Strawberries are delicious and nutritious fruits that have numerous uses. They can be eaten fresh from the garden or put in smoothies. To ensure that strawberries bear maximum yield, farmers incorporate farming techniques such as plastic mulching. Plastic mulching is a method that has proven to offer numerous benefits for strawberry farming, from increased yields to weed control. 

In this blog, we will explore what is required for plastic mulching, how to install it, compare it with organic mulches, and delve into the advantages and disadvantages of plastic mulch on strawberry farming.

Key components required when installing plastic mulch

  1. Plastic Mulch Film: Plastic mulch film is the main component needed for installation. Choose a durable, UV-resistant film designed specifically for agricultural applications. The film should be available in the appropriate width to cover the strawberry beds effectively.
  2. Drip Irrigation System: A drip irrigation system is required to provide water directly to the strawberry plants while minimizing water waste. This system consists of drip lines or tapes, which are laid under the plastic mulch, delivering water and nutrients precisely where the plants need them.
  3. Securing Devices: These devices are required to put the plastic mulch in place. Staples or pins are commonly used to anchor the edges and corners of the plastic mulch film to the ground, preventing it from shifting or blowing away.

Here is a step-by-step guide to help you install plastic mulch effectively:

Step 1: Soil Preparation

Start by preparing the soil in your strawberry bed. Remove any weeds, rocks, or debris that may interfere with the mulch installation. Ensure the soil is well-leveled and smooth for proper contact with the plastic mulch.

Step 2: Irrigation Setup

Install a drip irrigation system before laying the plastic mulch. Lay the drip lines or tapes evenly across the bed, ensuring they are positioned where the strawberry plants’ root zones will be.

Step 3: Secure the Mulch

Unroll the plastic mulch over the prepared soil, making sure it covers the entire strawberry bed. Leave some excess mulch on the sides to secure later. It’s best to have an extra person help with this step to ensure the mulch is evenly laid.

Step 4: Securing the Edges

Secure the edges and corners of the plastic mulch to prevent it from shifting or being blown away. Use staples or pins designed for this purpose. Start at one end and work your way along the edges, placing the securing devices every few feet. Make sure the mulch is taut and properly anchored.

Step 5: Creating Planting Holes

Using a sharp tool or a specialized hole punch, create planting holes or slits in the plastic mulch. The spacing of the holes should correspond to the recommended spacing for your strawberry plants. Be careful not to tear the mulch while making the holes.

Step 6: Planting the Strawberries

Plant your strawberry plants through the holes in the plastic mulch, ensuring the roots are properly covered with soil. Gently press the soil around the plants to secure them in place.

Step 7: Mulch Maintenance

After planting, regularly monitor the plastic mulch for any tears, shifts, or damage. Make necessary repairs or adjustments as needed to maintain its effectiveness throughout the growing season.

Importance of plastic mulch on strawberry farming

Plastic mulch plays a crucial role in strawberry farming, offering several important benefits that contribute to the success and productivity of the crop. Here are the key reasons why plastic mulch is important in strawberry farming:

Controlling of weeds

One of the primary advantages of plastic mulch is its ability to suppress weed growth. By creating a barrier between the soil and sunlight, plastic mulch prevents weed seeds from germinating and competing with the strawberry plants for nutrients, water, and sunlight. This reduces the need for manual weeding or herbicide application, saving valuable time and resources.

It conserves moisture

Plastic mulch helps to conserve soil moisture by reducing evaporation. It acts as a physical barrier, preventing water from escaping the soil surface and maintaining a more consistent moisture level around the strawberry plants. This is particularly beneficial in dry or arid regions where water availability may be limited, allowing farmers to optimize irrigation efficiency and reduce water usage.

It regulates soil temperature

Plastic mulch can regulate soil temperature by trapping heat from sunlight. This helps warm the soil in the early spring, allowing for earlier planting and accelerating crop growth. It is especially advantageous for strawberry cultivation, as strawberries thrive in warmer soil conditions. Plastic mulch also insulates the soil, reducing temperature fluctuations and providing a more stable environment for the roots.

Prevention of diseases

Plastic mulch acts as a physical barrier between the strawberries and the soil, minimizing direct contact. This barrier helps reduce the spread of soil-borne diseases and pathogens, including fungal infections and soil-borne pests. By limiting contact with the soil, plastic mulch helps maintain healthier plants and reduces the risk of disease outbreaks.

Keeps the fruits clean

The use of plastic mulch creates a clean and stable surface for the strawberries to rest on during harvesting. The fruits remain elevated, preventing direct contact with the soil and reducing the chances of soil contamination or damage. This results in cleaner, higher-quality berries and makes harvesting more efficient and easier for farmers.

It extends the growing season

Plastic mulch can extend the growing season for strawberries by warming the soil and protecting the plants from early-season cold snaps. This allows for earlier planting in the spring and later harvests into the fall. By maximizing the growing season, farmers can increase their overall strawberry yield and profitability.

How to choose the right plastic mulch for strawberry farming

When selecting the right plastic mulch for strawberry farming, several factors should be considered to ensure optimal results. 

Choose a high-quality plastic mulch film that is specifically designed for agricultural use. Look for films that are durable, UV-stabilized, and have good puncture resistance to withstand outdoor conditions. Consider the thickness or gauge of the mulch, as thicker films generally offer better durability and longevity. Select a mulch color that suits your specific needs. Black mulch absorbs more heat, helping to warm the soil, while silver or reflective mulch can deter certain pests. It’s also important to choose a mulch that is biodegradable or recyclable to reduce environmental impact. 


Strawberry plastic mulching offers numerous benefits for farmers seeking to maximize their yields and optimize crop health. While plastic mulch provides superior weed control, moisture retention, and temperature regulation, it is essential to weigh the environmental implications and choose sustainable options.
