Our Berry Fertilizer 8-12-12 is a premium blended fertilizer formulated specifically for berry plants. With an ideal nutrient ratio for strong root development and heavy fruit production, this mix ensures your berry plants get exactly what they need at the right time.

The 8% nitrogen fuels early season growth, helping plants establish lush, sturdy foliage. The 12% phosphorus supports vigorous root expansion and boosts bloom and fruit set — a must for blackberries, raspberries, and strawberries. With 12% potassium, this blend strengthens plant structure, improves drought tolerance, and enhances overall fruit quality.

This formula contains a targeted blend of muriate of potash, potassium sulfate, and potassium nitrate to give berry plants an immediately available and long-lasting source of potash. It also includes a robust micronutrient package with calcium, magnesium, sulfur, iron, manganese, zinc, and copper, strengthening plant health and preventing common deficiencies that limit berry yield and flavor.

This fertilizer is easy to apply and provides predictable, dependable nutrition for berry growers of all experience levels. Whether you're growing in rows, raised beds, or a backyard berry patch, this 8-12-12 blend delivers powerful results.

Berry Fertilizer Use Recommendations

For best results, apply the fertilizer uniformly around each plant. Adjust the rate based on plant size and age:

Application Rates

  • LOW Rate: Use for newly planted berries and small plugs.
    Low = ½ teaspoon per plant

  • MEDIUM Rate: Use for plants that have been established 1–2 years.
    Medium = 1 tablespoon per plant

  • HIGH Rate: Use for large, well-established plants.
    High = 4 tablespoons per plant

How to Apply

  • Sprinkle the recommended amount evenly around the base of each plant.

  • Lightly work the fertilizer into the top 1–2 inches of soil.

  • Water thoroughly after application to activate nutrients.

Seasonal Timing

  • At Planting: Use LOW rates for young plants or plugs being transplanted.

  • Early Season: Apply MEDIUM rates once plants begin active growth.

  • During Fruiting: Apply HIGH rates to support fruit load, size, and flavor.

  • Repeat: Every 4–6 weeks throughout the growing season as needed.

Container Berry Plants

  • Apply ½ tablespoon per gallon of container size (e.g., 2–3 tbsp for a 5-gallon pot).

  • Mix into the soil surface and water well.

Design Is Great. Material Was A Very Poor Choice.
Color: Black, Size: 7.9" x 3.7" x 6.2"
The gauge of the wire used is pretty thin. There is no real weight to this item. It does do exactly what I need it to do as it allows me to dry my dish cleaning brushes and my Dawn Puff brush in an organized manner. The taller basket is nice especially for my long handled brushes. It would actually be nice if there was a second basket since I have more handled brushes than anything else. I am also really happy that I went with this design where the drain pan is the entire length rather than a little spout where all the drainage is focused. The full length lines up better to usage of each individual brush. Due to its materials, I don't have much confidence in this being around long. So far, the black coating has held up and no r*sting (do not want to jinx myself) has occurred, but if and when it does, I fully expect the metal to fold like a house of cards. The design is actually great. The materials are its Achielles' Heel.

Great quality
Color: Black, Size: 7.9" x 3.7" x 6.2"
Great quality and super sleek to set up on the counter behind the sink. Got it for my mom as she always put her sponge in the sink and dishes ended up on top and you had to dig for the sponge. She has used this everyday since! It drains just like it states and doesn't keep water. Love how this saves the life of the sponges and space in the area.

Great organizer
Really happy with this little organizer. It’s the perfect size to sit next to my faucet, has a nice little drip tray, and is of good quality. Easily holds my dish soap, scrub daddy, and scrubber wand.

Handy and Functional
Likes-durable simplicity that holds and organizes sink side clutter. It’s cute for the kitchen with a farm, rustic, or industrial flair. Only dislike- the water tray is a little tricky to remove if you’re in a hurry. It’s not enough I wouldn’t worry about buying this again, but, you will have to pay attention to remove and replace it.
