Attachment B Growing Grass in Ramsey Starting, then maintaining, attractive turf in Ramsey is a challenge due to the sandy nature of the soiL Even more challenging is trying to keep turf green while using less water. The following are recommendations for growing turf in Ramsey: Preparing the Soil To save water and help roots grow, apply a highly organic soil of at least four (4) inches over the sandy soiL Adding a two (2) inch layer of clay into the subsoil will greatly improve water retention. Spreading a "salt free" fertilizer on the soil will encourage strong root growth. Ifnecessary, add enough lime to raise the pH to a level of6.5-7.0. The next step is to till your soil mixture to a minimum depth of six (6) inches. You now have a good, rich seedbed that encourages the grass to send roots deep to capture the nutrients for growth. This also reduces water and fertilizer waste due to evaporation and harmful runoff. Planting Now you are ready for sod or seed. When purchasing sod, keep in mind that locally produced sod is usually grown in a peat field with plenty of water close by, which is not similar to our typical Ramsey conditions. Most sod varieties are 80-100% Kentucky bluegrass, which is nice to look at, but is high maintenance and performs poorly in sand and shade. It may surprise you to know that seeding will create a better yard. When done correctly, your lawn will experience increased longevity and durability compared to sod. The best times to seed are right after the snow melts until about May 25, and again from August 25 to September 25. Planting after September results in poor germination and not enough growth to establish itself as a perenniaL Use fresh seeds known to do well in Minnesota. The best grass seed is a blend of . bluegrass, perennial rye and fescues. Knowing what type of yard you want is beneficial before selecting your seed. Bluegrass and perennial rye are for show and fescue varieties are best for shade. Purchase seed from a reputable retailer who will explain each variety of seed in the mix and how it will be able to meet your needs. When planting on hills or the edge of walkout basements, a fast growing annual rye, planted with the perennial mix for a starter, will control erosion more effectively. Rye grass emits a harmless toxin that kills other broadleaf plants, creating less competition for survival of the new grass seedlings. There are many ways to plant and most will work, but the most common practices are slit seeding, broadcast and rolling and the popular hydro seeding. Mulching grass seed after planting improves germination of the seed. Rye straw is best for this as few weeds are found in this straw. After the straw blanket is applied, a slit disc will help hold straw in place, preventing erosion from wind or rain. The other benefit is that straw helps hold
