5 Gardening Tips to Improve Seed Germination

  1. Pre-Soak Your Seeds Before Planting. Plants lie dormant until the seeds detect enough regular moisture to be able to grow.
  2. Begin by Starting Your Seeds Indoors.
  3. Monitor Your Seed’s Environment.
  4. Keep Them Well-Watered.
  5. Change Seed Sources.

What are the main environmental factors that affect germination?

Environmental factors such as temperature, light, pH, and soil moisture are known to affect seed germination (Chachalis and Reddy 2000; Taylorson 1987). Burial depth of seed also affects seed germination and seedling emer- gence. Weed seedlings may emerge from the soil surface to 15 cm deep (Bello et al.

What are the essential conditions 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.
