Greenhouse floriculture operation due diligence

Due diligence on a greenhouse floriculture operation means verifying which propagated varieties are protected under a breeder’s licence that won’t automatically transfer, checking the structure and heating system’s real condition, and confirming the garden-centre contracts are more than a handshake.

Reviewed

Once a letter of intent is signed on a greenhouse floriculture operation, diligence shifts from asking whether the business is attractive to verifying that everything described actually holds up on paper. Three areas matter most in this sub-sector: the licensing status of every proprietary or protected variety grown, the real physical and mechanical condition of the structure and its heating and lighting systems, and how much of the garden-centre and wholesale order book is documented versus dependent on the outgoing owner personally. A finding in any of these areas can change the deal’s economics significantly, which is why they deserve more attention here than the standard financial-statement review most acquisitions start with. This page walks through which documents to pull, which searches matter, which findings most often kill a deal, and what a given finding actually means once it surfaces.

Verifying variety licensing

Request a complete list of every variety grown, flagged for whether it is unprotected, protected under a breeder’s rights licence held by the business, or protected under a licence the seller merely believed applied. Where a licence exists, request the royalty payment history directly rather than accepting the seller’s statement that payments are current, since a lapsed royalty payment can put the entire propagation right at risk regardless of how the seller characterizes it. Confirm with the rights holder directly, if at all possible before closing, what their process is for reassigning the licence to a new operator and how long that process typically takes, since this single item can end up dictating the whole transaction’s timeline.

Verifying the structure and mechanical systems

  • An independent structural and mechanical inspection of the greenhouse, heating and lighting systems, rather than relying on the seller’s maintenance summary alone, since deferred maintenance in this sub-sector is easy to describe optimistically and expensive to discover after closing.
  • Several years of energy cost records, checked against weather data for those years, to separate a genuinely efficient system from one that simply had a few mild winters.
  • Any warranty or service history on major mechanical components, since equipment nearing the end of a warranty period close to closing shifts real cost risk onto the buyer.
  • A workers' compensation clearance check with the applicable provincial board, a standard due-diligence step for any facility-based business changing hands.

Verifying the garden-centre and wholesale order book

Request whatever documentation exists for each significant garden-centre or wholesale account — a written supply agreement, a purchase-order history, even email correspondence establishing a pattern — rather than accepting a customer list as proof of a relationship. Where an account is purely verbal and personal to the seller, treat that account’s continuation as uncertain rather than guaranteed, and factor that uncertainty into how the deal is priced or structured rather than discovering it after closing. Speaking directly with the largest few accounts, with the seller’s cooperation and before closing, is the most reliable way to test whether a relationship the seller describes as loyal is actually loyal to the business or loyal to the person running it.

What a licensing or structural finding actually means

Finding that a marquee proprietary variety’s propagation licence cannot be reassigned is not a paperwork problem — it means the buyer may be acquiring a business whose signature product they are not legally permitted to keep growing, which can be serious enough to reshape the entire deal rather than simply requiring a price adjustment. Finding a heating or lighting system nearing the end of its useful life just before a purchase closes means inheriting a major capital project in the first year of ownership, on top of financing the purchase itself, which changes the buyer’s real cash needs regardless of what the purchase price implied. Both findings are exactly why they belong in diligence rather than being left to discover during the first spring under new ownership.

Findings that most often end a deal

In practice, the deals that fall apart after an LOI in this sub-sector most often trace back to one of two discoveries: a licensed variety central to the spring order book that turns out to be non-transferable, or a garden-centre customer base that, once contacted directly, turns out to be considerably less committed to the business than the seller believed. Both are discoverable with direct verification rather than reliance on summaries, which is why buyers who start the rights-holder conversation and the customer-contact process early in diligence, rather than near the end, give themselves the most time to either resolve the issue or walk away before spending further on the deal.
