The flower food for bigger blooms
WonderFert Flower is a liquid fertilizer formulated to support greater blooming and flowering in your garden.
Specially formulated with higher phosphorus levels, it focuses resources directly on flower and fruit productivity. Its liquid formula absorbs quickly to kick-start growth, while its slow-release ingredients sustain growth. Need more flower power? The potassium and seaweed extract combination increases stress tolerance, so your plant can grow more vibrant blooms.
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:
- Specialized 3-8-7 NPK (Nitrogen-Phosphorus-Potassium) flower food
- Water and fertilize in just one step
- Made for roses, flowers, and flowering plants
- Encourages bigger flowers, greater yield and improves stress tolerance
- Safe for use on edible plants
- Non-staining formula
- 2 bottles cover up to 1,000 sq. ft.
- Includes concentrated plant food formula in 100% post-consumer recycled container and gentle garden hose-end sprayer
Ingredients:
Nitrogen: Slow-release fertilizer for sustained feeding
Phosphorus: For flowering and fruiting
Potassium and seaweed extract: For plant health and stress tolerance
Instructions:
- Best used in early spring until early summer, before peak heat. Apply during the early morning or late evening, and make sure the area is well-hydrated before application.
- Attach the hose-end sprayer to the bottle. Set the sprayer to the recommended setting for trees and shrubs.
- Spray evenly at the base of each tree and shrub. Avoid over-spraying—a few seconds per plant is sufficient.
- Water the treated area lightly to help the fertilizer penetrate the root zone.
- Reapply every 4-6 weeks during the active growing season to maintain optimal nourishment.

Great Product!
I've been using this for general purpose fertilizer for all my plants - works great and plants are thriving!
Was this review helpful?WonderFert Flower Garden Fertilizer
This product was amazing and easy to use! I noticed a big difference when using this fertilizer on my flowers because they were brighter, more colorful, greener, and just looked healthier. I would use this product again and again.
Was this review helpful?Fading foliage regenerated
My flower beds have started to fade over the years. Used the common miracle grow fertilizer and it never seemed to bring everything back to life. This is the first time I've used the wonderFert flower fertilizer and so far the foliage on my perennials is looking much greener than it has the past few years and peonies have a much fuller bloom. Ordered more of this to see the impact using for a full growing season.

This is my first time taking care of flowers, and I feel that this Sunday product is great for beginners as the organic base makes it very hard to harm a flower. Instructions are clear, and my roses look great.

Question: Will this discolor my cypress mulch? The Sunday Iron boost lawn fertilizer died my mulch grey and I had to replace it, want to make sure this doesn’t!!
Louisa D.
Great question! This product does not contain iron and will not cause staining.
Question: If I’m using the all purpose wert fert…. Do I need this flower one too, or is one or the other enough?
Louisa D.
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.
