Commercial Horticultural Consulting

Leslie F. Halleck, Senior Horticulturist. M.S., CPH

As a degreed and Certified Professional Horticulturist (ASHS), Leslie provides horticultural consulting to commercial clients such as greenhouse growers, landscape architects, design & build firms, landscape maintenance companies, and companies that create horticultural products. We support your work with site and plan review, plant recommendations, design enhancements and adjustments, maintenance recommendations and plans, greenhouse production improvements, grow lighting plans, product sourcing, technical copywriting, and product development support. Consulting can be as-needed or with ongoing monthly retainers.

Leslie can plug-in to work directly with you and your staff on your needs, or help you by communicating directly with your client. Leslie's extensive sales and management experience comes in handy. Sometimes when you need to tell your client "no, that won't work" it can be helpful to have a CPH to back you up. Conversely, when you need to sell a great idea or solution, a CPH's stamp of approval can close the deal.

Leslie takes a no-nonsense approach to horticulture; if you have a plant where it shouldn't be, or a lawn that's just not going to grow in the shade, she won't mince words about it and she won't promise you it can be fixed if she doesn't believe it can be. You'll always get direct and accurate advice as to action you need to take to get your project on track.

As a CPH, Leslie is also qualified to provide detailed reports that can be used for documentation, legal research or reports, legal claims, or expert testimony.

Consultations can be conducted on-site, in our office in East Dallas (near The Dallas Arboretum), or online or phone when applicable. Leslie's consulting services can be hired as needed or with an ongoing monthly retainer.  Leslie has a 2-hour minimum for on-site consulting services, plus travel time. Ongoing consulting is billed in 1-hour increments.
