Old Cobblers Farm™ Wicked Growth Alpine/Rock Garden Plants Fertilizer

Product Overview

Description

Wicked Growth Rock Garden Fertilizer provides the restrained, phosphorus-focused nutrition that alpine plants and rock garden specimens require for compact growth and abundant flowering. The 5-10-5 formula delivers modest nitrogen to prevent leggy growth.

Rock garden plants evolved in harsh mountain environments with poor, rocky soils and minimal nutrients. They've adapted to thrive with less, and excessive fertilization produces weak, floppy growth that loses the compact, sculptural form that makes these plants valuable.

Essential for sedum, thyme, alpine pinks, hens and chicks, and other rock garden favorites. Keeps your rocky displays looking natural while supporting healthy flowering.

Highlights

• Low nitrogen for compactness
• High phosphorus bloom focus
• Rock garden optimized
• Alpine plant safe
• Natural form preservation

How to Apply

1-2 lbs/100 sq ft every 4-6 weeks. Severe deficiency: 2-3 lbs initially.

1

Action:

Survey garden bed and note deficiency symptoms. Map high-need zones.

Pro Tip:

Sandy areas and fruiting sections need more K than shaded areas.

Avoid:

Don't leave granules on surface in hot weather - damages plants.

2

Action:

Calculate 1-2 lbs per 100 sq ft. For 10x20 garden (200 sq ft), use 2-4 lbs.

Pro Tip:

Weigh fertilizer on kitchen scale. One cup 0-0-60 weighs ~0.5 lb.

Avoid:

Don't exceed 2 lbs per 100 sq ft per application. Split heavy doses.

3

Action

Broadcast granules evenly across soil surface. Work into top 2-3 inches with cultivator.

Pro Tip:

Sandy areas and fruiting sections need more K than shaded areas.

Avoid:

Don't spread on windy days - granules drift causing uneven application.

4

Action

Water thoroughly with 1-2 inches to dissolve granules and move K into root zone.

Pro Tip:

Incorporation prevents salt buildup and gets K to roots faster.

Avoid:

Don't leave granules on surface in hot weather - damages plants.

Key Benefits

Compact Growth Maintenance – Low nitrogen prevents the leggy, floppy growth that ruins the natural form of rock garden plants.

Enhanced Flowering – Elevated phosphorus supports abundant flowering in sedums, thymes, and other rock garden bloomers.

Drought Tolerance Support – Balanced potassium improves the drought tolerance these plants need in well-drained rock garden conditions.

Natural Form Preservation – Restrained nutrition maintains the tight, sculptural growth habits that make rock garden plants attractive.
