Seed Germination Basics
Spring is usually the time for planting, and most often planting occurs from germinating the seeds. Today we are going to review some of the basics of seed germination process, so follow these tips to learn more!
Seed Germination Tips
Most plants are reproducing themselves with a tiny embryonic germ layer, which is hidden in the seed. The development of this replica takes place during germination process. The plants that need to go through this process are tomatoes, carrots, peppers, and as you know nuts are also seeds and much more.
Well, to start the germination process, you need to have the fresh seeds, because their capacity of development is decreasing with time. The soil should be aerated, and preferably some peat moss should also be included. The seeds require watering and heat. The germination process requires certain conditions which differ from plant to plant.
For instance, geranium seeds require total darkness to germinate, because the light inhibits their growth. On the contrary, petunia seeds love to germinate in light, but that doesn’t mean completely on the surface. The light loving seeds need to be slightly pushed into the ground to germinate, because the light exposure also draws away the water.
Now, some plants, such as morning glory and moonflower, require scarification in order to germinate. Scarification is the process of altering the seed’s shell in order to allow the nutrients inside, to the developing seed embryo. In nature this is done in winter, when the shell of seeds freezes and cracks.
Another type of seed germination is called stratification, and it means that the dormancy of the seed should be shaken out by means of shock strategy. The seeds, that need this procedure, should be exposed to winter conditions, so their dormancy would be shaken out. The stratification is required by seeds of trees and bushes, namely the dogwood, magnolia, and buckeye, which can be sown outside in autumn or chilled in a refrigerator for sowing the following spring.
