Planning Your Vegetable Garden

Know Your Location
Herkimer County spans multiple plant hardiness zones, from 5b to 4a. These zones indicate the coldest temperatures and the timing of first and last frosts, which are crucial for determining what vegetables will thrive and when to plant them. Consult a plant hardiness map to identify your garden’s zone and create a planting schedule accordingly.

Soil conditions in Herkimer County vary. The rich, loamy soil of the Mohawk Valley supports a wide range of crops, while the sandy Adirondack soils may require amendments like compost and topsoil to enhance productivity. In early spring, consider taking a soil sample to the Herkimer CCE office for analysis to determine necessary amendments for optimal plant growth.

When selecting a garden location, assess the following: 

  • Sunlight: Ensure the site receives at least eight hours of full sun daily, avoiding areas shaded by trees or buildings.
  • Drainage: Choose a well-drained area free of standing water.
  • Accessibility: Position your garden near a water source to make irrigation easier, especially during dry summer months.

Decide What to Grow
Choosing the right vegetables depends on several factors:

  • Suitability: Will they grow well in your soil and climate?
  • Preference: Will your family enjoy eating them?
  • Disease Resistance: Are there common plant diseases in your area that could affect certain crops?
  • Maintenance: Some crops require frequent care, while others need minimal attention. Consider your availability for watering, weeding, and pest control.


Winter is an excellent time to browse seed catalogs, which provide valuable information on plant varieties, days to maturity, yield expectations, storage life, and disease resistance. In the Mohawk Valley, selecting early-ripening and disease-resistant varieties can increase your garden’s success.

Seed types include: 

  • Open-pollinated: Naturally pollinated varieties that produce seeds you can save and replant.
  • Heritage (Heirloom): Open-pollinated varieties cultivated for at least 50 years, often prized for their superior flavor.
  • Hybrid: Crossbred for specific traits like disease resistance or high productivity; however, seeds from these plants may not retain the same characteristics.

Start Your Seeds Indoors

Starting seeds indoors can give your plants a strong head start, particularly in Herkimer County’s short growing season. Follow these steps:

Gather Your Supplies

You’ll need seed trays or small pots, a quality seed-starting mix, labels, and seeds. A grow light and heat mat are essential to maintain consistent germination temperatures. While some guides suggest using a windowsill, Herkimer County’s cloudy, cold conditions make this less effective.

Plant Your Seeds

Refer to this Cornell guide for a seed-starting calendar: Cornell Vegetable Gardening Guide. Fill trays with seed-starting mix, leaving about an inch of space at the top. Plant seeds at the recommended depth, usually about twice the seed’s diameter. Keep the soil moist but not waterlogged to prevent rot.

Care for Your Seedlings

Once seeds germinate, remove any covering to improve air circulation. Rotate trays daily or adjust grow lights to prevent seedlings from leaning. Thin out weaker seedlings to allow the strongest ones to thrive. Maintain consistent moisture and begin fertilizing with diluted liquid fertilizer once seedlings develop their first true leaves.

Harden Off Before Transplanting

Before moving seedlings outdoors, gradually expose them to outdoor conditions through a process called hardening off. Start by placing them outside in a sheltered area for a few hours each day, gradually increasing exposure to sunlight and wind over one to two weeks. This step helps prevent transplant shock and ensures successful outdoor growth.
