What you need to know to Plant & Grow
Establishing a native septic bed cover requires patience, as these mixtures typically take three to four years to become fully established and self-sustaining.
-
Best Sowing Time: Late fall (Oct. 15 – Nov. 15) is ideal. Winter weather naturally stratifies the seeds, breaking their dormancy for spring. Spring sowing in April is possible, but some varieties may stay dormant until the following year.
-
Site Preparation: Clear existing weeds manually or with an organic herbicide. Loosen the soil to a 2.5 cm depth; native seeds establish far better in loose soil than in compacted topsoil.
-
Sowing: Broadcast seed evenly. To ensure even distribution of the smaller seeds, mix the blend with dry sand before sowing. Mother Nature (rain and snow) will work the seeds into the soil bed.
-
Early Maintenance: During the first two seasons, mow the area to a height of 20 cm a few times. This prevents aggressive weeds from overshadowing the slow-growing native seedlings while they establish their root systems.
