A few helpful observations about perennial rye

After two years and a lot of tests with rye I'd like to share a few observations I've made that go against conventional advice and may be helpful for you guys.

1. It can be mowed incredibly early. I've cut ryegrass with my tournament blade at 2mm from germination and it immediately started tillering and ended up looking incredible never mowed higher than .250. This was all during the heat of summer.

2. It's resilient from day one. I've viciously stomped down mole holes and high spots in my lawn and it just keep growing. I have a mostly sand lawn so it's hard, and when I say stomp, I mean all my weight viscously 6 or 7 stomps as hard as I could. Of course a couple seedlings probably died when they got torn apart but this was one or two days after germination and no noticeable damage just a full canopy recovery. I'm not saying there isn't merit to walking on newly germinated grass (you want every single seed you can to survive) but all the discussion about being careful not walking on the lawn is rubbish.

3. Higher height of cuts are the enemy. Rye maintained short will dry out much faster and be less susceptible to fungus. This, in my opinion, offsets the advantage you get from any vigor or strength the plant has at a higher HOC. This is regarding established ryegrass of course.

Hopes this helps at least one person. I'm in 6b.

Very nice information.

I've fixed some spots with PRG myself about 1 1/2 months ago and can definitely say that you don't need to wait a few weeks for the first cut. The sooner the better. I used sheers on my tiny spots after the first week and continued to cut it every other day. After about 12 DAG you could really tell that it started tillinger hard and responded very well to being cut.

Can also somewhat confirm the HOC and fungus correlation. My lawn got hit hard with fungus after getting sloppy with mowing due to rainy weather and increasing the HOC for summer. Went from mowing 3 times a week at roughly 1.3 to once or twice a week at 1.7.

Also loving my 1”, rye only, 1k sqft around the pool deck that I renovated last fall. It was beautiful and thick in the spring but grubs got me before I could put down pesticide. It’s still good but has some patches and some thinning. That said, a little seed and in two weeks the patches are filling. It’s amazing how quickly it grows.

I like everything about PRG other than it doesn't spread. I'd use it anytime other than I don't want to overseed. I end up going with KBG.
I know they've recently come out with some PRG that supposedly spreads but most of the stuff I've read said it doesn't really live up to the bill.

Good info though, thanks!

Another great thing about PRG is the extremely easy overseed. Just cut it short and throw the seed water it a couple of times a day in about 2 weeks you are good to go.

This is where I am also. If I were to redo my 1k sqft of Rye, I'd go with an agressive spreading KBG. This chunk of lawn is bordered by concrete for most of it so no risk of it taking over elsewhere. More importantly, this patch is next to the pool and the dogs swim. So they swim, hop out right next to it, and run across the lawn. The lawn sees a lot of water (hence I used 1/3 sand in my leveling last fall) and can get soft if I'm not careful. And then the dogs like to dig. All of that is a lot of abuse at times. A hard spreading dense turf KBG would probably be a better choice there. That said:

This is a huge saving grace. And Rye likes heat too so long as you have irrigation. My abused bit noted above took a hit from the dogs in a spot or two. Also had grubs hit it 2 weeks ago. I killed the grubs and did a quick overseed. After a week of seed being down I'm already getting decent growing. In a couple more weeks you'll barely be able to notice it aside from the young grass being lighter.
