Learn more about the many fruits of Toronto's Urban Orchard


Plums of many varieties, colours and flavours can be found in Toronto’s urban orchard. Plum trees are not very abundant so these local edibles are quite a rare treat. Plum tree produce round or oval-shaped fruit, around the size of a golf ball with a central pit. Depending on the variety, plums can be purple, blue, green, yellow and/or red when fully ripe.

How to tell when plums are ripe: When the skin has changed colour, the flesh is soft, and the fruit pulls easily from the branch with just a light tug. Many varieties will have a ‘bloom’ of white powdery substance on ripe plums. This powdery stuff is a harmless fungus that needs a specific sugar content to survive and is only present in ripe fruit. Plums will ripen off the tree so they can be harvested when a little underripe.

When to submit a pick request: We’ll need some advance notice to schedule your pick, so please submit a fruit pick request 3-5 days before your fruit is ready. A good time to do this is when most plums on the tree have just lost their greenish hue (unless you have a green variety) and yield to pressure when gently squeezed.

Picking tips: Pick by hand with a slight twist or with picking poles and leave stem attached. Ripe plums may drop easily from the branches so it’s a good idea to use a drop sheet or tarp to catch excess fruit.

Storage tips: Plums will continue to ripen off the tree. Place ripe fruit in the fridge right away, and let unripe fruit ripen on the counter or in a paper bag. Be careful to check on ripening plums — they can go quickly from unripe to overripe.
