Product Description:
D-thatch is a maintenance product. This means that with regular applications yearly in summer, you can keep thatch buildup in the lawn to a minimum. It can also be used to help speed up the recovery of dead spots in the lawn from disease or insects. The secret to N-Ext D-thatch™ is molasses. The sugars bring the microbes up to munch, and when the molasses runs out, they turn to the thatch as a secondary food source.

What is Thatch?
Thatch is the layer of dead organic materials lying between your healthy turfgrass and soil/root system. It usually consists of stems, stolons, rhizomes, and roots that haven’t decomposed. When your thatch layer is manageable at around 1/2" thick or less, it is a nice place for microbes to hang out, which also helps this area to retain moisture. This also helps keep the soil cooler on the hottest of days.

Is D-Thatch As Good as Mechanical D-thatching?
No, it's not. Using those machines to literally rip out thatch is much more aggressive and immediate than using D-thatch. D-thatch is more of a maintenance-type product. If your thatch is okay or just getting out of hand, you can apply D-thatch 3-4 times during the summer, and it will, over time, melt the thatch down.

LOVE MY SINK CADDY!
Color: Black
This caddy is such a game changer for my kitchen. It keeps everything neat and in one place AND no more clutter around the sink! I can fit my soap, sponges, and brushes easily, and it still looks nice on the counter. The drying base really works too! It absorbs water fast and doesn’t get gross like other trays I’ve had. It’s sturdy, doesn’t slip, and even looks kind of decorative. Definitely worth it!

Great Sink Caddy
Color: Black, Color: Black
Great size and you can configure it to accommodate a range of soaps and gadgets. The brush holder can be moved to the outside for more storage area in the main basket. The little divider adjust across the wires and it stays in place. The stone bottom absorbs drips quickly and I haven’t noticed any discoloration on it. It stays in place on the sink edge. Perfect for my organization needs and keeps the area neat vs tossing the brushes on the ledge leaving water marks on the counter. It was packaged well and the coating seems good! I bought a cheaper one and it came bent, with the coating popped off in several places. This one is worth paying a little bit more for the quality!

Wonderful, roomy caddy
Color: Black
I don't usually write reviews, but this is a great product to share. This sink caddy is everything they say it is. The bottom drying stone protects the counter surface from getting wet and sponges, etc. dry in a reasonable amt. of time. I love the basket for tall items like brushes- enough room for two- and the removable partition to use however one wants. I debated getting this longer one, but I am glad I did because it fits quite a bit. I even use the one side with the partition for a spray bottle. It also looks very nice and feels like a quality product. I wasn't sure if the black metal would go well with my beige countertop, but it looks great. I highly recommend it.

This organizer is awesome!
Color: Black
This sink organizer works great! It fits everything I need to fit and works well on my countertop. The diatomaceous earth stone underneath collects all of the water and there is no puddling underneath. I love the divider because I can keep my sponge separate from my bottle of dish soap and brushes… 10 out of 10 would definitely recommend this item!
