When to Plant Zone 4 Vegetables?
A shorter growing season makes vegetable gardening more challenging in zone 4. However, by following a few tips, you can grow a bountiful harvest in zone 4. The key is to select vegetables that mature quickly.
Depending on where you live in zone 4, the last spring frost date is generally sometime in May while the first fall frost date is in September. Some longer season vegetable varieties may not have time to grow and produce vegetables before the first fall frost. When selecting vegetables to grow in zone 4, choose vegetable varieties with fewer days to maturity.
Many zone 4 gardeners start vegetable seeds indoors to get a jump-start on the gardening season. Start tender, warm-season vegetables such as tomatoes, peppers, eggplant, basil and summer squash indoors in April and transplant them to the garden after danger of frost has passed. Start broccoli, cabbage, Brussels sprouts and cauliflower seeds indoors, and transplant seedlings into the garden about two weeks before the last frost date.
In mid to late April, begin direct sowing lettuce, spinach, beets, carrots, collards, kale, radishes, peas and potatoes. To extend the harvest season, sow lettuce, beet, carrot, collard and radish seeds every two weeks through early summer. Plant cucumber seeds in May and squash seeds in late May.
Depending on where you live in zone 4, you can begin directly sowing bean and corn seeds into the zone 4 garden in mid to late May and early June.
The short growing season makes fall gardening a challenge. Directly sow lettuce, turnips, kohlrabi, spinach and kale in early August for a fall harvest. Row covers can help you extend the harvest.
How to Care for Zone 4 Vegetables?
Most vegetables need 6-8 hours of direct sunlight, about an inch of water weekly and fertile, well-drained soil. When gardening in zone 4, plant vegetables where they will receive direct afternoon sun.
Once your garden is planted and growing, these are a couple of tips for caring for your zone 4 vegetables.
- Inspect your plants several times a week for signs of disease and insect damage.
- Ensure that your plants get adequate water. During the hot days of summer or times of drought, rainfall may not be enough and you may have to water your plants.
- Keep your garden weed-free. Weeds can compete with vegetable plants for nutrients, choke out plants and spread disease.
- Fertilize your plants when needed. We recommend using slow-release, all-natural fertilizers.
- Mulching around your vegetable plants or between rows can help suppress weeds and retain moisture in the soil.
- Some crops may benefit from row covers. Row covers can protect plants from early spring or late fall frosts. Covers can also protect some plants from insect damage.
- Harvest vegetables before they become overly mature. Most vegetables are the most tender and flavorful before they reach full maturity.
What are the Best Early Spring Zone 4 Vegetables?
Perennial vegetables such as asparagus and rhubarb grow well in zone 4 and come back year after year. Both rhubarb and asparagus crowns are planted in the spring. Other early spring vegetables to grow in zone 4 are cabbage and broccoli (if started indoors) and lettuce, spinach, turnips, beets, radishes, peas, onions and carrots.
What are the Best Zone 4 Winter Vegetables?
Because the first frost usually hits zone 4 in September and freezing weather soon follows, vegetables don't grow well during the winter months. Using row covers can extend the harvest of cool-weather crops such as lettuce, spinach, beets and carrots. Parsnips can also be harvested in the fall, and sometimes later if covered with mulch. Crops such as Brussels sprouts and kale are often sweeter if harvested after a light frost. Zone 4 is excellent for planting hardneck garlic bulbs in the fall and harvesting the following summer.
