GARDENWISE 13-13-13 Slow Release Granular Fertilizer 4-Quart — All-Purpose NPK for Lawns, Gardens

GARDENWISE 13-13-13 Slow Release Granular Fertilizer is a balanced, all-purpose granular plant food that feeds outdoor lawns, vegetables, flowers, shrubs, and trees for up to eight weeks with one application.

This 13-13-13 formula delivers equal parts nitrogen, phosphorus, and potassium in a slow-release form designed to supply steady nutrition without frequent reapplication. The coarse, easy-to-spread granules work well across turf, garden beds, containers, and ornamentals, helping establish roots, support green growth, and improve overall plant vigor. Packaged in a convenient 4-quart size, it’s a versatile option for small to medium-sized yards and garden projects.

How does this fertilizer help my lawn and garden throughout the season?

The balanced nutrients support multiple plant stages: nitrogen for leaf and turf growth, phosphorus for root development, and potassium for stress tolerance. The slow-release carrier gradually makes nutrients available, reducing the risk of burning and minimizing nutrient spikes. This steadier feeding pattern keeps plants supplied without constant attention.

• Feeds for up to eight weeks per application
• Suitable for turf, vegetables, flowers, shrubs, and trees
• Reduces frequency of applications compared with quick-release formulas

How do I apply GARDENWISE 13-13-13 to different plants and containers?

Application is straightforward: broadcast evenly over lawns with a spreader, work lightly into garden soil around flowers and vegetables, and sprinkle on top of potting mix for containers. Follow package rate recommendations for square footage or container volume to avoid overfeeding. Watering after application helps move nutrients into the root zone.

• Use a broadcast spreader for lawns and large areas
• Apply by hand or with a scoop around garden beds and shrubs
• Lightly water after applying to activate the slow-release granules

What makes the slow-release formula better than quick-release options?

Slow-release granules reduce nutrient surges and lower the chance of burning tender roots or foliage. They provide a predictable, sustained supply of N-P-K so plants can take up nutrients as they need them. This also means fewer applications and less time spent managing feed schedules.

• Less risk of fertilizer burn compared to fast-release products
• Steady nutrient availability supports long-term plant health
• Requires fewer applications — saves time and effort

Can I use this fertilizer with vegetables and flowering plants?

Yes—its balanced 13-13-13 ratio is intended for a wide range of outdoor plants, including vegetables, herbs, roses, and bedding plants. It supports root establishment and above-ground growth without favoring one growth type excessively. For flowering or fruiting stages, pair with targeted feeding schedules if you want to boost blooms or fruit set.

• Works for annuals, perennials, vegetables, and ornamentals
• Appropriate for container-grown plants as a maintenance feed
• Combine with specialty bloom or fruit fertilizers when needed

Who is this for: Gardeners, homeowners, and landscaping pros seeking a simple, dependable all-purpose fertilizer will appreciate GARDENWISE 13-13-13. It’s especially useful for people who want one product that covers lawns, beds, shrubs, and containers with minimal fuss. Choose the 4-quart size when you need a moderate supply for small yards, raised beds, or multiple potted plants.
