-known as other brand names, their nearly 150 years of experience in growing vegetables for the production of seeds means they are knowledgeable about the requirements for plants to thrive.
Though balanced for all veggies, its 4-4-4 formula is particularly effective for growing lettuce. If applied as instructed, this completely organic fertilizer is soft enough not to burn lettuce roots. Additionally, it has been infused with good bacteria to support a healthy soil environment for your lettuce plants.
Growing healthy veggies depends on soil life because it breaks down organic matter and forms bonds with plant roots that make it easier for plants to absorb nutrients and water.
Burpee even provides a 3-month money-back guarantee from the date of purchase, which is more than enough time to test it out on lettuce, which takes 50 to 80 days to completely mature.
8. Miracle-Gro Shake ‘N Feed All-Purpose Plant Food
The Shake ‘N Feed fertilizer range from Miracle-Gro is not only simple to apply, but also has the ideal nutrient balance for growing lettuce. It also offers the best of both worlds as a hybrid organic granular fertilizer: nutrients are readily available for lettuce to absorb, yet the organic components decompose gradually to continuously feed for up to 3 months.
Earthworm castings, kelp, bone meal, feather meal, and feather meal are the sources of organic ingredients. In addition to the primary elements of nitrogen, phosphorus, and potassium, it also contains the vital micronutrients of iron, zinc, and manganese as well as calcium, which is necessary for the development of strong cell walls in your lettuce.
Although this fertilizer is marketed as an “all-purpose” fertilizer, lettuce can grow quickly because of its NPK value of 12-4-8. While phosphorus and potassium are more critical for fruit/root development and overall plant health, nitrogen (the first number) is essential for leaf growth.
Try Miracle-Gro Performance Organics All Purpose Plant Nutrition Granules for a 100% organic substitute; it has a comparable NPK of 9-2-7 and is certified organic.
In this guide, you observe that During the primary growing season, liquid fertilizers should typically be administered every one to two weeks.
Spikes or grains of fertilizer that discharge slowly or continuously is used significantly less frequently. Depending on the individual brand, it could be every 4 weeks or every 3 months.
