How to grow blackberries in Perth, WA:
The first thing to do before planting blackberries is to clear away weeds because their competition will really slow the growth of the blackberries.  Blackberries also tend to take over other plants as they spread so it’s important to keep this in mind when selection a location to plant blackberries at home.

  1. Improve the soil prior to planting blackberries by mixing in some soil Improver and plant fertiliser. Good soil health and structure helps the soil hold onto moisture and nutrients; and improves plant health and berry growth.
  2. Set out the dormant canes 1.5m apart, in rows 2m apart if you are planting a few plants.
  3. Canes can be tied together loosely with twine. If using a trellis or a structure for blackberries to grow on, make sure this is in place at planting time.
  4. After planting blackberries, water them in well. Keep soil moist and water as required.
  5. Blackberries continue to bear for many years. Pick fruit when ripe and well coloured.
  6. Feed with citrus plant food in early spring and late summer.
  7. During flowering and fruiting season feed with a strawberry and berry liquid plant food weekly.

When to harvest blackberries:
Blackberries are typically ready to harvest in summer between December through March depending on the variety and which part of Western Australia you live.

Storing blackberries at home:
Blackberries should be kept in some kind of vented container – either keep a berry container from a supermarket purchase of blueberry or blackberries, or if you are going to use ongoing I recommend investing in a reusable container like the Rubbermaid Fresh Works Produce Savers (my favourite). Venting is important for air flow – blackberries produce ethylene, a plant hormone that tells fruits and vegetables to ripen. If blackberries are in a completely sealed container, they will go bad faster. If the container is vented on the other hand, the ethylene gas can escape and your berries will stay fresh for close to a week.

Blackberries care and common problems:
There are few problems in the Perth area, but scale insects on the stems may need to be controlled. Black spots on the leaves may be controlled with mancozeb.

Blackberries should be planted in rows running north to south so the canes receive ideal sunshine.  Cover the blackberry bush with shade-cloth to protect the fruit from the sun.

  1. Unbelievable!!! I have read the WA government’s website where it says that blackberry declared as pests!!!!
    Everything that is good ans healthy for you is declared bad for you because there’s no money in for the government 🤯🤯🤯
    I was wondering if I can eat the blackberries growing along the coast.
    So, there all edible? is that correct?

  2. My berry bush is dying, I got it in a pot it is under shade cloth so that full sun does not burn it . we planted it last winter . I keep it moist but not wet
    When planted we put potting mix initially it developed beautiful leaves than started to get brownish edging around the leaves and the main branch has died only the leaves are left right near the roots.
    obviously I am doing something wrong to stress the plant but I don’t know what. have you got any ideas?
