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.

Just don’t do it
Flavor Name: Original Coarse Sugar, Size: 1.86 Pound (Pack of 1)
Be aware this is like drinking dry grass and water that very quickly turns to gelatin. I can’t imagine the Navy seal that must be able to do this. You would have to be trained for torture in order to enter this stuff.. Unless you were hellbent on suffering, avoid this like the plague. Absolute waste of my money.

Great!
Color: 2-Pack White, Color: 2-Pack White
I wish I’d have taken a before photo. But imagine a bunch of spices, on a little spice shelf that makes a U formation and a bunch of spices in the middle. So many spices. So much maneuvering to find the right one. This- this is great! Organized, easy to see, reach. Neat. Excellent investment. It doesn’t even look like I have a lot in there, but I have 46 spices in there! And you’ll notice my cabinet has a lip. Easily fixed with a small piece of wood to raise the item.

Well thought out and easy to install
Color: 2-Pack Black, Color: 2-Pack Black
Definitely organizes and maximizes cabinet space for spice storage. It’s a little rickety. If you are using glass spice jars you will likely need to use the included screws into the cabinet because the double face tape it comes with might not hold up. It might work with the plastic spice containers, but even then it seems like it would not be sturdy enough to hold the weight. The instructions were clear and it installed quickly. If it lasts, it was definitely a value upgrade in my cabinet.

Don't buy the other brands
Color: 2-Pack Black
I'd give these a 10 if I could. I bought another version but returned ii because I didn't think it was very sturdy. These were only $8 more and what a difference. They are a very well made and a lot more sturdy. The extra $8 was a real bargain and well worth it.
