Covering your garden with plastic, also known as plasticulture, is a method used by gardeners to improve their yields and eliminate pests. The process involves laying plastic over the soil, which acts as a warming blanket, increasing the ground temperature and deterring pests. This technique is especially useful for those who want to get a head start on their planting, as it allows gardeners to plant their crops earlier in the year. Additionally, the plastic mulch aids in soil moisture conservation by preventing water evaporation and can help to kill weeds by excluding light and water. However, it is important to note that plastic sheeting should be thick and opaque to be effective, as thinner plastics may rip and degrade over time.

Using black plastic to kill weeds
Using black plastic is an effective and eco-friendly way to kill weeds without the use of herbicides or the need to till your garden. This method, known as solarization, involves placing a sheet of thick, dark plastic over the area you want to clear of weeds, weighing it down, and letting it suppress growth. The plastic creates a greenhouse effect by trapping heat and blocking access to water, eventually killing the vegetation underneath.
To use black plastic to kill weeds, start by mowing the grass and weeds as short as possible. Then, cover the area with black plastic sheeting, which you can purchase in a variety of thicknesses. Ensure that the plastic is thick enough so that plants cannot push through it, and that it is opaque to prevent light from reaching the weeds. Weigh down the plastic with bricks, large stones, or sandbags, especially in windy areas.
Black plastic kills weeds by depriving them of light and water, so it is important to ensure that your plastic sheet is securely anchored and that no weeds are protruding through it. You can further improve the effectiveness of this method by watering the soil before installing the plastic to encourage weed seeds to germinate. However, be aware that this method may be less effective in low spots that receive significant drainage.
Depending on the climate you live in, you may want to leave the plastic in place through the winter and spring seasons before removing it to plant your garden. In warmer climates, you may only need to leave the plastic in place for a few months. Once you remove the plastic, you will be left with cleared land that is ready for planting.

Preparing the garden for plastic covering
The next step is to water the soil before covering it with plastic. Moisture is necessary for weed seed germination, so watering the soil before covering it will improve the performance of this method. Water the soil until it is moist, to a depth of about 12 inches, before adding the plastic sheeting. It is important to note that this process will be less effective in low spots that receive significant drainage, as water can enter underneath the plastic from the edges.
After watering the soil, roll out the plastic sheeting and secure it in place. Begin by staking down one end of the plastic to the end of the row. Then, roll out the plastic and return to the start, staking down the other end. If using landscaping stakes, work your way a few feet down each side and shovel about 2 inches of dirt onto the outside of the plastic to hold it down and keep it tight. Alternatively, use bricks, large stones, or sandbags to weigh down the corners and edges of the plastic, especially in windy areas. Make sure to keep wind from getting underneath the plastic, as it may blow away.
When using plastic to cover your garden, it is important to choose the right type of plastic. The plastic should be thick, dark or opaque, and not allow light to pass through. This is because plants need light for photosynthesis, and if light is excluded, they will die. Clear plastic or thin plastic that allows light to pass through may not be effective in killing weeds and can degrade more easily. Black plastic is commonly used as it absorbs light and traps heat, creating a greenhouse effect that kills vegetation underneath.

How to secure plastic sheeting
Covering your garden with plastic sheeting is a great way to kill weeds and prepare your garden for planting. However, it's important to secure the plastic properly to ensure it's effective and doesn't cause any damage. Here are some tips on how to secure plastic sheeting:
Use Weights: One of the simplest ways to secure plastic sheeting is to use weights to hold it down. You can use bricks, large stones, or other heavy objects to weigh down the edges and corners of the plastic. This method is easy to set up and doesn't require any special tools or equipment.
Landscaping Pins: If you're covering a large area or want a more secure hold, consider using landscaping pins. These are long, sturdy pins that you stake into the ground through the plastic sheeting. They are designed to hold down landscaping materials, such as plastic mulch, and can be found at most garden supply stores.
Magnets or Hooks: For a more innovative solution, consider using magnets or hooks to secure the plastic sheeting. You can glue magnets to your garden bed or shed and then attach the magnets to the plastic sheeting, holding it in place. Alternatively, you can install eyes or hooks in your garden bed and use corresponding hooks or eyes on the plastic sheeting to secure it, similar to a hook-and-eye closure.
Cover with Mulch: While not a direct method of securing the plastic sheeting, covering it with mulch can help weigh it down and keep it in place. However, as mentioned earlier, be cautious when removing the plastic as the mulch can break down and make it difficult to pull up the plastic without it tearing.
It's important to note that plastic sheeting should be thick and opaque to effectively block light and kill weeds. Thin or transparent plastic may not be effective and can rip more easily. Additionally, be mindful of the potential drawbacks of using plastic, such as the negative environmental impact and the possibility of microplastics ending up in the soil.

Benefits of plastic mulch
Plastic mulch is a product used in gardening to suppress weeds and conserve water in crop production and landscaping. It is a type of inorganic mulch, made from polyethylene film, and comes in a variety of colours, including black, dark green, red, yellow, light blue, and clear.
One of the main benefits of plastic mulch is its ability to prevent weeds from germinating and growing. By blocking sunlight, plastic mulch smothers and kills weeds, resulting in less weed competition for plants and healthier crops. This saves gardeners from the taxing chore of daily weeding.
Plastic mulch also aids in soil moisture conservation. It traps moisture and heat, preventing water in the soil from evaporating and reducing the amount of water needed for irrigation. This is especially beneficial for plants that require adequate moisture to grow, such as fruit-bearing trees and plants producing vegetables.
Additionally, plastic mulch can protect plants from harsh weather and regulate soil temperature. Dark-coloured mulches absorb sunlight and warm the soil, allowing for earlier planting and faster growth. Conversely, white or light-coloured mulches reflect heat, reducing soil temperature, which can be beneficial for certain plants during the summer months.
Plastic mulch also helps prevent soil compaction and keeps ripening fruits off the ground, reducing fruit rot and keeping them clean.
While plastic mulch offers these benefits, it is important to consider potential drawbacks, such as the environmental impact of plastic accumulation in soils and the higher costs associated with its use compared to planting in bare soil.

Drawbacks of using plastic
Covering a garden with plastic is a popular method for clearing land and preparing it for a new garden. While it is an effective way to kill weeds and grass, there are several drawbacks to using plastic.
Firstly, plastic is not biodegradable and can persist in the environment for hundreds of years. It can eventually start to decompose, creating a mess and leaving microplastics in the soil, which are harmful to the environment. The plastic can also become brittle and difficult to remove, leaving plastic bits everywhere.
Secondly, plastic has zero breathability. It prevents water in the soil from evaporating, which can lead to oversaturated soil and potential disease issues such as fungal growth. This can be detrimental to plants with long roots that require adequate water.
Additionally, plastic film can be easily ripped by plants pushing through it, and it is often not reusable. It typically lasts for one season or less, creating more waste and contributing to pollution.
Furthermore, the use of plastic may not be necessary for certain crops. Cool-season crops, such as root vegetables, peas, spinach, and lettuce, do better without plastic covers as they thrive in cooler soil.
Overall, while using plastic to cover a garden has its benefits, it is important to consider these drawbacks and explore longer-lasting or biodegradable alternatives, such as cardboard or compost.
