Do seeds need sunlight to start germinating?
While seeds can germinate in a glass of water in which the Sunlight is able to reach the seed, Sunlight isn’t required. If anything, sunlight might hurt a seeds ability to germinate by making the seed’s environment too warm. In part, this is because seeds need lots of water to germinate. Sunlight can dry up any water.
Does temperature effect seed germination?
Temperature affects the percentage of seeds that germinate and the rate of germination. Seeds kept at higher temperatures are more likely to deteriorate and not germinate. Once seeds start to germinate, higher temperatures stimulate faster germination up to an optimal temperature, after which the speed of germination declines.
What are the conditions needed for seeds to germinate?
Conditions Required for Bean Germination. Oxygen: For the proper growth of beans, oxygen plays a vital role. The germinating seed requires oxygen for metabolism. It is used as a part of aerobic respiration until the seed manages to grow leaves. It can be found in the soil particles' pores.

At what temperature do seeds not germinate?
Many seeds will fail to germinate above around 90-95 degrees F. If they have experienced temperatures approaching those inside your home, or in the garden, that may be the reason for the poor or non-existent germination.
What helps seeds germinate faster?
One easy way to make seeds germinate faster is to presoak them for 24 hours in a shallow container filled with hot tap water. Water will penetrate the seed coat and cause the embryos inside to plump up. Don't soak them for longer than 24 hours because they could rot. Plant the seeds immediately in moist soil.
Do seeds need light or dark to germinate?
Most seeds germinate best under dark conditions and might even be inhibited by light (e.g., Phacelia and Allium spp.). However, some species (e.g., Begonia, Primula, Coleus) need light to germinate (Miles and Brown 2007). Don't confuse seed light requirements with what seedlings need. All seedlings require sunlight.
What is the perfect condition for germination?
All seeds need water, oxygen, and proper temperature in order to germinate. Some seeds require proper light also. Some germinate better in full light while others require darkness to germinate. When a seed is exposed to the proper conditions, water and oxygen are taken in through the seed coat.

Timing Is Important
To grow strong grass as quickly as possible, you’ll need to plant the seeds in optimal growing conditions. Grass grows best in different climates depending on the type of grass that you use.
Best Temperature To Plant Cool-Season Grasses
Cool-season grasses are best planted in fall, as the start of fall brings soil that is still warm from summer. The soil is warm, while medium day temperatures and cooler nights provide optimum conditions for growth.
Best Temperature To Plant Warm Season Grass
Late spring and early summer bring rain and warm soil with it. This is a good time to plant warm-season grasses, as the soil is moist and warm enough for effective germination. These grass seeds do well in air that’s 80°F and warm soil that’s roughly 65°F to 70°F.
Things To Look Out For When Planting Grass Seed
If your timing is right, your grass seeds should settle and sprout well in optimum conditions. Well-cared-for grass can look different depending on the type of grass you use, where you live, and the weather conditions of the growing year.
