Bougainvillea Fertilizer by Nelson Plant Food - Slow Release Vine Food

In this review of Bougainvillea Fertilizer by Nelson Plant Food, the bottom line is clear: this granular, slow release formula is aimed at homeowners and casual gardeners who want bigger, healthier blooms with minimal fuss. The key reason to buy is the 17-7-10 nutrient balance combined with multiple nitrogen sources and sulfur and gypsum additions that work with soil biology to promote colorful, sustained flowering while reducing how often you need to fertilize.

Key Features

• Slow release feeding: Granular formula feeds plants over extended periods so you only need to apply every 14 days until blooms appear and then once a month during bloom.
• Balanced 17-7-10 formula: The NPK ratio is tuned to support vigorous growth and healthy, colorful bougainvillea blooms without excessive leaf growth at the expense of flowers.
• Multiple nitrogen sources: Four sources of nitrogen help maintain steady nutrient availability and reduce the risk of sudden flushes or nutrient stress.
• Soil health support: Added sulfur and gypsum help acidify and improve soil structure around roots, aiding nutrient uptake for vines.
• Versatile use: Designed for bougainvillea but suitable for a range of vining ornamentals, including mandevilla and wisteria, in pots, hanging baskets, or garden beds.

Who It's For

This fertilizer is best for homeowners and hobby gardeners growing bougainvillea or similar ornamental vines who want visible bloom improvement without frequent applications. It suits hanging baskets, potted specimens, and ground-planted vines where a granular slow release product is more convenient than liquid feeds.

Serious greenhouse growers or those requiring highly customized nutrient protocols might look elsewhere for adjustable liquid feeds and automated dosing, since the product is a pre-formulated granular option intended for straightforward maintenance and bloom promotion.

Pros & Cons

Pros

• Easy to use granular format that reduces watering and feeding frequency for busy homeowners.

• Includes sulfur and gypsum to help improve soil acidity and root zone structure for better nutrient uptake.

Cons
