Introduction

As summer temperatures reach 90 degrees and above, it's important to adjust watering routines to avoid drought stress for plants. The amount of water plants require depends on factors such as plant type, soil type, and weather conditions. In this article, we'll explore how often to water plants in 90 degree weather and provide some tips to help your plants thrive even in heatwaves.

Soil Type

The type of soil plays a key role in determining how often to water plants in hot weather. Sandy soils, for instance, drain water quickly, while heavy clay soils retain water, making it more difficult for plants to absorb. In 90 degree weather, sandy soils require watering more frequently, as they dry out faster than clay soils. On the other hand, plants growing in clay soils don't need watering as frequently in these conditions.

Plant Types

Different types of plants have different water requirements. For instance, plants with deep root systems require less frequent watering than shallow-rooted plants. Succulents and cacti, for instance, can survive long periods with little water, while annual flowers may need watering every day in hot weather. Moreover, some plants have adaptations that allow them to tolerate drought better than others. It's important to research the water needs of plants in your garden to avoid over- or under-watering.

Time of Day

The time of day when you water plants in hot weather matters, too. Watering during the hottest part of the day can lead to evaporation, and the water may not reach the plant roots. Instead, it's best to water plants in the early morning or late evening when temperatures are cooler. This reduces water loss through evaporation and allows the roots to absorb moisture more efficiently.

Container Plants

Plants grown in containers require more frequent watering than those planted in the ground as they dry out faster. When temperatures reach 90 degrees or above, container plants may need to be watered twice a day, especially if they receive direct sunlight. Be sure to check the soil moisture level regularly to prevent over-watering or under-watering.

Signs of Over-Watering or Under-Watering

Knowing the signs of over-watering or under-watering can help you adjust your watering routine. Over-watered plants may have yellow leaves and wilted stems, while under-watered plants may have dry soil, brown leaves, and wilting. To check for soil moisture, push your finger 1 to 2 inches deep into the soil- if it's dry, it's time to water your plant.

Conclusion

Proper watering is essential for plants to survive 90 degree weather. It's important to consider the type of soil, plant type, time of day, and signs of over- or under-watering when determining how often to water your plants. By following these tips, you can ensure your plants thrive even during heatwaves.
