APPLICATION RECOMMENDATIONS
Test Your Soil
Maximum economic yield begins with a soil test to determine key soil nutrients your crops need. Your own experience, combined with soil testing is the first step to achieving a high yielding, high quality crop. Regular soil testing and the use of the appropriate Rainbow Plant Food grades will help you achieve complete nutritional balance for your crops.
Blueberries
Growing high-quality blueberries can be a tough task without the right fertilizer program. These berries are known for being sensitive to overwatering through irrigation, overfertilization, and elevated salt levels in the soil. Using a granular fertilizer can help reduce these risks.
Why is Rainbow Plant Food the granular fertilizer best suited for growing blueberries?
Blueberries are sensitive to overfertilization, so finding a balanced fertilizer is key to producing high-quality blueberries.
Every Rainbow Plant Food granule has the same amount of nutrients in it, which makes for consistent distribution of those nutrients to the plant. When these same nutrients are blended, they can segregate during transportation, handling and application, resulting in uneven distribution in the field.
Blueberries thrive in acidic soil (low pH – around pH of 5). When selecting a fertilizer source, find one that won’t alter soil pH. Rainbow Plant Food is a neutral salt and does not increase soil acidity, regardless of the amount applied.
Application Recommendation:
The best time to broadcast apply Rainbow Plant Food on blueberries is in the spring before the leaves have grown in. For new plants, a second application should be made in late spring to get them established. For established plants, only one application in early spring is needed.
Geographic location also plays a big role in soil type and will impact when the ideal time is for you to apply.
Talk to your local retailer or local extension office for specific recommendations.
