Flowers can be "singles," with petals lined up in a row around an open center, or semi-doubles, or doubles. All work marvelously in floral arrangements. Of course, the tall varieties are the zinnias of choice for cutting: 'Benary's Giant' is famous for its three-foot-tall, sturdy stems and large flowers. Cut zinnia stems at an angle just above a bud joint. Zinnias are typically long-lasting in a vase—strip the stems of all but the most visible leaves before setting them in water.
Zinnias are low maintenance. Since they're fast-growing, they shade out weeds. They don't require much in the way of fertilizing just an occasional well-balanced mix , and they don't need mulching. Deadheading helps to produce more flowers. No time to deadhead?
The Zaharas mentioned in the sidebard are self-cleaning—a real time saver when it comes to a large bed. Like Zaharas, the Profusion Series hybrids between Z.
Because zinnias are native to the grasslands of the southwestern states, Mexico, and South America, they know how to handle dry conditions. But wet summers we've had one so far can take their toll.
And that can lead to powdery mildew and leaf spot. Three suggestions for dealing with wet conditions:. It's easy to save zinnia seeds. They would do better in a container on a porch or balcony. Received a packet of Zinnia seed, Pompom, as a gift and planted them in a large tub about a week ago, they are sprouting already, in full sun and we have had some rain. Should I try and transplant them or just thin them out?
I also want to collect the seeds at the end of the season. I am in zone 3. Hi Joanne, Once the Zinnia seedlings are about 3 inches tall, it would help their growth to thin them to 6 inches apart. You could also try to transplant some that you are thinning out. To save the seeds at the end of the season, wait until the flowers finish blooming and then leave them there for the seed pods to develop.
Let the seed pods dry until they are brown and crunchy. Cut the pods from the flower stalk and break open the pods to harvest the seeds. Save the seeds in a sealed bag or container and place in a dry, cool place until the following year. This year, I have had to plant a "brand new" generation of zinnias. For the past 5 years I have saved the end of the seasons zinnia seeds to be re-planted the next year.
This rotation has gone on successfully for the past FOUR years!! My zinnias were several ft. This year, the seedlings were not spouting as I suspect I waited way too long to retrieve their seeds. This year, I will be awaiting something new!
I just wonder if Zinnia can be bloom in December? I'm planning to sow this last quarter of the year. In Phoenix we could see them bloom in fall.. February starts spring. So the answer is it all depends on location. I have Zinnias in my yard and would like save seeds for next year.
How do I get seeds from this years plants? To save zinnia seeds, wait until the flower is completely shriveled and dry. The seed of these plants will be attached to the shriveled petals. Place the envelopes in a glass jar or air tight plastic container. Seal the container and store it in the back of your refrigerator.
Tip: To keep the seed dry, you could add one of those little packets of Silica Gel Desiccants which absorb moisture. Or, a tablespoon or two of powdered milk wrapped in a facial tissue and placed in the seed storage container will also work to absorb excess moisture from the air.
My first time with zinnias from seed this year I have plants over 5' tall. Must be the year old "seasoned" manure my neighbor shared from her horses! I was successful two years in a row with sowing Zinnia seeds directly into the ground. But by the third year, the critters ate the sprouts as they came up. I was so disappointed as these flowers are so easy and beautiful. I planted big beautiful grown Zinnias at my condo community entrance this year; and a critter got into one of them!
What critter do you suppose did this? We have lots of rabbits and I've noticed a squirrel roaming the area. Any suggestions and thoughts? Other sources recommend rotating these plantings, too, for best results yes, rotating flowers, not just veggies. Skip to main content. You are here Gardening » Growing Guides. By Catherine Boeckmann. From seed, they will grow very quickly in the right conditions. Zinnias are sensitive to frost, so do not seed until the last frost has passed. See your local frost dates.
Sow a round of seeds every week or so for several weeks to extend the flowering period. Choosing and Preparing a Planting Site Choosing a location that gets full sun is essential. They come striped, speckled, solid and multicolored. To have blooms from early summer to frost, Michigan State University Extension suggests dead heading zinnias. Dead heading helps to promote the zinnias to keep preforming throughout the season.
Nevertheless, zinnias get tired, so I recommend succession plantings of zinnias every two weeks. I plan succession plantings commencing in late May and continue through about the first week of July. This guarantees showy blooms through late September. It is not too late to plant a few zinnia seeds for late summer color that will last until the first frost.
Many varieties of zinnias will last from seven to 12 days in a vase. Flower farmers will attest that zinnias with their brilliant colors, easy care and long vase life are one of the most profitable flowers to grow.
