Fertrell Berry Mix


Blueberries – Blueberries thrive in acidic soil within the 4.5 to 5.1 pH range. The lower pH makes it difficult for the plants to utilize phosphorous. We recommend a one time application from July thru Sept feeding of Holly Care 4-6-4 to provide a high phosphorous fertilizer with the sulfur, nutrients and acidity that blueberries need with plenty of time for the roots to absorb them. In the early spring before leafs are fully out, apply Fertrell Berry Mix 4-2-4 to give the plants a boost prior to leaf and berry production. Use of hardwood sawdust for mulch will reduce the nitrogen intake of your plants, so additional nitrogen may be required.

“Brambles” Raspberries, Blackberries, Black caps, etc – In March apply Aragonite followed by an April application of Berry Mix 4-2-4. Then in Aug thru Oct apply Berry Mix 4-2-4 once to allow nutrients to be absorbed in the plants roots and help set the plants for heavy spring production.

Strawberries – Fertilize strawberries after the last harvest with Berry Mix 4-2-4 one time between July thru September before you mulch the plants. The fertilizer will more readily available to the plant roots if allowed to be absorbed directly into the soil while protected by the mulch. A spring application of Fertrell Liquid #3 applied on top of the mulch at a ratio of 75 parts water to 1 part fish will give the plants a boost prior to berry production and help wash the nutrients built up in the mulch to the plants.



The Fertrell Berry Program is designed for organic fertilizers and how they work with the different berry plants. The best times to fertilize are based on the plants needs and to allow the nutrients to be absorbed by the roots in time to have an impact on plant growth and berry production. Many of our fertilizers will work well for Berries but Fertrell Berry Mix 4-2-4 is specifically designed for berries with added zinc, boron, and sulfur. Typical analysis: 4-2-4.
