PREMIUM CRAFTED EST. 1983 NELSON PLANT FOOD ColorStar slow‑release flower fertilizer 4 lb. — boosts bloom size & 4–5 month feeding

ColorStar is a nutrient-dense, slow‑release plant fertilizer designed to increase bloom size and flower count for indoor and outdoor ornamentals for 4–5 months per application.

Nelson Plant Foods ColorStar blends concentrated organic and mineral ingredients to support steady flowering without frequent feedings. Formulated with bone and blood meal plus multiple nitrogen sources and essential micronutrients, this 4 lb. formula feeds annuals, perennials, bulbs, and flowering shrubs to help them produce stronger, more colorful blooms while simplifying garden care.

How does ColorStar improve bloom size and quantity?

ColorStar supplies both macro- and micronutrients that flowering plants use to form larger, more vibrant blooms. Its combination of bone and blood meal and several mineral nutrients promotes sustained flowering rather than a quick, short-lived flush.

• Contains 25% bone and blood meal to support bloom development and flower set.
• Includes potassium nitrate and ammoniated phosphate to support flower formation and color intensity.
• Balanced release keeps nutrients available across the flowering cycle for extended results.

What makes the 4–5 month feeding schedule reliable?

The formula uses multiple nitrogen sources with staggered release rates so plants receive nutrients continuously instead of all at once. This reduces the need for repeated applications while maintaining steady growth and consistent bloom production.

• Seven nitrogen sources with different time‑release characteristics for uniform feeding.
• Slow release minimizes nutrient spikes that can harm sensitive flowering plants.
• Single application supports seasons of bloom depending on plant type and local conditions.

Can I use ColorStar on both indoor houseplants and outdoor garden beds?

Yes—ColorStar is formulated for versatile use on indoor flowering houseplants, container gardens, hanging baskets, and outdoor beds or shrubs. Apply according to label directions and adjust amounts for pot size or soil volume to avoid overfeeding.

• Suitable for annuals, perennials, bulbs, and flowering shrubs both inside and out.
• Apply measured amounts for containers versus in‑ground plantings.
• Compatible with routine watering schedules; avoid applying to waterlogged soil.

Which nutrients are included and why they matter?

Beyond nitrogen, ColorStar includes phosphorus and potassium sources plus trace elements that support color, foliage health, and overall plant vigor. Micronutrients like iron, zinc, and manganese help prevent common deficiencies that can dull flower color or reduce bloom count.

• Nutrient mix includes potassium nitrate, ureaform, ammoniated phosphate, and bone meal.
• Micronutrients: iron sulfate, zinc sulfate, copper sulfate, manganese sulfate, magnesium oxide.
• Calcium sources and oxysulfates improve structural strength and nutrient uptake.

Who this is for: ColorStar is aimed at home gardeners, balcony growers, and hobbyists who want fewer feedings and more dependable, showy blooms. It fits gardeners who prefer a concentrated, multi‑purpose fertilizer that covers several months of flowering—ideal for anyone managing containers, window boxes, seasonal beds, or mixed perennial borders who wants bigger, brighter flowers with less maintenance.
