The Serenity Prayer
God grant me the serenity to accept the things I cannot change; courage to change the things I can; and wisdom to know the difference. Living one day at a time; Enjoying one moment at a time; Accepting hardships as the pathway to peace; Taking, as He did, this sinful world as it is, not as I would have it; Trusting that He will make all things right if I surrender to His Will; That I may be reasonably happy in this life and supremely happy with Him Forever in the next. Amen. Trust in the LORD with all your heart and lean not on your own understanding; in all your ways acknowledge him, and he will direct your paths. Proverbs 3, 5-6

hen it comes to flowering shrubs, it’s difficult not to be stopped in your tracks by the ravaging beauty of an Azalea in full bloom.
Noel Burdette

5 Most commonly available azaleas look wonderful when used in amongst rockwork, around the edges of ponds in Asian inspired gardens or as potted, feature plantings.
If space is at a prem ium in your garden, then consid er getting the most from your azaleas by growing them in po ts. Searles Camellia and Garde nia Specialty Mix is a perfect choice for all potted azaleas as it is speciďŹ cally desig ned for all acid loving plants. Make sure to choose a glazed pot as your choice as this will reduce moisture loss from the sides and also reduce lime, (w hich is alkaline) from seeping into th e mix over time.

The biggest and m ost common prob lems that azaleas seem to battle are from sa p-sucking insects such as mite s and azalea lace wing. They are easily spotted when the foliage turns from bright green to a mottled, silver pa tterning on the leaves. If left unco ntrolled for severa l years they can certainly wea ken the plant and prevent them from producing en ough chlorophyll to naturally sustain their health and growth. Both can easily be controlled by usin g Searles Congua rd and Wettable Sulphur when the plants aren’t in flow er. The major fungal problem associate d with azaleas is petal blight. This is primarily caused by excessive moisture in and ar ound the plants w hile in full bloom. This is evid ent from the rapid browning of the flowers turning them slimy and lim p while still remaining on the plant and will affe ct the entire plant and any (pos sible) neighbourin g azaleas. The sun tolerant forms (as mentioned ea rlier) seem to have much greate r tolerance to this disease and are rarely affecte d. Spraying a truste d fungicide such as Searles Man cozeb Plus in the weeks prior to flowering will co ntrol this outbreak . Removal of all fallen foliage an d flowers around the base of the plant is also hi ghly advised as th e spores of the fungal problem ca n remain viable in the surrounding soil. Petal blight is mostly witnessed in regions with high rainfall levels during the spring flowering season.

Pink within the garden is a happy and vibrant colour, whether it be pale pink, strawberry pink or hot cerise, it is always welcome and planted often at my place.
Claire Bickle
These fantastic non stop flowering spreading little plants are just amazing. They can look spectacular in baskets, pots and in ground.
The colour pink is now the known colour for Breast Cancer Awareness. The month of October each year has seen millions of dollars raised over the years for breast cancer research, prevention and support through pink merchandise which ranges from the ribbons to roses. So whether you’re supporting breast cancer awareness or just a lover of pink in the garden here are some tried, true and tested pink favourites of mine.
Pink Perennial: Salvia spp & cv.
Now this is a very large genus of plants and there are a multitude of species plus all the named cultivars, so for me to choose one to showcase is almost impossible. Perennial forms vary in height from 30cm to 3m+ and can be anywhere from small delicate border plants to show stopping large spreading shrubs such as the cultivars of the Salvia involucrata species. ‘Wendy’s Wish’ a cultivar of Salvia buchananii has been very popular the past few years, as have a great range of the Salvia greggii cultivars. They are all wonderfully hardy, bee and butterfly attracting plants and are easy to grow from cuttings. Grow in a sunny location with good drainage and prune back after flowering to maintain bushiness. They also make great cut flowers.
Pink Native: Grevillea cv. Brush flower forms – ‘Lollypop’, ‘Flamingo’, ‘Sylvia’, ‘Misty Pink’, ‘Pink Surprise’.
These are the super models of the grevillea world. Some will disagree but these Grevilleas are just a sight to behold when in full flower. The flowers are arranged into a cylindrical brush shape and these forms generally do best in warmer climates. Grevilleas require a sunny location, good drainage and low phosphorus fertiliser such as Searles Native Plant Food. Keep your Grevillea bushes looking good by tip pruning after each flower has finished, by trimming just behind the flower head. Hard prunes can be done on older straggly plants in the growing season. There are spider and toothbrush forms to choose from as well.
Pink Climbing: Podranea ricasoliana ‘Pink Trumpet Vine’
This vine will happily grow in most climatic zones and bears the most delicate soft pink trumpet shaped blooms during spring through to autumn. Grown successfully in sun or light shaded positions, such as arbours, fences, veranda railings, large baskets and even as a weeping standard. Very hardy and virtually a pest and disease free plant, as well as being drought tolerant once established. Prune when flowering has finished.
Pink Tree: Handroanthus spp ‘Pink Trumpet Tree’ ‘Tabebuia’
The pink trumpet tree is planted widely in some regions as street trees because of their hardiness and beautiful pink clusters of trumpet shaped flowers. In these tough growing locations they tend to be smaller in height but will grow anywhere from 6 to 12m. Some varieties available are the palest of pinks, white, yellow and also dark pink. You will still see these trees often labelled as Tabebuias. When in flower the Pink Trumpet Tree can sometimes look like fairy floss on a trunk, for the masses of blooms appear when the tree has lost all of its foliage.

