New discoveries still being made after 250 years
New plants discovered or described by botanists from the Royal Botanic Gardens, Kew in its 250th year include Madagascan relatives of the coffee plant, a South African yam with a reputation as a cancer cure, and two eucalypts from Australia that have potential as ornamentals. Read more at the Kew website: Kew botanists discover over 250 new plant species in Kew's 250th year (December 2009)

The growing business grows in Qld
A survey commissioned by the Department of Employment, Economic Development and Innovation indicates that inspite of drought and water restrictions, the lifestyle horticulture industry has grown "significantly" in the last ten years. The outlook for 2010 is optimistic. Source: A blooming great gift idea (December 2009)

Springfield Central Parklands - first stage open
Stage one of "the most significant parkland in south east Queensland for a generation" has been officially opened. Completed portion includes cycling and pedestrian paths, landscaped gardens. It forms part of Robelle Domain, a recreational hub that will contain an piazza, education centre, cultural displays, restaurants, picnic areas and playgrounds, complemented by lakes and water features. More from Ipswich City Council here: Springfield Central Parklands takes shape (December 2009)

Native orchid rediscovered
Two plants of Dwarf Spider-Orchid (Caladenia pumila), have been found in Victoria. This species was last seen in 1926, and was thought to be extinct. In the two months since the discovery, no additional plants have been found. The location of the two known plants is being kept a secret for their protection, but attempts are being made to propagate from them. More information from Victoria's The Department of Sustainability and Environment: ‘Lost’ orchid re-discovered after 83 years (December 2009)

When is a plant "carnivorous"?
UK scientists are exploring notions of what consitutues a carnivorous plant in a review paper Murderous plants: Victorian Gothic, Darwin and modern insights into vegetable carnivory. Common plants that can trap insects in sticky hairs, for example, may benefit from the nutrients released when the insects eventually break down. These might be considered partly carnivorous. Read more at the Royal Botanic Gardens, Kew website: Scientists think 'Killer Petunias' should join the rank of carnivorous plants (December 2009)

Tall coconut palms present problems
A number of tall cocunut palms are to be removed from Bangara in the interests of public safety. Besides the danger of falling nuts, trees over 20m require a crane for maintenance, which is particularly dangerous when working with with flexible, swaying palm trunks. As the palms grow old, they're also prone to rotting and breakage. Source: Dangerous coconut palms to be removed (November 2009)

Australians return from space mission
The Australian native plant seeds that were launched into space last year have returned to Earth. While Wollemi Pine germination tests are still underway, the Golden Wattle, Flannel Flower and Waratah seeds have germinated normally. They appear to have survived six months of microgravity and low-level ionising radiation in the International Space Station without damage, but will continue to be monitored and tested. The ability to withstand such conditions will be important if plants are to be cultivated in space greenhouses in the future, or perhaps on other planets.

Greening the leaders
You've probably heard about the Whitehouse vegetable garden by now, but the movement to make green examples of other official residences is spreading. Green the Grounds.org are calling on state governors to establish veggie patches and introduce more sustainable gardening practices into management of the landscapes surrounding their mansions. Influential garden blog Garden Rant often reports on this topic (as well as other U.S. garden trends). Meanwhile, the grounds of Buckingham Palace are once again growing vegetables. Read about it at The Guardian website: Queen turns corner of palace backyard into an allotment

Big Tree Database for Australia
Ever wondered how big the largest specimen of a tree species is, or where it's located? A National Register of Big Trees is now being established to collect such information for Australia. Members of the public will be able to nominate native or exotic trees of significance in parks and gardens as well as natural habitats. Learn more at the website: National Register of Big Trees

Snakes in the garden
Moreton Bay Regional Council advise residents to keep their gardens tidy to reduce the risk of snakes. This includes picking up fallen fruit that might attract rats or mice. Old branches and other rubbish can also provide a home for small animals that are in turn a food source for snakes. See: Residents urged to exercise snake safety (May 2009)

Water tanks implicated in dengue threat
A recently published paper suggests that climate change won't directly increase the risk of dengue fever, because conditions are already suitable for transmission of the disease. It's the proliferation of domestic rainwater tanks that could lead to its spread by providing breeding grounds for the mosquito vector. An EScience News report here: Humans, not climate, driving increased dengue risk in Australia. Original paper here: Australia's Dengue Risk Driven by Human Adaptation to Climate Change (PLoS Neglected Tropical Diseases). (May 2009)

More veggie gardens in Washington DC
Hot on the heels of establishment of the White House vegetable garden comes declaration of the entire grounds of the United State Department of Agriculture (USDA) headquarters as "The People's Garden". (Agriculture Secretary Vilsack expands "The People's Garden" to promote healthy food, people and communities across the nation) A sustainable landscape is planned illustrating ways the UDSA contibutes to food production around the world and demonstrating ways the public can implement sustainable gardening concepts at their own homes, businesses and farms. A highlight is the Three Sisters Garden, based on the traditional American Indian garden techinique of interplanting corn, squash and beans. More information at USDA People's Garden Initiative

Cornubia Forest Park expanding
43 hectares of high biodiversity bushland in Cornubia has been jointly purchased by the Federal Government and the Logan City Council and will be added to Cornubia Forest Park.

