Trimming petunias is an operation that will prolong the blooming period of the plant at least with one month. It’s a distinct operation of pruning that is made in the spring. So, you better put your gloves on, and start trimming your petunias if you want to enjoy their fragrance flowers all summer (why not fall) long.

Petunias bloom all summer long and must be groomed permanently. This means that as soon as the flowers are dried and gone, they must be removed so that they don’t form seed capsules. If this happens, the number of flowers that will appear will be smaller and smaller.

Even if you do this periodically, the shoots grow and at one point they become unsightly and make fewer buds. It’s time to intervene to stimulate a new bloom.

Plant care
Shorten well the plant, by cutting the stems in half or you can leave even a third part of them. Cut over a knot where the leaves are caught. For a short period of time they will be unsightly, but from the place where you cut will soon appear new shoots and new flowers.

July is the month in which you can do these operations. Also, you should keep in mind that in the morning it’s the best time to trim your petunias, because the temperatures are not so high and the risk of dehydration is lower. Always use a well-sharpened and clean pliers. Carefully clean Petunia so that no seed-capsules or wilted flowers remain.

Once you have cut the plant, it will go through a period of stress and it’s important not to aggravate it. So be careful to water in time, that means daily watering, and on hot days, even twice a day, so that the substrate won’t dry out. In the absence of a sufficient amount of water, the shoots will soften and the leaves will dry.
After a week from trimming, you can add a small amount of fertilization, not to stress the plant.
