Zinnia may be grown from seed sown early indoors and transplanted outside after frost, or sown directly in the garden after frost, or from potted plants.

Sowing Seed Indoors:

  • Sow indoors 5-7 weeks before outdoor planting date in spring using a seed starting kit
  • Sow seeds ¼  inch deep in seed starting formula
  • Keep the soil moist at 70-75 degrees F
  • Seedlings emerge in 7-10 days
  • As soon as seedlings emerge, provide plenty of light on a sunny windowsill or grow seedlings 3-4 inches beneath fluorescent plant lights turned on 16 hours per day, off for 8 hours at night. Raise the lights as the plants grow taller. Incandescent bulbs will not work for this process because they will get too hot. Most plants require a dark period to grow, do not leave lights on for 24 hours.
  • Thin to one seedling per cell when they have two sets of leaves.
  • Seedlings do not need much fertilizer, feed when they are 3-4 weeks old using a starter solution (half strength of a complete indoor houseplant food) according to manufacturer’s directions.
  • Transplant hardened-off seedlings to the garden after the frost.
  • Before planting in the garden, seedling plants need to be “hardened off”. Accustom young plants to outdoor conditions by moving them to a sheltered place outside for a week. Be sure to protect them from wind and hot sun at first. If frost threatens at night, cover or bring containers indoors, then take them out again in the morning.  This hardening off process toughens the plant’s cell structure and reduces transplant shock and scalding.

Sowing Directly in the Garden:

  • Direct sow seeds in average soil in full sun after all danger of frost.
  • Prepare the soil by removing weeds and working organic matter into the top 6-8 inches of soil; then level and smooth. 
  • Most plants respond well to soils amended with organic matter. Compost is a wonderful form of organic matter with a good balance of nutrients and an ideal pH level, it can be added to your planting area at any time. If compost is not available, top dress the soil after planting with 1-2 inches of organic mulch, which will begin to breakdown into compost. After the growing season, a soil test will indicate what soil amendments are needed for the following season.
  • Sow seeds evenly 12 inches apart and cover with ¼ inch of fine soil.
  • Firm soil lightly with your hand, water and keep evenly moist.
  • Seedlings will emerge in 7-10 days.
  • Thin seedlings to stand 18-24 inches apart, depending on the variety, when they are about 1-2 inches tall.

Planting in the Garden:

  • Select a location in full sun with good rich moist organic soil.
  • Prepare the bed by turning the soil under to a depth of 8 inches. Level with a rake to remove clumps of grass and stones.
  • Most plants respond well to soils amended with organic matter. Compost is a wonderful form of organic matter with a good balance of nutrients and an ideal pH level, it can be added to your planting area at any time. If compost is not available, top dress the soil after planting with 1-2 inches of organic mulch, which will begin to breakdown into compost. After the growing season, a soil test will indicate what soil amendments are needed for the following season.
  • Dig a hole for each plant large enough to amply accommodate the root ball.
  • Place the top of the root ball even with the level of the surrounding soil. Fill with soil to the top of the root ball. Press soil down firmly with your hand leaving a slight depression around the plant to hold water.
  • Water thoroughly, so that a puddle forms in the saucer you have created. This settles the plants in, drives out air pockets and results in good root-to-soil contact.
  • Use the plant tag as a location marker. 
  • Keep weeds under control during the growing season. Weeds compete with plants for water, space and nutrients, so control them by either cultivating often or use a mulch to prevent their seeds from germinating. 
  • Mulches also help retain soil moisture and maintain even soil temperatures. For annuals an organic mulch of shredded leaves lends a natural look to the bed and will improve the soil as it breaks down in time. Always keep mulches off a plant’s stems to prevent possible rot.
  • Keep plants well-watered during the growing season, especially during dry spells. Plants need about 1 inch of rain per week during the growing season. Use a rain gauge to check to see if you need to add water. It's best to water with a drip or trickle system that delivers water at low pressure at the soil level. If you water with overhead sprinklers, water early in the day so the foliage has time to dry off before evening, to minimize disease problems. Keep the soil moist but not saturated.
  • Until plants become established, some protection from extreme winds and direct, hot sunlight may be necessary. Good air movement is also important.
  • After new growth appears, a light fertilizer may be applied. Keep granular fertilizers away from the plant crown and foliage to avoid burn injury. Use low rates of a slow release fertilizer such as Flower-tone, as higher rates may encourage root rots.
  • Pinch young plants to encourage branching unless you are growing them exclusively for cut flowers and want long stems.
  • Remove spent flower heads to keep plants flowering until fall. Zinnias make terrific cut flowers, and cutting the flowers encourages new blooms.
  • Monitor for pests and diseases. Check with your local Cooperative Extension Service for pest controls recommended for your area.
  • Remove plants after they are killed by frost in fall to avoid disease issues the following year.
  • Plant zinnias in mixed plantings with other summer-blooming annuals, or place small groups of zinnias among perennials. They are at home in cottage and children’s gardens, and they are often grown in cutting gardens.
  • Shorter zinnia varieties are ideal for containers. Take care not to overcrowd them or the flowers may be significantly smaller than they should be and the plants may be taller. Always use a commercial potting mix, do not use garden soil, and make sure the containers have adequate drainage. Container grown plants will require extra water and fertilizer, look for signs of wilt or a nutrient deficiency.
  • Cut stems before the flower is open for cut flowers.
  • Zinnias attract hummingbirds, butterflies and beneficial insects.

