Chris created a plan to build a vegetable garden consisting of 5 tasks. The first task was to build a raised bed out of bamboo to contain the soil. The second task was to prepare the soil and create a compost pile using various organic materials. The third task was to plant different seed varieties, manage their growth through pricking and hardening, and transplanting them into the prepared soil. The fourth task was to make an insect repellent spray using rhubarb leaves and soap to address pests, and a liquid fertilizer from horse manure. The final task was to harvest the seasonal crops, preserve some through pickling and jam-making, and collect and store seeds for future plantings.
