Keeping Your Flowers Happy In The Heat

As the mercury soars, it’s not just humans who feel the heat, but our plant friends as well. So how can you ensure your beloved flowers stay happy in the sweltering Australian heat this summer? Let’s delve into this subject with some useful tips.

Understand Your Flowers’ Heat Tolerance

The first step in creating a flourishing garden is understanding the heat tolerance of your flowers wollongong. While some blooms, such as roses and geraniums, thrive in the heat and bask in the sun’s rays, others are more delicate and wilt at the first sign of a heatwave. By carefully selecting and accommodating your garden with a variety of heat-tolerant flowers, you’ll ensure a vibrant and resilient garden that stands strong even in the harshest of summers. So, go ahead and choose those hardy blossoms that can withstand the scorching temperatures, and watch your garden bloom with beauty and vitality throughout the season.

Watering Wisely

Hydration is absolutely crucial in the scorching heat. However, it’s important to water your plants wisely to ensure their well-being. Over-watering can lead to root rot, which can be detrimental to the health of your plants. On the other hand, under-watering can cause your flowers to become dehydrated and wilt. To strike the right balance, it’s recommended to water your plants in the early morning or late evening when the temperatures are cooler and the water has a better chance to be absorbed by the roots. This way, you can ensure that your plants receive the necessary hydration without any adverse effects.

Mulching Matters

Mulching can be a lifesaver for your delicate flowers, especially during the scorching heat. By creating a protective layer over the soil, mulching not only helps in maintaining a consistent soil temperature but also acts as a shield, preventing excessive moisture loss. Moreover, the added benefit of mulching is its ability to suppress weed growth, ensuring that your flowers receive all the nutrients they need without any competition. When it comes to organic mulches, options like straw, bark, or compost prove to be excellent choices, providing additional nourishment to your beloved plants.

Proper Pruning

Pruning is an essential and often overlooked step in the care of your summer flowers. By delicately removing dead leaves and wilted flowers, you not only enhance the aesthetic appeal of your plants, but also enable them to redirect their precious energy towards their own survival and vigorous growth. This thoughtful act of nurturing ensures that your flowers thrive and bloom with renewed vitality, adding a touch of natural beauty to your surroundings.

Create Some Shade

If the heat is too intense and your flowers are wilting under the relentless sun, it’s a good idea to provide them with some much-needed shade. You can do this by using garden umbrellas or shade cloths, strategically placed to shield your blooms from the scorching rays. By giving your flowers a break from the heat, you’re ensuring their well-being and allowing them to thrive even in challenging weather conditions.

Fertilising: Less is More

In the heat of summer, when temperatures soar, it’s advisable to adjust your flower fertilisation routine. It’s best to reduce the frequency of fertilisation to avoid overstimulation, as excessive growth can render your flowers more vulnerable to the harsh effects of heat and potential diseases. By carefully managing the balance of nutrients, you can ensure the optimal health and resilience of your beloved blooms even in the scorching weather.

Natural Remedies for Preventing Heat Stress in Flowers

When it comes to warding off heat stress in your blooms during sizzling summer months, there are several natural remedies you can consider. A simple yet effective practice is the installation of bird baths or water features. They create a microclimate in your garden, promoting humidity and providing a cooling effect. Also, companion planting can be a strategic way to provide natural shade to those flowers which are less tolerant to heat. For instance, planting tall, sun-loving flowers next to those that prefer cooler conditions can create a protective canopy, shielding them from the harsh sunlight.

Another natural remedy is the usage of seaweed extract as a soil supplement or foliar spray. It bolsters the plant’s health and helps it to better manage heat stress. Seaweed extract is packed with beneficial micronutrients and growth hormones that can enhance your flowers’ heat tolerance, making it an excellent natural choice. Finally, remember the old saying, ‘prevention is better than cure’. Keep a close eye on weather forecasts and plan your gardening activities accordingly to prevent heat damage.

Keeping Bouquets Happy in the Heat

Just as with garden flowers, bouquets also need careful attention during hot weather to ensure they retain their fresh and vibrant appearance. To help your bouquets combat the heat, consider the following tips:

Placement is Key

Avoid placing your bouquet near a window or any other location that gets direct sunlight. Heat can speed up the wilting process of the flowers. Instead, try to find a cool, shaded spot in your home that gets indirect sunlight.

Hydrate Regularly

Just like humans, flowers need hydration to beat the heat. Ensure the vase water is changed daily, or as soon as it begins to look cloudy. This will not only hydrate the flowers but also prevent bacterial growth.

Use Flower Food

Most florists provide small packets of flower food with their bouquets. These contain a balanced mix of nutrients to promote flower health and longevity. Simply add it to the vase water according to the packet instructions.

Trim the Stems

Trimming the stems of your bouquet flowers every few days will help them absorb water more efficiently. Remember to cut at a 45-degree angle for the best absorption.

Remove Wilting Flowers

If you notice any flowers starting to wilt in the bouquet, remove them immediately. Wilting flowers produce ethylene gas that can hasten the wilting of other flowers. By removing wilted flowers, you’re helping the rest of the bouquet stay fresher for longer.


Caring for flowers in summer heat can be challenging but not impossible. With proper watering, mulching, pruning, shading, and natural remedies, you can keep your blooms healthy. Hydration, flower food, trimming, and removing wilting flowers will also keep bouquets fresh. Understanding your flowers’ needs helps them thrive, bringing vibrant beauty to your surroundings.
