The rainy spring is starting to come to an end, Memorial Day weekend has come and gone, and hopefully by now you’ve completed your May lawn care schedule. If so, your lawns should be a deep dark green and growing like crazy. Now as warmer temperatures are rapidly approaching, it’s time to think about how to care for our lawns in June.
This how-to lawn care calendar is a month-to-month guide for cool season grasses – particularly Massachusetts and Zone 6 that have grasses like Turf Type Tall Fescue and Perennial Ryegrass. Following LawnPhix’s monthly lawn care guide will help you kickstart your turf health, vigor, and color this spring, and set your lawn up for success this growing season.
June Lawn Care Maintenance Schedule
- The first day of summer is June 21, 2019
Jumping right into it, the two most important things you can do this month is to begin a preventative strategy against grubs (or sod webworms) and fungus (like brown patch).
If you or your neighbors have been impacted by grubs in the past, then you especially absolutely, positively need a preventative strategy. Even if you haven’t, it’ is highly suggested! These little buggers can wreak havoc on your lawns. Not to bore you with the entire life cycle of the June or Japanese beetles, but evidence of the young larvae eating the roots of your grass will be: brown patches of dead grass that grow over time (not to be confused with fungus). This brown grass can be easily peeled away like a carpet. There you will see the grub on the outside of the brown patches, working their way to the healthy, greener grass roots.
A product like Merit contains imidacloprid as its active ingredient, and is most effective as a preventative. But it’s very important to do this sooner than later. Waiting too long after the beatles have laid their eggs will require a more reactionary and curative approach. Dylox, which active ingredient is trichlorfon, can cure active grubs if used correctly. read the label and apply the recommended rates and water-in immediately. This will kill the grubs so you can stop the bleeding and think of a recovery/reseeding program (coming in the fall).
Bayer Advanced also sell smaller bags that, again, are more readily available at your local hardware and big box stores. Scott’s GrubEX is another option, but also better suited as an earlier preventative.
Whichever product you choose, just make sure you’re treating the right insect (sod webworms, grubs) and at the right stage (prevention vs. killing).
As previously mentioned, there was quite a bit of rain in May. Coupled with some warm and humid days is a perfect mix for fungus to appear. As someone who has primarily TTTF, brown patch is something I need to prepare for every summer. Azoxystrobin – and active ingredient in both Heritage G and Scott’s DiseaseEX – is a product I put down in early April, and will follow up with another preventative application in four weeks of the first application.
Generally fungicides have a 28 preventative/curative timeline – meaning it’ll be time to re-apply in 28 days from first does if fungus is still present.
It’s a good idea to alternate applications of Azoxystrobin and Propiconazole and/or Myclobutanil (Eagle). This is one of the best fungicide guides and can give you a great head-start on what to use, when, and for the most cost-effective way.
As we mentioned back in May – mowing your lawn is the single-most important lawn care task that you can control to build a thick, healthy turf. Try to keep in the habit of mowing twice per week and mulch your clippings whenever possible. Frequent mowings will allow you to keep up with the fast-growing turf, encourage more growth, and allow you take take off no more than 1/3 of the grass blades at a time.
For example, if you’re away on vacation and skip a week of cutting the grass and come back to eight inch blades (8″) you’re going to want to jack your mower all the way to the highest setting and And it’s unlikely that 2″ grass clippings will actually mulch, so it’s probably a good idea to use your bagger to pick up that grass. Leaving long blades of grass on your lawn is not going to do any good – so bag ’em.
Weed Prevention & Weed Killers
If you’re following the split application approach to pre-emergents, then you should have already put down your second and final application as soil temps have approached 65-70 degrees. Be sure to follow the instructions on the label, and make sure you stay within the bag rate’s annual limitations. Example, I put down prodiamine at 3lbs./1,000 in early April when my soil temps were are around 50 degrees. I just applied my second application – this time using Lesco 19-0-7 with Dimension – over memorial Day weekend. Soil temps were over 60 degrees, and the historical temperatures were steady at 65 degrees. This should get me through the summer safely, barring any more torrential downpours of rain.
These Dithiopyr and Dimension products have some post emergent herbicides that will kill crabgrass and dandelions up to the three-leaf stage, which is why I opted for this instead of a second dose of prodiamine.
No matter how on-point you are with pre-emergents, you’re still going to find weeds no matter what. If you still need to spot-spray, be sure to read your labels. Generally these products should not go down if the outside air temperatures exceed 80-85 degrees. Also, there’s a limit to how much and how frequently you can apply – generally at least two weeks in between applications (for blanket spraying). Also adjust your mowing schedule to accommodate the recommended applications times between mowing.
A product like Bayer All In One Weed Killer is a good choice for spot spraying, and something readily available in big box stores like Home Depot. However, if you want to try something different, the best herbicide I’ve ever used is SpeedZone – which is also available on Amazon Prime.

Continue using organic fertilizers, especially as temperatures begin to rise. With another Milorganite shortage, check out our post for some great Milorganite alternatives.
If for some reason you skipped May fertilization, add a full rate early this month – aiming for roughly 3/4 lbs. of nitrogen per 1,000 ft2
To calculate the amount of nitrogen per 1,000 ft2, be sure to be sure to use my free nitrogen calculator.

Aa always, it’s a great idea to incorporate both humic acids and other micronutrients such as L-Amino acids into your lawn care plans. These, unlike your standard fertilizers, are generally safe to apply during the hot summer months. I’ve been using Kelp4Less Extreme Blend and Organic Humic Acid recently and am very pleased with the results. Each of these powders are under $20/lb. (with coupon codes) and can be easily mixed for backpack sprayer applications.
