This is a very common question in the fruit growing world. The answer is very simple—yes (they’re called seedlings)—but in fact the more interesting question is, will a seedling apple tree bear edible fruit?
This is much harder to answer—it’s “maybe”—and in fact depends on sheer chance. The seeds inside an apple are a genetic mix of its parents (just like people), and so the fruit they grow will be a random genetic mixture of the tree it grew on and whichever other apple tree pollinised it. Just like children in a family may be completely different from each other, so every seedling apple tree from that union will vary.
This is important to understand if you’ve moved into a house with existing fruit trees and you don’t know their history, particularly if some of the trees produce no fruit, or fruit that’s not very nice, which is a situation that arises frequently for our Grow Great Fruit members.
There’s a very good chance that the original homeowner (or whoever planted the tree) will not have kept good records or labels to pass onto a new resident.
So, you’ll probably need to do some garden detective work to figure out what you’ve got, and the first thing to figure out is whether the tree is grafted (i.e. a known variety), or a random seedling that has come up. Not sure of the difference?
Here’s a couple of tips that might help:
- Look for a graft union, where the scion was grafted onto the rootstock. Any fruit tree you buy from a nursery will have been grafted (unless you’re buying rootstocks from a specialist rootstock nursery), but unfortunately the graft union may be hard to see in the adult tree. If you can see it (there’s a couple of examples in the photos above and below) – great! You know you’ve got a grafted tree, which means it’s a known variety, and then you can start trying to figure out which one, and look for other reasons why it might not be bearing fruit. If you can’t see a graft union, that’s inconclusive evidence! It may be a seedling, or it may be a grafted tree where the union is no longer visible.
- Another give-away is a tree having multiple trunks. Seedlings are often naturally multi-trunked, while grafted trees always have a single trunk. BUT, it’s very common (particularly if a tree hasn’t been well looked after) to see the original grafted trunk plus a number of suckers from below the graft union that have become extra trunks. One of the ways to spot this is to notice whether seasonal changes (blossom, or leaves changing colour in autumn, for example) look the same and happen at the same time on each trunk, and of course whether they all bear the same type of fruit (or any fruit at all).
Traditionally in Australia (and more generally in the orchard world), seedlings have been thought of only as a source of rootstocks for grafting known varieties onto. Seedlings themselves have been considered at best worthless, and at worst pest trees that must be chopped down and eradicated.
We noticed a much different approach to seedling apple trees when we visited America (and particularly in Maine, which must be the apple-nerd capital of the world), where seedlings are more likely to be appreciated for their own potential:
“A seedling apple is like a musical improvisation In the world of music, one parent would be the original composition and the second would be the musician. When the musician sets aside the printed page and plays the tune extemporaneously, the result is something new….You may or may not recognise the tune. It may be pleasant to the ear, or it may be discordant. Musical improvisations may be endlessly fresh and inventive…they may also be stale, cliche and uninteresting. However, whether you like them or not…each will be new and unique.
Same with apples. Some seedlings will be stale and uninteresting, while others will be quite wonderful. Each is an improvisation.“John Bunker, Apples and the Art of Detection
So, if a seedling tree is potentially a wonderful fruit tree in its own right, why does it matter if your tree is a seedling or a grafted tree? Because (as John points out), “some seedlings will be stale and uninteresting” – or in other words, completely useless, whereas grafted varieties have all been chosen because they’ve been proved to grow apples with desirable characteristics.
And if you’ve got a tree in your garden that has terrible fruit, or very little fruit, you need to rule out (or in) the possibility that the tree is a seedling, and the fruiting pattern is the result of natural variation.
If you’re aiming for fruit self-sufficiency (and if you’ve got room for a few trees, why wouldn’t you be?) then each tree needs to pull its weight by growing the varieties and quantities of fruit you want.
So if you really want to achieve fruit self-sufficiency, you need to know what you’re starting with (as explained in Grow A Year’s Supply of Fruit), because there’s no room in a productive and thriving food production garden for “stale and uninteresting” fruit!
