Introduction:

Polycarbonate greenhouses are perfect for growing plants and vegetables year-round. The greenhouse comes with several features that provide the ideal environment for plants, such as insulation, natural light, and ventilation. Apart from these benefits, plants also require watering, which means that you'll need to know how to water your plants under the polytunnel row cover.

Why is watering important?

Watering is essential to ensure that plants grow healthy, and it is also responsible for ensuring that the plants produce flowers and fruits. Plants require different amounts of water depending on their species, age, and the environment around them. In a greenhouse environment, humidity is usually high, which means that the plants require less watering than in open soil gardens.

How to water plants under a polytunnel row cover:

1. Use an irrigation system:

A polytunnel greenhouse is a closed environment, and this means that you'll need to keep the humidity at optimal levels. Watering using an irrigation system is the best way to achieve this. You can choose from drip irrigation, overhead sprinklers, or misting systems.

2. Monitor your plants:

Each crop has different water needs, and it's essential that you monitor and adjust your watering schedule accordingly. The best way to monitor the water needs of your plants is to check the soil moisture level regularly. You can use a soil moisture meter or simply stick a finger into the soil; if it feels dry, then it's time to water the plants.

3. Water at the base of the plants:

Watering at the base of the plants is the best way to avoid getting water on the leaves, which can cause mold and diseases. It also ensures that the water reaches the plant roots and is absorbed effectively. Use a watering can or a hose with a sprinkler attachment to water at the base of the plants.

4. Use mulch:

Mulch is an excellent way to conserve moisture in the soil and reduce the need for frequent watering. It also prevents weed growth and adds nutrients to the soil as it decomposes. You can use organic mulch such as straw or leaves, or inorganic mulch like plastic sheeting or gravel.

5. Water early in the morning:

Watering early in the morning is the best time to water your plants because the temperature is cooler, and the humidity is usually at the highest. Watering in the morning ensures that the water has time to evaporate, and the leaves dry out before the temperature rises.

Conclusion:

Watering is a crucial aspect of plant growth, and it's important to get it right in a greenhouse environment. Using an irrigation system, monitoring your plants, watering at the base, using mulch, and watering in the morning are some of the ways to ensure that your plants get the water they need to thrive under a polytunnel row cover. With these tips in mind, you're sure to have a successful greenhouse gardening experience.
