I have a small yard, about 450 square feet, that I have seeded with Penncross Creeping Bentgrass. I used seed. This is the second year and I overseeded this year because I had a few spots I damaged with liquid fertilizer that was too strong (hot).
I have new grass growing in the ares of need and some in the among the existing grass. I've used guide from Penncross on Seedland and it works great for general information. I am struggling to figure out when I should mow the lawn. For new lawn I've found several links that say 30 days is when you can expect to mow. I'm concerned if I wait too long that the existing grass will grow tall and choke out the new seedlings. So my question is, when can I start to mow my overseeded lawn that is overseeded with Penncross Creeping Bentgrass?
I use a manual reel mower and I usually mow at a height of 3/4". After 14 days I have seed that has germinated and I have some existing grass that is over 3" tall. I feel like the tall grass needs to be tamed so the Penncross can thrive and fully take over. Then maybe I can start to cut this stuff down near 3/16" and practice my putting :).
