Different vegetables have different germination requirements. It’s important to know the germination requirements of the seeds you are planting to ensure success. Viable seeds are alive; they contain an embryo, stored food and are surrounded by a seed coat. A seed will germinate or begin to grow when soil moisture, temperature, and oxygen as well…

Vegetable Seed Germination Temperatures
Vegetable seed germination is greatly dependent upon soil temperature. Other near equal factors include seed vitality (the age of the seed), soil moisture, soil air, and soil conditions and workability. This chart shows the range of soil temperatures needed for seed germination. The chart also shows the number of days to germination at optimum temperatures….
Seed Germination Requirements
Most seeds need only moisture and warmth in order to sprout. But some seeds may have additional requirements. Check seed packets or planting guides for germination and cultural tips for the seeds you are planting. Light. Some seeds such as beans need darkness in order to germinate; other seeds such a lettuce need light. Seeds…

Seeds and seedlings, as well, require optimal temperatures, even watering, open air circulation, and bright light to thrive. When vegetable seeds fail to sprout or when seedlings wither and die what could the problem be? Often the answer is simple. Seeds Fail to…
Pre-Sprouting Vegetable Seeds
Pre-sprouting vegetable seed will help you avoid over-sowing in the greenhouse or garden. Pre-sprouting also answers the question: Is this seed still viable? To pre-sprout seeds place the seeds on a damp paper towel. Make sure that the seeds are well spaced and not touching one another. Fold the towel in half. Alternatively, place the…
Seed Failure Troubleshooting
When a seed fails to sprout there is usually a simple and easily correctable reason. Here are the most common reasons seeds do not sprout along with troubleshooting solutions. Soil is too dry. Small seeds sown very near the surface often fail from lack of moisture. They may have enough moisture to germinate, but then…
