These flowers prefer full sun and well-drained soil. They are also quite drought-tolerant, so they are a good choice for areas that don’t get a lot of rainfall.

Zinnia Care

These plants are one of the easiest flowers to grow from seed; they bloom abundantly throughout summer. Learn how to plant and how to care for and to enjoy these colourful annuals in your garden!

How to Plant

To plant, start by finding a sunny spot in your garden with well-drained soil. It prefers warm weather and will not do well in cool or cold climates. Choose a place where the plant will have plenty of room to grow. You can directly sow the seeds into the ground, start them indoors, and then transplant them outdoors.

To sow the seeds, lightly press them into the soil and keep the soil moist. The seeds will take about ten days to germinate. Once they have sprouted, thin them out, so they are about 12 inches apart. When transplanting, be sure to dig a hole that is twice as wide as the plant’s root ball.

Sun and Temperature

Zinnias need full sun to grow well. They also prefer warm temperatures and will not do well in cooler weather. If you live in an area with cool summers, you can start zinnias indoors and transplant them outdoors when the weather warms up.

Water and Humidity

The Zinnia flower needs at least 1 inch of water per week and prefers a humidity level of 40 to 50%. If the air is too dry, the zinnias will wilt. If the soil is constantly soggy, the zinnias will develop root rot.


The zinnia flower requires well-drained, sandy soil with a neutral pH. The soil should be amended with organic matter before planting.


To keep your zinnias healthy and blooming all season long:

  • Fertilize them regularly.
  • Use a water-soluble fertilizer and apply it according to the package directions.
  • Fertilize zinnias after being transplanted into the garden every two weeks throughout the growing season.

Zinnias will also benefit from a top dressing of compost or manure in early spring.


Pruning zinnias are essential to encourage new growth and to keep the plants from getting leggy. To prune, cut back the Zinnia stems by a few inches. This will enable the plant to produce more leaves and flowers.

Pinching zinnias is also helpful in keeping the plants compact and full of blooms. To pinch, use your fingers to remove the tips of the zinnia stems. This will cause the plant to branch out, resulting in more flowers.


To propagate Zinnias, sow seeds indoors 6-8 weeks before the last frost date. Sow Zinnia seeds on the surface of the well-drained root starting mix and lightly cover them with vermiculite. Keep the soil moist and warm until germination. Transplant zinnia seedlings into the garden after all danger of frost has passed and space them 12-18 inches apart.

Zinnias can also be directly sown into the garden after all danger of frost has passed. Sow zinnia seeds on the surface of the soil and lightly cover with ¼ inch of soil. Space zinnia seeds 12-18 inches apart.


If your zinnias are struggling, you can do a few things to help them out. Check for common problems and take steps to correct them. With extra care, your zinnias will bloom brightly in no time!

Growing Problems

One of the most common zinnia growing problems is powdery mildew. This fungal disease affects zinnias and many other plants, causing the leaves to develop a white, fine coating. Powdery mildew can eventually kill zinnias if left unchecked, so it is essential to take steps to prevent or control this disease if you plan to grow zinnias in your garden.

Several other zinnia growing problems can affect these popular flowers. These include leaf spot, root rot, and stem rot.


Pests found in zinnias flower gardens include slugs, aphids, and earwigs. These pests can cause zinnias to wilt, turn brown, and stop blooming. To control these pests, use traps or pesticides specifically designed for each type of pest.


Zinnias are susceptible to a few diseases, the most common being powdery mildew, leaf spot, and stem rot. These diseases can be controlled with the use of fungicides. If you notice any of these diseases on your zinnias, treat them immediately to prevent the spread.

Frequently Asked Questions about this Cheerful Flowers

Is zinnia a shade or sun?

Shade. Zinnia plants need at least six hours of direct sun each day to produce blooms. They will grow in partial sun, but they may not flower as heavily. The blooms on zinnias will be more compact and the plants will be shorter if they are grown in too much shade.

Is it a zinnia annual or perennial?

It depends on the variety. There are both annual and perennial zinnia varieties.

Where is the best place to plant zinnias?

Zinnias can be planted in either the garden or in containers. When planting them in the garden, make sure to space them about 12-18 inches apart. If you are planting them in containers, make sure to use a pot at least 8 inches deep with drainage holes. Zinnias do best when they are planted in full sun.

How do I keep zinnias blooming?

Zinnias are annual flowers that come in a variety of colors, and they are easy to grow. To keep them blooming, you’ll need to deadhead the flowers as they fade and fertilize them every few weeks. Zinnias also like plenty of sun, so make sure to plant them in a spot where they will get at least six hours of direct sunlight each day.

Should zinnias be deadheaded?

Yes, zinnias should be deadheaded. Deadheading is the process of removing the spent flowers from a plant in order to encourage new blooms. It’s a good practice to do with most flowering plants. Zinnias are particularly prone to developing buds at the base of their blooms, so it’s important to deadhead them regularly in order to keep the plants looking neat and tidy. If left unchecked, those buds will eventually grow into new flowers, but they’ll be smaller and less attractive than the original blooms.

Are coffee grounds good for zinnias?

Yes, coffee grounds can be good for zinnias. Coffee grounds are a great source of nitrogen, which is beneficial for plants. They also contain potassium and magnesium, which are both important nutrients for plants. adding coffee grounds to the soil around your zinnias will help them to grow healthy and strong.

How long do zinnia flowers last?

Zinnias can last anywhere from a few days to a week, depending on the variety and the weather conditions. The petals will start to wilt and curl inwards as they age, so you’ll know when it’s time to cut them off. Just make sure to snap off the stem close to the flower head, rather than pulling on the petals.

Are zinnias easy to keep alive?

Zinnias are easy to keep alive as long as you provide them with plenty of sunlight and water. They do best in a sunny location where they can receive at least six hours of direct sunlight each day. Water them regularly, and make sure the soil is moist but not drenched. Zinnias will bloom all summer long if you care for them properly.

How long do zinnias last after being cut?

Zinnias will last about one week after being cut. If you want them to last longer, you can place them in a vase with water and ( optionally ) a bit of sugar. The sugar helps the flowers to drink more water and stay hydrated, which makes them last longer

Do zinnias dry well?

Yes, they can dry well. Cut the blooms off the stem, and remove any leaves that will be below the bloom when it is hanging upside down. The key is to make sure there is plenty of water in the vase–zinnias can drink a lot! Put them in a bright, sunny spot and turn them every few days. You should have dried zinnias in about two weeks.
