When planting corn, the timing of seeding is crucial. The earlier the seeding, the higher the yield. Let's explore the best times for planting corn.
1. When to Plant Corn in Summer?
The ideal time to plant corn in summer depends on soil moisture. The optimal period for summer corn planting is from late May to early June. Planting during this time allows for harvesting in September to October. In Henan Province, harvesting typically begins in early June. Early summer planting ensures sufficient growing time and accumulated heat units. Additionally, in mid to late June, corn is in the seedling stage, with moderate temperatures and less rainfall, making it suitable for seedling emergence. As the corn enters the tasseling stage in July and August, its nutrient requirements increase. This period coincides with high temperatures and abundant rainfall, meeting the needs of corn at different growth stages.
2. How Many Days Does It Take for Summer Corn to Germinate?
The germination of summer corn depends on soil conditions. Under normal watering conditions, corn typically germinates in about 5 days. If there is a shortage of water, supplemental irrigation is necessary, which can delay germination by about 20 days. The optimal temperature for corn seed germination is between 25°C and 30°C. During the elongation stage, the daily average temperature should be maintained above 18°C. From tasseling to flowering, the temperature should range from 26°C to 27°C. In the North China region, corn should be planted promptly after the harvest of wheat or peas. The planting depth depends on soil moisture, ranging from 2.5 to 10 centimeters, with 5 to 6 centimeters being the most suitable.

7. Should I irrigate summer corn during germination?
Yes, ensure adequate soil moisture during germination by irrigating as needed, especially if there is insufficient rainfall.
8. How can I protect summer corn from pests and diseases?
To protect summer corn from pests and diseases, practice crop rotation, use disease-resistant varieties, and monitor for signs of pests or diseases regularly.
9. Can I use fertilizers for summer corn, and if so, when?
Yes, fertilize summer corn with balanced fertilizers during the growing season, preferably before planting and during key growth stages to support healthy plant development.
10. What are the signs of proper summer corn growth?
Properly grown summer corn should exhibit vigorous growth, with healthy green foliage, uniform plant height, and well-developed ears with filled kernels.
