Beat the Heat — Plant These Cold Crop Veggies Now at Sunnyside Gardens

Spring is one of our favorite times of year here at Sunnyside Gardens. The soil is still cool, the days are getting longer, and your vegetable garden is full of potential. If you've been waiting for the "right time" to start planting — this is it.

The cold crop veggies at Sunnyside Gardens are ready to go — and they thrive in the conditions we have right now in Saratoga Springs: cool nights, mild days, and that fresh upstate New York air. These are the plants that want to go in the ground before summer heats up, and many of them will reward you again come fall when temperatures drop back down.

We've got everything you need in stock at Sunnyside Gardens, and our team is here to help you get it all in the ground the right way.

What Are Cold Crop Vegetables?

Cold crops (also called cool-season crops) are vegetables that germinate, grow, and even taste better in cooler temperatures — typically between 45°F and 75°F. Many of them can tolerate a light frost, making them ideal for our Saratoga Springs growing season (USDA Zone 5b), where spring can be unpredictable and fall comes early.

The bonus? These vegetables often develop sweeter, more complex flavors after a frost. Kale after a cold snap is in a completely different league than kale grown in summer heat.

Cold Crop Veggies We're Growing at Sunnyside Gardens

Here's a closer look at everything we currently have available — and how to get the most out of each one.

🥬 Lettuce

Best for: Salad lovers, container gardeners, beginners

Lettuce is one of the easiest and most rewarding cold-season crops you can grow. It prefers soil temperatures between 40°F and 65°F and bolts (goes to seed) quickly once summer heat sets in — so now is your window.

Plant it in full sun or partial shade and keep the soil consistently moist. For a continuous harvest, try succession planting: put in a new row every two weeks through late spring, then again in August for a fall crop.

Pro tip: Loose-leaf varieties like butterhead or oak leaf let you harvest outer leaves while the plant keeps growing — great for small gardens or raised beds.

🥦 Broccoli

Best for: Families, first-time vegetable gardeners, raised beds

Broccoli is a cool-weather superstar. It needs 60–80 days to maturity, so the earlier you get it in the ground, the better your spring harvest will be. Soil temperatures between 60°F and 65°F are ideal for transplanting.

Give broccoli plenty of sun (6+ hours) and consistent moisture. Side dress with a balanced fertilizer after transplanting to encourage strong heads. If a main head bolts before you harvest it, don't pull the plant — smaller side shoots will continue to produce for weeks.

Pro tip: Plant again in mid-to-late summer for a fall crop. Fall broccoli is often sweeter and less prone to pest pressure.

🥦 Cauliflower

Best for: Gardeners with a little experience, raised beds, longer growing seasons

Cauliflower is sometimes called the "fussiest" of the brassicas — it doesn't love wild temperature swings — but it's absolutely worth growing. It needs consistent cool temperatures and reliable moisture to form tight, white heads.

If you're growing white cauliflower, blanch the heads once they reach a few inches across: gather the outer leaves and tie them loosely over the head to protect it from sunlight. Colored varieties (purple, orange, Romanesco) are self-blanching and a little more forgiving.

Pro tip: Don't let cauliflower dry out. Inconsistent watering leads to loose or discolored heads. Drip irrigation or a good layer of mulch makes a big difference.

🥬 Cabbage

Best for: Preservers, fermenters, gardeners with space

Cabbage is a heavy producer and one of the most versatile vegetables you can grow. Whether you're making coleslaw, sauerkraut, or stuffed cabbage rolls, there's something deeply satisfying about growing your own heads.

Cabbage does best in full sun with fertile, well-draining soil. Space plants 18–24 inches apart — they need room to form solid heads. Water evenly to prevent heads from cracking, which can happen after heavy rain following a dry spell.

Pro tip: Cabbage is a favorite of cabbage worms and aphids. Check the undersides of leaves regularly and treat early with an organic option like neem oil or Bt (Bacillus thuringiensis) if needed.

🌿 Kale

Best for: Health-conscious gardeners, continuous harvest, fall growing

Kale might just be the toughest plant in this lineup. It laughs at light frost. It keeps producing even as other crops shut down. And as mentioned — a good cold snap makes it taste better, bringing out natural sweetness and reducing bitterness.

Plant kale in full sun to partial shade. Once established, it's relatively drought tolerant, though consistent moisture produces the most tender leaves. Harvest outer leaves regularly to keep the plant productive.

Pro tip: Plant a second wave in late summer for a fall and early winter harvest that just keeps going.

🌿 Swiss Chard

Best for: Colorful gardens, continuous harvest, heat-tolerant cool crops

Swiss chard is a bit of an overachiever — it tolerates cool and warm temperatures better than most cool-season crops, making it a reliable bridge between spring and summer. Bright Lights chard adds a pop of color to any garden with its rainbow of yellow, orange, red, and pink stems.

Sow seeds or transplant seedlings in early spring. Chard prefers full sun but handles partial shade. Harvest outer stalks when they reach 8–10 inches for a cut-and-come-again harvest that lasts all season.

Pro tip: Don't toss the stems — they're edible too, and delicious sautéed with a little garlic and olive oil.

🌿 Parsley

Best for: Herb gardeners, culinary use, container growing

Parsley is technically a biennial, but we grow it as an annual here in zone 5b. It's cold-hardy enough to go in the ground early and will keep producing well into fall. Both flat-leaf (Italian) and curly varieties do well in our climate.

Parsley prefers full sun and moist, well-drained soil. It can be slow to germinate from seed, which is why starting with transplants from the garden center gets you to harvesting much faster. Keep it from bolting by harvesting regularly.

Pro tip: Parsley is a host plant for black swallowtail butterfly caterpillars. If you see striped caterpillars on your plant, consider planting an extra one to share — and watch for the stunning butterflies that follow.

🌿 Celery

Best for: Experienced gardeners, long-season planners, soup lovers

Celery has a reputation for being demanding — and honestly, it's not wrong. It needs a long growing season (up to 130 days), consistent moisture, and cool temperatures. But homegrown celery has a depth of flavor that store-bought simply can't match.

Start celery early — it needs to be in the ground as soon as the soil can be worked. Keep the soil consistently moist (celery is mostly water, after all) and fertilize regularly. Blanching the stalks by mounding soil or wrapping them produces milder, more tender celery.

Pro tip: If you find celery too fussy, try leaf celery (also called cutting celery). It's much easier to grow and adds a punch of celery flavor to soups and salads.

🥦 Brussels Sprouts

Best for: Patient gardeners, fall harvest planning, unique flavor payoff

Brussels sprouts are the longest-season crop on this list — they can take 100–180 days to mature — and they're best harvested after the first fall frost, which sweetens them considerably. That means you're planting now for a harvest in October and November.

Plant in full sun in rich, well-amended soil. Keep them evenly watered and stake taller plants as they grow. As the season winds down and sprouts begin to form along the stalk, you can pinch off the top of the plant to push energy into the sprouts.

Pro tip: Patience pays off. Brussels sprouts are the one vegetable that genuinely improves the longer you wait — and after a hard frost, they're absolutely spectacular roasted with olive oil and a little balsamic.
