Learn more about growing heirloom apples in this interview with a professional orchardist.
This past Saturday, I attended an heirloom apple tasting at Garden for the Environment in San Francisco. Garden for the Environment is a one-acre urban demonstration garden that offers environmental education programs about organic gardening and sustainable food systems.
The apple tasting featured 18 dessert apples including varieties such as Cox's Orange Pippin, Cherry Cox, Freyberg, Pink Pearl, Arlet, Greensleeves, Fiesta, Chehalis, and Elstar. The tasting was led by Matthew Sutton, a professional orchardist and owner of Orchard Keepers, a company located in Santa Cruz, California that specializes in orchard design, installation and maintenance.
I caught Matthew after the tasting to ask him about growing heirloom apples.
PlanterTomato (PT): Tell me a little about Orchard Keepers and how the company got started?
Matthew Sutton (MS): Orchard Keepers installs, maintains, designs, renovates, and restores backyard and home orchards. By home orchard, I mean anything from just a few trees to 80 trees it really just depends on the size of your backyard. We are moving increasingly into full installations of backyard food forests that include trees and also perennial crop systems such as berries and artichokes and even some vegetable beds. Finally, we are planting native plants to provide habitat for beneficial insects.
I started Orchard Keepers after completing a number of different training programs where I discovered fruit trees. With land prices as high as they are in Santa Cruz, I didn't think I would be starting my own orchard any time soon, so I created this business that lets me work in the tree world immediately.
People in Santa Cruz are interested in growing their own food; they are looking for better tasting food and also are seeking more food security. Orchard Keepers helps them with this.
PT: Who is the typical customer for Orchard Keepers?
MS: For installations, our typical customer is a young family that knows they are going to be feeding a group of kids for years to come. They also want to teach their kids where food comes from. Fruit trees take 3-8 years to produce good crops, so it's a good idea to start when your family is young.
For restorations, I'm hired by people who have owned property for a while but need help putting their trees back into production again. I'm also hired by schools that have gardens that need similar help.
PT: Most consumers are aware of 6 or 8 apple varieties. These are the ones they can buy in a typical grocery store. At Orchard Keepers, you specialize in heirloom apple varieties. What's the difference between an heirloom apple and one I get at the supermarket?
MS: A lot of the varieties you buy in the supermarket these days are bred more for storability and shippability, not flavor. There's nothing like eating an apple straight off the tree, or for that matter any piece of fruit off the tree or cane.
Even some of the more mainstream varieties that you find in the grocery store, if you grow them in the backyard and you're eating them fresh when they are ripe, it's going to be a different eating experience.
That said, if you are open to, and have access to, heritage heirloom varieties, you have almost endless flavor options. If you do your homework and know what flavors you want you can grow varieties you like and harvest them from mid-July through December.
PT: OK, if I have 6 or 8 options in the supermarket, about how many options do I have with heirloom apples?
MS: There are a number of nurseries that are storing and protecting our genetic heritage. (Trees of Antiquity is a good one) At these nurseries, there are at least a few hundred varieties available and at seed saving sites there are probably several thousand.
PT: Let's say I'm a home gardener thinking about putting some apple trees into my garden or possibly into containers, what sorts of things should I take into consideration when choosing a specific variety?
MS: Choosing the right varieties has a lot to do with climate. All fruit trees need a certain number of chill hours. A chill hour is an hour where the temperature is between 32 and 45 degrees Fahrenheit and each type a tree needs a specific number of those hours in the winter time to break out of its dormancy.
In coastal climates, southern California or in the Southern Eastern states, you may not get many chill hours, so you need to be careful to choose a variety that will work in your climate. If not, the tree may not bloom all at ounce (spotty bloom) and you won't get a very good fruit set. The trees also may not grow very well. That can be very discouraging after you've done all the work to planning and planting and then not have the tree respond properly.
It's also important to know what you want in terms of the flavors you prefer.
Finally, its important to know the ripeness dates. Where I live in central California, I can be picking something from the tree or bush every day of the year.
PT: So let's say I decide to take the plunge and put some trees into my backyard, what kind of basic care and maintenance do I need to do?
MS: Growing fruit trees is great because it's not like a lettuce crop where you have to water the plants every day and do constant weeding. With fruit trees you have 4-6 pulses of work during the course of any given year.
Pruning is very important. For good information on pruning, you might want to purchase a book published by the University of California called The Home Orchard. It contains lots of great illustrations and instruction on how to prune. You can also take a class on pruning from your local agricultural extension agency. You'll need to do winter pruning and potentially some summer pruning. Winter pruning has a very stimulating effect on your fruit trees and summer pruning is going to slow down growth.
You will also need to thin fruit. Hopefully, all your trees will set fruit, but you can sometimes get way too much fruit and you'll need to thin it. Each type of fruit has a different thinning requirement; you can find out how much thinning to do in the Home Orchard book I just mentioned.
During the course of the year, you should be aware of any diseases and pests. A lot of times, if you catch things like aphids and white flies early, you can treat them organically using insecticidal soap or neem oil.
The other tasks you need to do are harvesting and soil care.
Soil care is of the utmost importance. You can do all the training and pruning, but if you don't have biologically active soil, rich in organic matter, the tree won't perform well. An annual application of compost is important and I would also recommend using 4-6 inches of a wood chip mulch, applying this every 2-3 years. This will help conserve moisture and help build soil structure.
When the tree is young, you should apply a high nitrogen organic fertilizer. But once the tree has filled the space you want it to occupy, there's really no need to apply fertilizer, compost will be adequate.
PT: You brought up the issue of space, so I wanted to ask you about containers. Is it possible to grow heirloom apples in pots or containers?
MS: If you can plant in a 1/2 wine barrel container, you can plant a dwarf rootstock apple. All apples are grown on a rootstock. If for example, you wanted to grow a dwarf Fuji apple, you look for a Fuji apple that's grown on an M27 or B9 dwarf rootstock. If you do you research, you'll find the varieties that are on dwarf stock and I recommend that you plant only those varieties in containers. If you try to put a semi-dwarf apple into a container it's not going to work.
PT: Will any scion, or apple variety, work on a dwarf stock?
MS: Yes, once the scion is on the rootstock you're going to get the same variety of apple even if it's a dwarf rootstock.
That said, the relationship between the scion and the rootstock will be different with each variety. If you put a Honey Crisp apple on a dwarf rootstock, it's going to be a super punky tree. The honey crisp scion is a weak grower. But if you had a Jonagold or Chehalis scion on a dwarf rootstock you're going to get a nice tree because both of these apples are strong growers.
PT: What other advice would you give someone putting apples into their home garden?
MS: If you are going to put in several trees, do your research first. If you choose the right varieties, you can extend your harvest season and be able to eat apples from mid-Summer through the Fall.
I would also recommend doing good soil preparation, maybe doing a cover crop the year before, apply the compost the year before, and really just preparing that soil well before you plant.
And when you plant, don't go to the nursery and buy a potted tree. You'll do much better if you buy a bare root tree and planting it in the Winter time.
PT: Matthew, if someone wanted to hire you to help them with their home orchard, how would they contact you?
MS: You can e-mail me at [email protected]. I am also in the process of updating my web site http://www.OrchardKeepers.com and plan to add a lot of the information we discussed today on. The new site should be online after the first of the year.
PT: Thanks for your time and for your advice.
MS: Thank you.
