If your garden has that barely alive look, then you may want to start thinking about a late-summer planting of marigolds or zinnias.
Many garden centers get in a fresh shipment of these annuals just before the mum season sets in. If yours does not, know that both can be grown easily from seeds. Planting over the next couple of weeks will set you up for a long period of blooming leading up to the first frost.
There is a new group of zinnias called the Zesty series to watch for.
The series is short, much like the Dreamland series. They produce huge dahlia-shaped blossoms on a great landscape plant. They come in a multitude of colors and have been very good performers.
Although leaf-spotting diseases are a problem with some varieties, Zesty zinnias' foliage will stay remarkably free of these signs. This makes the series an environmentally friendly performer in Southern landscapes.
When you consider that the colors of fall are oranges, yellows and reds, then the marigold may be the ideal plant. They are loaded with bold colors and bold flowers that range in size from a quarter to a tennis ball. While primarily considered for spring, they are ideal for planting this time of the year.
You may have come to hate your spring-planted marigolds because they are more susceptible to spider mites and now are loaded with them, especially in the heat of summer. The good news is that research in Texas has shown that marigolds planted in August are not nearly so afflicted by spider mites because their reproductive rates change as they head into fall.
There are some new varieties of marigolds that will be coming to the marketplace. One is Moonstruck. This is a huge flowered African marigold similar to Antigua, Inca and Marvel, but the flowers are larger and round. You will love this series. They will be available in orange and yellow.
Floranova, an innovative breeding company in the United Kingdom, brings us two new series of triploid marigolds, Zenith and Sunburst. If you have ever wondered what a cross between the African and the French marigold might look like, this is your opportunity. The plants are large, vigorous and packed with flowers.
The Sunburst series has five colors and features single-petaled flowers. The Zenith series has nine colors and a blossom more typical of a French marigold.
Lastly is a new marigold called Lunacy. This one has to be considered weird and wonderful and will most assuredly come as a pleasant surprise to the grower. The flowers are medium-large and resemble a small peony, except in marigold colors. You have to admit this is a fun time to be a gardener.
Prepare beds by incorporating 3 to 4 inches of organic matter and 2 pounds of a slow-release, 12-6-6 fertilizer per 100 square feet of bed space. Direct seed or set out transplants that have little to no color showing.
Both zinnias and marigolds combine nicely with other colorful fall flowers like mums, Mexican bush sage and asters. You will notice they bloom before and after mums, and they are downright inexpensive.
