Grow Trees from Seeds with Nick Wrenn

Each month, we share expert-led training sessions to help community orchard stewards grow and care for thriving fruit trees. On this page, you’ll find a recorded workshop, a summary of key takeaways, and additional resources to deepen your knowledge. Be sure to explore past workshops for even more insights into urban orcharding best practices!

Workshop Summary:

Getting Started

  • Outline your goals & resources

  • Start small - don’t overextend yourself

  • Decide on a focus area

  • Appropriate diversity of plants 

Basic Materials

  • Seeds, cuttings, or small plants 

  • Nursery Beds or Pots

  • Soil, Mulch & Compost

  • Irrigation

  • Browse Protection (Deer, Rabbit, Squirrels, etc.)

Seed Sources

Collect seed locally

  • Free, except for your time

  • Locally adapted seed (potentially)

  • Full control over quality

  • Grow seed processing skills

Buy seed from other nurseries

  • Instant access to seed in exchange for cash

  • Specific genetics not accessible locally

  • Questionable quality

  • Minimal seed processing skills required

Seed Storage

  • Each species is different

  • Some seeds require stratification (Hot or Cold) 

  • Some require scarification (Breaking Outer Layer: Water, Acid, File) 

  • Forest Service “Woody Plant Seed” Manual (Insert Link)

Where to grow your trees

Air Pruning Beds

  • Build frames

  • Fill with soil/compost

  • Degrades over time

  • Protects nuts from rodents

  • Tap root remains intact 

  • Easy to dig trees

In-Ground Beds

  • Prepare the soil once (kill grass/weeds)

  • Mound up organic matter

  • Improves over time 

  • Cover crop potential 

  • Nuts more exposed 

  • Easy to dig 

Pots

  • Pots are familiar to customers

  • Used pots are cheap

  • Fabric pot benefits

  • Root binding can be an issue

  • Almost anything can be a pot (milk crates/plastic cups/containers)

Soil, Mulch, & Compost

  • Use what is available locally

  • Preference: leaf compost, worm compost, wood chips 

  • Trees in pots are pickier than trees in beds

  • Do not use “hot” (high nitrogen) inputs

  • Heavy clay - drainage issues

  • Pure sand - won’t hold water

  • Beware of hay (weed seeds and spray contaminants)

Irrigation

  • Wells are nice

  • Rainwater also works

  • Hose and quality of life

  • Automated systems

Protection

  • Hardware cloth for rodents 

  • Plastic or electric deer fence

  • Welded wire for rabbits & groundhogs

  • Living fences & dead hedges

Taxes & Regulation

  • Each state is different

  • Living Soil Farm nursery is an LLC

  • Federal & State tax

  • Nursery inspections & licenses

  • US Plant Board 

Sowing Seed

  • Large seeds can be mulched heavily

  • Small seeds need intense care

  • Larger spacing = larger trees

  • Smaller spacing = more trees 

  • Rodents 

  • Fall plant or after the first frost 

Digging Up Your Trees

  • Slow and careful 

  • Straight shovel @ 90 degrees

  • Moist soil helps big time!

  • Trees can handle some root damage 

  • Water soak 

Tree Storage

Pots Over Winter

  • Need insulation from freezing

  • Keep the soil moist

Heeling Bare Root Trees

  • Tucking roots into loose soil 

  • Water deeply

  • Mulch

Finding Customers

  • Word of mouth

  • Facebook marketplace

  • Website 

  • Social media 

  • Other nurseries

  • Landscapers 

  • Municipalities

 

Tree Distribution

  • Roots can not dry out in transit

  • Pack in moist medium (compost, woodchips, leaves)

  • When shipping the medium must be inert (sawdust coco coir, peatmoss) 

About Nick Wrenn:

Nick Wrenn has always been connected to trees, from playing in the woods as a child to working as a landscaper near Philadelphia. After studying Civil Engineering and working in construction management, he shifted his focus to plants in 2020. Inspired by Dr. Elaine Ingham, he completed the Soil Food Web School foundations courses in 2021 and delved into permaculture, regenerative agriculture, and agroforestry. Over the past four years, Nick has held various roles on small-scale farms, co-run seed swaps, and established a tree nursery and food forest on his grandparents’ farm in Cedar Grove, NC, where he grows thousands of mostly native, food-producing trees. In 2024, he expanded to a second site in Bassett, VA, while continuing to explore sustainable tree-growing techniques.
