Starting Soybeans Indoors
In Hawaii, starting soybean seeds indoors is not typically necessary due to the warm climate. However, if you are considering it, you can begin planting seeds indoors anytime from January to April. This will ensure healthy seedlings ready for outdoor transplantation once the weather is consistently warm.
Transplanting Soybean Seedlings
Transplant soybean seedlings outdoors starting from April 15 to May 15. Ensure that the soil temperature is consistently above 70°F before transplanting. Space the seedlings 4-6 inches apart in rows with at least 30 inches between rows for optimal growth.
General Care and Maintenance
Watering
- Provide consistent and deep watering to maintain evenly moist soil. Hawaii’s tropical climate may require more frequent watering during dry spells.
- Water at the base of plants to avoid excessive moisture on leaves, which can lead to fungal diseases.
Fertilizing
- Apply a balanced fertilizer at the time of planting and during the early flowering stage to encourage healthy growth and pod formation.
Pest and Disease Management
- Regularly check for common pests such as aphids and spider mites, as well as diseases like soybean rust. Vigilance is crucial in Hawaii’s humid climate.
- Implement organic pest control methods and rotate crops to reduce disease and pest pressure.
Harvesting
- Harvest soybeans when the pods turn yellow and the beans inside are firm. Regular harvesting can help maintain productivity.
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 🙂
