Strawberries in pots fruit hard for their size and run their soil down fast, so they need steady feeding and a regular boost to keep the berries coming. This Strawberry Growing Kit is a complete four-part strawberry plant food system built for container strawberries, whether you grow them in a strawberry pot, a hanging basket, or a patio container. It covers the roots, the leaves, the blooms, and the fruit, with pre-measured packets and a weekly guide, so you get bigger, sweeter berries without the guesswork.

Key features

Container-optimized: dosed for 12 to 18 inch pots, strawberry pots, and hanging baskets, ideal for balconies and patios.
Four specialized formulas: an 18-6-12 slow-release granule for the roots, a 3-1-2 liquid NPK plant food for all-stage boosts, a trace element spray for green leaves, and a calcium spray for firmer, better-set fruit.
Exclusive weekly feeding guide: a streamlined care plan included in the kit.
Works on all strawberry types: June-bearing, everbearing, and day-neutral.
Beginner-friendly: easy pre-measured packets, no experience needed.

Ingredients

The four-product care system:

  • Slow-release NPK granule (18-6-12): 6 tbsp, net wt 3.0 oz, covers up to 4.2 sq ft. Poly-coated granules that feed the roots steadily.
  • Liquid NPK concentrate (3-1-2): 12 mL, a nitrogen-forward, all-stage liquid feed for a regular boost through continuous flowering and fruiting.
  • Essential trace elements: 12 mL. Iron, manganese, zinc, copper, and molybdenum for green leaves and vigor.
  • Calcium nutrient: 12 mL. Calcium, magnesium, and boron for firmer fruit and better fruit set.

How to use

Follow the included weekly guide. The four products work together across the season.

  1. NPK granule (18-6-12): spread evenly on the soil at the base of the plants, keeping it off the crowns, then water in. Do not apply it to the leaves. Reapply per the guide.
  2. Liquid NPK (3-1-2): mix as directed and apply like watering, weekly during active growth and fruiting, for a steady all-stage boost.
  3. Trace elements: apply as a foliar spray or a soil drench during growth and any time to correct yellowing.
  4. Calcium: apply as a foliar spray or a soil drench at bloom and as fruit sets, for firmer berries.

Why?

Container strawberries have shallow roots in a small volume of soil, and because they flower and fruit heavily and continuously, they draw that soil down quickly. This plant food kit covers both the steady base, from the slow-release granule, and the regular boost, from the liquid NPK, plus the micronutrients that keep leaves green and the calcium that firms the fruit. Together they support continuous flowering and larger, sweeter berries.

Makes how much?

Feeds strawberries grown in 12 to 18 inch containers, a strawberry pot, or a hanging basket for a full growing season, applied on the included weekly schedule.

Frequently Asked Questions

What is the best fertilizer for strawberries in pots?

Strawberries grown in containers need regular nutrition because nutrients wash out of potting soil more quickly than garden soil. The GrowScripts Strawberry Fertilizer Kit provides the nutrients needed to support healthy plants, abundant blooms, and larger, sweeter berries throughout the growing season.

Can I use this strawberry fertilizer kit on all strawberry varieties?

Yes. The kit works with June-bearing, everbearing, and day-neutral strawberry varieties. Whether you're growing Albion, Seascape, Chandler, Ozark Beauty, or another variety, the feeding program is designed to support healthy container-grown plants.

What size containers is this kit designed for?

This kit is optimized for strawberries grown in 12 to 18 inch containers, making it ideal for patios, balconies, decks, and other small-space gardens.

What comes with the GrowScripts Strawberry Fertilizer Kit?

Four products, a slow-release NPK granule, a liquid NPK concentrate, a trace element spray, and a calcium spray, along with an exclusive weekly feeding guide that removes the guesswork from growing strawberries. You'll know exactly what to apply and when for healthier plants and better harvests.

Is this a strawberry fertilizer or a plant food?

Both, since the terms mean the same thing. It is a complete strawberry plant food system that includes a slow-release fertilizer granule, a liquid feed, and micronutrient and calcium sprays, so whether you shop for strawberry fertilizer or strawberry plant food, this kit is what you are looking for.

Will this help my strawberry plants produce more fruit?

Proper nutrition is one of the biggest factors affecting flowering and fruit production. By providing complete nutrition throughout the growing season, the GrowScripts Strawberry Fertilizer Kit helps support vigorous growth, continuous flowering, and larger harvests when combined with proper watering and sunlight.

All about feeding container strawberries

Why container strawberries need regular feeding

Strawberries have shallow roots and, for their small size, they flower and fruit heavily, which makes them hungry plants. In a pot, they live on a small volume of soil that drains a little of its nutrition away with every watering, so a container strawberry runs short faster than one in the ground. Steady feeding through the season is what keeps the plants producing runners, flowers, and fruit instead of stalling.

Why strawberries get a four-part system

Most of your kits are three parts, but strawberries earn a fourth, the liquid NPK, because they fruit continuously rather than in one flush. The slow-release granule sets a steady nutritional floor, and the 3-1-2 liquid gives a regular, quick-acting boost that matches the constant demand of a plant that is flowering and fruiting at the same time. The trace spray keeps the leaves green, and the calcium spray firms the fruit, so all four cover a different part of the job.

June-bearing, everbearing, and day-neutral, and how feeding differs

Strawberries come in three habits, and it helps to know yours. June-bearing types produce one large crop in early summer, so they are fed steadily through the season with extra attention after they finish fruiting to build next year's crown. Everbearing and day-neutral types fruit in waves or continuously through the season, so they benefit most from the regular liquid boost that keeps nutrition steady during nonstop production. The kit supports all three, and the weekly guide keeps the rhythm simple.

Do not overdo the nitrogen

It is possible to feed strawberries too much nitrogen, and the result is a lush plant with plenty of leaves and runners but few berries. That is why this kit is measured and paced rather than heavy, and why the granule is not a high-nitrogen bag. Follow the guide rather than adding extra, since with strawberries more feeding does not mean more fruit past a point.

Pro tips for container strawberry care

Keep the crown at soil level, never buried, since a buried crown rots and an exposed one dries out.

Give strawberries full sun, at least six hours, for the sweetest fruit.

Water consistently, as shallow roots dry out fast in pots and uneven water stresses the plants.

Feed on the schedule rather than heavier, and lean on the calcium spray as fruit sets for firmer berries.
