Starting Soybeans Indoors
In Wisconsin (Zone 5a-6a), begin indoor soybean seed starting from April 15 to May 10. This timing allows for healthy seedlings that can be transplanted outdoors from late May to early June after the danger of frost has passed.
Transplanting Soybean Seedlings
Transplant soybean seedlings outdoors between May 25 and June 10, ensuring the soil temperature is consistently above 55°F. Space the seedlings 2-4 inches apart in rows with 30-36 inches between rows for optimal growth.
General Care and Maintenance
Watering
- Provide consistent and deep watering to maintain evenly moist soil. Wisconsin’s variable climate necessitates regular monitoring to prevent dryness, especially during flowering and pod development.
- Water at the base of plants to avoid wet foliage, which can encourage fungal diseases.
Fertilizing
- Apply a balanced fertilizer at planting and follow up when the first pods appear. Incorporating compost before planting can improve soil fertility and water retention.
Pest and Disease Management
- Regularly check for common pests such as soybean aphids, corn rootworm, and diseases like powdery mildew. Pest management is crucial for maintaining healthy soybean crops.
- Utilize organic and integrated pest management practices to combat pests and prevent disease outbreaks effectively.
Harvesting
- Harvest soybeans when the pods are firm and the plants have begun to yellow. Regular harvesting ensures maximum yield and quality of beans.
The importance of good soil
Before starting to grow it is important to take a step back and find the condition of the soil in your garden,The optimal soil is a blend that includes the mineral-rich dirt along with organicrich organic matter that plants need to thrive.
In my garden I try to compost as mutch as possible, so I can mix in the nutrient ritch compost in my soil. I use both hot composting of food scraps and cold composting of all organic garden “waste”..
If you dont have the time or space for composting, it is possible to get compost ready to use in garden centers and Community Composting.
You can read more on Community Composting here: https://www.epa.gov/sustainable-management-food/community-composting
If you are uncertain of the quality of your soil, you can get easy to use soil tests at amazon for 17 dollars. Check latest prices here: Soil testing kit.
Also remember to check out how much sunlight your growing area gets, and that the rain drains well. If you treat your soil well and plan you crops according to your climate you will succeed with any plant you want.
The satisfaction when you harvest your own produce is well worth the time you put in 🙂
