Choosing the best fertilizers for cabbage is important as cabbage is a heavy feeder needing lots of nutrients to produce large Cabbage heads and leaves.
Today Cabbage is a commonly used vegetable around the world, but it originated from Southern Europe.
It has a fancy and long botanical name: Brassica Oleracea Capitata.
This cool-weather crop is a biennial meaning that it occurs every two years.
It should be grown in rich soil with a steady supply of moisture.
The University of Illinois states that the closer the cabbage plants are the smaller their heads will be.
It is a humble vegetable plant that gives you a huge harvest within a short period and is full of beneficial nutrients.
If your Cabbage crop has poorly developed or undersized heads, you should enrich the soil with a boost of nutrients using commercial or homemade fertilizers.
In this article, I’m sharing the best fertilizers for Cabbage available on the market.
Best Fertilizers for Cabbage
The best fertilizers for Cabbage have an NPK around 8-16-16 before planting. 2-3 pounds per 100 square feet are optimal. 4 weeks after transplanting choose a fertilizer with an NPK of 21-0-0. Measure 1/2 cup of fertilizer per 10 feet. Avoid using high nitrogen (N) after the heads are forming.
Cabbage grows best with a soil pH between 6.5 – 7.0 for the best nutrient intake and yield.

Mother Earth Season’s Choice Vegetable and Tomato Fertilizer – Best Overall Cabbage Fertilizer
This fertilizer is beneficial for almost every other vegetable growing in your garden.
It is crafted by horticulturists, chemists, and biologists using ingredients like blood meal, feather meal, fishbone, kelp meal, and magnesium sulfate.
With the NPK analysis of 4-5-6, it will surely supply all nutrients needed for vegetable growth. It even contains 5.5% calcium and 1% water-soluble magnesium.

It’s mandatory to follow the manufacturer’s instructions if you don’t want to burn the Cabbages.
It can be used in any type of growing medium, including raised beds, pots, soil, hydroponics, etc.
It comes in powdered form for easy application.
But growers have complained about the strong smell, which makes it difficult to use this fertilizer indoors.
I would highly recommend wearing a mask and gloves while applying this fertilizer mainly because the powder is fine like dust, so you might end up inhaling some of it.
But it also stinks, so you do not want any products left behind on your hands.
Pros

- Can be used indoor or outdoor
- Apply it during both the vegetative or flowering phase

Cons
- Has a stinky smell which increases after dissolving in water

Liquid Fertilizer
They are fast-acting and easy to apply compared to granular or solid fertilizers.
They ensure a uniform distribution of nutrients in the soil compared to other types of fertilizers but reduce the risk of fertilizer burns.
You have more control over the feeding with liquid fertilizer because the strength can be adjusted with dilution depending on the growth stage of your Cabbages.
Young seedlings require a mild dose, whereas mature Cabbages might benefit from a stronger dose.

Fertilizing Cabbage
Perform a soil test after preparing the soil for your Cabbages.
The test results will give precise information about the nutrients in the soil.
Fertilization is the key to a successful Cabbage crop.
Arizona University points out how important nitrogen (N) is for cabbage as any deficiency will lead to a lower yield.
The fertilization for Cabbage depends on the growth stage.
I have divided the growth cycle of Cabbages into multiple stages to help you understand at what all times feeding is required and why.
Stage 1
The first stage is basic or initial fertilization. This is carried out with soil preparation.
This is done to help your Cabbage seedling adapt to the growing environment faster, boost the soil fertility and enhance the soil structure.
Stage 2
The next stage is the seedling stage.
Feeding young seedlings not only improves growth but also increases the survival rate and resistance. Light feeding is preferred in this stage because you do not want to burn the young plant.
Stage 3
This stage refers to the cabbage’s actual growth period. Watering and feeding during this stage are crucial.
Go for nitrogen-rich fertilizers in this stage as it will help in moving to the next stage. Some growers believe that it will shorten the growth cycle of the plant.
Stage 4
You should again fertilize the Cabbage after it enters the rosette stage.
You have to top-dress the Cabbage using a fertilizer that has potassium and urea. This encourages the growth of flower buds.
Stage 5
This is the flowering or heading stage. Fertilize your plant during the early and middle stages of heading with regular feeding.
Once the Cabbage enters the final stage of heading, you should perform only light foliar top dressing.
Key Points about Feeding Cabbages
- Outdoor feeding should be continued until the heads are formed.
- If you have frequent rainfalls in your area, you will have to fertilize the Cabbage more often because the rain can wash away the nutrients from the soil.
- If you notice hollow, brown areas on the stems, your plant needs more boron. You can add boron as a foliar spray or place it on the ground.
- Cabbage has shallow roots, so any weed growth near this plant can deprive it of necessary soil nutrients. Avoid using plant food or fertilizers that have weed killers as this can damage the Cabbage plant. You can mulch the soil for weed control.
- Do not over-fertilize your crop once the Cabbage heads have started forming because that results in rapid growth. In most cases, over-fertilized crops have cracked or split heads.
- Do not let the fertilizer touch the Cabbage leaves. Else you will end up with fertilizer burns.
- Planting in sandy soil requires more feeding.
- Before using starter fertilizer, make sure you have at least one true leaf. Feed the plant with the starter fertilizer every week at half strength. You can increase the feeding frequency to twice a week when two or more leaves have grown.
- Your chosen fertilizer should also have a reasonable amount of phosphate as it helps in improving the resistance of the plant to drought or diseases.
It’s crucial to follow what the label tells you to do and use the dilution rates recommended by the manufacturer.
If you want to use a slow-release fertilizer, add it before planting. Make sure you till and mix the fertilizer in the soil well and do not leave any fertilizer particles sitting on the soil surface.
You can continue adding slow-release fertilizer later on in the season. But I prefer switching to a liquid fertilizer because that’s easier to apply and absorb in the soil.
Make sure you water the Cabbage well because moist soil is necessary not only for growth but also for nutrient absorption.
In fact, Cabbage is one of the thirstiest plants out there and needs about 1 inch of water every week for the best growth.
Nutrient Deficiencies for Cabbage
Following are the symptoms of different types of nutrient deficiencies. These points will help you in identifying the correct deficiency and treating the soil accordingly.
Nitrogen
Yellowing of older leaves is a common symptom of this deficiency.
The leaves will also start decaying. If you do not treat the soil for nitrogen deficiency, your Cabbages will not form any heads.
Phosphorus
Lack of phosphorus does not impact the color of the Cabbage leaves.
But it reduces the growth of the Cabbage.
Potassium
If the old Cabbage leaves start turning light brown or yellow, the Cabbage needs more potassium.
The leaves will also start curling upwards.
Zinc
The Cabbage leaves will have a pale yellow color and stunted growth. The symptoms of zinc deficiency are more obvious in winter.
Zinc’s essential for the structural functioning of enzymes. Soils with low organic content have less zinc, and some of it can be washed with rainfall.
Sulfur
The growth of the Cabbages is stunted (especially the heads) and slowed with this nutrient deficiency.
Your Cabbage can also develop brittle leaf tissues and becomes vulnerable to fungal infections.
Calcium
This is indicated by burnt leaf tips. The younger leaves are affected first, and if left untreated, your Cabbage might not develop any heads.
Magnesium
The main symptom for this deficiency is chlorosis in between leaf veins of the Cabbage.
The symptoms first appear on mature leaves, and there is a clear reduction in the growth of the Cabbage.
