Garden Tips: This past week we got onions in the ground. Something new I tried, after hearing Kelly Feehan, Extension horticultural educator and Gary Zoubek, Extension educator emeritus recommend it, was to start onions from transplants instead of sets. It’s a tip for growing large onions that store well. Onions are biennials. In year one, they grow leaves and bulb and then set seed in year two. Sets grown for sale removes one season from the growth, so when we plant sets in our gardens, they want to go to seed, so you may see blooming in mid-summer, which limits the onion bulb size. If you do grow onions from sets, look for dime size or smaller sets as they would be less likely to bloom. This year, I’m looking forward to seeing what the transplants do.

Kelly Feehan shares, “Late March through April is typically the time to plant cool season vegetables. These vegetables germinate and grow in cooler soils and can tolerate light frosts. They include onions, potatoes, radish, lettuce, carrots, beets, peas, broccoli, and cabbage.

Potatoes are planted in April, sometimes late March or early May. A tip for increasing potato yields is hilling potatoes after they begin to grow. Once they are 12 to 20 inches tall, carefully scrape soil up around the plant to create a hill. Potato tubers grow on stolons, underground stems, above the roots. Hilling provides more space for tubers to grow and maintains cooler soil temperatures, especially if hills are mulched. As a cool season crop, cooler soil will increase tuber production.

If potato hills are spaced closer together, tubers grow smaller. If hills are spaced farther apart, tubers grow larger. The recommended spacing is 12 inches between hills and 3 feet between rows. The 12-inch spacing will result in smaller tubers. An 18 to 24 inch spacing will result in larger tubers.”

Soil Temperatures can be found at:  https://cropwatch.unl.edu/soiltemperature. This is helpful for knowing when to plant vegetables, when to plant crops, and what the soil temp is when applying fertilizer to fields. It’s also helpful for homeowners to wait to apply crabgrass preventer for lawns until soil temps are at least 50-55F for 5-7 days straight. In spite of the warmer temps, it’s too early for crabgrass preventers (normally we wait for last week of April to early May)!

Lawn Seedings: For those who didn’t seed or overseed turf grass last August-September due to the dry conditions, aim to seed or overseed as soon as possible.
