Perennial Ryegrass is like moderate temperature in the summer season as it is a cool climate lawn grass. You can expect to grow or maintain it in hot summer(over 90F) because of drought intolerant and ultra-sensitive to hot temperatures.
But in cool climates, summer is not that hot so you can have them on the lawn with less maintenance.
But still, perennial ryegrass can't just grow naturally in summer without efficient moisture, humidity, mowing, weed treatment, and dead patches recovery.
Here, I'll guide you in detail about the summer maintenance and care of Perennial ryegrass.
Perennial ryegrass summer care
Perennial Ryegrass doesn't expand with rhizomes, even if it's not invasive. Because of no rhizomes in perennial ryegrass, your lawn may have irregular gaps between grass seedlings. Although its a cool climate lawn grass like fescue but there are difference between Ryegrass and fescue grass.
This is one of the major problems in summer to keep its growth regularly even in the entire lawn.
Let's see how Perennial ryegrass behaves in the summer season.
How Perennial ryegrass behaves in summer?
- Brown spots
After recovering from dormancy, perennial ryegrass can't get 100% recovery because of its non-invasive nature. You have to work on each section manually to recover the spots.
In summer, the uneven treatment of the lawn may show you some brown spots or dead dried spots. Sometimes dollar spots become very common in perennial ryegrass lawns.
- Irregular growth
As I mentioned above, irregular growth is a result of the non-invasive nature of the grass. Rhizomes, which help to expand grass growth in an entire space, perennial ryegrass don't have these.
You can see sharp uneven gaps in lawn grass which looks ugly sometimes.
- High drought possibilities
In summer, if you ignore the soil moisture and overall humidity in the lawn, your ryegrass may feel some extra added pressure.
In case of more dry conditions, perennial ryegrass may start to get brown leaving edges and whole brown ultimately. In drought conditions, high chance that perennial ryegrass will die.
- Weeds
In summer, stubborn weeds may grow between the gap of the grass. These weeds are like clover, chickweeds, thistle, etc.
In summer, these weeds get ideal conditions to grow up and overshadow the perennial ryegrass easily.
Things to avoid in summer
Let's see which things you can avoid in summer so that you can keep ryegrass healthy with the least effort-
- Avoid overwatering in perennial ryegrass as much as possible. If someday you do overwater then make sure to not water for a few days till the soil doesn't need water.
- Don't mow your lawn in short durations. It can make your lawn grass in more trouble. Better to mow when it is required the most.
- Avoid any drought conditions that is happening due to high temperature, low humidity, and least soil moisture.

Guide to care Perennial ryegrass in summer
- Watering
Here, I'm sharing some valuable tips for DIY practicing so that you can keep your perennial ryegrass healthy in summer-
- Fertilization
Fertilization may help you while overseeding your lawn. Remember, fertilizing the lawn, again and again, may create more complications.
So use only natural or organic lawn feed for perennial ryegrass and apply it at once while overseeding the lawn.
- Overseeding
Overseeding is another very important step after weed removal, aeration, dethatching, and dead patches treatment.
Before overseeding, make sure you aerate the entire lawn and keep some moisture in the lawn. This is the time when you can fertilize or feed your entire lawn at once.
You need to be precise because uneven irregular gaps between grass look ugly and give you space for overseeding. While overseeding, you need to reseed some areas which are completely dead.
Overseeding is good after mowing the lawn to allow sunlight deeper into the soil for the grass seeds' germination.
- Aeration and dethatching
Perennial ryegrass lawn soil may get compacted after a complete annual cycle in spring. So you need to aerate and dethatch your lawn in spring or early summer in very less time.
First, dethatch your lawn if the soil is compacted. You can confirm soil compactness if it is not absorbing or too slowly absorbing the water. Also, you can pick a small slice of turf and check the roots of the grass to confirm their health. If roots are very short (about 1 inch) then there are multiple issues here; soil compacted and unwell grass health.
First, use a dethatcher and start with the worst-looking areas. If some sections are looking better then avoid dethatching but aerate once.
Remember, green sections don't need dethatching at that time but aeration is enough. You can practice both one by one in the worst dried or dead spots.
- Mowing
Mowing height is very crucial for perennial ryegrass. You should always keep the height within a certain range to keep it healthy. Most successful mowing height is considered between 2 to 3 inches above the ground. It means, after mowing your grass height should be between 2 to 3 inches.
- Weed control
Many times I've talked about how to remove weeds by hand-picking method, by using weed killers, and how to prevent their growth. Removal of weeds like dandelion, clover, chickweeds, thistle, and crabgrass is very important to have a healthy lawn.
You can apply weed-removing herbicides once your grass seeds develop and establish their growth.
- Diseases and pests controlling
Once you overseed your lawn, you can't do much about diseases and pest control. So make sure to target such problems earlier before overseeding.
Just keep things simple and focus on giving your lawn all the requirements. Better to prevent diseases instead of their treatment.
Although perennial ryegrass doesn't get such serious diseases in summer some pests may disturb you and your pets while walking on the lawn.
Ants, mites, and grubs may create some problems for you so make sure to treat them properly or call an expert to deal with them fundamentally.
