Visiting a specialty nursery at pot season

Most nurseries have a pot season: the weeks when the year’s work is actually made, seed sown, cuttings struck, liners potted and set out. Many specialty growers mark it with open days, sales or quiet invitations to walk the benches, because a gardener who has seen the propagating house never quite shops anywhere else again. Plan the visit around that season and you come home with more than plants: you come home with the standards against which every other nursery, catalog and garden center will afterwards be measured, and those standards are exactly what the specialty trade exists to keep alive.

Reading the nursery year

The year runs backward from sale. Woody stock sold bare root in spring was dug in autumn and heeled in through winter. Perennials sold in quart pots in May were potted as liners in March from divisions taken the previous summer. Cuttings struck in June are quarts by the following spring, and seed of slow species started this winter will not be for sale for two or three years. So the richest visiting windows are early spring, when potting is in full swing and benches fill, and late summer, when fields are at full growth and next year’s stock is being struck. In high summer the sales yard is at its prettiest; in pot season it is at its most honest.

The year, season by season

What the growing areas tell you

Walk past the register if you are invited to. Rows of stock plants, the mother plants from which cuttings and divisions are taken, tell you what the nursery actually grows versus merely resells. A propagating house with mist benches and trays of struck cuttings is the workshop of the trade; labels with dates and seed lot numbers are the handwriting of real record keeping. Weed-free aisles, hose reels run properly and quarantine benches for new arrivals are the boring virtues that keep viruses and weeds out of what you carry home. Read the fields the same way: rows of one variety running the length of a field mean the nursery plants its own crop; a few of everything in short rows means it buys in what it sells, which is not a scandal, only a different trade with different answers to every question you are about to ask.

The etiquette of a working nursery

Open days run on good manners, and the manners are short enough to list:

• Stay on the paths; foot traffic compacts liner beds and carries disease in.
• Ask before photographing inside propagation houses, where unreleased varieties live.
• Handle plants at the benches, but ask before lifting anything from the fields.
• Buy something, even small; the visit costs the nursery its workday.
• Respect the closing hours of a family operation, where the potting waits for you to leave.

Mistakes to avoid

Visit mistakes waste the rare access an open day grants. Going at the prettiest week instead of the most honest one, and seeing only a shop. Asking the sales desk questions meant for the propagator, then leaving with a shrug. Buying plants in bloom because bloom is certain, over fresh-potted liners that establish better. Photographing trays of unlisted seedlings and posting them, which is how a grower loses control of an unreleased variety. And arriving without a question written down, so the whole drive home is spent remembering it.

Bringing the visit home

The plants you carry back from pot season are usually young, fresh-potted and full of running, which is exactly what you want: plant them promptly, water them in, and let them make their growth in your soil rather than a sales yard. Note what you learned in the garden diary beside the planting calendar for the season, and the visit keeps working for years: the bench numbers, the wintering answers and the names of the stock plants all stay useful long after the plants themselves have settled. A specialty nursery seen at work turns from a shop into a correspondence, and the correspondence is the part that improves your garden.
