Often grown as annuals, Petunias are one of the most popular flowers. They are tender perennials in Zones 9 to 11.
Petunias are divided into two different groups:
- Grandiflora petunias have very large flowers and are best grown in containers or hanging baskets (because they are more susceptible to rain damage).
- Multiflora petunias have smaller, but more abundant flowers and are ideal for summer bedding or in a mixed border (because they are more tolerant to wet weather).

If your petunia flowers are
If your petunia flowers are curling, it probably means a fungus is getting started. Water less, avoid overhead watering and water only at the soil level, increase air circulation, and spray with an all-purpose fungicide.

My petunias stay small and they look horrible they have good soil and I fertilize them and Water them and they just don't grow but they want to bloom and I do cut the stems off
It sounds like you are on top
It sounds like you are on top of the watering situation. Hopefully, they are getting enough sun. Try cutting them back, which will encourage bushier growth. Petunias are heavy feeders and grow best with a soil pH between 5.5 and 5.8. With a higher soil pH, petunias begin to suffer from iron deficiency. Try fertilizing with a fertilizer rich in iron.
Hi all petunia lovers, I
Hi all petunia lovers,
I planed my wave petunia (which said it can spead out 3-4 feet) for 2 months and can't wait to see it spill down from my deck but it has not. When I first grow i headdead them and they bloom like crazy but they don't spill down. My husband said since I headdead them the plants focus on producing more flower and won't grow long, is it true?
Thanks!
My petunias are in a hanging
My petunias are in a hanging basket and are in full bloom. The flowers are fine but I've noticed lately the leaves are turning yellow, especially at the base of the container. They weren't doing this for the first month or so, but it seems to be getting worse now that the weather is warmer. Any suggestions? Thanks.
Have you given your plants
Have you given your plants any fertilizer? Petunias are heavy feeders and grow best with a soil pH between 5.5 and 5.8. With a higher soil pH, petunias begin to suffer from iron deficiency. Try fertilizing with a fertilizer rich in iron.
I have multiple colors and
I have multiple colors and types of petunias in about 15 pots/window boxes that I purchased from a hardware store. Once I got them home, I quickly saw that the flowers were being eaten by something. I do not find any evidence of bugs or caterpillars, but have been spraying the plants daily with Safer caterpillar killer.
I also deadhead the flowers that are affected, but I am not seeing an improvement. What is going on with my plants and how can I treat it?
Hi Debbie, You probably have
Hi Debbie,
You probably have some night visitors. Go out after dark and check for earwigs or slugs. They usually hide during the daytime and come out when it's dark.
Some of the branches in my
Some of the branches in my Purple Wave petunia are sprouting blooms that are a mottled green and purple, almost tie-dyed looking. Is that normal, or a sign of a mutation? Or maybe even a deficiency?
Hi, Sara: Unfortunately, you
Hi, Sara: Unfortunately, you are describing a classic case of tobacco mosaic virus in petunias. This is usually caused by the plants being handled/touched by someone who uses tobacco products somewhere in the supply chain, whether grower, greenhouse, or garden. In any event, there is no cure other than to very carefully (so as not to contaminate elsewhere) and thoroughly remove/destroy the infected plants, soil, and anything else nearby. Sorry!
I am attempting to grow
I am attempting to grow petunias for my wedding in August. I bought some beautiful hanging baskets at mother's day because they were the perfect color. They have gotten very large and I would like to continue to keep them healthy. Does anyone have any advice on how to do this? Will they even stay alive that long?
I'm not a gardening expert in
I'm not a gardening expert in any way, but my own petunia hanging basket has probably tripled in size since I bought it. I had good luck with splitting up some of the plants and re-potting them so they could continue to grow. We put half of them back in the basket and the other half in a big pot and everyone seems to be adjusting well to the move. I'm not sure how long they will last, though. You could try trimming them back if they're too big/long and they should continue to produce new blooms. Good luck and congratulations!
Fertilize your plants monthly
Fertilize your plants monthly to ensure good growth. Also, remove faded or dead flowers to prolong blooming.
I have over wintered the same
I have over wintered the same hanging petunias for the last two years. I did lose a couple of plants the first time around, possibly due to over crowding. I just started bringing the basket in at night, when the temps outside got colder. Once day time temps got cold, they just stayed inside in my sunniest window. I water at least once a week and give them a bit of plant food when I think of it. The plants will bloom less or not at all during the winter, but once the days lengthen flowering resumes.
I just transplanted some
I just transplanted some petunias and begonias into the same pot about two months ago. They seem to be growing very rapidly and are loving the weather. I was just wondering if I needed to take the begonias out soon and if they would be taken over by the petunias???
If you like the combination
If you like the combination of petunias and begonias you can move them all to a bigger pot and keep them together. The begonia will probably get bigger and start shading the petunias in the smaller pot.

