In terms of temperatures, Petunias usually prefer those climates from the warmer zones. These plants perform best in daytime temperatures that range from 60 to 75 °F (16-21 °C) and 55 to 65 °F (13-18 °C) at night. They can also withstand temperatures that drop to 40 °F (4 °C) or so, but freezing conditions or frost can damage them irreversibly.
In general, Petunia flowers do not encounter any serious problems with diseases or pests. If you are growing them in improper conditions, however, things may get a bit troublesome. They become susceptible to fungal diseases like grey mold and various pests including budworm caterpillars and aphids.
The best way to avoid these issues is to look for Petunia varieties that have a higher tolerance to moisture. In cases with fungal diseases, you must remove the infected parts from your plants and apply a suitable fungicide. If you notice any suspect presence on their foliage, you can handpick the intruders or spray them off your plants. For severe infestations, you should also use an insecticide.
Planting Petunias
Petunias are not very picky regarding their growing medium. Typically, these plants prefer light and fertile substrates with a slightly acidic soil pH. Yet, they can grow just fine in a wide range of soils as long as they have excelent drainage properties.
Plant your Petunia flowers in spring when you are sure that the danger of winter frost has passed. At the time of planting, make sure you apply a balanced fertilizer to your baby Petunias. These plants will also benefit from regular fertilizing from July through autumn. During this period, feed your plants with a liquid fertilizer designed for flowering plants once every two weeks.
You can encourage more branching and a fuller overall look by pinching the stems of your Petunias back. Depending on the age and size of your plants, this process will be different from one specimen to another. If you have short seedlings, you have to pinch them an inch (2.5 cm) or less. For gangly seedlings or mature plants, you can pinch the stems back by half.
Although younger Petunias do not require deadheading, many varieties will bloom more profusely if you are doing it once in a while. Older Petunia plants, however, will need regular deadheading to keep them in bloom. During their flowering season, remove the spent blossoms to allow new ones to flourish.
Watering Petunias
Petunias are flowering plants that do not appreciate dry conditions for too long. On the other hand, they can become victims of root rot if you provide them with too much water. But you don’t need to worry, the process of watering these flowers is not as hard as you would imagine.
In general, Petunia plants get the needed amount of water from regular rainfalls. In regions with seldom rainfalls, these flowers will grow at their best with weekly watering. In addition to that, potted plants or spreading varieties will require more frequent watering than usual.
For an optimal watering routine, make sure you do not allow their soil to dry out more than two inches (5 cm) deep. If your Petunias grow somewhat leggy and produce very few flowers, this may be a sign that you are giving them too much water. When it comes to humidity, low to moderate levels are ideal for Petunia plants.
Propagating Petunias
Luckily you can already purchase young Petunias from nurseries and be all safe and happy. But every gardener secretly dreams to try their hands at propagating although it can be a bit of a challenge. If you want to spice things up in your garden, starting Petunia plants from seed can surely bring you this kind of excitement! This is a good propagation method if you also want to obtain a particular variety.
For the best growth, it is mandatory to propagate Petunia plants through seeds at the right time. Typically, you should sow the seeds about 10 to 12 weeks before the last sign of frost in your region. If you are doing this properly, the seedlings will have enough time to develop until spring.
First things first, sow your Petunia seeds above a moist seed-starting mix. Make sure you do not cover them with soil because they will need lots of indirect sunlight to show nice results. Secondly, cover the container with a clear plastic wrap and place it in a well-lit, warm area. After one week or so, when you notice tiny seedlings emerging, you can remove the plastic for good.
Provide your Petunia seedlings with water regularly to maintain their soil slightly damp. Once they have produced 3-4 leaves, you can transplant them in their permanent locations. However, do not forget to save some potted babies for your special family members or friends!
In Conclusion
Petunias have all it takes to be your next ornamental buddy. Not only do these plants look absolutely fabulous, but they are also very easy-going with their owners and other companion plants. Once you find a cultivar (or more) that is to your liking, you can start to fill your garden with beautiful flowers!
