Soaking seeds before planting them mimics the favorable growing conditions after a spring rain. Water is what wakes up many types of seeds and tells them it’s the right time to sprout. So do you ...
Scarification is often done mechanically, thermally, and chemically. The seeds of many plant species are often impervious to water and gases, thus preventing or delaying germination. Any process designed to make the testa (seed coat) more permeable to water and gases is known as scarification.
Most seeds are started indoors about 6 to 8 weeks before the last frost date of spring. But planting schedules will vary depending on your growing zone, your area's frost date, and the types of ...

Warm stratification requires temperatures of 15–20 °C (59–68 °F). In many instances, warm stratification followed by cold stratification requirements can also be met by planting the seeds in summer in a mulched bed for expected germination the following spring. Some seeds may not germinate until the second spring. [citation needed]
In the late spring and again in late fall. The early mowing helps clear away competitors that might impede growth. The late mowing chops up the dry seed pods resulting in some scarification and resulting in better germination. USDA hardiness zones 5–8 are recommended for outside cultivation. The waxy seed coat needs to be scarified prior to ...
