The Complete Guide on How to Grow Zinnias
There are a few main things to keep in mind when growing zinnias at home. These include:
Choosing the Right Location
While choosing where to place the zinnias at home, pick a place where it will get full sunlight for at least six hours a day. Zinnias do well in soil that is well drained; thus, no excess water should be retained in the area.
If growing them in pots, choose varieties with drainage holes to prevent root rot. You will desire to put your zinnias in a location to be enjoyed from within the sight of their beautiful blooms, whether in your garden, balcony, or patio area. They’ll bloom perfectly in a sunny, cheerful spot.
Soil Preparation
Zinnias grow best in normal rich, good draining soil with a pH range of 5.5 to 7.0. If your soil is clayey or looks like it’s compacted, add organic matter like compost for improving its texture and drainage. You may mix some time-released fertilizer before planting.
Before sowing your zinnias, be sure to weed the soil, removing rocks and other debris that are presenting an unwelcome matting of the soil that impedes the growth of the zinnias.
Planting the Zinnias
Zinnias can either be directly seeded in the soil or raised through transplantation from a purchased plant at a nursery. If you are growing them with seeds, it should be directly planted into the ground after the last frost date has passed. Follow spacing and depth instructions on the package for placing the seeds.
In general, space transplants at least 6 inches apart when planting in the ground. Gently remove them from their containers before planting. Water well after planting to settle the soil around the roots.
Watering and Fertilizing
Zinnias need lots of water, especially in the hot period of summer. Still, beware of excess water, since it can turn into root rot or other diseases that might kill the plant. A good rule of thumb is to water deeply once or twice a week depending on the weather.
On fertilization, zinnias enjoy a once-a-week application of balanced fertilizer for them to remain healthy. You may still apply other organic fertilizers like compost tea or fish emulsion to foster good development.
Deadheading and Pruning
To be able to keep the blooms on the zinnias for a longer period, pruning of dead or faded flower heads need to be done regularly. This process is called deadheading, and it makes the plant grow more flowers instead of wasting energy on producing seeds.
You can further prune your zinnias by cutting back leggy or damaged stems. This will not only enhance the plant’s abridgment, but will naturally provide you with a bushier plant, which in turn gives you more blooms.
These are some of the basic tips for growing zinnias. Follow these simple requirements, and you will see flowers that render beauty to your garden all through the growing season. Well, so why not give it a try? Add some color to the outdoors with zinnias.
Does Soil Affect Zinnias’ Color?
Yes, soil can affect the color of zinnias in your garden. Basically, although zinnias usually do produce colorful blooms, variations in the pH and amount of certain nutrients in the soil can cause changes in flower intensity and hue.
For instance, the richest colors will be obtained on very slightly acid to neutral soils with a pH between 5.5 and 7. A higher phosphorus and potassium content in the soil generally improves the color and size of blooms.
On the contrary, soil that is unbalanced or depleted can lead to blooms that are less than dazzling and poor growth. Therefore, by improving the organic content of the soil, with the right proper pH, not only will the zinnias grow healthily, but their blooms will also sport brilliant colors, which a gardener looks for in his plants. To improve poor soil, besides fertilizer and mulch, consider roping in earthworms as well.
Mistakes to Avoid When Growing Zinnias
Although zinnias are easy to grow, there are some mistakes most gardeners should avoid for the best results.
- Overwatering: If this has been told earlier, it is because excess water really damages or sickens zinnias. Water deeply, but only when necessary. Do not wet the foliage unnecessarily to prevent fungal diseases.
- Crowded Planting: Zinnias require good aeration to avoid fungal growth and really bloom well. Set them out so there is at least 6 inches of space between them for good circulation.
- Non-Deadheading: The plants should not be allowed to get away without deadheading since this may result in fewer flowers or a short blooming period. Make it a routine work to remove spent blooms for successive profuse flowering.
- Pest Control: Zinnias are pretty resistant to pests, but still, there are aphids, spider mites, and caterpillars that brutally attack them. Keep looking for signs of an infestation and use proper ways to mitigate the damage. Applying insecticidal soaps, horticultural oils, or neem oil on affected leaves can help in controlling these pests.
- Fertilization Neglect: Zinnias can take off in poor earth, but regular feeding will make them do better. Don’t ignore fertilization, for it produces weak plants with less -than- stellar blooms.
By avoiding these common mistakes, you can ensure that your zinnias will be flourishing and full of color all season long in your garden.
