Site Preparation - Proper site preparation is important for germination of seed and healthy growth of seedlings. Best results will be obtained by planting on cleared ground. Remove existing vegetation to avoid competition from other plants by pulling, tilling under, spraying with a general herbicide, or a combination of these methods. The success of these methods will depend on the size of the area, and the type and density of the vegetation. Loosen soil by scraping, tilling or scarifying. Tilling should be utilized only when soil is very compacted and further weed control measures can be taken. If soil is devoid of nutrients add PermaMatrix BSA or PermaMatrix BSP per Manufacturer’s recommendation. See page 66 for more information.
Custom Mixtures - In certain cases, a custom blend will be most suitable for your project. We can blend a custom native, turf, erosion control or wildflower mixture according to your specifications. Such mixtures may be based on application, height, climatic conditions, blooming times or other considerations. Seed size, aggressiveness and cost determine proportions of species. Our qualified staff will be glad to assist you in determining your needs.
Seed Application - Method of application depends on the size of the area and the terrain. On small areas, broadcast seeds evenly either by hand or by use of a drop or cyclone spreader. It is helpful to mix a carrier such as PermaMatrix BSP Foundation with the seed; this will greatly enhance the germination of the seed and help with even distribution of broadcast seed. Rake in lightly or drag the area lightly with a piece of chain link fence to mix the seed into the surface of the soil. For seeding large areas, i.e., over one acre, specially designed drills are most effective. Drill to a maximum of 1⁄4 inch and firm soil with a cultipacker; this maximizes seed/soil contact. Hydro-seeders are also effective, especially for steep slopes, rocky terrain and other areas where conditions make it impractical for driving equipment.
Hydro-seeding is the application of a slurry of seed and water to soil. We strongly recommend using PermaMatrix BSA (Biotic Soil Amendment) with all hydraulically applied seeding projects. The purpose of PermaMatrix is to provide the proper living components of soil so seeds can establish and sustain themselves. It should be used with an erosion control mulch that will hold seeds in place, help retain moisture and provide protection from erosion. Mulches are usually dyed green as a visual aid in even distribution. Rate of application for PermaMatrix BSA is 100 pounds per 1000 square feet. Application rates for most mulches are between 1500 and 2000 pounds per acre.
When using PermaMatrix BSA, mix seed with slurry and apply in single pass. When using only mulch, most authorities agree that germination is better when seed is applied first with 5-10% of the mulching fiber – the balance of the mulch being applied separately as a second step. This approach assures optimal seed/soil contact; otherwise, many seeds are wasted because they become suspended in the fiber.
Moisture - All seeds, including wildflowers, need ample moisture and soil temperatures to germinate and develop into healthy seedlings. Best results will be obtained by soaking the planted areas thoroughly and maintaining consistent moisture for 4-6 weeks – then gradually reducing waterings. In non-irrigated situations, plant in the spring or before periods of anticipated rain
in the fall. After seedlings are established, watering may be reduced depending on the climate and rainfall. In arid climates
or during drought conditions, up to 1⁄2 inch of supplemental water per week may be required to maintain an optimal display. If weeds are present, remember that they benefit from moisture as much as the wildflowers, and may dominate overwatered areas.
Fertilization - Many seed species benefit from some fertilization if the soil does not have adequate nutrients. Some species do fine in poor soils, while others require a more fertile environment. We recommend that a soil test be performed when soil quality is unknown. If the soil needs improvement, use a organic fertilizer such as PermaMatrix Grow BSPTM to enhance the macro nutrients in soil along with a suite of microbiologicals. In addition to adding nutrients, PermaMatrix Grow BSPTM includes organic materials that enhance soil texture and encourage beneficial microorganisms.
