You can apply a granular fertilizer on top of the mulch. Water in. It will make its way to the plant roots. Or you can apply a liquid fertilizer on the foliage and the mulch.
The reason that you want to apply a fertiliser beforehand is because mulch removes a bit of nitrogen out of the soil when it fresh and starting to break down. However, after this first stage it then begins to add nitrogen into the soil, so it is very beneficial to your garden in the long run.
Prior to planting, fertilizer is applied to the soil surface in a band. After application, the fertilizer can be incorporated into the soil. Under certain conditions, nitrogen availability is increased when applied in a surface band as opposed to broadcasted.
The general rule of thumb is to spread mulch about two to four inches thick over the soil surface. When mulch is too thick, it can be counterproductive and prevent water from reaching the soil. On the flip side, too thin a layer of mulch may not adequately stop weed growth or prevent evaporation as intended.
You can usually apply most non-liquid granular fertilizers to wet grass, but not saturated ground. If there are ponds or heavy rain, it's best to wait until the ground processes the water before applying any type of fertilizer. If there's light rain, it's okay to spread dry granular fertilizer.
Late afternoon or early evening (when there's still light, of course) is the best time of day to apply lawn fertilizer. Applying it in the heat of a scorching afternoon can cause the sun's rays to burn your grass—and when your goal is “lush and green,” burned grass blades simply won't cut it.
If your lawn gets liquid fertilizer, wait until it dries before watering, about 2-4 hours. If it's granular fertilizer, water right away.

The ideal soil is new soil or topsoil. Light, sandy soil is the best type of soil to put on top of mulch because it allows water to penetrate fast to reach the plant roots or seeds. If you've clay soil, you can improve its texture by mixing it with sandy soil or adding organic matter.
Make sure the soil does not need gentle raking to loosen the soil. Then, add 2 to 3 inches of composted manure to the soil surface. Put the mulch back over the top. This is your manure sandwich.
Fertilizer is applied in bands near where developing roots will easily reach it; either to the side and below the seed rows, slightly below the seeds, or in between rows. A common practice is to band fertilizer 2 inches to the side and 2 inches deeper than the seeds or plants.
Lawn fertilising tips
Allow at least two days after mowing before fertilising. Wait about a week after feeding before you mow - and leave the catcher off the first time (the fertiliser could all end up in it if it's left on!)
No matter which kind of grass, you want to fertilize your lawn while it's actively growing. For cool-season grasses, that means in spring and/or fall. Warm-season grasses respond best when fertilized in late spring and/or early summer.
Give your lawn a natural boost by leaving those clippings on your lawn. They will eventually decompose and release extra organic nutrients and water back into your soil. What's not to love about that additional nutrient boost?
Because mulch offers far more than mere aesthetic benefits, we typically recommend mulching at least once a year.
Knowing how much mulch to use can be tricky. A 1-inch to 2-inch layer of fine mulch should be sufficient, while a coarser material should be 3 to 4 inches deep. Too much of either type can suffocate your plants. In areas where you simply want to keep anything from growing, you can lay it on as thick as you like.
“The best period to mulch is from late spring through to late summer when the grass is actively growing." While May is the ideal month for mulching fast-growing grass, the exact time you should do it to your own lawn will depend on the height of the green blades growing in your garden.
You should spread your mulch to be two to four inches thick. If your mulch is too thin, then weeds can push through. If your mulch is too thick, it prevents water from reaching the soil. Water after mulching — This is an optional step, but a final watering can help settle the mulch into place.
This simple solution is truly the best way to keep weeds from growing in mulch in the first place. To use landscape fabric, simply cut the fabric to the size of the planted trees, bushes, or shrubs before you start mulching. Then, place the fabric and spread mulch over until it's completely covered.
Focus on getting the bulk of the area. The next step is to decide how deep you would like the mulch to be. We recommend that you spread 1-2 inches of mulch per year.
It only takes between two to four weeks for quick-release lawn fertilizer to be absorbed completely. What is this? Slow-release fertilizers take much longer to break down, so it takes more time for all the nutrients to be absorbed by the soil and grass plants.
'You really need to avoid fertilizing your lawn prior to or after heavy rainfall. With so much water in your lawn, it can be nearly impossible for it to absorb the nutrients from your fertilizer. ' As a result, you need to be absolutely sure that the rain will be mild and that the wind will not pick up too much.
