How Warm Must it Be to Plant Lawn Grass Seed? Warm-season grasses, like St. Augustine (Stenotaphrum secundatum), which grows in U.S. Department of Agriculture plant hardiness zones 8 through 10, rely on daytime temperatures hovering around 80 degrees Fahrenheit for successful germination.But air temperature may not be the best indicator of soil temperature.rass seed not in good contact with the soil cannot warm up correctly for successful germination. Seeds rely on warmth and soil moisture to swell and sprout. If your seeds remain at their ideal temperature range and are planted no more than 1/4 inch deep, you should see germination after three weeks.

The Best Temperature to Germinate Chillies In the past i’ve experienced slow germination times of up to 1 month or more. One of the key factors that affects germination speed and rates is temperature. It is generally accepted that the optimum temperature to germinate chillies is between 23-30 degrees Celsius (73-86 degrees Fahrenheit).If you can maintain your seed’s compost within this range then you should experience good germination rates.t is surprising how soil temperatures can vary, even a high end thermostatically controlled propagator. As the ambient temperature around the propagator cools (usually over night) soil temperatures can easily drop off 5-10 degrees or more.

The Best Time to Plant Grass Seed Several distinct advantages make fall the best time to plant cool-season grass seed. In early autumn, the soil is still warm from months of summer sun. This combination of warm soil, moderate day temperatures and cool evenings encourages fast germination and establishment of newly sown cool-season grass seed. Cool-season grass seed germinates best when soil temperatures are between 50 and 65 degrees Fahrenheit. This roughly corresponds to daytime air temperatures in the 60 F to 75 F range. An inexpensive soil thermometer, available at most garden stores, can help eliminate the guesswork.

Grass Seed Germination Time Now, most germination failure (especially with warm season grass) is because the grass seed was planted too early. Grass seeds have an outer shell (the hull) that prevents germination until conditions are right. Proper soil temperature is a big factor in the success you’ll have. For cool season grass, the ideal soil temperature is a minimum of 45-55 degrees (F). For warm season grass, the ideal soil temperature is a minimum of 55-65 degrees (F).
