Different species of grass respond better to different fertilizer formulations. If you don’t know what kind of grass you have growing in your yard, then take a sample along to your nursery when you go for the soil test. An experienced gardener will be able to tell you what kind of grass it is with a simple look at your sample.

Tips for Feeding Your Lawn
No, weed and feed formulas in this review are designed explicitly for grass. Using these nutrients on your plants may result in the burning of the foliage and damage to the root systems of the shrubs and trees.
Some fertilizers feature slow-release formulas, and you don’t have to fertilize as often to achieve good results. However, most fertilizers require you to treat the lawn at least every 8-weeks from the start of spring.
This long-lasting formula keeps your lawn looking tip-top for up to 6-months. It feeds the grass while killing off pests.

If your lawn is relatively trouble-free then a standard lawn feed is your best solution. But if your lawn is plagued with moss and weeds then you're going to need a feed that can treat these problems.
Best lawn feeds
Moss thrives in the shade and you'll often find it growing under trees. Consider cutting back some of the lower branches, thinning the coverage and letting more light through. If it's compacted, pushing a garden fork into your turf every 15cm or so will get some much needed air back into your grass. This will also help prevent moss. You should regularly move heavy items around the garden, so the grass underneath can get a breather. And if you've been using moss killer then remember to rake away the dead moss. You'll need to seed the bare patches with more grass otherwise the moss could simply re-grow. Help the new grass grow quicker by adding some top dressing to the bare patches.

Whichever product you are using, always carefully read the label before use and apply according to the instructions.
The reason some lawn feeds are better than others, is because they can release nitrogen and feed over several weeks rather than in one rush soon after application.
To summarise, steps to take for lawn feeding include:
For spring feeding, use a product containing feed, weed killers and moss control. This will quickly help the grass to start growing again and control any weeds that are present, plus kill off the moss that might have invaded the lawn over the winter.
Spring and summer lawn feeding
During these conditions stop feeding your lawn, wait until it has rained to let the water soak in for a few days, then start feeding again. Feed throughout the summer at 6-8 week intervals, weather permitting.
The best lawn feed (or fertiliser) to use is one that provides both protection from weeds while systematically feeding your lawn. Ideally, lawn feed should be applied between April and September with Miracle-Gro EverGreen Complete 4 in 1 providing year-round feed when applied no more than twice a year.
Additionally, some have moss control added for any moss present. It’s important to feed with a specific autumn lawn food such as Miracle-Gro EverGreen Autumn Lawn Care, to get the grass ready for the colder, wetter weather in winter and get the lawn ready for spring. Autumn lawn feeds will be low in nitrogen, as we don’t want to encourage any top growth, which can be soft and easily burnt by frost.
Which lawn feed should I use?
Once the weeds and moss are under control later in the spring, move over to just a lawn feed to keep the grass looking thick and green. Liquid lawn feeds via a hose end feeder are ideal for using in late spring into summer as they water the lawn as well in dry periods.
Without food to develop side shoots and thickness, the lawn seed is also open to invasion by weed seeds and moss, that thrive in low nutrient conditions. On the other hand, a regular supply of supplementary food makes your lawn thick and green.
