This is a good time to take the opportunity to review the condition of all tools used to make these cuts and apply the appropriate response.
How to Start an Orchard
An orchard is a wonderful asset for any farm. Whether grown for the family homestead or to sell fruit, orchards provide a variety of benefits big and small.
At the Maine Organic Farmers and Gardeners Association (MOFGA) campus in Unity, nearly 2 acres of the Common Ground Country Fair’s permanent site is an experimental orchard. Another quarter acre or so is a tree nursery. Both sites act as test plots for soil amendments, cover crops, rootstocks, and trialing new and old fruit cultivars.
MOFGA is also home to the Maine Heritage Orchard, a 10-acre educational preservation orchard. The orchard is already home to over 300 varieties of apples, plus some pears, traditionally grown in Maine — and more are being added each year. The Maine Heritage Orchard collection includes varieties from all 16 counties in Maine, dating back as far as 1630. Until recently, many of them had been on the verge of extinction.
Whether you want to plant two trees or two thousand(!), here’s a guide on how start an orchard. Read on to find out where, when and how to plant an orchard, and how to care for it in the long term.
What is an orchard?
Simply put, an orchard is land planted with fruit trees. An orchard can be a source of food for families or a business enterprise for farmers. Orchards, like MOFGA’s Maine Heritage Orchard, can also help preserve the genetic diversity of fruit crops.
When people think of orchards, many think of apple orchards. The hardy trees can withstand cold Maine winters and there are many varieties to choose from — so many that MOFGA even has a day dedicated just to celebrating and tasting apples! An apple orchard may also include crabapples, with fruit that can range from dessert-eating quality to those better left for the birds to enjoy.
In Maine, you can also easily grow pears. With some finesse, cherry trees (sour, sweet or nanking) and peach trees will also bear fruit in Maine. Orchards can also include non-tree fruits, such as elderberries, aronia and highbush blueberries.
Starting an orchard
Now that we know what an orchard is, let’s get into the basics of starting your own orchard.
The main thing to keep in mind is that starting an orchard takes time. Depending on what you plant, your orchard won’t produce fruit for the first or even second year, but patience will reap sweet rewards.
What you need
The basic requirements for planting an orchard are land, sun and water. However, you will also want to consider soil-building practices, pest control and long-term care for your orchard.
Tools and supplies
Depending on the scale of your orchard, you may need different tools for planting and maintenance. The University of Vermont has a great resource page on all the tools you’ll need. They cover all the necessary things you’ll need from start to finish for growing an orchard.
Another thing to keep in mind is pest and disease control throughout the season. Using homemade solutions for monitoring pests is a great way to see if pest pressures are reaching a threshold at which they’ll become a problem. Pest prevention for specific threats to apples, from roundheaded apple borers to apple sawfly, are detailed here.
Unless you are buying land, choosing your site is limited by the property that you already own or manage. The best sites for fruit crops have well-drained, deep, fertile soils, with full sun and protection from wind. A site with a gentle slope that gets six to eight hours of full sun per day is ideal. Good air flow moderates fungal diseases. Choose the site on your land that encompasses as many of these features as possible. For an example of planting an orchard in a previously wooded space, check out how Deer Isle Hostel planted their “unfettered orchard.”
Avoid the temptation to plant less-hardy varieties, especially early bloomers, on sunny south- or west-facing slopes. These sites tend to warm up before the danger of frost has passed. Trees may flower early, then suffer frost damage resulting in diminished yields or even a complete loss of that year’s fruit crop.
When planning your orchard, keep in mind that a standard apple tree needs 30 feet, a semi-dwarf needs 15 feet and a dwarf needs 10 feet of space per tree.
Choosing a tree
Most fruit trees do not grow true-to-type from seed. Instead, most trees sold are grafted: A small piece of a known cultivar, called scionwood, is grafted onto rootstock. The fruit type is determined by what is grafted onto the rootstock, while the rootstock determines the size of the tree and how and when it will bear fruit. A mature tree on standard rootstock can reach 25 feet or more and bears fruit in about five years under ideal conditions. A semi-dwarf will grow to 70 to 80% of the size of a standard, bearing in three to four years, and a dwarf will grow 6 to 8 feet and bear in two to three years.
