🎥 Gardeners go home with onions and tomatoes

Manhattan – If gardeners are crying about their onions, it is not because they are chopping in their kitchen. But they may be soon.

“This is a time for onions to grow and develop rapidly,” said Ward Apham, a horticultural expert at Kansas State University. “Regular watering – if the soil is dry – and light fertilizer will help increase growth.”

In alkaline soils, ammonium sulfate (21-0-0) is recommended for use in 10 cups per 10 feet. The numerical combination refers to the amounts of nitrogen, phosphorus, and potassium present in the fertilizer.

“You can use grass fertilizer (like 29-5-5, 27-3-3 or similar) but only use 1/3 cup in 10 feet,” he said. “Make sure there is no weed or weed killer. Sprinkle 2-3 inches of the fertilizer over the row and soak it in water. Do not fertilize after the onion starts to sprout.

According to Ufa, 2/3 of the bulb remains in the soil as the onion grows. He said it was normal and there was no need to cover the bulb with soil.

Tomatoes

Another garden favorite – tomatoes – can be fertilized by fertilizing the soil unless it is warm enough and well watered, Uppam said.

“Tomatoes even prefer soil moisture, and mulch provides protection against excessive evaporation,” he said.

It helps to control weeds, moderate soil temperature and prevent the formation of hard soils. Crushed soil restricts air movement and slows the flow of water.

“Tomatoes are very popular with tomatoes but can contain weeds or volunteer seeds,” said Apham. Grass seeds can be used as a mulch, but they should be applied in a thin layer – “only 2-3 inches thick,” Uppam said.

“Do not use grass clippings treated with weed killers for some time,” he said. “In most types of weed control, cut pieces can be used on the fourth harvest after treatment.”

Apham and colleagues at the K-State Department of Horticulture and Natural Resources provide weekly tips on how to protect the home landscape. The newspaper can be viewed online or received weekly by email.
