Last Frost Date: When To Plant A Garden In Westwood + Hillsdale

WESTWOOD-HILLSDALE, NJ — Inflation, the rising cost of food and the nutritional benefits of homegrown produce have cultivated a new crop of home gardeners in Westwood and Hillsdale.

Whether you’re a first-time or experienced gardener, one of the most important dates you need to know as you think about your garden this spring is:

When does the danger of frost pass in Westwood and Hillsdale? It’s Sunday, April 10, according to The Old Farmer’s Almanac, which offers a ZIP code tool to help gardeners figure out when to plant what.

The growing season is 201 days long in Westwood and Hillsdale. Looking ahead to fall, the first frost usually occurs around Oct. 29.

According to the publication, there’s a 30 percent probability of a frost occurring after April 10, as the date is determined using National Oceanic and Atmospheric historical data from 1981-2010, and is not “set in stone,” The Old Farmer’s Almanac said.

April 10 represents the average date of the final “light freeze,” which occurs when the temperature dips between 29 and 32 degrees Fahrenheit. At that temperature, tender plants can be killed.

A “moderate freeze,” between 25 and 28 degrees, is destructive to most plants; and a “severe freeze,” at anything under 24 degrees, can do heavy damage to most garden plants, according to the almanac.

As the pandemic’s third gardening season gets underway in Westwood and Hillsdale, The Old Farmer's Almanac has another tool to help gardeners decide when to plant which crops.

In Westwood and Hillsdale, it’s usually best to start planting corn from April 10-24, potatoes from April 3-24 and spinach from February 26-March 20.

Here’s a look at other crops, and when the Old Farmer’s Almanac says to begin planting them in Westwood and Hillsdale.

• Beets: March 27-April 17
• Carrots: March 5-20
• Green beans: April 17-May 8
• Okra: April 24-May 8
• Onions: March 12-April 3
• Peas: February 26-March 20
• Spinach: February 26-March 20
• Turnips: March 12-April 3

Even before the pandemic, mental health experts pointed to gardening as a way to deal with stress.

Gardening provides physical exercise and promotes healthier eating, but it can also reduce worry among people who consider themselves perfectionists, psychologist Seth Gillihan said.

“Given the lack of control we have, gardening can be a good antidote for perfectionism,” Gillihan wrote in a 2019 Psychology Today blog. “No matter how carefully you plan and execute your garden, there are countless factors you can't predict — invasions by bugs, inclement weather, hungry rodents.”

With so many things out of their control, perfectionism is a waste of time, he said, so gardeners may ask themselves “why bother” trying to be perfect.
