Jobe’s Slow Release Evergreen Fertilizer Spikes, Easy Plant Care for Cypress, Arborvitae, Pine, Cedar, and Many More Acid Loving Trees, 15 Count

Each package contains 15 spikes, simplifying application and ensuring a steady supply of nutrients directly to the plant roots. The spikes have a 13-3-4 NPK ratio, which is beneficial for root development and plant growth but may not be perfectly balanced for hydrangeas specifically, which often benefit from a higher phosphate content for better blooming.

Buying Guide for the Best Fertilizer For Hydrangeas
Choosing the right fertilizer for your hydrangeas is crucial to ensure they grow healthy and produce beautiful blooms. Hydrangeas have specific nutrient needs, and understanding these needs will help you select the best fertilizer. When picking a fertilizer, consider the type of hydrangea you have, the soil condition, and the desired bloom color. Here are some key specifications to consider when selecting a fertilizer for your hydrangeas.N-P-K RatioThe N-P-K ratio represents the percentage of nitrogen (N), phosphorus (P), and potassium (K) in the fertilizer. Nitrogen promotes leaf growth, phosphorus supports root and flower development, and potassium enhances overall plant health. For hydrangeas, a balanced ratio like 10-10-10 or a bloom-boosting formula like 10-20-10 can be beneficial. If you want more foliage, go for higher nitrogen; for more blooms, choose higher phosphorus. Assess your plant's current growth stage and needs to determine the right ratio.
Type of FertilizerFertilizers come in various forms, including granular, liquid, and slow-release. Granular fertilizers are easy to apply and provide nutrients over time. Liquid fertilizers offer quick absorption and are ideal for immediate nutrient needs. Slow-release fertilizers gradually release nutrients, reducing the risk of over-fertilization. Choose granular or slow-release for steady growth, and liquid for a quick nutrient boost. Consider your gardening routine and how often you can fertilize when selecting the type.
Soil pH AdjustersHydrangeas can change color based on soil pH. Acidic soil (pH below 6) produces blue flowers, while alkaline soil (pH above 7) results in pink flowers. Some fertilizers include pH adjusters to help you achieve the desired bloom color. If you want blue flowers, look for fertilizers with sulfur or aluminum sulfate. For pink flowers, choose those with lime. Test your soil pH before selecting a fertilizer to ensure it aligns with your color preference.
Organic vs. SyntheticOrganic fertilizers are made from natural materials and improve soil health over time, while synthetic fertilizers are chemically formulated for immediate nutrient availability. Organic options, like compost or manure, are environmentally friendly and enhance soil structure. Synthetic fertilizers provide precise nutrient ratios and faster results. If you prefer a natural approach and long-term soil benefits, go organic. For quick and targeted feeding, synthetic fertilizers are a good choice.
MicronutrientsIn addition to the primary nutrients (N-P-K), hydrangeas also need micronutrients like iron, magnesium, and calcium for optimal growth. Some fertilizers include these micronutrients to prevent deficiencies and promote overall plant health. Check the fertilizer label for a comprehensive nutrient profile. If your hydrangeas show signs of nutrient deficiency (e.g., yellowing leaves), choose a fertilizer with added micronutrients to address these issues.
