In a post, Gardens Organization, I documented what we planted in the school’s spring garden and when we expected to harvest the various vegetables. The problem is that nothing grew. Nothing. We have a watering system that we knew was not as efficient as we wanted. but we didn’t realize how inefficient until we had months without any rain. Seeds don’t grow without water.
Late in the spring when it was obvious that we had a problem, the grade 5 students did a uniformity test as described by IFAS. Both classes calculated the amount of water collected in cups at 5 minute intervals for 20 minutes. The early morning class had a strong wind at the time of the test. The early afternoon class had a light breeze. The morning class found that some of the cups collected no water and others collected only a few mm. The afternoon class found that all the cups collected water but still only a few mm. at best. Our watering system was not efficient enough to provide moisture for the seeds to germinate.
The same system was in place last fall when we grew and harvested many vegetables from the garden, so we didn’t question the efficiency of the watering system. However, during the fall there were frequent and regular rains. We are discussing the possibilities of putting a better system in place for the next school year. One of the limitations is that the school garden is in an open area. I hesitate to install a micro irrigation system because I’m afraid it will disappear over the weekend or some evening, so something more permanently attached but efficient is needed.
