Branching Out: Farmers Embrace Alternative Orcharding

The time is ripe to take a new look at orcharding design and function. Around the country, from Michigan’s cherry trees to New York State’s apple and peach crops, orchards have been hit with crop losses after late frosts during the past few seasons. Disease pressures, such as those impacting the Florida citrus industry, are another major concern. In circumstances such as these, growers who aren’t diversi­fied may have lost their primary in­come for the year.

Seaberry (sea-buckthorn) is one of many crops grown at Hilltop Community Farm.

The sustainability of a system de­pendent upon one cash crop, along with the lack of diversity inherent in such systems, combined with increas­ing concerns about the amount of chemicals used in conventional fruit and nut production, has led a new wave of orchardists to explore alterna­tive methods of growing fruit.

Forward-thinking growers are uti­lizing a variety of means to reinvent the way an orchard grows. They are cultivating rare, unusual or native fruits, growing in a scale-appropriate manner and addressing orchard di­versity through polyculture and mim­icking natural ecosystems. Continue Reading →

Regional Crops: Preserving Diversity

Regional crops that fed our ancestors and provided a sense of place are disappearing, but some growers and researchers are dedicated to the continuation of these old favorites, refusing to allow them — and our food roots — to disappear.

Jenny Caleo performs a pollination experiment on beach plums.

Whether indigenous or introduced, wild-harvested or cultivated, these food crops at one time held great importance in their various localities. Interest in less commonly known specialty crops is increasing, even while their growing popularity is sometimes accompanied by controversy.

This article will examine four of them.

New England Roots

It goes by many names: Cape White turnip, Westport turnip, Eastham turnip. These names — all taken from New England locales — are used in lieu of its official one: the Macomber rutabaga. Traditionally a part of southern New England Thanksgiving celebrations, this rutabaga is a New England notable, although rutabagas — a hybrid between turnips and wild cabbage — are not native to the United States.

“It’s very similar to parsnips,” said Chris Clegg of Four Town Farm in Seekonk, Massachusetts. “It is not nearly as bitter as purple top rutabagas or bland as yellow rutabagas,” and is quite popular in the region. Continue Reading →

Citrus Greening Solutions

One segment of APHIS’ comprehensive agricultural quarantine and inspection program is based out of APHIS’ National Detector Dog Training Center, an 18-acre facility in Georgia. Sniffer dog Zsemir alerts to a young tree in Florida. 

$3.3 billion. That’s what the National Agricultural Statistics Service rates the value of the citrus industry in the United States. Yet danger and some of the industry’s greatest challenges lurk in citrus groves across the country — devastating pests and diseases.

The Department of Homeland Security estimates invasive species annually cause $136 billion in overall lost agricultural revenue in the United States.

The Asian citrus psyllid, which creates a disease-causing bacteria known as Huanglongbing (HLB) or citrus greening, is one of the citrus industry’s most destructive insects. It has infected commercial and residential citrus trees across the country from Florida to Texas to California. The disease clogs an infected tree’s vascular system, preventing fruit from maturing and eventually killing the tree.

First identified in China in 1919, by 1937 it had spread to the Philippines and South Africa. Continue Reading →
