Heat-Tolerant Annuals That Bloom All Summer Long
These annuals make gardening in the heat anything but impossible. And they'll bloom throughout the entire season!
Believe it or not, some plants actually like to be hot. While most plants will suffer in the summer when temperatures rise, we're here to talk about annuals that can take the heat—and actually like it!
All of these annuals grow well in containers. The smaller the container you use, the easier it will dry out, so be sure to pick a large container for your annuals. For an eye-catching container garden, utilize plants that require the same care but differ in colors, heights, and textures.
Although these annuals beat the heat, they also like to stay hydrated, so give them a drink every other day. Editor's Tip: To know if your pot needs to be watered, stick your finger into the dirt. If the dirt is dry, your pot needs water. If it's not, you can probably wait another day.
Be aware that if you rely on rain to water your plants, the water from the rain will most likely hit the leaves and fall off, rather than dampening the soil. In other words, don't trust that water from rain is giving your plants a decent water supply—a hose will do a better job.
To ensure that your annuals bloom all season, be sure to deadhead blooms that look wilted or dead. This will make room for fresh, new blooms to take their place.
