Spring Gardening Tips

A little research, garden preparation, and a collection of seeds are all you need. Here are some tips for planting an early spring vegetable garden:

Prepare the Garden Beds:

If you haven’t done so already, go ahead and clean up your gardening beds by pushing aside last year’s mulch to help the soil warm up, remove dead plants and weeds, and top dress with a few inches of finished compost.

• Tips for Tidying the Garden

Know Your Average Last Frost Date:

The key to planning your garden is to have an idea of when the average last frost date is for your growing area. Read on for tips for find your average last frost date and how to develop a seed starting and planting schedule:

• How to Develop a Seed Starting Schedule

Read the Seed Package:

Most seed packages will include information on how and when to start seeds, the number of days to seed germination, and days to harvest.

Some seeds can be started early indoors under lights and then transplanted to the garden, while some seeds can be directly sowed into your garden beds. The seed packet will explain when to sow seeds and transplant seedlings with phases similar to:

• Start seeds indoors under lights # weeks before your last frost date: Some crops need a head start and should be sowed indoors. Once you have found your average last frost date, count back the number of weeks stated on the seed package. Sow seeds in seedling trays under lights, and then refer to the seed package to figure out when to transplant hardened off seedlings into the garden.
• Sow seeds as soon as the ground can be worked: After the snow melts, soil needs a few weeks to warm up and dry out a bit. Squeeze the soil in your hands. If it stays together in a wet clump, it will need to dry out a little further. You can use a meat thermometer to check the soil temperature. Most cool season crops will germinate when the soil temperature is around 40˚F.
• Direct sow seeds # weeks before your last frost date: Find your last frost date and calculate back the number of weeks indicated on the seed package.
• Sow seeds after your last frost date: Wait about a week until your average last frost date is past before sowing seeds for these crops.

Packets will also note spacing requirements, height and spread at maturity, thinning instructions, growth habit, and other special considerations.

Decide How to Plant Your Seeds:

You can sow your seeds in a variety of ways. Some seeds will produce quicker if you start them indoors under lights and transplant to the garden in early spring. Indoor seedlings will need to adjust to outdoor weather before planting. This process is called, “Hardening Off.”

• How to Harden Off Seedlings Before Transplanting

Most spring crops can be planted by seeds sowed right in the garden in furrows, mounds, or simply by poking holes in the soil and dropping in the seeds. Here are some common methods plus tips for direct sowing seeds:

Watch the Weather:

Even though these vegetables are cold tolerant, they can still be stunted or killed by a severe drop in temperature. Be ready to protect your plants if the weather threatens with an unanticipated freeze.

Keep the Soil Evenly Moist:

After sowing seeds, water the soil well and keep evenly moist until the seeds sprout. Take care not to over water, as seeds will rot in waterlogged soil. Once the plants begin to grow, let the soil dry slightly between watering.

Harvest Frequently:

Most cool season crops will begin bolting, or go to seed when the weather gets too warm. Bolting happens when the plants are triggered to go to seed. The plant switches from growing foliage to setting seeds. The plant will send up a flower stalk that will develop into seeds. Usually, the foliage turns bitter once the plant bolts. Either let the seeds mature so you can save them for next year, or pull the plants and sow something new.
