Light
Corn is a warm-season crop that requires full sun exposure and warm temperatures to thrive.
Temperature
Once established, corn is relatively tolerant of high temperatures and can grow in a wide range of temperatures between 60 and 95°F. However, it may suffer from heat stress when temperatures consistently exceed 90°F during the daytime.
Pruning
Corn does not require pruning as it grows in a natural, untrained form.
Cleaning
Not needed
Soil
Corn is usually grown in the ground and doesn't require repotting. However, it is important to choose the right soil for growing corn, which should be fertile and well-draining with a pH of 6.0 to 6.8.

Life cycle
The life cycle of corn typically takes around 75 to 100 days, depending on the variety and environmental conditions. Here are the different stages of corn's life cycle:
Germination: Corn seeds germinate in about 5-12 days after planting.
Vegetative growth: During this stage, the plant produces leaves, stems, and roots. This stage lasts for about 50-70 days depending on the variety.
Reproductive growth: This is the stage when the plant develops its tassel and ear. This stage lasts for about 18-24 days.
Pollination: Corn is wind-pollinated, and the pollen is released from the tassel and lands on the silks of the ear, which then develops into kernels. Pollination usually takes place about 2-3 weeks after the tassel emerges.
Grain fill: This is the stage when the kernels begin to fill with starch and sugars. This stage lasts for about 20-30 days.
Maturity: The corn reaches maturity when the kernels are fully developed and the husks turn brown and dry. This stage usually occurs about 100 days after planting for most varieties.
Harvest: Corn is ready for harvest when the kernels are firm and the husks have turned brown and dry. Harvest time can vary depending on the variety and environmental conditions but usually occurs in late summer or early fall.Propogation
Propogation time
Spring - early summer
Corn is usually propagated by planting seeds directly in the soil. The time for sowing seeds depends on the location and climate. In general, corn is planted in the spring, when soil temperatures reach at least 60°F (15.5°C) and after the last frost date. For most regions, this is between late April and early June. In warmer regions, corn can be planted earlier, and in cooler regions, later planting may be necessary.
Corn can also be started indoors 2-3 weeks before the last frost date in peat pots or other biodegradable containers that can be planted directly in the ground, to give them a head start. However, because corn is sensitive to transplant shock, it is important to handle the seedlings gently and transplant them carefully. It is recommended to transplant seedlings when they are at least 6 inches tall and have at least two sets of leaves.
The seeds should be planted 1-2 inches deep and 4-6 inches apart in rows that are 2-3 feet apart. After germination, thin the plants to 12-18 inches apart to allow each plant to have enough space to grow.
