Know before you buy
Petunias are iron-hungry plants that often develop yellowing leaves in standard soil. This formula includes an enhanced micronutrient package that provides the specific iron levels these plants need to maintain deep green foliage and consistent blooms.
Yes, this fertilizer is excellent for other iron-loving plants like calibrachoa and verbena. It is a versatile choice for any container-grown flowering plant that requires a boost in micronutrients.
The 20-6-22 formulation is specifically balanced to counteract the effects of hard water. It helps maintain the proper pH balance in your containers, ensuring that your plants can effectively absorb the nutrients provided.
Absolutely. Because hanging baskets have limited soil volume and require frequent watering, they often lose nutrients quickly. This professional-grade feed is designed to replenish those nutrients efficiently to support fuller growth and heavier flowering throughout the season.
The ratio indicates a high nitrogen and potassium content with low phosphorus. This balance encourages strong vegetative growth and vibrant flower production while preventing the excessive, leggy growth that can occur with higher phosphorus fertilizers.
