There is optimal temperature, light / darkness, and moisture requirement for seed germination of plant species. Days to germination varies from a few days (e.g., lettuce, cucumber, corn) to four days (e.g., cabbage, watermelon, kale) to five days (e.g., cauliflower, spinach) to six days (e.g., bean, carrot, eggplant, onion, pea) to seven days (e.g., celery) to eight days (e.g., pepper) to 13 days (e.g., parsley, parsnip) under optimal conditions of temperature and moisture.
Crop rotation rotates crop species three year turn from leaf/stem crops (e.g. cabbage, broccoli, kale) to bulb/tuber crops (e.g., onion, potato, carrot) to fruit /seed crops (e.g., peas, corn, pumpkin, tomato, pepper). Lastly, there are perennial vegetable crops that come back every year such as rhubarb and chives, which have benefits with varying flowering time, extended seasons, and hardiness under suboptimal environment conditions.
