Best Practices for Greenhouse Gardening

To make the most of your greenhouse, follow these expert tips:

1. Prepare the Soil

Healthy soil is the foundation of successful gardening. Test your soil regularly and add compost or nutrient-rich fertilizers when necessary.

2. Water Smartly

Overwatering is one of the most common mistakes. Use drip irrigation systems to keep soil evenly moist without waterlogging.

3. Manage Pests

Greenhouses can trap pests just as easily as crops. Regularly check plants for aphids, mites, or fungi, and address problems early.

4. Encourage Pollination

Some plants, like tomatoes, require hand-pollination in enclosed spaces. Electric brushes or simply shaking plants can mimic natural pollination.
