The fabulous rose blooms that you’ve been waiting patiently for are also being eagerly anticipated by some very hungry caterpillars. Caterpillars can chew through and into rose buds as well as eating leaves. Control these destructive caterpillars by spraying roses thoroughly every 2 weeks, including the undersides of foliage where caterpillars often hide, with Yates® Rose Gun. Other common insect pests of roses such as aphids, thrips, whitefly and two-spotted mites will also be controlled with Yates Rose Gun, together with dreaded rose black spot disease.
Every 6 – 8 weeks feed roses with Yates® Thrive® Natural Roses & Flowers Organic Based Pelletised Plant Food. Spread the pellets around the root zone of both in-ground and potted plants. Yates Thrive Natural Roses & Flowers contains a special combination of more than 50% natural ingredients, boosted with fast acting fertilisers, including flower-promoting potassium, to encourage both vigorous green leaf growth and lots of beautiful roses. Also take the opportunity to refresh or apply mulch around the base of rose bushes. Mulching has several benefits:
- It helps reduce the amount of water splashing up from the soil onto the leaves, which decreases the risk of leaf diseases.
- Mulch helps to keep the soil moist and protect the delicate top soil from baking sun.
- Organic mulches, such as bark chips and Lucerne straw, will break down over time and add valuable organic matter to the soil.
