Starting Soybeans Indoors
In Pennsylvania (Zone 6a), begin indoor soybean seed starting between April 15 and May 15. This timeline ensures healthy seedlings ready for outdoor transplantation starting from late May to early June, after the last frost has passed.
Transplanting Soybean Seedlings

General Care and Maintenance
Watering
- Provide consistent and deep watering, especially during flowering and pod development stages to maintain evenly moist soil.
- Water at the base of plants to avoid leaf wetness, reducing the risk of fungal diseases.
Fertilizing
- Apply a nitrogen-rich fertilizer during planting if needed, as soybeans can also fix nitrogen in the soil.
Pest and Disease Management
- Regularly monitor for common pests like aphids and soybean loopers. Maintaining good airflow and proper spacing helps minimize disease risk.
- Implement organic or integrated pest management methods to protect soybean plants from pests and diseases.
Harvesting
- Harvest soybeans when the pods are firm and the beans inside have reached their full size but before the leaves turn yellow and drop.
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.

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 🙂
