Grasp the main stem’s tip and pinch it between your forefinger and thumb to pinch petunias. The growing tips are delicate and are simple to remove. To cut off the plant’s tip, use scissors if you’d like. Just the top 1/3 inch or so should be removed. As the old flowers wilt, you should also pinch them off. Pinching wasted flowers just below the blossom is known as deadheading, because it helps the plant to produce additional flowers.

Before planting out, pinch out the developing tips of your plants several times in the early stages of growth to promote side shooting. This will produce plants with far more flowers and much more compact growth.
Some petunia cultivars may begin to appear a little worn out and straggly by the middle of August. Cut the entire display down by a third and provide a general purpose liquid feed to promote a second robust flush of blooms that will continue far into October. The plants will begin to bush out again in about a week, and fresh new blossoms will soon follow. The exhibit will return to full bloom in two weeks, just in time for your August Bank Holiday garden celebrations, with no signs that it has been clipped.
When starting petunias from seed, try to plant the seeds 10 to 12 weeks before the recommended planting date. Therefore, attempt to plant your seeds in the first week of March if you can normally start growing bedding plants in your location starting in the first week of June. Keep checking back as I go into greater information about petunia sowing before then.

How far back should petunias be pruned?
Petunias don’t respond well to harsh pruning, so use caution and only cut away long stems—especially those that are starting to look lanky. Never remove more than one-third of the plant’s stems by pruning.
When you prune, don’t completely remove the stem; simply take out enough to form the plant and get rid of any lanky growth.
Lots of Water
It’s no accident that the years with the most rain have also been the ones with the nicest petunias. Actually, because my plants have always been primarily watered organically by the rain, I’ve never really had to establish excellent plant-watering regimens. These are truly the first signs that my lovely petunias are about to lose their blooms because every now and then, like this year, we’ll have a dry spell. Even though, if I do so so myself, I’ve generally done a very good job of keeping up with the watering, the petunias simply need more. Petunias in pots may require more frequent watering than usual during these extremely hot and dry days. You should probably aim for twice daily for the best outcomes.
Deadheading
Petunias are undoubtedly one of the annuals that require the most frequent deadheading of the group in order to look their best during the summer. However, only removing the wasted blooms from leggy petunias won’t suffice to give them a fuller appearance. A faded flower is shown here adjacent to a fresh bud that will soon bloom.
A petunia’s complete seed pod must be removed from the plant in addition to the deadheading. This is the little green stub that is left over after a spent bloom is removed.
Look for the brown nubs as well since the seed pods will start to become brown as they grow a little older. You may simply snip off the entire length of stem that is below the tiny nub because it will also turn brown. Grab a pair of garden shears to make the task quicker and more sanitary because the nubs and stems don’t come off as easily as the spent blooms do.
Pruning
Early on in my problems with petunias, I was unaware of the fact that petunias actually require regular trimming to be full and more compact. If you don’t trim your petunias, you’ll frequently get lanky petunias, which are long, empty stalks with one or two flowers at the very end.
Every few weeks, you should trim your petunias by cutting off the top 1/4 to 1/2 of each stem. Feel free to prune only a few of the longest stems one week, and a few others the next week. This can seem like a difficult task, especially when everything is in full bloom. In this manner, you’ll have stems that are constantly regenerating and others that are in full bloom.
Try to leave a few leaves on each stem when pruning petunias, and cut slightly above the “node,” or the point where two leaves meet the stem.
As you can see, I did quite a bit of cutting down, but I’m left with a really healthy-looking tiny plant full of fresh new leaves and very little of the crispy brown leaves and stalks that were covering the previous plant and giving it a sad appearance.
How do you take care of petunias in a hanging basket?
Hanging baskets will require more regular maintenance because water and nutrients leak out of them more quickly than for plants in the ground.
How do you keep petunia baskets blooming?
Petunias consume a lot of food. To encourage additional blooms, add a water-soluble fertilizer with a higher concentration of phosphorus and potassium to the slow-release fertilizer you applied when you were planting. Many contemporary hybrids are self-cleaning, unlike older kinds that need deadheading for ongoing flowering.
How many petunias are in one hanging basket?
