What Customers Are Saying
The Smart Patch grass seed product had mixed results. While some customers reported successful grass growth, especially when applied densely and with proper soil preparation, many others experienced poor germination and no growth despite following instructions. The product did not consistently meet the claims of results in 5 days. Overall, the reviews suggest this is a hit-or-miss product, with a significant number of unsatisfied customers.

The all in one features mulch, fertilizer and seed. The change in color is good for letting you know when to water. But, the seed came up very thin so I needed to add more fresh seed.
Smart Patch
Smart patch is easy to use. It contains all one needs to patch spots in the lawn. All one needs to do is scratch the spots needing grass and sprinkle the prepped with Smart Patch and keep it watered.

Not as good as the other one
First time using Pennington brand. Germination was hit or miss. Will not buy this brand again. Scotts works better for me.
Worth it.
True to its word, grass growth in five days. A solid amount of patch for your money.
this is the worst lawn repair I have purchased nothing but weeds
Smart patch
Worked well to fill in patches of dead grass
Disappointed
We bought it a month before the Best Buy date and put it down according to the instructions. The seed must have been dead because it hasn’t sprouted at all.
