Zinnias are easy to grow from seeds and can be direct-sown into the garden after the last spring frost. They prefer full sun and well-draining soil. To encourage bushier growth, pinch back the growing tips when the plants are young.

For a unique twist, try growing 'Zowie! Yellow Flame' zinnia, which features bi-colored blooms with a striking yellow center surrounded by a fiery red edge. This variety adds a bold pop of color to any garden bed.

While many people associate gardening with spring and early summer, there are plenty of vegetables that can be planted or sown in late summer for a fall harvest. Choosing heat-tolerant vegetables ensures that your garden remains productive until the first frost.

One of the most popular late-season vegetables is the radish. These quick-growing root vegetables can be harvested in as little as 30 days, making them an excellent choice for succession planting throughout the summer and fall.