It depends on the size of the basket and the plants’ mature size. Use four to six starter plants in 4-inch pots for a 12 to 14-inch basket.
How often to water a petunia hanging basket?
The best water for petunias is constant water. Checking hanging baskets periodically is necessary since they dry out rapidly. It’s time to water if the soil feels dry 1-2 inches down. This can include watering once or twice each day during warm weather. Reduce water use and avoid letting the soil become moist in cooler temperatures.
How do leggy petunias appear?
Petunias that are leggy (Petuniaatkinsiana) appear to have all of their flowers and leaves at the end of a protracted, barren stalk. The resulting bare space is a real eyesore unless additional plants have been thoughtfully added around or with your petunias. Learn how to control leggy petunias this season and how to change your petunia maintenance schedule to stop the next batch from becoming leggy as well.
Do I need to trim back the lanky petunias?
Petunia legginess can be avoided with diligence and consideration. To begin with, remember to keep your petunias moist. You might need to water petunias every day if you have them in a smaller container or basket. Make it a routine to check their moisture level each morning and to give them plenty of water to drink. You might need to water your petunias every three to five days if they are planted in the ground.
We are all aware that petunias bloom most profusely when the spent flowers are frequently deadheaded. But just plucking the petals is insufficient. If you want to learn how to stop petunias from growing too long, you must also remove the seed. At the base of what appears to be five slender green leaves arranged in a star-like configuration, the seed pod resembles a little green (or tan, if it is mature) chocolate chip. Cut or remove this blossom by snipping it.
Have you ever thought, “How can I get my petunias to grow bigger?” You must regularly trim the branches back by a quarter or a half to prevent lanky petunias. Since your petunia plant might be in full flower when you do this, it might be challenging. All of the branches can be pruned at once. In a few weeks, you will have a full, compact blooming petunia plant.
You can also prune just a few of the branches that are dispersed uniformly across the plant (by 1/4 or 1/2). Two weeks later, you can prune the remaining branches after those branches recover and rebloom. Maintain this cycle throughout the growing season to get the benefits of a full appearance and an abundance of beautiful petunia flowers.
When ought one to pinch out?
The phrase “pinching out” may have been used in relation to your dahlia or tomato harvest. Although it is a widespread practice among gardeners, careful consideration is required to use this technique efficiently.
Pinch out, in its most basic form, is a technique for pruning young plants to promote branching that will eventually bear more fruit or flowers, increasing the output. The plant will physically branch out to produce new stems and branches if the uppermost portion of the stem is practically pinched off just above leaf nodes or buds.
Pinching has a few additional advantages as well. First off, pinching stops your plants from growing excessively long and lanky. You can build a stronger central stem by promoting growth in the lower branches. Second, regular pinching will keep plants from coming to seed too early on those plants that are primarily grown for leaves (like herbs), ensuring that the foliage remains lush and full. Coleus and other plants with ornamental leaves can be plucked to get the same effect.
How to pinch out
Quick Advice for Cutting Back:
- Don’t hurt the leaf nodes that are underneath the pinching point. The best way to pinch is with your fingertips or a pair of sharp scissors or snips.
- Stop pinching too soon. Wait until the plant has grown strong enough to survive pruning and at the right height.
- Recognize when to stop. The longer you have to wait for flowers or fruits, the more you are pinching out. Overpinching can also result in highly bushy plants with crowded blooms.
The early growth can be readily removed by pinching it between your fingers because it is so delicate, but if you like, you can also use snips. Regardless of the technique you employ, avoid damaging the leaf nodes because doing so will make it difficult for the plant to develop new branches. If desired, you can repeat this procedure on the new branches as well, but avoid developing a habit that causes over-pruning. To prevent illness from spreading to the stem, be sure to pinch just below the leaf nodes.
Once the plant has taken on the correct shape, stop pinching it out and let it flower naturally. The blossoming will be postponed while you are working on pinching out, but this is done so that the plant will be fuller and produce flowers and fruits later in the season.
Young plants are the best candidates for pinching out because adult plants may suffer health effects. When to pinch out a plant depends on the type of plant, therefore it is better to verify if you’re unsure. Some plants may experience limited growth as a result of early pruning, and young plants may become destitute if too much foliage is removed; the plant needs enough foliage to carry out photosynthesis and flourish.
