Will the seeds require full and direct light?  Or will they come up in shady conditions

We selected a variety of seeds for this mix to ensure they would germinate and grow in any conditions found on the mountain.  Therefore, you may see certain plants come up in the shade, while others will germinate in direct sunlight.  This also holds true for moist vs. dry sites and North-facing slopes vs. South-facing slopes.

Do we need to worry about birds eating the seeds?

Typically, birds will eat seed that is just distributed on the soil surface, but they will not eat more than about 10% of the seed.  If you are concerned about the loss of seed to bird consumption, you may rake over the seed once you’ve distributed it onto the soil.  This will make it less likely for birds to have easy access to the seed. Back to FAQ Top

What species are included in the mix?

Species included in the mix are shown in the brochure. The list is also on the SEED MIX page.  Photos are provided for your reference of each species.  Please note that you may not see all of the species germinate and sprout in every area of seeding because germination depends on the specific microsite.Back to FAQ Top

What germination rates should we expect?

The germination rates will be dependent on a number of factors.  If you choose to spread your seed via broadcast seeding (toss and spread seed without scratching the soil surface) your expected germination rate will be approximately 40-50%.  If you scratch the soil surface then distribute the seed, your expected germination rate will increase to 80-90%.  There will be some seed mortality due to a number of causes (animals, non-viability, and others).Back to FAQ Top

What about mulch?

Mulching over the seeded area is not necessary.  In the wild (or in a natural setting), these plants would typically just drop their seeds when they are mature and future plants would develop from those seeds.  We are merely replicating that process.  If you scratch the soil surface, you are providing a better chance for those seeds to come into direct contact with surface soil, which will improve their chances.  If you would like to rake over the seeded area again once you’ve spread the seed (mixing seed and soil a bit more), this is perfectly acceptable – although you need to take care to not bury the seeds.  The seeds should be fairly close to the surface of the soil to respond to sunlight and available moisture. Back to FAQ Top

Should seeds be spread all over our yard?

We recommend planting seeds in small patches across your entire property, to better replicate the natural growth of plants.  Plants typically occur in patches because their seed dispersal is limited to where the seeds fall.Back to FAQ Top

Should we be concerned about wood chips on the ground?

If your site has wood chips spread evenly across the surface, use your rake to clear away some of the heavy mulch (wood chips and other woody debris like twigs and small branches), then plant your seeds as described on the brochure.  You may rake over the surface again (to mix seeds into soil), but do not cover the seeded area again with wood chips.  You can decrease erosion potential by leaving mulched areas down slope of the treated site (within one rake’s distance of seeded area).Back to FAQ Top