How do you know if plant needs bigger pot
If your petunia needs water
If your petunia needs water more frequently than before, if it seems to be top heavy in its pot, or if its roots are growing out from drainage holes in the bottom, your petunia may need to be repotted in a larger pot.
When first planted should you
When first planted should you dead head all the flowers? That's what my Mother used to tell me. Thanks.
Hi, Barbara: Mother was
Hi, Barbara: Mother was always right. Especially around Mother's Day. Uh, actually, come to think of it, Mother was always right all the time. But anyway: Normally, you deadhead the spent blossoms to prevent your plants from becoming scraggly as they put their energy into forming seed pods. When first planting, it's not necessary to deadhead all of the flowers, but what your Mother knew was that doing so would indeed help the plants get off to a good start by focusing their energy on growing. Everything else being equal, they might make out fine without premature deadheading, but perhaps they would do a little better with. Up to you!
I plant petunia in my ceramic
I plant petunia in my ceramic window "boxes", which are about 2ft long, and not wood. They do well in an average potting soil being watered about once every 4 days here in Texas. Any flowers or plants in hot, arid areas need to be watered more often than plants that are in the ground. The heat causes the moisture to evaporate much quicker from pots and planter boxes.
My mother grew petunias
My mother grew petunias successfully and told me to pinch the back the wilted/dead flowers to encourage blooms. Was she correct? If so, do I pinch ony the dead blossom or or behind it, which would include the calyx and so preclude seeds from
forming. She planted anew each spring and not from seeds. She has gone now and you would know best anyway. Advice?
Pinch or cut them back to the
Pinch or cut them back to the first set of leaves or almost to the branch the flower stem came from, which ever is first. If the plants are young pinch back some of the growth tips, it will make the plant grow fuller instead of getting leggy. They usually start getting leggy is you don't deadhead (cut spent flowers off).
I love to plan petunia in the
I love to plan petunia in the window box on my deck. What kind of petunia should I choose to make it trailling cascading down from my deck few feet long and fully bloom?
Thank you.
Surfinias are the best for
Surfinias are the best for hanging baskets and for trailing .4plugs should be enough for a 12 inch basket.
Thank you so much Lesley, i
Thank you so much Lesley, i can't wait to see them blooming. It's officially spring but the temp here still under 30F at night.
I love growing petunias of
I love growing petunias of differen colors. they normally grow and bloom beautifully. I have bought new seedlings and planted them into the ground. prior to this i prepared the soil with a good classic fertiliser. however, much to my dismay i found that after planting there was bugs in the soil, so i treated this with a solution of rosecare3, and now i find that all the leaves have been eaten. I then mixed a mixture of classic plant food and sprayed them with it. Please help, what do i do.
Insecticidal soap, neem oil
Insecticidal soap, neem oil or horticultural oils will rid the petunias of many insect pests. You can make your own insecticidal soap or buy it at a garden center. Neem and other oils can be found at garden centers.
