Fertilization of trees (and shrubs!) has never been easier

WonderFert Tree & Shrub is a specialized tree and shrub fertilizer designed to kickstart growth and support deeper rooting.

Our liquid fertilizer formula contains higher nitrogen, including 60% slow-release, and lower phosphorus and potassium to emphasize leafy growth and greening up of your trees and shrubs. It’s also formulated with essential micronutrients and humic acid to enhance fertilizer nutrients and uptake. With our liquid tree fertilizer, you can easily feed the root zone and maintain the health of all your beloved trees and shrubs.

At Sunday, we believe in creating fertilizers without pesticides or harsh chemicals—so you can enjoy your yard and get your hands dirty—not your plants.

Product Features:

  • 6-3-4 NPK (Nitrogen-Phosphorus-Potassium) liquid fertilizer for trees and shrubs
  • Water and fertilize all in one step with gentle garden hose-end sprayer
  • Promotes lush foliage and aids with nutrient deficiencies
  • 60% slow-release nitrogen sustained growth, iron for deep greening of foliage, and humic acid to aid nutrient absorption
  • Made for a wide range of trees and shrubs
  • Zero pesticides
  • Safe for use on edible plants
  • Easy application with hose-end sprayer for targeted feeding
  • 100% PCR recyclable and resealable container
  • 2 bottles cover up to 1,000 sq. ft.

Ingredients:

Nitrogen: Slow-release fertilizer for sustained growth

Phosphorus and potassium: for fruiting and flowering

Iron: For deep greening

Humic Acid: Aids in nutrient uptake

Iron, Zinc, Manganese: Essential micronutrients for healthy growth

Instructions:

  1. Apply early spring before leaf emergence until early summer before peak heat. Best used on well-hydrated woody plants during the early morning or late evening.
  2. Attach the hose-end sprayer to the bottle. Set the sprayer to the recommended setting for trees and shrubs.
  3. Apply to soil for 4-5 seconds at the base of each tree or shrub(s). Use the instructions on the label to apply the right amount—based on the height of the shrubs or the diameter of the tree.
  4. Water the application area lightly to help the fertilizer penetrate the root zone.
  5. Reapply every 4-6 weeks during the active growing season to maintain optimal nourishment.

Helpful Tips from Yard Advisors:

How does fertilization of trees promote healthy growth?

Fertilization of trees promotes healthy growth by supplying essential nutrients that strengthen roots, improve overall health, and enhance foliage.

What’s the difference between liquid tree fertilizer and tree fertilizer spikes?

Tree fertilizer spikes are solid, slow-release fertilizers that are driven into the soil around a tree, providing nutrients over an extended period. Liquid tree fertilizers, like WonderFert Tree & Shrub, are applied directly to the soil allowing for quicker absorption and more precise control of nutrient delivery. While both are effective, liquid fertilizers offer faster results and easier application for time-efficient tree nourishment.

Can this liquid fertilizer be used on all types of trees and shrubs?

It's suitable for most types, including evergreen, deciduous and flowering trees. However, it’s not labeled for palm trees, so we recommend finding a palm-specific fertilizer.

Is this a good fertilizer for fruit trees?

It's suitable for a range of trees, including fruit-bearing ones, and can aid in kick-starting growth and leafy growth for an extended period. The enhanced leafy growth helps support increased energy and sugar production, which are crucial for abundant fruiting. Pro tip: always ensure that the specific nutritional needs of your fruit trees align with the fertilizer's formula.

How to use with other Sunday products

If using other Sunday products, let liquid fertilizers dry completely before applying anything else to your garden. For best results, use our liquid garden fertilizer in combination with Sunday’s dry organic fertilizer, Soil Boost and weed control. This will help you fertilize plants properly, reduce weeds, and introduce nutrients back to your soil.

Easy to use

So many fertilizers are difficult to spread or get the measurements done right. You simply attach this to the hose and spray away. It seems this method gives a more even coat and they are actually getting the proper amount of fertilizer.
