Should I cut new petunias back?

When I bought some petunias in a 6 pack, they were very leggy. Do I cut them back right away or wait till they get established?

  • It would help them grow better if you cut them back. It is best to plant flowers that are not blooming so that the plant will keep energy going to the roots to establish the plant rather than pushing its energy to blooms. And fertilize! they love fertilizer! Hope this helps! happy gardening!

    Ok, I just didn't know if I should do it before they got roots established in the pot I am putting them in. I thought maybe they would have to take hold there before cutting them back. How far would you cut them back?

    I usually pinch the flowers off, which allows the energy to into rooting well. I fertilize with Miracle Grow, or another, and new flowers will pop up shortly:) Pinch the stems, but keep the leaves, as this is how it gets energy.

      @Kathleen Goodness, gurl. You need to be using a non-chemical fertilizer. Miracle Grow makes the plants grow alright, but kills the microorganisms in the soil, including the worms. Healthy soil helps make for much better, bigger plants that bloom longer and are far more resistant to insect pests and diseases.

    First of all for me it is hard to cut them back,because we want flowers.But it is the best thing to do.It will force the plant to bush out making a fuller plant and more blooms.It also will not take to long for the plant(petunias) to start flowering again.I for my own reason,s will pot up my flowers then after a couple days cut them back.That way if feel i got to enjoy them first. Elaine i will also cut back my flowers a week or two before a dinner party so they are in full bloom when the day come,s. And most gardeners i know beam when told what a pretty yard and flowers they have.If they don,t they must have a gardener.

    I know that cutting them back helps the plant but as I said, I was not sure to cut them back until they got established in their new pot. BTW I am familiar with your town. I used to live in Cedar Falls!
    • @Elaine Simmons to answer that question-a plant gets better established when you cut them back. a plant will establish and grow faster if it doesn't send its energy to blooms instead of roots. You want your plants to send energy to its roots to get established and once established, the blooms will come! I like to use fish emulsion in my watering cans with rain barrel water. I believe, and this may sound weird, but plants know the difference between rain and city water and will grow much better with rain water. Fish emulsion can be found for less than $10. Happy gardening!

    Elaine i use to live in waterloo so i know cedar falls well. Just cut them back it will not hurt them. Even though you just planted them. Being your in AZ now maybe move to a area that is not to hot till they get going. Happy Gardening in AZ

    Can you ladies clarify what "cutting back" means? I know about deadheading blooms, but when do you cut them? When you take them out of the packs? do you mean to cut the actual stem down to the dirt? I'm pretty much a novice but love planting! Would you suggest the same for wave petunias as well? Thanks!!!
    • Wave petunias do not need deadheading. Deadheading means snipping off the old blooms of with either your fingernails, scissors or pruners. Cutting back means cutting of the dead looKing stems or branches on a plant down to where the leaves are healthy.

    Thanks Dee!

    Michelle What i mean by cutting back is .Take the flowers out of the packet if there is blooms on them plant and then cut the blooms off,if no blooms then just plant and leave be.How ever during the summer plants tend to get leggy that means the plant blooms more so at the end instead of all over. cut back a inch or two. I must point out that i am talking about annuals.Elaine was talking about (petunias).There is a petunia that has smaller blooms on it and will not need deadheaded,I will when i think about it.This will always do better when cut back when leggy.

    Dee, you are thinking of "Million Bells" or "Calibrachoa. I knew those didn't need deadheading.
