As the summer sun reaches its peak, many gardeners wonder if it’s too late to plant sweet corn. The answer is yes, you can plant sweet corn in July, but there are some important considerations to keep in mind for a successful harvest.
Why Plant Sweet Corn in July?
- Extended Growing Season: Planting in July extends the growing season, allowing you to enjoy fresh sweet corn later in the fall.
- Second Harvest: If you planted sweet corn earlier in the season, a July planting can provide a second harvest.
- Filling in Gaps: If you have empty garden space, sweet corn can fill in the gaps and maximize your yield.
Choosing the Right Variety
Not all sweet corn varieties are suitable for July planting. Choose early-maturing varieties that can produce ears within 60-70 days. Some recommended varieties include:
- ‘Early Sunglow’
- ‘Honey and Cream’
- ‘First and Sweet’
- ‘Silver Queen’
Preparing the Soil
Prepare the soil well before planting. Sweet corn prefers loose, well-drained soil with a pH between 6.0 and 6.8. Amend the soil with compost or manure to improve fertility.
Planting Time and Depth
Plant sweet corn seeds when the soil temperature reaches 60°F. Plant the seeds 1-2 inches deep and 6-8 inches apart in rows spaced 2-3 feet apart.
Watering and Fertilizing
Water sweet corn regularly, especially during hot, dry weather. Fertilize the plants every 2-3 weeks with a balanced fertilizer.
Pollination and Silking
Sweet corn is wind-pollinated. Plant blocks of at least 4 rows to ensure adequate pollination. Silking occurs when the female flowers appear at the top of the stalks. This is the time when pollination takes place.
Harvesting Sweet Corn
Harvest sweet corn when the ears are plump and the kernels are milky. Pull the ears down and twist them off the stalk. Remove the husks and silk and enjoy the fresh, sweet corn.
Tips for Success
- Plant in well-drained soil with a pH of 6.0-6.8.
- Choose early-maturing varieties.
- Water regularly, especially during hot weather.
- Fertilize every 2-3 weeks.
- Plant in blocks of at least 4 rows to ensure pollination.
- Harvest when the ears are plump and the kernels are milky.
