Product Description:
Prodiamine 65 WG is a professionally formulated pre-emergent that is mixed in water and sprayed out as a liquid. 

Most DIYers use this product in spring to stop crabgrass. Crabgrass is an annual grassy weed that germinates in spring, grows lime green and large during summer, then, towards the later fall, drops seeds. The following spring, the process starts all over again. This is why crabgrass is called an “annual” grassy weed. The good news is that it can be stopped very effectively using this product.

The best time to apply Prodiamine is in the spring or fall, as soil temperatures are between 55F to 70F. This will give you approximately 3 months of pre-emergence protection.

For more details, you can check out the FREE Pre-Emergent Guide. If you download our FREE app it will tell you exactly when your soil temps cross these milestones.
For cool and warm-season lawns, our recommendation is two applications in spring if the target is crabgrass.

Application Information:
DO NOT use Prodiamine if you are seeding or reseeding, as it will keep your seed from germinating.

This product should be applied via a pump sprayer or battery-powered hand can, NOT recommended to be applied via a hose-end sprayer. Always read the label and follow safety equipment recommendations.

We recommend weighing this product on a scale to be accurate, and grams will be the easiest. See the following table for the application rates we recommend. The product must be watered in within 48 hours; the sooner, the better with ½” of water from irrigation or rainfall.

Yeah, they shrink, a lot.
Size: X-Large, Color: Light Grey Heather, Pocket Description: Pocket
I knew they would shrink but I needed to know if so on permanent press cycle. Well they shrink a lot. I bought two and they were very comfortable and soft. I'm not returning since Amazon made it clear they will shrink. I'm the dummy.

A Good Value
Size: X-Large, Color: White, Pocket Description: No Pocket
I really like these shirts and have ordered a number of them so far. They're warm and comfortable and are of overall good quality. They will shrink substantially, and the arm length will be reduced. That being said I just order them a size larger than what I typically wear and know that the sleeves will be a bit short. Otherwise they're a quality shirt. The material is thick, but not overly so, and they don't seem to fade even after numerous washes. These shirts are durable, well-made, and are a good value.

Great Quality, 100% cotton, buy 1 size larger. I’m 100% happy!
Size: Large, Color: Black Charcoal Heather Stripe, Pocket Description: Pocket
I will be buying more of these. I knew they were 100% cotton so I bought a large when I normally wear a medium. After I washed it in warm water and dried it in the dryer, it fits perfectly. The cotton is of great quality not thin and flimsy. I expect to get plenty of wear out of this t-shirt. Also, it did not fade. I recommend buying one size larger.

Quality.
Color: Dark Indigo, Size: 34W x 29L
This pair Lee jeans, made on Mexico, fit perfect , zipper works great, 35.96 cost works for me. The pair of Smith jeans , zipper a struggle to make it work, zipper short in length, made in China, 51.62 does not work for me. You need to check quality of work from Chinese made products.

7 belt loops!
Color: Original Stone, Size: 36W x 32L
Finally Lee is making a pair of jeans with seven belt loops! And in loose fit! 50-year-old men with Dad bodies should not be wearing skinny jeans. Anyway great pair of jeans, size wise it's the same size as all the rest of my jeans. Should be good for summer work. The denim is a bit on the thinner side so I don't know how long they will last but they're good for now