Zinnia, Giant Flowered Mixed Colors is rated 5.0 out of 5 by 8.
Rated 5 out of 5 by from Magnificent I plant zinnias every year. For some reason I have never planted these giant zinnias until this year. They are astounding. They create a forest of flowers as tall as me and can be seen easily from the street. They have received so many compliments! With the butterflies landing on them one could hardly hope for a more lovely bed of flowers. They thrive in my hot, humid climate and that's saying a lot. I will never go without them again and will expand the planting as they are such successful growers. Need I add highly recommended?

Rated 5 out of 5 by from Cheerful Bouquets into October These seeds truly do produce large beautiful flowers and lots of them. I plant them every year. They like sun, but can handle a bit of shade during the day. Once they start blooming, I have big bouquets non-stop until we have a hard frost. It's Oct. 22 and I currently have 3 large bouquets in my house with more flowers to cut outside. The seeds produce many colors: pale pink, bright pink, red, yellow, orange, red-orange, coral, white, salmon, lilac, and fushia, for a very colorful bouquet. The butterflies also love them.

Rated 5 out of 5 by from A staple in our garden Easy, tall, great flowers and excellent colors. Make fabulous cut flowers to romancing your wife. I start mine indoors in Jiffy peat pots under standard UV light for sixteen hours a day. 95% of seedlings germinate under these conditions which allows for greater success than starting outdoors and more accurate placement. Have transplanted from peat pot to peat pot without a problem in past. Pure fun!

Rated 5 out of 5 by from Best Big Zinnia show I grow these every year and love them. They get 4-6 feet tall and nice and wide if you keep cutting the flowers. I have to admit I dont cut them as much as I should because the butterflys are so beautiful on them. The hummers love them too. I grow them up against a fence that I tie them to. You really need a good support for them...but boy is it worth it. The colors are just amazing.. people who come to my garden fall in love with them. Start them indoors and transplant after ALL danger of frost is gone. They hate any cold, so dont rush putting them outside. Stake the transplants as soon as you put them out and they will grow better.

Rated 5 out of 5 by from Great performance all summer long! These zinnias are fantastic with their large, showy blooms and yield. I sowed these directly into silt-loam soil with a 100% germination rate. The 3-4 ft blooms brightened my deck border and attracted butterflies and hummingbirds like crazy. I also enjoyed cutting these for bouquets that would last a few days. The plants bloomed in early summer and continued flowering until the first hard frost. Giant flowered zinnias are now a staple of my annual flower garden.

Rated 5 out of 5 by from Must have Zinnias I bought a packet of these zinnia's, started them in peat pots and then planted them in my mailbox garden last summer. These flowers were gorgeous! Very large blooms and beautiful colors that continously bloomed until the end of October. The butterflies and goldfinches loved them too. My only regret is that I only bought one packet of seeds. I will definitely be purchasing more and adding them to other areas of my yard this year.
