Understanding Indeterminate Tomato Plants

What Are Indeterminate Tomato Plants?

Indeterminate tomato plants are unique because they continue to grow throughout the season. By the end of the season, these plants can reach up to 20 feet in length. Under optimal conditions, they can grow 10-12 inches each week.

Creating Optimal Growing Conditions

In a greenhouse, we can control the climate and water supply, providing the perfect conditions for these plants to thrive. We also provide the necessary training and support to ensure healthy growth.

Training and Supporting Your Tomato Plants

Using Strings for Support

We grow our tomato plants on strings connected to a wire above the greenhouse. As the plant grows and reaches the wire, we lower and lean it to start anew.

Weekly Maintenance

Each week, our greenhouse work involves:

• Removing suckers
• Twisting the plant around the main string to keep it straight
• Removing some lower leavesFor beef tomatoes, we also count the number of fruits per cluster to avoid overloading the plant.
  

  Optimal Plant Density

  Maintaining the right plant density in the greenhouse is crucial. Optimal density ensures that light availability becomes the limiting factor for growth. By maximizing light, we can increase revenue per square foot.

  The Role of Light and Reflective Plastics

   

  Enhancing Light Availability

  To maximize light reflection, we use white plastics on the ground. This practice is common among seasoned growers and makes a significant difference in plant growth.

  Benefits of White and Black Plastics

  Using white-on-black plastic serves dual purposes:

• The white side reflects more light, enhancing plant growth.
• The black side acts like mulch, keeping the soil moist and creating a healthy environment for earthworms and microbial life.
  

  Creating a Thriving Microenvironment

   

  Promoting Soil Health

  Covered soil fosters a perfect environment for earthworms to thrive. By laying organic matter and compost regularly, we support a micro-ecosystem that benefits the plants.

  Maintaining Moisture and Protection

  The plastic mulch keeps the soil moist and protected, creating an ideal microenvironment for the beneficial organisms in the soil.
