Let There be Light...for your Houseplants

I want to grow onions from seed. How early do I need to start?

Onion transplants can be grown in approximately 10-12 weeks. Sow seeds in late February or early March for planting outdoors in early May. Plant seeds ¾ inches deep in a seed-starting soil blend and keep them evenly moist. Once they sprout, provide the seedlings with bright light from a sunny, south-facing window, or better yet, provide supplemental light with fluorescent fixtures placed a few inches above them for 12-14 hours each day.

Transplant the little, grass-like seedlings outdoors as soon as garden soil is dry enough to work thoroughly and daytime temperatures reach 50° F. Onion transplants will tolerate light frosts. Planting as early as possible is important because more leaf growth equals bigger bulbs. Each leaf will develop one layer in the onion bulb and the more layers, the bigger the bulb at harvest.

Place the seedlings 4 inches apart in wide row plantings. When using “wide” rows plants are not placed single file on one long row, but spaced through a row ranging from 6 to 36 inches across. Use a row width that is convenient for you to reach fro both sides, to make harvesting and weed control easier.

Growing Onions from Sets, Transplants or Seeds

When should I plant seeds to start vegetable garden transplants indoors?

Tomatoes normally take about 6-weeks to grow into a good-sized transplant. Peppers require about the same amount of time, but slower growing cultivars may require 8-weeks. The correct indoor sowing dates for several popular flowers and vegetables are:

  • early March - cabbage, broccoli, and cauliflower;
  • mid-March - pepper, eggplant, petunia, and salvia;
  • late March - tomato, marigold, and zinnia;
  • late April - muskmelon, watermelon, squash, and cucumber.

If unsure of the sowing date, check the seed packet.

Can dormant seeding of a lawn be done in winter?

Yes, ideally dormant lawn seeding is done from mid-December through mid-February, after soil temperatures have dropped below 40° degrees F. Seeding should be done no later than March 15th. 

Dormant seeding has several benefits. First, soil preparation can be done at your leisure during dry fall conditions. There’s no rush to get the work done in a short window of time in spring between frozen soil and wet soil. Dormant seeded turf grows well and fills in during cool spring weather, preventing much of the potential invasion by weeds. Finally, plants have more time to develop vigor and a good root system before hot summer conditions arrive, making them more able to tolerate summer stresses.
