Zinnia seeds can still be planted now for late summer color that will endure until the first frost. Additionally, they produce stunning cut flowers with a lengthy vase life.
Even the most inexperienced gardener should grow zinnias because they are one of the tried-and-true garden flowers. My first memories of gardening are when I first encountered zinnias. The bush beans and tomatoes set aside for zinnias were a constant source of conflict. My favorite annual flower is still the zinnia, and they now have a prime location next to my back deck where I can enjoy them in the warm weather.
Growing zinnias is simple; they prefer full sunlight and well-drained soil. They may be planted directly in the garden or transferred. Plant them in a peat pot that can be placed directly into the garden or planting bed if you decide to have a head start and want to transplant so as to avoid disturbing the roots.
There are many different types of zinnias. They come in sizes ranging from 6 inches to nearly 4 feet, from dwarf to enormous. The flower heads are available in many different forms, including single and double flowers, spidery shapes, and domes.
The amazing variety of hues is the best feature. The palest pastel hues to the brightest hues are all available in zinnias. They come in solid, multicolored, striped, and specked patterns.
Dead heading zinnias is advised by Michigan State University Extension to ensure flowering from early summer through frost. Zinnias are encouraged to continue performing by dead heading throughout the season. But because zinnias fatigue, I advise putting them in succession every two weeks. I intend to plant in succession beginning in late May and continuing until the first week of July, roughly. This ensures spectacular blooms through the end of September. It’s not too late to plant some zinnia seeds for color that will persist through the first frost in the late summer.
In addition to their amazing garden display, zinnias make fantastic cut flowers and may be used anywhere you need a splash of color. Many zinnia cultivars can stay in a vase for seven to twelve days. The mainstay of the farmer’s market is zinnias as well. Flower farmers would tell that zinnias are one of the most profitable flowers to grow due to their vibrant colors, ease of maintenance, and extended vase life.
The zinnia variants “Benary’s Giant” and “Cut and Come Again” are two of my favorites. Their surnames are biographical. On tall stems that stand between 40 and 52 inches in height, “Benary’s Giant” has huge blooms and dazzling flowers. Cutting the stem just above a bud junction will encourage “Cut and Come Again” to produce continuously throughout the growing season, as will all zinnias.
In July, may I plant zinnias?
Nowadays, not many flowers are cultivated from seeds, but zinnias are worthwhile. These simple summer annuals reward the grower with colorful flowers up to six inches across that complement both urban and rural gardens and make lovely bouquets.
My summer flower garden last year got off to a late start, with my zinnia seeds not being planted until July. May or June is the suggested time so that plants can establish themselves before the sweltering summer heat.
I went to my local nursery and purchased many packages of zinnia seeds as I hadn’t placed a catalog order. But I also bought some zinnia seedlings in the hopes that they would produce a yield earlier.
To my amazement, the nursery seedlings only blossomed 10 days before my seed-grown plants did, despite having a lead start. Although the blooms in each group were beautiful, the plants grown from seeds cost a fraction of what I paid for nursery plants, and the seeds produced hundreds of plants—many more than I needed.
Zinnias are available in a huge range of shapes and sizes. The huge, cactus-flowered blossoms with mop-headed daisy-like heads are my favorites. The tiny lilliput (pompon) species, whose thickly packed petals resemble parrot feathers, is another favorite of mine.
The Haageana or Mexicana variety features 1 1/2-inch flowers with pointed petals bordered with a contrasting shade, as opposed to the more formal dahlia-flowered zinnias, which have huge blooms with flat petals.
It’s laughably simple to grow zinnias. Children frequently perform on par with skilled gardeners. Contrary to petunias or snapdragons, the seeds are huge, making it easy to seed them and give them the proper spacing.
Make a furrow in the prepared soil that is about 1 inch deep. The seeds should be deposited four inches apart. To prevent the seeds from being washed away, cover with one-eighth inch of soil and water lightly. Till the seeds sprout, which typically takes four to eight days, keep the soil moist. Transplant any surplus seedlings to bare places or pots after thinned to a distance of 10 inches.
