I don't want to use chemicals, but my brassicas are all being eaten at a rate of knots! What should I do?
There is an absolutely wonderful tried and tested product called Caterpillar Killer (Dipel): which is a great biological control and works strictly on caterpillars. Mix and spray on the leaves (both sides) and within a matter of days all those little grubs will have gotten a REALLY bad stomach ache and died off ! This needs to be repeated if it rains. When watering, simply water below the leaves to prevent it washing off. Another helpful hint is to look at the undersides of the leaves often... those tiny yellow bits you may see attached to the leaf, are actually the little caterpillar eggs.. simply wipe them off and no caterpillars will hatch out !
I love my apple trees, and don't want to use chemicals, but each year my apples are riddled with little grubs... what can I do to stop then from ruining my crop?
None of us want to use harsh pesticides that harm beneficial insects or the environment. We always carry a wide range of natural / biological controls as well as safe sprays and physical traps and barriers that will successfully control pesky bugs. We've got terrific Codling Moth lures and houses to place them in, available for your convenience. Or try the recently released Success Ultra which is derived from beneficial soil bacteria ! Come down and chat with us and we can give you all the best advice to help you harvest clean and healthy fruit.
What can I do for Black Spot on Roses?
During the winter months when your roses are dormant, it is a good idea to spray with Lime Sulphur before the new growth starts to appear. Following this, Healthy Earth Plant Spray will help protect your bushes against fungal and insect attacks. It is also very important to keep the leaves of your roses dry overnight, to stop the fungus taking hold - so keep any watering away from the leaves.
We have a great new product for fungal problems called Eco-Fungicide and it will help you keep on top of Black Spot as well as Powdery Mildew and Rust. It is a great contact spray and registered as Australian Organic too.
Why aren't my Hydrangeas blue just like my neighbour’s?
The colour of Hydrangeas is largely influenced by the soil pH.... if you have a very alkaline soil your Hydrangea flowers will tend to be pink... if acid they will be blue. White Hydrangeas are not affected by soil pH however. If you would like to maintain a strong blue colour you will need to use some Hydrangea Blueing Tonic by watering can approx. every 2-3 weeks in winter. This will also help keep your Hydrangeas in a healthy condition. Applying garden lime or dolomite will strengthen the pink colour.
How do I grow plants in my clay soil?
Site preparation is most important before you plant anything ! We recommend Healthy Earth Soil Builder Instant Clay Breaker (twice as strong as gypsum) applied at the rate of 1/2 kg per sq. metre. Planting Compost should also be added to the soil (1 : 3 ratio) and thoroughly dug in with the Soil Builder to a minimum depth of 30 cm. This will ensure your new plants get a great start in life!
I have a new puppy and don't wait to put out snail pellets!
We hear you, and we have lots of customers with the same worry... as well as not wanting to put out pellets because of their children. Multiguard snail pellets are non toxic to animals and children, but if you are still afraid to use these you can try our wonderful product 'Slugga'. Slugga is a roll of copper tape, perfect for pots and containers, preventing a barrier that snails will not cross. Snail traps are also great and work with salty water or beer added to them... all chemical free and easy to use.
How do I prevent leaf curl on my stone fruit?
If we happen to have a wet spring, you can pretty well rest assured that your peach or nectarine trees (either fruit or ornamental) could fall victim to Leaf Curl. This common fungal disease over-winters in crevices in the bark of your tree and around the new emerging buds. The disease will affect the leaves (unsightly blisters) as well as the soft new shoots and even the fruit. We recommend using a preventative Copper spray twice a year... at ‘leaf drop' in Autumn and ‘bud swell’ in Spring. We carry all you need to combat this pesky disease, so do come down to the nursery and we can advise on this problem further.
Can you explain the different types of Paeonies to me?
Herbaceous Paeonies die right back to the ground each winter, going completely dormant, and then produce totally new growth each spring. Tree Paeonies actually have a woody trunk that remains standing all through the year. Tree Paeonies hang onto their leaves through autumn, turning attractive colours before they fall. Itoh Paeonies are hybrids of the first two types - fairly recently on the scene, they offer a stunning range of flower size and colour.
All have stunning flowers. Herbaceous ones are in shades of pinks, including two-tones, as well as lovely cream/white. Tree Paeonies have more colour variety including yellows, plums (nearly black), oranges and apricots. Itoh Paeonies offer a mix of the two. All come in single and double forms.
They each thrive in humus rich, friable, organic soil, and will perform at their best with generous yearly applications of garden lime or dolomite... this really is important! They enjoy a good amount of sun.. but appreciate some shade from the hottest part of the day.
Winter is a great time to plant dormant Paeonies...or choose from the huge range of potted plants in spring. So be sure to drop into the nursery and choose from the BEST selection in Canberra !
When should I feed my roses?
This is probably one of the questions we get asked most often.
As winter draws to a close and the first hint of spring warmth urges us to get out into the garden, our roses are waking up from their winter dormancy too !
Hopefully, all of your established roses would have been pruned in August and are well and truly bursting out with shiny, healthy new growth by now... which means... it's time to start fertilising! Here in the Heritage Nursery, we stock 'Sudden Impact' fertiliser that is specifically formulated for roses and will guarantee strong growth and an abundance of blooms. From spring until autumn, feed every month. We also carry our wonderful tried and true 'Healthy Earth' fertiliser, which you can use alongside your rose fertiliser... alternating between the two. Healthy Earth is a great all around choice for the WHOLE garden (natives plants too) and contains more than 40 minerals, nutrients and trace elements, adding organic matter and encouraging earthworm population in your soil.
Then sit back and get ready for the show...
Do I need to feed my native plants?
Many people assume that once you've planted an Australian native plant, you will never have to lift a finger again and they will magically live forever with zero care.
Not true of course! While in general, native plants are pretty low maintenance, fertilising can boost active growth and general health of the plant. Some natives are sensitive to many fertilisers due to the high Phosphorus levels they contain. Here at the Heritage Nursery we recommend using a specific fertiliser called 'Bush Tucker' OR our wonderful organic 'Healthy Earth' fertiliser which is suitable for all plants.
Remember... as well as fertilising, pruning and drainage are equally important when tending to your Aussie plants. We are here to advise on all your native plant needs whenever you visit the nursery.