Overseen by the coucil in collaboration with local groups/volunteers, information and workshops will also be provided to educate the public, especiallly children. The produce will be available to the public for free. Source: City parks bear fruit (April 2009)

Gold Coast water tank inspections
Beginning 27th April, a six month program of door-to-door inspections of homes the Gold Coast City Council knows to have tanks will commence, "to help keep owners up to date on how to maintain their tank systems to protect their own health and safety." A public education campaign on the topic will also be conducted during this time. More at the GCCC website here: 'Checkup' program to help keep rainwater tanks healthy. (April 2009)

Gardens of of the future?
Husqvarna (which manufactures outdoor power tools) has released results of a survey conducted with people from eight northern hemisphere countries to gain insight into current and future gardening trends. A summary of U.S. trends is provided here: New Trend Forecast Reveals Evolution of Lawn Care in the 21st Century. (April 2009)

Powerline unfriendly trees to be removed
Some trees on the Redcliffe peninsula presenting safety and maintenance problems will be removed by Energex. Where possible, they will be replaced by more appropriate alternatives. Source: Energex to replace problem trees (PDF) (April 2009).

Add value with landscaping?
More evidence that landscaping is a good investment - a study of homes in Lubbock, Texas, indicates that quality landscapes can have a substantial effect on sale price. Reported by Jeff Gillman here: New Hort Research that Gardeners Can Use - March '09 Roundup. (UPDATE: a copy of the original article is now available in PDF form from the American Nursery & Landscape Association here: Impact of Improved Landscape Quality and Tree Cover on the Price of Single Family Homes)
On the other hand, a 2008 UK study indicated that in a falling property market, most home improvements (including landscaping) don't recover the money spent on them. See House Prices: Home improvements are a waste of money (Telegraph Media Group) and Home improvements 'not recommended' MSN Money (UK)

In the garden in January

The following applies to the greater Brisbane region. It's hoped to develop these notes further in future updates, in addition to adding guides for other parts of Qld. Naturally, this is a general guide only and will vary depending on local conditions, weather, plant variety etc.

Happy 2010, everybody.

December brought the South East substantial rain, at last. Apply a complete fertiliser, or fertiliser formulated for your the type of plant you wish to fertilise, if available. With growth stimulated by the water and warmth, demand for nutrients will be high and deficiencies are likely especially after the heavy rainfall has leached minerals from the soil. (note however, that waterlogging can also induce deficiency symptoms by interfering with the activity of roots, so pay attention to drainage if you suspect this problem).

If you haven't mulched in a while, top up garden beds without delay to preserve soil moisture and supress germinating weeds. You should avoid walking over garden soil to minimise compaction, but this be particularly avoided while the soils are saturated. Likewise, avoid driving over sodden lawns. This is a good time, however, to manually remove localised weed infestations. Whether hand weeding or spraying, get to work before they set seed. Unfortunately, it is too late to do anything about bindii, except extract the prickles from the soles of your feet. Learn to recognise the foliage and be on the lookout next winter/early spring and attack the developing plants then.

When the sun comes out, take note of where you'd like more shade and try to determine the optimal location and height of shade structures or trees at the time of day you need it. You might like more shade over the entertaining area in the late afternnon, for example. The movement of the sun is different in winter, and you can't use it's position in winter to position shade for summer (you may like to preserve access to sun in winter, on the other hand). While potted trees and shrubs can be planted at any time in SEQld, you'll probably prefer to wait until it's a little cooler. this will mean less stress for both the gardener and the plant. Needless to say, when positioning treees, you also need to take other factors into account such as proximity to buildings, utilities etc.

With the general landscape looking green and lush, the pressure will be off watering gardens for a while, but don't forget about your potted plants. They will dry out quickly in hot weather and require regular watering. Don't be fooled into thinking a shower of rain will do the job for you, because very little, if any, will reach the potting mix of a well-foliaged plant.

If we continue to get drenching rains, on the other hand, constantly full pot saucers can cause waterlogging and rotting of potted plants as well as provide breeding grounds for mosquitoes. Empty these or remove them completely while the rain lasts. Check the garden for other receptacles that could harbour mossies, too.

Weather conditions are too harsh and pests and diseases too active in January to do much vegetable planting, but the main autumn planting season isn't that far away. Start planning what you'd like to grow this year, and get your order in to a mail-order seed companies if you want to try unusual or hertiage varieties not available throught the chain stores.

If you want to try some veggies, consider sweet corn, heat-tolerant lettuce, radish, cucumber, cherry tomatoes, silverbeet. Otherwise, wait until milder temperatures arrive, when a larger range of vegetables becomes more feasible.

Two vegetables that need to be started early, however, are cauliflower and brocoli. These winter vegetables need a long growing season so have to be started in summer. Be sure to protect them not only from the hot sun, but also from the voracious cabbage butterfly, which will still be very active during the warm months.

Be vigilant collecting fruit-fly infested fruit off the ground, to prevent the grubs pupating into a new generation of flies.
Give poinsettias and snowflakes a final light pruning to encourage more bushiness prior to the initiation of flowers as the days shorten.
