Starting Soybeans Indoors

General Care and Maintenance
Watering
- Provide consistent watering to maintain evenly moist soil, especially during the flowering and pod-setting stages.
- Water at the base of plants to prevent leaf wetness and minimize the risk of fungal diseases.
Fertilizing
- Apply a balanced fertilizer at planting and during flowering stages to enhance plant growth. Soil tests can help determine specific nutrient needs.
Pest and Disease Management
- Regularly scout for common pests like aphids, bean leaf beetles, and root rot. Being proactive is key to a successful soybean crop in Illinois.
- Utilize integrated pest management (IPM) strategies to protect soybean plants from pests and diseases.
Harvesting
- Harvest soybeans when pods are fully formed and the leaves begin to yellow. Regular harvesting helps maintain quality and prevent spoilage.
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 organic-rich organic matter that plants need to thrive.
In my garden I try to compost as much as possible, so I can mix in the nutrient-rich compost in my soil. I use both hot composting of food scraps and cold composting of all organic garden “waste”..
If you don’t have the time or space for composting, it is possible to get compost ready to use in garden centers and 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 your 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 🙂
