Warm-season grasses germinate best when soil temperatures are consistently in the 65°F to 70°F range. This generally corresponds to daytime air temperatures near 80°F or more. Planting in late spring and early summer gives warm-season grasses the advantage of warm soil and early seasonal rains, which help keep soil moisture available during germination and establishment.
As a general rule, plant cool-season grass seed at least 45 days before the estimated date of your first fall frost, before soil and air temperatures drop to less favorable levels. Your grasses will enjoy a full fall season, plus a second cool growing season come spring. Your local county extension agent can help with advice on average frost dates and optimal timing for seeding lawns in your area.
WHY FALL IS BEST FOR COOL-SEASON GRASSES
As a general rule, warm-season grasses planted at least 90 days before the first fall frost have time to establish well before winter. These summer-loving grasses go dormant once temperatures drop near 55°F, so late-planted seedlings can’t prepare for what’s ahead. With proper timing, warm-season grass seed gets a natural boost from summer’s warmth and a full season of active growth and development before cooling temperatures bring on winter dormancy.
Grass grows fastest and strongest when your planting season aligns with the seeds’ natural periods of active growth. Just as with other kinds of plants in your landscape, lawn grasses vary in their growth cycles and regional climate preferences.

Next, firm the soil by walking over it, then repeat the process. If you are working with sandy soil, you’ll want to add lawn soil to help hold moisture better as well.
You can also choose from a range of more specialist mixes, like Miracle-Gro EverGreen Luxury Lawn Seed, which uses a sports-grade seed, or Miracle-Gro EverGreen Shady Lawn Seed, that’s designed to thrive in more shady locations.
A couple of days before you sow your grass seed it’s also a good idea to rake in a small amount of general lawn fertiliser such as Miracle-Gro Growmore Garden Plant Food at 35gm/sqm a few days before sowing seed. This will help prepare the soil and give your grass the best chance of growing.
A fantastic lawn isn’t as difficult as you think and doesn’t need to be costly either. Armed with the right information, you can figure out when the best time to sow grass seed is, how to choose it, sow it, and look after it. Get to grips with the basics with our tips and tricks.
When the new grass is about 7.5cm high cut off the top ⅓ with a sharp mower blade. Cutting the grass will encourage it to send out more shoots to thicken up the sward.
Timing is everything when it comes to lawn care. If you apply weed and feed too early, you risk the chance that you will miss attacking the weeds that have not yet started to grow, and they will survive the application. But, on the other hand, if you wait too long, your grass won’t get the nutrition it needs to grow well. The ideal time to apply weed and feed is in the early spring, just about the same time that you notice your lawn needs the first trim of the season.
The term “weed and feed” is a general term for a number of products. Most of these products combine post-emergent broadleaf herbicides to kill weeds such as dandelions and clovers with fertilizers to give your lawn a quick dose of the nutrients it needs after a tough winter. Weed and feed products are produced by most major lawn care manufacturers and come as a ready-to-go liquid or in a dry granular form.
What is Weed and Feed?
Besides choosing the best time of the year to apply weed and feed to your lawn, you need to keep an eye on the weekly weather forecast as well. Avoid treating your lawn with weed and feed when the weatherman predicts rain is on the way. A spring storm shortly after an application will dilute the herbicide too much to be effective. If a surprise downpour does happen to catch you off-guard, you should not reapply the treatment because you will then risk overfeeding your lawn.
As soon as the winter months are over, legions of homeowners rush outside to check how their lawns survived the cold. Most of them will head inside with disappointment. If you are among the majority of Americans with sad-looking lawns this spring, you may already be planning to wake it up with a quick application of weed and feed over the weekend. But before taking the trip to your local garden store to pick up a few bottles, there are several good reasons why using weed and feed now may not be the best idea for the health of your grass. It is important to know when to apply weed and feed.
Even when you choose the perfect time and weather for a weed and feed treatment, things can still go wrong. You can increase the chance of a successful application by following these tips:
