Work With Ed

Ed van Paassen · Plant Explorer

Independent horticultural expertise for the real world.

Plants, water and cultivation do not operate in isolation. I work with growers, horticultural companies, project teams and organisations that need experienced, practical plant expertise—from troubleshooting a crop to reviewing a horticultural or agricultural project.

When experience needs to meet the field.

A crop problem rarely respects professional boundaries. Plant physiology meets irrigation. Water management meets roots. Nutrition meets substrate, climate and cultivation practice.

That is where I work best: looking at the complete system, asking what the plant is telling us and translating technical knowledge into practical decisions.

Most assignments can be delivered remotely from the Netherlands: technical reviews, second opinions, crop and irrigation analysis, project advice and ongoing specialist support. When being on location adds real value, I can travel for focused site visits, field assessments, project milestones or training. This remote-first approach also makes international and African project collaboration practical without requiring continuous travel.

Areas for paid assignments

How I can contribute.

01 · PLANTS

Plant & Crop Troubleshooting

Independent assessment of plant-health, crop-performance and cultivation problems. A practical second opinion when the symptoms are visible but the cause is not.

02 · WATER

Irrigation & Root-Zone Assessment

Reviewing how water actually reaches and interacts with the active root zone, including irrigation practice, wetting patterns and the relationship between water, oxygen and plant performance.

03 · AGRICULTURE

Horticultural & Agricultural Projects

Technical review, field observation, practical feasibility and plant-production input for projects where agricultural ideas must work under real growing conditions.

04 · GREEN CITIES

Plant Expertise for Green Environments

Plant-focused input for urban greening, indoor planting and living-environment projects, with attention to species, growing conditions, water and long-term plant performance.

When to call

You do not need to know the answer before contacting me.

“Our crop is behaving unexpectedly and the obvious solutions are not working.”
“We need an experienced independent second opinion.”
“We are developing a horticultural or agricultural project and need specialist plant input.”
“Our irrigation system delivers water, but we need to understand what happens in the root zone.”
“We need someone who can bridge scientific knowledge and practical cultivation.”
“We have a green project and want the planting to work after installation—not only on the drawing.”
A straightforward approach

From question to useful action.

1. Show me the challenge.

Send a concise description, photographs, video or project information. For crop problems, context matters as much as the symptom.

2. Define what is needed.

We determine whether the right next step is a remote review, technical second opinion, site visit or broader project involvement.

3. Work toward the cause.

I look across the plant system rather than treating water, nutrition, roots and cultivation as unrelated subjects.

Remote-first, internationally available. Ed normally works from the Netherlands and travels when an on-location assessment, project milestone or training session genuinely benefits the assignment. African horticulture and agriculture projects are particularly welcome. Information shared for an assignment is treated confidentially.

Tell me what you are seeing, what you have already tried and what you need to decide. We can then determine whether my experience is a useful fit for the assignment.