Rootstock and varietal selection
Rootstock also affects the lifespan of your apple tree. A standard tree will live over 100 years. The old trees that we pick now are all standard trees. A semi-dwarf tree will live about 10 to 15 years; a dwarf will live about 10 years. Dwarf trees usually need a trellis or support system. Many dwarf and semi-dwarf root systems are sensitive to cold, wet soils and drought. But some roots anchor better than others. You can learn more about rootstock and grafting here.
There are hundreds of apple varieties to choose from. The Maine Heritage Orchard’s searchable database is great reference for apples that are known to produce well in Maine. You can look up apples by name to learn more about their origin, uses (from cider to livestock feed to molasses), distinctive features and look-alikes. You can also sort the accessions by those same parameters to help identify an apple that is, say, blocky with red skin and a russet cavity or yellow with prominent dots. Another useful feature is the ability to sort by season — so you can choose varieties that will fruit at different times.
Planting your tree
Dig a large hole at least twice as wide and 6 inches deeper than the tree’s root system. A larger hole is more beneficial. Next, mix a quart of rock phosphate, azomite, and a few shovels of compost with the soil. Try to plant on an overcast day or late in the afternoon. Soak the tree in a bucket of water for a few hours before planting and don’t let it dry out while planting. Nestle your tree into the hole so that it will grow at the same height it was in the nursery.
Spread the roots in the hole, but don’t let them wrap around the hole. Then, refill the hole, making sure no air pockets form around the roots by gently tamping the soil. Build a bowl or rim at the top of your hole that will hold water and then thoroughly soak the soil. Apply at least 1 inch of water per week – via rain or irrigation – during the entire first year. Lastly, mulch with wood chips.
Keeping good records
Keep good records. Label your tree with the varietal name on a metal tag; the plastic nursery tags that often come with trees are temporary. Write the names in a book. Make a map in a place that you won’t lose it — perhaps painted on the inside wall of an adjacent barn.
Maintaining your orchard
So you have an established orchard. Great! However, there’s so much more to explore, like making sure your orchard is ready for all seasons. Here’s a handy calendar for orchard activity throughout the year.
Mulching and fertilizing
Mulch is material laid on the ground in order to shade out weeds and conserve moisture. Mulches may be either organic or inorganic. Organic mulches are especially desirable, because they can be turned under in the fall or following spring and will add organic matter to the soil. Organic mulches are best applied after the soil has become warm and shortly after a heavy rain. Straw, old hay (watch for weed seeds!), grass clippings, leaves, wood chips, newspaper and sawdust are common organic mulches. Fruit trees do well with wood chips because these help cultivate beneficial microorganisms.
Cultivate before piling on the mulch, and pile it on thick (3 to 6 inches for hay, for example; or six sheets of newspaper covered with a few inches of hay to hold it down) to prevent the weeds from growing through.
Fertilizing is a more complex matter. Each tree requires different nutrients depending on the soil type and the type of fruit. You can read up on each individual fruits’ needs above in the “What is an orchard?” section. You may also consider planting dynamic accumulators, such as comfrey, stinging nettle or red clover, in your orchard ecosystem. Tap-rooted plants absorb nutrients from deeper layers of the soil profile, as they die and decompose, their plant matter and nutrients become available to other plants in the orchard.
Cutting back branches on your trees, or pruning them, determines the shape of the tree, while promoting healthy growth. Basic tools for pruning include loppers, a hand saw, a pole pruner and a ladder. When pruning, cut each branch down to the collar branch, or where the branch meets the tree trunk. Make sure not to cut the collar when doing this, though. The collar protects the trunk from diseases and pests. But make sure not to make too shallow a cut and leave a stub instead — the stump will die and create other problems. Instead, make two cuts to the branch: one that cuts a majority of the branch off to prevent it from snapping, and another to cut the stub from the tree. This skill is best learned by doing — check out MOFGA’s event calendar for workshop opportunities.
Preparing for the season ahead should be done 2-3 months out. One of the most important aspects of your orchard is to ready it for winter. Autumn is a great time in the orchard because you get to share the harvest with your family and community. Autumn is also a great time to clean up the orchard, prepare trees for winter and start thinking about next year’s bloom. If you don’t think ahead and prepare for the colder winter months, you run the risk of winter injury in your trees and fruit.
