Common issues

Seasonal issues, particularly powdery mildew, are common in the summer months. This fungal disease strikes when conditions are optimal. If you spot white or grey spots on plants that previously appeared healthy, they are likely infected.

A mixture of dry foliage, high humidity, and low light all create the perfect environment for powdery mildew to thrive. In certain cases, this disease will take over entire plants, shrubs, and flowers. The end result? Plant defoliation, twisting, and the browning of leaves. This all leads to fewer flowers.

Thankfully this disease isn’t fatal and can be treated easily. Begin by ensuring the plant has sufficient sunlight and good air circulation. You can also create homemade remedies to treat this disease, including a concoction of skimmed milk, mixed with one part milk and two parts water.

The enzymes in the milk are able to counteract the fungus without damaging the plant.

When considering what to plant in your summer garden, it’s important to do your research. Think about what colours compliment each other and what plants work well growing alongside one and other.

Certain plants will hog the nutrients from soil and water, which means they are best planted in a flower bed alone, while others will happily sit among an abundance of other shrubs, vegetables, and flowers.

For a summer garden that lasts the entirety of summer, choose long-lasting blooms and plant them at the correct time.

Start growing some plants. Should you prefer flowers or plants, garden centers, and online florists have an abundance of choice, many of which offer same and next day flower delivery.
