How to plant, grow, fertilise and care for roses in Australia

Garden - How to Grow - winter rose growing care


Gardens just would not be complete without the magnificent scented rose flowers and winter is the best time to plant roses.

Roses love a full sun position and like room around them so they don't become overcrowded. When planting roses, make sure to leave about a 60cm space all around them.

Now the real trick for roses is in the soil preparation. Roses love a rich organic soil. For best results dig a hole and fill with Searles Fruit, Citrus & Rose Mix. Plant your roses straight into this planting mix. You'll be rewarded with stunning growth and magnificent blooms.

Roses need regular fertilising to keep producing their glorious flowers. An ideal fertiliser recommended and endorsed by the Qld Rose Society is Searles Flourish Soluble Plant Food. Apply Searles Flourish at planting and continue every 2-3 weeks. Searles Flourish is an instant plant food which the roots can quickly use the nutrients it needs to produce more flowers. 

Another preferred fertiliser, which promotes strong growth and helps protect roses from fungal diseases is SeaMax Fish & Kelp. Ideally, you could alternate between the two fertilisers every 2-3 weeks.

After each flush of flowering, be sure to prune back the finished flowers, as this helps promote more flowers. Always make sure you clean your secateurs thoroughly as this may pass diseases onto your roses.

During wet and humid conditions roses are susceptible to powdery mildew and black spot. Fertilising with SeaMax Fish & Kelp will enable the plant's resistance to the disease. If outbreaks are severe, control with Searles Rose Pro. This ready to use spray also controls pests like thrips, two-spotted mite and the common rose pest - aphids

If you do this, you will be rewarded with the most magnificent scented rose flowers.
