Keep an eye on your plants’ growth and be prepared to act quickly once you see these small-sized heads appearing.
Techniques for Tying Up Leaves Around Developing Heads
To successfully blanche your cauliflowers, follow these steps:
- Gently gather several large outer leaves over the top of the developing head.
- Tie those leaves together using a soft string or plant tie – avoid anything sharp or abrasive that could damage the plant tissue.
- Ensure that there is enough space inside for air circulation without allowing direct sunlight exposure on the head itself.
You may need to adjust ties occasionally as both leaves and cauliflower head continue growing during this period.
Monitoring Progress After Blanching
After blanching your cauliflower plants, it’s essential to monitor their progress.
Check on them every few days and adjust the ties as needed to ensure proper growth without constriction.
The heads should be ready for harvest within 7-12 days after blanching, depending on the specific variety and growing conditions.
In addition to monitoring head development, keep an eye out for any signs of pests or diseases that may affect your cauliflowers during this time.
Promptly address any issues you encounter by following best practices in pest management and disease prevention.
Blanching your cauliflower heads is a great way to protect the developing head from sunburn and pests. Now, let’s move on to fertilizing your growing cauliflower plants for optimal growth.
