How to Plant Cabbage: A Step-by-Step Guide

Cabbage is a nutritious leafy vegetable, it is an ingredient in some salad recipes and is cultivated due to its high demand, short growth cycle, and adaptability to various climates.

Here’s a comprehensive guide on how to successfully plant cabbage in Nigeria.

Description of a Cabbage Plant

Cabbage (Brassica oleracea var. capitata) is a leafy green, red, or white vegetable grown for its dense, leafy heads.

It belongs to the Brassica family, which also includes crops like cauliflower, broccoli, and kale.

Cabbage plants have thick, smooth leaves arranged in a tight rosette that forms a head.

Cabbage is rich in vitamins C and K and other essential nutrients.

Planting Season for Cabbage

In Nigeria, the ideal planting season for cabbage is during the cooler months, typically between October and February.

This period provides the moderate temperatures that cabbage needs to thrive.

Cabbage can also be planted during the rainy season in some regions, though proper water management is essential to prevent issues like root rot.

Planting Cabbage

To cultivate cabbage effectively, follow these step-by-step instructions:

Step 1 – Choose a Location

Cabbage requires a location that receives full sunlight, with at least 6-8 hours of sunlight per day.

Choose a site with well-draining soil, as cabbage is sensitive to waterlogged conditions, which can lead to root diseases. Ideally, the soil should have a pH level between 6.0 and 6.8.

Step 2 – Land Clearing and Preparation

Clear the land of weeds, grasses, and debris.

Tilling the soil to a depth of about 12-15 inches is recommended to ensure that the roots have enough space to grow.

Cabbage benefits from well-aerated soil rich in organic matter, so incorporating compost or aged manure into the soil during preparation can enhance fertility and structure.

Step 3 – Means of Propagation

Cabbage is generally propagated through seeds, though transplanting young seedlings from nurseries can also be effective.

Using seeds ensures genetic consistency and allows for better crop planning, while nursery-grown seedlings often have a faster establishment rate.

Step 4 – How to Plant Cabbage from Seed

• Nursery Preparation: To start cabbage from seed, prepare a nursery bed with fine, moist soil. Sow the seeds about 0.5 cm deep, spacing them 1 cm apart.
• Transplanting: After 4-6 weeks, when the seedlings reach about 4-5 inches in height, they are ready for transplanting. Plant them in rows, spacing each seedling 30-45 cm apart and allowing 45-60 cm between rows for optimal growth.

Step 5 – Watering

Cabbage requires consistent moisture, especially during the head-forming stage.

Water deeply, ensuring the roots receive moisture without over-saturating the soil.

In Nigeria, watering every 3-4 days in the dry season is often necessary, but adjusted based on rainfall and soil type.

Drip irrigation is ideal for water efficiency and helps to maintain steady soil moisture levels.

Step 6 – Apply Manure

Applying manure or organic compost is crucial for optimal cabbage growth.

During land preparation, mix well-decomposed manure into the soil to increase nutrient levels.

Once the plants are established, consider side-dressing with additional compost or a balanced fertilizer every 2-3 weeks to support growth.

Maturity and Harvest

Cabbage takes about 70-100 days from planting to reach maturity, depending on the variety.

You’ll know they’re ready for harvest when the heads are firm and dense, and reach a suitable size for the variety.

Harvest by cutting the heads from the base with a sharp knife.

Avoid pulling the plant from the soil, as this can damage surrounding plants.

Pests and Diseases

Cabbage plants are vulnerable to pests and diseases, including:

• Aphids: Small, soft-bodied insects that suck plant sap, causing wilting and stunted growth.
• Cabbage Loopers: Caterpillars that chew holes in leaves, reducing the plant’s ability to photosynthesize.
• Fungal Diseases: Diseases like black rot and downy mildew, which thrive in moist conditions, can cause leaf spots and decay.
• Root-Knot Nematodes: Microscopic pests that infect roots, causing swelling and impaired nutrient absorption.

Pest and Disease Control

• Cultural Practices: Practice crop rotation and avoid planting cabbage in the same spot every season to minimize soil-borne diseases.
• Organic Insecticides: Neem oil or garlic-based sprays can deter aphids and cabbage loopers.
• Biological Control: Introduce natural predators, such as ladybugs, to control aphid populations.
• Proper Spacing: Adequate spacing between plants helps prevent fungal disease by improving airflow and reducing humidity around the plants.

How Many Cabbage Plants Can I Grow on a 50 ft by 100 ft land and What Quantity of Cabbage Can I Harvest?

A 50 ft by 100 ft piece of land is approximately 5,000 square feet.

Using a common cabbage spacing recommendation of about 18 inches (1.5 feet) between plants within rows and 18-24 inches (1.5-2 feet) between rows, you can maximize the number of cabbage plants on this plot.

Here’s a breakdown:

1. Planting Density Calculation

• Row Spacing: 2 feet apart (to allow room for walking and tending to plants)
• Plant Spacing Within Rows: 1.5 feet apart

Using these measurements:

• Number of Rows: For a 50-foot width with 2-foot row spacing, you can fit about 25 rows.
• Plants per Row: For a 100-foot length with 1.5-foot spacing, each row can have approximately 66 plants.

So, 25 rows x 66 plants per row = 1,650 cabbage plants.

2. Yield Estimate

A single cabbage plant typically yields one head, with each head weighing between 1 to 2 kg under good conditions.

• Lower Estimate (1 kg per plant): 1,650 kg of cabbage
• Higher Estimate (2 kg per plant): 3,300 kg of cabbage

Therefore, from a 50 ft by 100 ft plot, you can expect to harvest between 1,650 kg and 3,300 kg of cabbage if growth conditions are optimal and you maintain proper care throughout the season.

Growing cabbage can be rewarding with the right practices.

By following this guide, from selecting a location to managing pests, you’ll be well-prepared for a successful harvest.
