The temperature needs of seed differ during and after they germinate. The soil needs to be warmer during germination and then cooler as they get larger. The recommended temperature for seeds starting indoors is 75-90 degrees Fahrenheit. Once germinated, most seeds are fine in 60-70 degrees Fahrenheit.
Different seeds have different requirements in the amount of light they require for germination. Some seeds must have a lot of light and others should have no light. Like the Times For Starting Seeds, this should be listed on the package.
Once germination has occurred, the seedling requires light in order to undergo its core life processes. It doesn’t matter whether the light is natural or artificial.
Most seedlings require 12-18 hours of sunlight per day.
When you’re ready to start the seeds, just add water. The moisture softens the coating of the seed and allows the internal food source to start feeding the seedling.
A very important point to keep note of is that the seed medium must stay moist at all times but not soggy. If it gets too soggy, the roots and seed will rot and/or grow mold. However, if it gets too dry, the roots will dry out and die.
Most garden centers sell Seed Raising Mix, which is usually a mix of compost, soil and sand. This is much easier to grow seeds in as it holds moisture much better.
When growing plants from seed indoors, you can plant them nearly any time of the year. However, when setting out to plant them outdoors, you need a strategy.
You should find out the date for the last frost in your area and then the number of weeks prior to that date to plant the seed. This is almost always printed on the seed package.
From here, you plant the seed and prepare for growth. A general rule for planting seeds is about six to eight weeks before the last frost date.
We’ve put together a small collection of information about the basics of starting with seeds.
While starting a plant from seed may seem more difficult, it has many benefits. You’ll be saving money as seeds are much cheaper than plants, you’re able to start the growing season earlier and you can extend your options on varieties available.
There is something very therapeutic about starting plants from seed too! You are able to watch a small seed turn into a healthy living plant.
