Tomato Bed Wisdom from a Master Gardener

Our volunteers are awesome. We recently sat down with 16-year volunteer (and 2008 Volunteer of the Year) Sam Darin, pictured above, is famous for both his tool-sharpening skills (stop by for summer tool talk in the Fruit & Vegetable Garden on Thursdays, May through October) and his tomato-growing expertise.

Three heirloom tomato beds held 19 different varieties in the Fruit & Vegetable Garden this year. With harvest complete, the beds await their leaf mulch “blanket” for the winter.

We asked a timely question:  How does a Master Gardener (Sam was Illinois’ Master Gardener of the Year in 2010) put a vegetable garden to bed for the winter? His approach is so straightforward that even first-year gardeners can follow his lead:

1. After removing spent vegetables plants, pick up all leaves and fruit from the beds, clearing them of debris that might harbor diseases or pests.

2. AFTER the first hard frost, add a 4-6” layer of chopped leaf mulch to cover the beds for the winter. (Rake dry fall leaves and store them in a garbage can; use a mower or weed whacker to chop them.)

Mortgage Lifter
One of Sam Darin’s favorite tomato varieties, ‘Mortgage Lifter’ can weigh in at over a pound apiece.

3. Beyond the bed, continue to water shrubs and trees until frost. Late fall is usually quite dry, so it’s helpful to give larger plants a good drink before winter sets in.

As Sam says, “That’s about it.” Thanks, Sam, and see you at the Garden next spring!

An Autumn Surprise

colchicum
Crocus in autumn? No, it’s colchicum, a fall-flowering corm that holds quite a few surprises.

Every garden should hold a few surprises.

In fall, the Landscape Gardens deliver a good one: bright lavender patches of Colchicum, commonly known as autumn crocus or, less commonly, meadow saffron. Popping up suddenly through the groundcover, the flowers can stop visitors—and bloggers—in their tracks. With the current streak of balmy weather, the colchicum seem to be lasting even longer this year, begging a deeper look into the surprises that this bulb (actually a corm) holds up its leaves.

Surprise #1: It’s not a crocus.

Short, goblet-shaped flowers and spring-like color cause the confusion between colchicum and crocus, but there’s an easy way to tell them apart: count the long stamens in the center of the flower. Six stamens? It’s a colchicum. Only three? It’s a crocus. Colchicum’s flowers are much larger, too, and its leaves are long and strappy, rather than short and grassy.

Surprise #2: Spring leaves, fall flowers.

Expectations run high in spring, as colchicum’s wide leaves emerge, flowerless, to do their work, pulling sunlight’s energy into the corm underground. Then the leaves retreat for the summer. Time passes…and then the surprise comes, as clumps of flowers, leafless, emerge from the same spot in fall, a pleasing reminder that gardening is powered by patience.

Surprise #3: It’s not the source of saffron.

Although colchicum’s common name is “meadow saffron,” it doesn’t produce the flavorful red stamens of kitchen/culinary fame—that distinction belongs to Crocus sativus, a true crocus that also blooms in fall (along with its leaves—you can see why it gets so confusing). Unlike that crocus, colchicum has less showy stamens that cannot be eaten because…

Surprise #4: It’s poisonous.

The whole plant is: flowers, leaves, stamens, everything. Site it accordingly in your yard.

This weekend, three beautiful colchicum varieties will be sold at the Fall Bulb Festival—‘Lilac Wonder,’ which you can see in the Home Landscape Garden now; ‘Waterlily,’ a well-named, ruffled variety; and ‘Album,’ the classic white colchicum. Like most bulbs, colchicum corms are planted in late fall so they can settle in before next year’s bloom.

In the meantime, we wonder: what surprises does your garden hold?
