Why applications are missed

It’s easy to miss or forget about a Sunday fertilizer application, especially in the busiest time of the year—summer and back-to-school season. However, unforeseen weather and climate events can also get in the way of applications from time to time.

Here are the most common reasons we’ve learned why applications may have been missed:

All of these events are good reasons to not apply Sunday lawn nutrients. We fully support avoiding applications when they could be wasteful or worse—cause environmental issues for surrounding ecosystems.

Why hold onto lawn nutrients for next season?

Before you worry that you've wasted these nutrient applications, we’re here to assure you that there are ways you can use them this season or the following year! Leftover products aren’t just extra pouches to apply to your lawn either—they’re a bonus boost of nutrients to support lawn health and enhance grass growth. In almost every case, your lawn will benefit from these additional applications.

Things to consider before using older nutrients

  • How long you’ve had them. Most nutrients will be fine to apply for two years after receiving them. You’ll just want to prep liquid pouches properly before spraying by shaking with the cap tightly sealed!
  • Where nutrients were stored. Ideally, you should store extra nutrients in a location or environment where they're not able to freeze. However, as long as you allow the nutrients to defrost and shake them well before use, they should be good to apply!

How to apply your extra nutrients

You’ve got the leftover pouches from last year and need to determine the best ways to incorporate them into your current subscription or the upcoming season’s plan. We got you covered.

1

Determine your grass type

Do you have warm-season grass or cool-season grass? This will help determine the best time to apply leftover nutrients to your grass.

Know when to apply for optimal results

If you have warm-season grass, late spring to mid-summer will be the optimal time to apply your leftover pouches. Applying during this time will allow for an added boost of nutrients to grass during the peak period for root and shoot growth for warm-season grasses.


If you have cool-season grass, either spring or fall applications will be the optimal time to apply. Applying in the spring will support increased shoot growth, whereas applying in the fall will support deeper root growth.

Apply alongside your current nutrient plan

  1. We recommend always applying your active Sunday custom lawn plan pouches first.
  2. Wait a minimum of 7–10 days between your current plan application and the application of leftover nutrients.
  3. Now apply your first leftover nutrient application.
  4. If you have more than one leftover nutrient pouch, continue to alternate the leftover pouches in between your active subscription.