Pink Favourites Luculia
Grow in a sunny location with regular fertilising through the warmer months and your ‘Pink Trumpet Tree’ will be growing in no time.
Calibrachoas ‘Cherry Blossom’ ‘Cherry Star’ ‘Double Rose’
They come in a huge range of colours and there are various tones of pink. The key to keeping these little beauties looking their best is to give them a decent prune now and then. This can be hard, as they never appear to stop flowering but it is important to stop them from going straggly in the centre and promote more abundant blooms. Grow in a sunny location, liquid fertilise on a regular basis and provide good drainage. This is a must, as they detest wet feet.

Named in honour of Australia’s first saint, Mary McKillop will grow up to 2.5m tall and 2m wide. This callistemon has deep green leaves, brilliant, pink-red new growth and cardinal red flowers from spring to summer.
Callistemons (or bottlebrush) are some of the most beautiful and versatile native plants in Australian home gardens. This group of floriferous trees and shrubs are unrivalled in their ability to bring colour and attract native birds to the garden.
Callistemons tolerate a range of soils from moist clay to sand and can be an excellent option where the soil is too clayey for other natives like grevilleas, banksias or waratahs. Callistemons will flower best in full sun, but can also perform well in part shade. They enjoy any climate from cool temperate to tropical as well as second line coastal conditions and medium level frosts. Use only a low phosphorus fertiliser that is specifically designed for Australian natives such as Searles Kickalong Native Plant Food. Keep callistemons well pruned after spring flowering and most will flower well the following autumn. Each time callistemons are pruned or the spent flowers are trimmed off, it encourages even better flowering next season, whether in spring or autumn. So the moral is, prune! Most callistemons will flower from spring to summer but with regular pruning can flower at any other time throughout the year.

Hydrangeas last wonderfully as cut flowers and look beautiful in a vase. Grow them in semi shade with protection from strong winds and hot afternoon sun. They prefer a rich, well drained soil and dislike drying out, so mulch well and water as necessary during dry weather. Protect from frost. Grow them in garden beds or large tubs. Coloured hydrangea flowers reflect the soil pH, where purple indicates neutral, blue means acidic, and pink, an alkaline soil. White hydrangeas don’t change with soil pH. Flowers are borne in late spring and can continue into autumn, depending on the variety and climate. Remove spent blooms to prolong flowering and prune just above two swollen buds in autumn. Scale and Sooty mould on lillypillies.
Plant now for a harvest in time for Christmas. Their red and green colour scheme can be a wonderful finishing touch with other Christmas décor. To avoid a watery-tasting crop, minimise watering as fruit approaches maturity.
After treatment! Healthy Plant.
Watch out for sca le affecting gardenias, roses, lilypillies and citrus. The sca le insect also produces ho neydew on the leaves wh ich encourages soot y mould and ant infestatio n. Treat scale and sooty mould with Searles White Oil or ready-touse Searles Pest Gun.

Spring is the time for lawns. For a wonderful green lawn right through to next year, start fertilising in early spring with Searles Robust® Lawn Booster. Searles Robust® feeds for up to 4 months and promotes slow thick, green healthy grass just like professional sports fields.
This compact variety produces masses of snow white double flowers with serrated edged petals and a spicy fruity fragrance. It’s pretty upright flowers are ideal for container planting, small garden displays, entertainment areas and low edging around garden beds or paving in a full sun or part shade position. 30cm H x 40cm spread.
If your lawn soil is hard and repels water, aerate with a garden fork or aerater, fill holes with the mix of sand and soil and sprinkle Searles Penetraide® onto the soil to promote better water penetration and it feeds your lawn at the same time. Bindii Spring is the time for painful bindii invasion in lawns. If you have ever walked on a bindii and felt the sharp pain they cause, you may be interested to know that it is actually the seed that forms the prickle. Bindii grow in the winter and sets seed from late winter to early spring. Spray now with Searles Lawn Perfect®. Repeat spraying is important to control weeds that have germinated after the prior spraying. It’s very important whenever using a weed spray, to use it in conjunction with Searles Spredmax. This increases the weedkiller’s effectiveness by helping it stick to the leaves of the weed.
Refer to our lawn weed chart for the correct spray to use on your lawn. www.searles.com.au

It is hard to find a great plant with lots of bright blue flowers. Here we have a dwarf shrub which flowers its head off. Size: 30cm spread x 30cm H.
Position: This plant
makes a statement in frost free gardens. Care: Keep soil moist with good drainage. Any well prepared garden in sun to semishade will be suitable area to plant this bright blue specimen. Liquid feed every two weeks with Searles Flourish Soluble Plant Food to keep the plant flowering.
These small, fuzzy, white insects distort new growth by sucking on the plants sap and the females excretions cover leaves with a sticky honeylike substance that attracts ants which in turn provides the right conditions for sooty mould. Watch out for these insects on citrus, roses, indoor and outdoor ornamentals with the onset of warm weather. Control infestations with Searles Pest Gun. The female mealybug lays her eggs, every 10 days, in a sticky white substance around the stem of the plant. Hence, repeat spraying may be necessary to control future outbreaks.

Mulberries (Morus spp.) are easy to grow organically in home gardens. Allow the berries — borne in spring and early summer — to blacken before harvesting because they do not ripen off the tree. Dwarf varieties suitable for pots and small gardens are available. Mulch well around the roots and fertilise with Searles Fruit & Citrus Food in early spring.
