  • How Do I Apply the Product?
    Retrosance’s liquid treatment plan will always come with a set of instructions. However, we understand that sometimes those can get lost! If that is the case, please see below for how to apply: 1. Initially, you will want to spray your lawn or garden with water to prepare the soil. Please ensure to water everywhere you intend to apply Retrosance products, for at least 1-2 minutes. 2. Uncap your bottle, and securely screw on the bottle to the bottom end of the sprayer. 3. Next, securely attach your hose onto the remaining screw-in portion of your sprayer nozzle (to suit a typical garden hose 5/8” thread.) 4. Make sure the sprayer is oriented to the “on” position and then turn on your water. 5. Apply generously and evenly to the desired area of application, and use up the entire bottle. 1 bottle will cover approx. 5,000 sq ft. (Please see the FAQ section of our website for further advice relating to larger or smaller lawns or gardens, adaptations and much more.) 6. Repeat these application instructions for your other bottle if included in your package this month. QUICK TIP: Preferably apply in the morning or the next best option, in the evening (avoiding the hottest part of the day), i.e. never between 11am-5pm. This invites sun damage if applied when it is too warm.
  • Can I use this on Cactus & Succulents
    Yes! Retrosance products can be used on all plants. Please see our question "Can I use this on potted plants?" for more details.
  • Can I use Retrosance on Potted Plants?
    YES! Absolutely! Our products are great for all plants, including potted plants. To apply simply add 4-8 oz (1/2 up to 1 cup if you want it more concentrated) into 1 gallon of water and mix. Apply this water/liquid soil amendment mixture onto your plants when you water them. Repeat this process at least once a week. For cactus and succulents, make sure to add this water mixture straight into the soil (below the crown of the succulents, or at the base of the cactus) in order to avoid getting the plant itself wet and potential sun damage.
  • How Often Do I Apply Product on my Lawn or Garden?
    We will send you a new package of products to apply, every month. The unique thing about our program is that we understand that plant's have different needs throughout the growing season-- so their food should change according to those needs! Each month has been carefully analyzed against season, weather, temperatures, growth cycles, and use (grass) or harvesting (gardens). As such, we send you the exact products your plant's need in that very moment. We recommend you apply the product you get for the month, during that month we sent it to you.
  • What if a Piece of my Sprayer Comes off When Screwing on My Bottle?
    This sometimes happens and is normal! We recommend just popping it back on by fidgeting with it until it comes back on. Some sprayer pieces are fidgety, but once popped back on it will work just the same!
  • Is it Possible to "Over-Apply" or Spray "Too Much" ?
    In short, no. It is not possible to over-apply or spray your lawn or garden "too much". Because we use all-natural ingredients in our products and our microbial products are all registered organic, you will not be exposed to any toxicities that need to be diluted out.
  • Can I use these products on anything besides grass?
    Yes! Retrosance's product line can be used on trees, shrubs, foliage, flowers, fruit and vegetable crops. Always read the instructions to make sure the product is applied correctly. Retrosance products can be applied alongside other soil treatments.
  • Why Do I Need to Re-Apply the products?
    Heat and water stress can cause microbes to die or become inactive. Mycorrhizae (beneficial plant fungus) helps your plants obtain water and nutrients that the plant roots would otherwise be unable to get. Microbes (including the ones that promote mycorrhizae growth) must be reapplied frequently in order to make sure the relationship between the mycorrhizae and plant roots are at its peak.
  • What if my Lawn or Garden is Bigger than 5,000 square feet?
    If you know you will be covering a larger area than the recommended "up to 5,000 sq feet", then we recommend ordering a second subscription that will cover up to 10,000 sq feet between both subscriptions. If you know you will be covering even more than that, please send us an email through our contact page and we will get you what you need through our commercial landscaping route at our best rates!
  • Can I Use This in the Winter?
    Yes! Winter is the perfect time to bring potted plants indoors, and to start seedlings for Spring! Because of this, we continue to send you product all year long (even in the winter) so you can be ready for Spring, and/or keep your potted plants thriving.
  • How Can I Tell if it is Working?
    There are several ways to know if it is working. You will notice an increase of root mass (bigger roots and/or more roots). Your plants will require less water as the roots will have access to more of the soil profile. Grass will recover from overuse faster, as the roots are able to better utilize the nutrients in the soil. Vegetables in your garden will look heartier and healthier. You will start to notice your lawn and garden leaves getting greener after about a week. It takes about 6 weeks time to notice a difference in root changes, but they will come!
  • Can I Pause my Subscription?
    Unfortunately, we do not have this feature at this time but hope to get it in the future as our business grows! For now if you do not wish to have product come to your home you will have to cancel your subscription. If you sign up again for our product you will be sent our starter pack and get right back on schedule!