Mildew is the main issue with zinnias, especially where I live near the shore. Planting zinnias early enough in the summer to allow them to bloom before late September, when the days start to get shorter and the plants get more damp at night, can lessen its effects. It’s also a good idea to water the roots solely, leaving the foliage dry. Spray a fungicide, such as Funginex, on the leaves at the first indication of a white powder coating them.
I experimented with Z. augustifolia one summer (also called zinnia classic, Z. linearias, or thin-leaved zinnia). Although its 1 1/2-inch golden-orange semidouble blooms were not as eye-catching as modern hybrids’, the plants did have one enticing quality that made them stand out: they did not develop mildew, even in my humid climate.
Now I find that the Z. elegans and Z. augustifolia hybridizers at Burpee have produced a pink, 2 1/2-inch bloom that is supposedly mildew-resistant. In the flower garden this summer, I can’t wait to test this new type, Rose Pinwheel.
I’ll also plant pink cosmos, pink statice, rose cleome, blue salvia (S. farinacea Victoria), rose shades of strawflower, and gloriosa daisies around it. Rose Pinwheel’s gold centers should compliment the gold daisies well, and blue is a great complementary hue in general.
I’ll start the strawflowers in flats a few weeks prior to planting them in the garden because they take longer to flower. The seeds for all the other plants will be planted right in the garden. Although blue salvia is simple to cultivate from seed, it takes several months before it starts to bloom, making it a summer flower that I typically buy from the nursery.
All of my plants will be cultivated next to soaker hoses so that I may use water as effectively as possible. My irrigation system is basic, despite the fact that some irrigation systems are fairly complex (with computer timers and multivalve stations).
I use 150 feet of soaker hose connected to the garden hose for each tier of my garden where annuals are sown. Twice a week, I let the water run gently for about five hours. I may decide whether to apply more or less by keeping an eye on the soil’s moisture level.
Several well-known zinnia strains can be acquired at garden centers for gardeners who like the speed and convenience of seedlings.
The biggest is State Fair, a dependable favorite that has been around for years and is dahlia-flowered. On 12- to 18-inch bushes, the Peter Pan, Pulchino, and Cut-and-Come-Again zinnias yield three-inch flattened blooms. Thumbelina, the smallest zinnia, is adorable but only blooms for a little period of time, making it seem hardly worth the effort.
Zinnias are a favorite of Terry Hartog, who grows thousands of bedding plants for his Vintage Nursery in Lakewood. Because of its relatively big blossom size and compact growth, he prefers a mass planting of Peter Pan that is surrounded by the white vinca Little Bright Eye. The bottom leaves of zinnias can grow unattractive, thus the vinca conceals them.
According to Terry, both vinca and zinnias are suitable for hot climates since they can withstand the heat.
The best assortment of zinnias may be found in catalogues like Burpee Gardens, Warminster, PA 18974 (with zinnias on the cover), and Park Seed, Greenwood, SC 29647-0001. The majority of neighborhood garden centers also carry a range of zinnia seeds.
How late may zinnia seeds be sown?
Look no further than zinnias if you’re looking to plant flowers for brilliant summer color. There are so many different zinnia kinds that it’s no wonder they’re so well-liked as cut flowers.
Zinnias can be planted outside in May, but they can also be planted indoors from February through April. Simply pick a productive, weed-free place, whether it be a hole in a fence or a patch of bare ground, and start planting.
As soon as they blossom, you may anticipate a riot of summer color that will last until the first fall frosts.

Step 3
In order to identify what you are growing, label the space and thoroughly water the seeds. As seedlings start to grow, keep the soil moist but not wet and cover with a cloche.
Zinnias for pollinators
Pollinating insects, especially hoverflies, are drawn to zinnias. Grow single-flowered kinds that don’t restrict pollinator access so they can get to the pollen and nectar.
Is it too late to sow seeds in July?
Contrary to popular belief, it is still not too late to sow garden veggies and herbs in July. Planting many consumables in the middle of the summer can result in a bountiful harvest in the fall, including both vegetables and herbs that produce numerous harvests. Depending on where you live, July could be too late to plant certain varieties, such as tomatoes or squash, but you can still choose seeds based on the conditions in your USDA Plant Hardiness Zone.
