Why You Need a Good Weed and Feed for Southern Lawns
Anyone just getting into gardening, or any sort of green-thumb activity, may not understand how vital fertilizer is for a lawn.
The fertilizer will be designed to add nutrients to your garden so your lawn can achieve optimal growth. You have three key nutrients: nitrogen, phosphorus and potassium.
Nitrogen helps grass and plants grow, making them lush and green. Phosphorus helps with root growth, and potassium, or potash, helps with roots and helps protect plants from drought and disease.
Fertilizers can also help with oxygen, carbon, calcium, magnesium, boron, cobalt, iron, deficiencies and many more.
You find these are required in far smaller quantities, and only certain ones may need supplementing depending on the soil conditions.
Your first step in choosing any weed and feed fertilizer is finding out what your yard requires. You can get kits to carry out your soil test.
After this, you need to think about your weed issues. The types of weeds will dictate the type of weed killer you require, as will the time of year.
A weed and feed product tends to contain a pre-emergent weed killer that stops weeds from germinating. Later weed control will be from sprays, where you tend to spray each weed individually.

Best Weed and Feed for Southern Lawns Buying guide
When you are after the best lawn feed and weed, you need to be aware it isn’t purely fertilizer.
Weed and feed like the ones above (or Spectracide Weed feed and Preen One Lawncare weed and feed) are available as granules, though you may find some liquid forms of this type of product.
Fertilizers only feed lawn nutrients and are for weed control. Ideally, you should use fertilizer and herbicide to grow a lush lawn. However, should you be overpowered with weeds, then the use of a weed and feed solution makes sense. (Learn How to Get Rid of Chickweed)
Don’t apply any of these lawn care products if your lawn doesn’t need them. If there are only a few weeds, you are better to use a post-emergent herbicide weed killer.
However, if your lawn is unhealthy, and you have weeds, a weed and feed treatment could be suitable.
Dry and wet weed and feed contain both herbicides and fertilizers. Multi-tasking, kill weeds while providing essential nutrients, so you need to consider a few things.
Nitrogen content: Grass needs nitrogen to be lush and green. However, too much can harm it. Along with nitrogen, you need small amounts of potassium and phosphorus, that work to weaken the concentration of nitrogen.
Weeds it kills: Many weed and feed products are engineered to kill several types of weeds, although you can find some that won’t.
Grass compatibility: In the same way as weeds, not all weed and feeds suit certain grass types.
While checking everything for these weed and feed reviews, there were lots to consider aside from price.
