Description
Description
GardenPRO Perennial & Container 14-14-16 Slow Release is a controlled release fertilizer for perennials and container plants, designed to provide season-long nutrition in gardens, planters, and baskets.

This slow release formula is positioned as a proven 3–4 month option, giving you a predictable window of steady nutrient availability through the main part of the growing season. If you maintain mixed perennial borders and container displays at the same time, this product keeps your fertilizer choice simple: one perennial and container fertilizer that matches both planting styles without switching products.

The balanced 14-14-16 NPK is stated right in the product name and supports general, all-around plant nutrition rather than pushing a single outcome. That makes it a practical fit when your goal is consistent growth and dependable performance across a range of perennial types and container arrangements. It’s also a straightforward choice for gardeners who want a slow release fertilizer that’s easy to shop by category: controlled release fertilizer, perennial fertilizer, and container plant fertilizer.

GardenPRO Perennial & Container 14-14-16 Slow Release is also clearly aligned with spring timing for garden maintenance. For many gardens, spring is when perennial beds and seasonal container plantings get refreshed, and a 3–4 month controlled release window fits neatly into that early-season planning. Because it’s intended for both landscape and container settings, it’s well suited to patios and entry planters alongside in-ground perennial beds, helping you keep nutrition consistent across the spaces you actually look at every day.

GardenPRO Perennial & Container 14-14-16 Slow Release is a good fit for gardeners who want a controlled release, slow release fertilizer for all perennials and container plants, especially when you prefer a proven 3–4 month season-long nutrition approach with a simple, balanced 14-14-16 profile.

Frequently Asked Questions
Why is total nitrogen (N) important for plant growth, and what makes it different from other nutrients?

Total Nitrogen is important because it directly drives leafy growth, chlorophyll production, and overall growth speed, which sets the pace for the entire plant. It’s unique because the “total” number can include different nitrogen forms that behave differently in the root zone, meaning the same total amount can produce very different results depending on the nitrogen type and plant stage.

What Is ammoniacal nitrogen (N) and why do plants need It?

Ammoniacal Nitrogen (N) is a plant-available form of ammonium (NH₄⁺) that provides a steady, gentle source of nitrogen for healthy green growth. Unlike fast-release nitrogen types, ammoniacal nitrogen feeds plants slowly, helps stabilize root-zone pH, and works well in cooler temperatures. It is commonly used during early vegetative growth because it supports strong leaf development without burning young roots. If plants show pale leaves, slow growth, or weak stems, they may need more available ammoniacal nitrogen.

What does nitrate nitrogen (N) do for plants?

Nitrate Nitrogen provides a stable, easy-to-absorb form of nitrogen that supports steady growth, strong foliage, and reliable plant development without sudden nutrient swings.

Read the full guide

What does available phosphoric acid (P₂O₅) do for plants, and how is it different from available phosphate?

Available phosphoric acid provides a fast-absorbing form of phosphorus that fuels root growth, energy transfer, and strong flowering. It becomes part of the plant’s total available phosphate supply, but the two terms are not the same—available phosphoric acid is one source of phosphorus, while available phosphate refers to the entire pool of plant-available phosphorus overall.

Read the full guide

Why is soluble potash (K2O) important for plants?

Soluble potash (K2O) is important because it helps plants control water use, move sugars to new growth and fruit, and build stronger, higher-quality structure under stress. It’s unique from many other nutrients because it acts more like a regulator and transport helper than a direct “building material,” so the biggest benefits show up as steadier growth, stronger stems, and better finishing instead of just bigger leaves.
