The first commercial activity on the farm would of been potatoes. William Coburn planted 30 acres annually during the 1870's. Before this the farm activity would of been substance agriculture. Surplus products would of been sold or bartered at the Fredericton market on Saturdays.

In 1875 the first commercial apple orchard was planted by William Coburn. Fred Coburn planted their first apple orchard around the turn of the century. Apple orchards were expanded over the years until they totaled 100 acres. Apples were a main stay until 1998 when we went out of the commercial production. Today there is 10 acres of apple production left on the farm. The orchard is managed as a processing orchard. All of the apples are processed into apple cider.

In the 1920's both farms got into farm production. Foxes were raied for their pelts. This activity lasted until the late 1930's.

Dairy production on the commercial scale started in the early 1900's on both farm. William Henry and Burris Coburn had a herd of 25-30 milking cows. They started off with grade cows and slowly built up the herd with purebred animals.They were involved with milk production until the mid 1950's when they went out of dairy to concentrate on expanding the poulty production.

Fred and Donald Coburn were also involved with dairy production. They also ran a grade herd milking 25-30 animals. In 1948 the Sloat farm was purchased to expand both the dairy and apple production. In 1968 Donald expanded the barn on the Sloat farm and the milking herd was moved there. He was milking approximately 60 cows at his peak production. Donald sold the dairy farm in 1983 when he retired from active farming.

Bee production was started by William Henry Coburn in the 1920's. The bees were used to pollinate the apples and for honey production. He managed about 20 colonies of bees for about 20 years.

Apple cider production was carried out in every generation but it was John Coburn who took it to the commercial scale. in 1988 he purchased the cider press from another producer. Over the next 10 years he built up the business developing marketws around the maritime provinces. Today we press around 50,000 liters per year.

Poultry production was practiced on both farms. Florence Jean Coburn brought one of the first incubators to Keswick Ridge in 1928. She could set 60 eggs at a time. In the 1930's they had almost 1000 birds. This was expaned over the years until they had 2000 birds in the early 1960's. In 1967 Burris Coburn built a 10,000 bird deep pit cage laying facility. This was followed in 1970 with a 20,000 bird cage laying barn. All eggs were graded on the farm until 1975 when Sunny Glen Eggs, an egg grading stationg, was built by Burris Coburn, Donnie Clark and Dow Goodine.

In 1986 David Coburn built a new 25,000 bird deep pit cage laying barn to replace the older two barns. In 1989 this barn was computerized with full environmental control. This was the first barn in Canada to be fully compertized.

In 1979 Coburn's Garden Patch was opened. This fulfilled a life long dream of Burris Coburn to have a roadside direct market. The farm market was expanded several times over the years to include produce, bakery, garden centre, ice cream and a year round Christmas centre. Vesey seeds was a key part of the garden centre. The Garden Patched was managed by George Coburn and involved the whole family. The Garden Patch was open for 20 years serving the public. It was closed in 1999 when the highway changed.

Vegetable production started on the farm in 1979 growing produce for the Garden Patch. At the peak there was 20 acres of mixed vegetables grown on the farm. The vegetable production was phased out in the late 1980's. It was cheaper to buy produce than to grow it.

With the start of vegetable production a greenhouse was needed to start vegetable transplants. The greenhouses were expaned over the early 1980's to 14,000 square feet of growing space. Vegetable and annual flowers were produced to sell at the Garden Patch. The farm produced 1200 flats of bedding plants until the late 1900's. The ice storm of 1998 collapsed all three of the bedding plant houses.

In 1983 David Coburn started planting vegetables in cold frame greenhouses. In 1985 two more cold frame houses were constructed. This brought production up to 7200 square feet. In 1988 red peppers were produced in this area. By 1993 production had evolved into organic greenhouse peppers. Peppers of every color were produced, This production continued until 2005 when 2 different wind storms destroyed the houses.

In 1993 David Coburn built the first in-vessel composting system in Atlantic Canada. All farm organic waste is composted and either utilized on the farm or sold. Natural Gold compost is sold in bulk and in bags around New Brunswick.
