How to cut back petunias

Have you ever asked yourself, “How do I make my petunias fuller?” Preventing leggy petunias requires that you cut back the branches by one quarter or one half on a regular basis. This may be hard to do, as your petunia plant may be in full bloom when you do this. You can cut back all the branches at once.

Snip the stem back farther if the petunia stems are excessively long or if it is difficult to locate a node on the stem. Cut the petunia stems back to within 2 to 3 inches of the base, if necessary, since the plant will still be capable of generating new growth and blooms.

When Blooms Slow Down

Repeat the process on additional stems after waiting a week or so, then one more time in another week. It could take a month for new blooms to appear on the previously pruned stems. The plant will also produce more stem and leaf growth, making it appear fuller.

Cutting back petunia plants is not hard. You need to clip a few stems every week. The petunia plant will then produce two new growing tips just below each cut, and those tips will begin flowering soon. Pruning petunias regularly from the time you buy them will keep your plants gorgeous and healthy.

Petunias emit a gooey material via the tissues of their stems. The sticky stuff, in turn, travels all the way to their soft foliage. The goo is believed to be protection against insect nuisances like thrips and aphids, according to the Utah State University Extension.

1 – Petunias Look Wilted Despite Soil Being Wet

The most common sign that you’re overwatering your petunias is wilting. Typically, you’d expect to see a plant start wilting when you haven’t been watering it enough, but when your plant is wilting despite the soil being wet, it’s obvious that you’re overwatering it.

Petunias are subject to root and crown rot, a result of uneven watering. “Like pansies,” she says, “petunias must never be allowed to wilt, either from under- or overwatering. Once they wilt, it’s all over.” She advises providing good soil conditions, including preparation with organic materials and ample mulching.

Newly planted petunias need evenly moist soil for the first few weeks after planting, to establish a healthy root system. Once established, reduce watering to once every seven to 10 days. Provide 1 to 2 inches of water at each irrigation, which is enough water to moisten the top 6 to 8 inches of soil.

Maybe the most common (and easily fixable) is improper watering. Like lots of plants, petunias respond to a lack of water by wilting. Wilting petunia flowers can also be a sign of too much water. Always check the soil around your petunias before watering–if the soil is still damp, don’t water it.

You can revive an overwatered petunia if you act quickly. Remove the plant from its pot and stand it on a sheet of paper for a few days until the root ball becomes dry. Keep it out of direct sunlight while this is taking place. Repot into fresh potting soil after that, and do not water for three more days.

Petunias need at least 5 or 6 hours of good sunlight; they’ll perform even better when located in full sun all day. The more shade they receive, the fewer flowers they’ll produce.

Manure or coffee grounds can be added to the organic matter to replace the 10-10-10 balanced fertilizer for organic gardens. Compost tea or fish emulsion can be used in place of the water-soluble fertilizer.

To keep wave petunias blooming, they do need frequent watering. But too much watering can lead to soggy roots, and a weak plant. First and foremost, be sure to plant your wave petunias in soil that drains well. If you are placing in pots, containers or hanging baskets, use a lightweight, high quality potting mix.

Healthy petunias have a bushy growth habit, but they can become leggy and produce weak, overgrown stems during the growing season.

Pinching Wave

Petunias back encourages new growth and more branch- ing, and in return, more blooms! On long stems that look “leggy,” pinch the stem back 1 to 2 in. (2.5 to 8 cm), mak- ing sure to cut back past the desired branch length (new growth will fill in that space).

Wave petunias have a unique trailing growth habit and are highly prolific in their blooming. A regular petunia has an upright or bush growth habit. It may spread slightly, but will not drape down as dramatically as a Wave petunia.

Easy Wave is THE high-performance petunia, producing masses of bright color for containers and landscapes. With a spread of up to 36 inches, Easy Wave can quickly cover a large area in the garden or graciously cascade from baskets and containers.

Multiflora Petunia

Because of their mounding habit, multiflora petunias are a better choice for garden beds than grandifloras and they work very well in containers. There are also hybrids of grandiflora and multiflora petunias, which share qualities of both types.

Wave petunias are a favorite ground cover as they often spread 3-4 feet wide and bloom profusely.
