Old Cobblers Farm™ Wicked Growth Nut Trees Fertilizer
Container nut tree fertilizer (5-5-10) for almonds, pecans, walnuts, and more. Application rates by pot size from Old Cobblers Farm.
Growing Guides & Fertilizer Education
Old Cobblers Farm™ Nut Tree Fertilizer is a container-specific 5-5-10 formula with elevated potassium for nut production in pots. Nut trees in containers face unique challenges — limited root space, faster nutrient depletion, and heat stress from container walls. The potassium-heavy ratio addresses these by strengthening stress tolerance and supporting nut quality.
The low nitrogen keeps growth manageable in containers, preventing the excessive shoot growth that can outpace root capacity in confined spaces.

What Is It ?
Old Cobblers Farm Wicked Plant Growth Nut Tree Fertilizer (5-5-10 NPK) is designed specifically for container-grown nut trees. This balanced formula with elevated potassium delivers steady nutrition to support root strength, flowering, and nut production in confined spaces. The double-potassium ratio fuels shell development and stress tolerance — critical for nut trees growing in containers where resources are limited. Whether you're growing a patio almond tree or a compact pecan, this blend ensures optimal health and resilience in sun-drenched pots.
When To Apply ?
Small containers (up to 5 gal): 1 tbsp. Medium containers (6-10 gal): 2 tbsp. Large containers (11-20 gal): 3 tbsp. XL containers (over 20 gal): ¼ cup. Apply every 4-6 weeks during growing season (spring through late summer). Reduce to every 8-10 weeks or discontinue during dormant season (fall-winter).
How to Apply ?
1.
Pre-Moisten
Water soil thoroughly the day before feeding to prepare roots for nutrient uptake and prevent burn.
2.
Apply
Evenly distribute fertilizer around the surface from 1 foot from trunk to drip line, avoiding direct trunk contact.
3.
Incorporate
Lightly mix into the topsoil layer with a rake to improve nutrient-soil contact.
4.
Water In
Water again to saturate the area and activate slow-release nutrients for sustained feeding.

How To Store
Store in a cool, dry place. Wear gloves if preferred. Keep away from children and pets. Ensure container drainage holes are open before fertilizing.
FAQs
1.
What is the best fertilizer for nut trees?
The best fertilizer for nut trees provides moderate nitrogen for canopy growth and higher potassium for nut development, shell hardening, and stress tolerance. A 5-5-10 ratio is ideal because the elevated potassium directly supports nut quality, size, and shell formation, while the balanced nitrogen and phosphorus sustain healthy tree structure and root systems. Nut trees in containers have especially high potassium demands since they rely entirely on supplemental nutrition. Old Cobblers Farm™ Wicked Growth Nut Trees Fertilizer 5-5-10 is specifically designed for container-grown almond, pecan, hazelnut, walnut, and other nut tree varieties.
2.
How do I fertilize nut trees in containers?
For container-grown nut trees, apply 1–3 tablespoons of 5-5-10 fertilizer depending on pot size (1 tbsp for small containers up to 5 gallons, 3 tbsp for 11–20 gallon pots). Water the soil thoroughly the day before feeding, distribute the fertilizer evenly around the surface avoiding direct trunk contact, lightly mix into the topsoil, and water again to activate nutrients. Feed every 4–6 weeks during the growing season and reduce or stop during dormancy. Old Cobblers Farm™ Wicked Growth Nut Trees Fertilizer 5-5-10 delivers steady nutrition for healthy, productive container nut trees.
3.
When should I fertilize pecan and almond trees?
Fertilize pecan and almond trees during the active growing season from spring through late summer, applying every 4–6 weeks. Begin feeding when trees leaf out in spring and continue through nut development. Reduce or discontinue feeding in fall and winter when trees enter dormancy. Newly planted trees should be fed lightly starting 4–6 weeks after planting. Mature, fruit-bearing trees have higher nutritional demands than young trees. Old Cobblers Farm™ Wicked Growth Nut Trees Fertilizer 5-5-10 supports nut trees through every growth stage from canopy development to nut maturation.
4.
Why is potassium important for nut trees?
Potassium is critical for nut trees because it directly influences nut size, shell development, kernel quality, and overall tree resilience. Potassium activates enzymes involved in carbohydrate production and transport — the process that fills nut kernels with energy-rich oils and proteins. It also strengthens cell walls for harder, more protective shells and improves the tree's ability to tolerate drought, heat, and cold stress. Nut trees have some of the highest potassium demands of any tree crop. Old Cobblers Farm™ Wicked Growth Nut Trees Fertilizer 5-5-10 provides elevated potassium at 10% to meet these intensive demands.
5.
Can I grow nut trees in containers?
Yes, many nut tree varieties can be grown successfully in large containers, including dwarf almonds, hazelnuts, dwarf pecans, chestnuts, and pine nut trees. Choose containers at least 15–20 gallons in size with excellent drainage, use a well-draining soil mix rich in compost and perlite, and place in full sun. Container nut trees need regular fertilization since they cannot access nutrients beyond the pot. Repot every 2–3 years and prune to manage size. Old Cobblers Farm™ Wicked Growth Nut Trees Fertilizer 5-5-10 is specifically formulated for the unique demands of container-grown nut trees.
6.
What NPK ratio do nut trees need?
Nut trees perform best with a ratio that emphasizes potassium, such as 5-5-10. The moderate nitrogen (5%) supports steady canopy growth without excessive shoot production that can divert energy from nut development. The phosphorus (5%) maintains healthy root systems. The elevated potassium (10%) is the key nutrient — it drives nut size, kernel quality, shell hardness, and tree stress tolerance. This ratio ensures the tree focuses its energy on producing high-quality nuts rather than excessive foliage. Old Cobblers Farm™ Wicked Growth Nut Trees Fertilizer 5-5-10 provides the optimal nutrient balance for productive nut trees.
7
How do I know if my nut tree needs fertilizer?
Signs that a nut tree needs fertilizer include pale or yellowing leaves, slow growth, small or unfilled nuts, premature leaf drop, reduced nut production compared to previous years, and thin canopy density. Potassium deficiency specifically shows as browning or scorching along leaf margins. Nitrogen deficiency causes overall yellowing starting with older leaves. A soil test is the most reliable way to identify specific nutrient needs and avoid over-fertilizing. Old Cobblers Farm™ Wicked Growth Nut Trees Fertilizer 5-5-10 addresses the most common nutrient deficiencies in container-grown nut trees.
