Best plants for Brisbane’s weather

strawberry-watercolour

I attended a seminar on vegetable gardens presented by Tim Auld. He encouraged the group to brainstrorm the best plants for each of the seasons in Brisbane.

He explained that the traditional seasonal climates (spring, summer, autumn and winter) are mostly applicable to southern states of Australia. Queensland has a more temperate climate (sub-tropic) and further north have a tropical wet season (Dec – March).

Here’s the list of plants the group came up with:

Plants for the wet season (December to March):

  • ceylon spinach, choko, kang kong, melons, squash,  snake beans, sweet potato, taro and yams

Plants for a Cool temperate summer (April to August):

  • broccoli, carrot, garlic, lettuce, onions, peas, potatoes, radish, silverbeet, spinach, and tomatoes

Plants for a Mediterranean summer (September to November):

  •  basil, beans, beetroot, capsicum, chilli, corn, melons, silverbeet, and squash

Getting started growing Bananas in Queensland

bananas3-new

Here is some of the information I discovered while researching how to go about growing bananas in your backyard for Brisbane and Queensland.

Bananas require full sunlight for most of the day. They do best is a sheltered area where the roots will not become flooded. The best time to plant them is from September to mid-December.

Bananas require generous amounts of plant nutrients to grow and fruit. (800 grams of lime, 240 gram of urea, 30 grams of super)

Residential growers in south Queensland require a permit to grow a maximum of 10 plants. Permits are free of charge and made to Biosecurity (currently part of the Department of Agriculture and Fisheries).

Permitted Bananas in Queensland

The only permitted varieties of bananas are:

  • Blue Java – Silvery wax bloom, white flesh, dessert and cooking
  • Bluggoe (plantain or cooking banana) – angular fruit
  • Kluai Namwa Khom (Dwarf Ducasse) – fragrant sweet flavour, dessert and cooking, very vigorous. Referred to as sugar banana.
  • Goldfinger – tangy tasting, doesn’t turn brown when cut
  • Ladyfinger – drought hardy, long shelf life, dessert type, sweet creamy flesh
  • Pissang Ceylan -pinkish midribs on leaves, agreeably sweet acid

There is currently ONE supplier in Queensland – Blue Sky Backyard Bananas – each plant costs from $25 including postage and handling.

Further Information

Agrilink have developed a Tropical banana information kit as a series of PDFs. The kit provides information on all aspects of growing tropical bananas in Queensland.

Jerry Coleby-Williams has written a great Fact Sheet: Growing Bananas for the ABC Gardening website.

Tree planting and watering

Here are a few more steps to assist keeping your trees hydrated:

Add a handful of water crystals to help the plant survive in drought and periods when you neglect to water them. The clear jelly-like crystals absorb and store water.

Plastic aqua spikes or water cones are pushed into the root zone of a seedling or plant to give it a regular watering. A plastic water bottle is added on the other end. You can also add kelp and fish fertilizer to the water to fertilise at the same time.

The local council uses pipes with their road side plantings. These pipes are usually 30 cm long with perforated holes. They need to be inserted into the ground before the seedling or tree is planted in place, and allow water to be directed at the root zones of the plant. This targeted watering prevents water loss from evaporation and is more efficient then watering at ground level.

Tree guards are triangle plastic sleeves that held in place by a three wooden stakes. Other versions are made from pink coreflute plastic. They help increase the success rate of seedling plantings by reducing cold, wind and animal damage. They are used by Landcare in Australia for bush regeneration projects and highway plantings. A smarter version includes a water pouch to provide self-watering to the root zone.

Homegrown Evolution has a great list of self-watering planters.
