To have strong and healthy vegetables, everything starts with preparing the soil. Before plant, it is essential to ensure that the soil is well-nourished and suitable for the growth of cabbages. In addition, adequate watering is crucial to keep the plants healthy.

Importance of Soil

Announcement

Well-prepared soil is the foundation for any healthy crop. Be sure to mulch and turn the soil well to create a favorable environment for your kale to grow. Here are some tips for preparing your soil:

  1. Organic Fertilization: Use organic compost to enrich the soil. This improves soil structure and provides essential nutrients.
  2. pH Test: Check the soil pH and adjust if necessary. Cabbages prefer a pH between 6.0 and 7.0.
  3. Crop Rotation: Alternate planting cabbage with other plants to avoid soil depletion.

Watering in the Right Measure

Maintaining soil moisture is vital, but be careful not to overdo it. Water regularly, but avoid soaking the soil. Some tips for efficient watering include:

  1. Watering in the Morning: Watering in the morning helps prevent rapid evaporation of water and reduces the risk of disease.
  2. Drip System: Consider using a drip system for more even and controlled watering.
  3. Mulch: Use mulch around plants to retain moisture and regulate soil temperature.

Protecting Cabbage from Caterpillars

Announcement

Even with all the care taken, caterpillars can still appear. They are brought in by butterflies, which lay their eggs on the leaves of the plants. To avoid this problem, the solution is to prevent butterflies from landing on the cabbage.

Using the Shadow Screen

Shade cloth is an excellent option for protecting your plants. Not only does it block out some of the sunlight, it also prevents butterflies from laying eggs on the leaves. Let’s explain how to use it:

Assembling the Structure

  1. Required Material: Shade cloth (which blocks 50% of sunlight), wood for the frame, nails or ties.
  2. Assembly: Make a frame with the wood around your cabbages and cover it with shade cloth. This will create a physical barrier against the butterflies.
  3. Fixation: Make sure the screen is securely fastened and that there are no gaps where butterflies can enter.

Application in Pots

If you grow your cabbage in pots, the procedure is similar. Use sticks to create a structure around the pot and cover it with shade cloth. This will effectively protect your plants. Here’s the step-by-step guide:

Announcement
  1. Rods: Place sticks around the pot to create a support structure.
  2. Shadow Screen: Cut the screen to the appropriate size and cover the vase, fixing it well to the rods.
  3. Settings: Make sure the screen is tight to keep out butterflies.

Additional Suggestions and Tips

  • Alternatives to Sombrite Screen: Any other screen you have available can also work. The important thing is to create a physical barrier.
  • Companion Plants: Plant herbs like basil and mint near your cabbage. They help to naturally repel insects.
  • Natural Inspectors: Include plants that attract beneficial insects, such as lacewings and ladybugs, which help control pests.