In August, may I plant zinnias?
Zinnias grow well in hot climates and are simple to grow from seed. Because the temperature is typically a little dryer in the fall, zinnia growing conditions are ideal. I advise sowing zinnia seeds by August 15th to enjoy them all fall long. After the first frost, they will go extinct.
Does July still have time for flower planting?
You might assume it’s time to store your planting trowel and gardening gloves now that the hottest days of the growing season have arrived. Not quite! In fact, you can grow a wide variety of edibles and ornamentals in July to get a second crop or spruce up drab flowerbeds, pots, and planter boxes. As long as there is still enough time before a frost, many different edible plants can still be started from seeds. To determine the earliest anticipated frost date in your region, contact the university cooperative extension service in your area (you can find it here). Then, start counting backwards. For instance, if the seed box states the plant needs “60 days to mature,” and your first frost usually occurs around October 15, you’re still in fine condition! For flower beds that no longer look their best, now is a terrific opportunity to visit the nursery and pick up a few new blooms. And even though it should go without saying, if there is a dry spell, keep everything watered!
Typically, you can plant the following in July:
It’s time to plant your pumpkin seeds if you want to use them for baking, decorating for fall, or carving. If you’re short on room, go for compact kinds, though such vines still need 6 to 8 square feet to flourish. Fill each hole with a few pumpkin seeds, and water regularly, especially when blossoms and fruits are developing.
Is it too late to plant flowers in August?
When designing your garden, consider using fall flower plantings. Perennial and annual flowers also enhance the beauty of the autumn environment, which is appreciated for its trees and shrubs with vibrant fall foliage. Fall flowers are available in a variety of hues, forms, and sizes that complement any garden design. When many other plants have finished for the season, hardy perennial fall flowers begin to bloom. Hardy selections might last the longest, but you should also consider include some colorful, delicate plants, such as violas or New England asters, which only bloom in the fall.
Your garden will benefit from fall plantings since the warm soil fosters root growth up until the ground freezes. Compared to a plant that is just getting started in the spring, the roots are well developed by early spring. In the fall, unsold annuals are also for sale. If you put them in your garden, they won’t survive for very long, but you can prepare them indoors for your garden the next spring by overwintering, dividing, or taking cuttings.
Tip
As long as it isn’t still too hot for the plants to avoid heat stress, mid- to late August is frequently a great time to grow fall flowers. However, if you wait too long to plant, you won’t have much time to appreciate your blooms. Check each plant’s growing requirements.
How long do zinnias take to grow from seed?
Beautiful flowers like zinnias are ideal for novice gardeners! These annual flowers come in a wide range of hues and variations, adding a vibrant pop of color to your yard and making them ideal for bouquet-making. Zinnias require only plenty of sun, warmth, and well-drained soil to thrive and can be grown without much care from summer until the first hard frost in the fall. They don’t have any significant pest issues and can draw lovely butterflies to your garden.
Depending on your location, the growing strategy may change slightly. When the temperature starts to rise, zinnia seeds can be sown immediately into the garden in warmer climates. Here in New England, it takes longer for the temperature to rise, so if you can keep the soil between 70 and 80 degrees F, you can start the growing process about a month before the final frost is predicted. Since zinnias dislike being transferred, sow seeds in peat pots that can be placed straight in the garden. From seed to flower, zinnias normally require two months, though this might vary depending on the weather.
Here are some more hints for growing zinnias:
- For your zinnias, choose an area that is sunny and bright.
- Zinnia seeds require sunshine to sprout, so only cover them with 1/4 inch of dirt.
- Keep the soil damp while the flowers grow.
- Thin seedlings to 6-8 inches apart for small varieties and 1 foot apart for large varieties when they are 2-3 inches tall.
- Avoid drowning the zinnias in water. Water intake of 1 inch per week is advised.
- To encourage the zinnias to generate more blooms, remove any faded or dead flower flowers. Deadheading is the term for this.
