Nutrients

Nitrogen 3% is the mineral element used in the greatest quantity by turf. Nitrogen is a component of many of the biochemical constituents of plants, including chlorophyll, amino acids, proteins, and enzymes. The addition of Nitrogen fertilizer can encourage ideal conditions for a dense attractive lawn.

Phosphorus 18% The proper level of phosphorus in your grass is essential for root and early plant development. Its primary role is in the storage and transfer of energy. Without sufficient P, normal growth and development cannot occur. Phosphorus fertilizer effects on turf are usually more subtle and, while not as readily visible, are still very important.

Potassium 18% is involved in carbohydrate formation, photosynthesis, enzyme activation, and the formation of proteins. Potassium fertilizer plays a role in photosynthesis, and carbohydrate production is reduced when K is deficient. Potassium can enhance the plant’s endurance to stress if a deficiency is present.

Info 

For best results, water the lawn for 20 minutes within 24 hours of application. Water is essential for maintaining your lawn, and your lawn should receive 1-2 inches of water per week. Fertilizer will not treat a lawn that is suffering from disease, pests, weed infestations, or drought, and these conditions should be treated separately.

Not recommended to apply this product during drought, or drought-like conditions.

Super Comfortable and Soft
Color: White, Size: Throw Size - 50" X 60"
Feels luxurious and silky soft! It is not very thick but does keep me very warm. In fact I have to kick my legs out sometimes when I’m using it. It does shed A LOT! Will need to update after washing to see if that reduces the shedding. But it is beautiful and comfy. Is give it a 7 out of 10 for quality because of the shedding and the top and underneath pieces are only secured on the edges, which makes it move around and I have to grab the edges and shake to get its form back to normal. I would definitely purchase again. Especially if the shedding reduces it goes away after I run it through a wash cycle. I do NOT recommend drying in the dryer. It will mat I can almost guarantee that. Almost all blankets like these do if you dry them in a dryer with heat. Maybe no heat tumble might work, but NO heat.

Soft, Spooky, and Perfect for Cuddling
Color: Ouija-551, Size: 60"x80"
This Ouija Board Blanket is everything I hoped it would be and more! First off, it’s incredibly soft and comfortable—the kind of blanket you want to curl up in and never leave. The design is spooky and unique, which makes it a fun conversation piece, especially during movie nights or Halloween season. It's also huge, which means there’s plenty of room for me, my wife, and our pups to all cuddle up together. It is washable. We’ve already washed it a few times and it holds up great in the washing machine—no fading or fraying, which tells me it’s made from quality, durable material. It's also light weight. If you’re looking for something that’s both cozy and cool, this blanket is a perfect choice. Highly recommend!
