High-maintenance lawns benefit from spring fertilizing. You need to decide if you prefer to use an natural organic or synthetic fertilizer. Both are good products. Synthetic fertilizers are often mistakenly called chemical fertilizers. No matter what type you use, all of them are chemical.
Most synthetic fertilizers release their nitrogen quickly after they are applied.
Natural organic products fertilize as they are broken down over a period of weeks by soil micro-organisms. Straight Fertilizer or Combination Products Fertilizers are often combined with herbicides so you can apply both to your lawn at one time. If you need both and the timing is right for both, combination products are a good idea. If your lawn only has a weed problem in a limited area, we advise using a straight fertilizer when needed and spot treating separately with the appropriate herbicide. This not only limits the amount of herbicide you need to use and puts it exactly where you need it, the spot treatments limit the risk of damaging desirable plants.