The plants did actually become bushier last year after I started cutting off my dahlias far too early, but the stems were stunted and the blooms were so close together that many pests opted to make a home there. I spent a lot of time attempting to correct my error, but some of the petals never fully opened up. The lesson of the story is to know when to quit pinching and not to pinch too soon.
Pinching Tomatoes, Dahlias & Basil
Plant species that typically only produce one main stem are the ones that are typically pinched. Basil, dahlias, and cordon tomatoes are some of the favorites of gardeners that are frequently snipped. See more instances of plants that can benefit from pinching out by scrolling down. The following advice is for the favorites:
Pinching Out Tomatoes
Tomato types that are indeterminate respond to pinching quite well. These tomato varieties include “Gardener’s Delight,” “Sungold,” “Beefsteak,” and “Sweet Million.”
Once your tomatoes have at least six sets of genuine leaves, you can begin pinching them out. Instead of pinching from the top, you want to prune the side shoots because you want the main stem to continue growing for a considerable amount of time. (Insert canes to provide assistance as they climb vertically.)
Tomato sideshoots are those that emerge at a 45-degree angle from the main stem and branches. The plant will be forced to focus its energy on the main stems and fruits if you pinch out the sideshoots.
You can stop the main stem from growing after your cordon tomato plants have grown to their full height by pinching off the top below the highest flowers. To achieve the healthiest harvests, it is advised to have no more than seven trusses (stalks with several flowers that will develop into fruit) on the plant.
Additionally, now that you know how, it’s crucial to refrain from pinching out all of your plants. Pinch outs are only beneficial to some plants while being actively harmful to others. Do not pinch back your bush tomatoes since determined tomatoes (also known as bush tomatoes) will yield fewer fruits if you do.
Pinching out Dahlias
Before you start pinching, wait until the main stem is about 12 tall and has at least four sets of leaves. A dahlia plant will become squat and densely bushy if the stem is pinched out while it is still short. When the flowers begin to bloom, they will swarm one another, which can invite pests and diseases due to poor air circulation. It will be more difficult to notice the lovely blooms as well.
Pinch out the topmost tip of the stems right above a group of leaves. The remainder of the procedure is same. Cutting and deadheading the flowers after they bloom also encourages healthy growth and additional blossoms.
Pinching out Basil (and some general advice on trimming herbs)
Basil grows bushy and lush with plenty to use in your cooking and responds particularly well to pinching back because it typically grows one central stem.
Always trim the stem down to just above the leaf nodes when harvesting basil or any other herb using the pinching technique. Avoid the urge to simply pluck the leaves off. The plant’s resources will be drained by bare stalks. Cutting the stem encourages root development as well.
For new gardeners learning how to pinch, herbs are a great variety of plants. Regular trimming of herb plants is the greatest technique to promote bushy growth and avoid legginess. Additionally, any branches that are cut become your harvest for cooking.

When Not to Pinch
Not all plants respond well to being squeezed back, and excessive pinching can be harmful to some plants.
Plants that naturally become bushy in growth do not require pruning. All you really do is delay normal growth, which could lead to a lower yield. Tumbling tomatoes, for instance, are a good illustration of determinate tomatoes.
Pinch-out techniques are ineffective for monocotyledons and may even cause the plant’s death. This is due to the unique ways in which these plants store their energies and the fact that pinching removes the developing tip. Alliums, grasses, and the majority of flowering bulbs including tulips, daffodils, and lilies are examples of monocots. Monocots typically rebound from pruning and sent up a new stem to replace the one that was removed. However, you will only receive one; no bushy growth. We must cut the stem of chives, a monocot allium, in order to harvest it, and then we must wait for the stem to grow back. The plant keeps expanding, but the only option to increase the output is to either wait for the bulb to generate offsets that develop into separate plants or to sow new seeds, of course.
NB: For regulated types of development, pinching out can be employed to purposefully limit growth in some plants. For instance, young sunflowers can be pinched to produce shorter stems for cut flowers. However, in most circumstances, this is not advised.
Avoid pinching the following plants:
- Campanula
- Cockscomb
- Delphinium
- Sunflowers
- Larkspur
- Container Tomatoes
- Dill
