What are the most common problems with growing petunias?
The most common problem with growing petunias is thrips. Thrips feed on the leaves of the plant and cause them to turn yellow and fall off. They reproduce quickly and spread rapidly throughout your garden. You can control these insects by spraying pesticides on your plants or using insecticidal soaps on your hands before handling your plants. Another pest that causes damage to petunias is aphids. Aphids feed on the foliage of the petunia and cause it to wilt and die. You can control these pests by applying insecticides or using sprays of water. Finally, another pest that attacks petunias is scale insects such as scales and whiteflies (also called leaf miners). These insects live under the soil surface and feed on your plants’ roots. They will eventually kill your plants if left unchecked. To control these pests you can use insecticides or use mechanical methods like digging up your plants.
How do I prevent my petunias from becoming infested with pests?
There are several ways to keep your plants free of pests:
1) Use organic fertilizers.
2) Do not over water your plants.
3) Prune away any dead branches when they become too thick.
4) Keep weeds away from your plants.
5) Prevent pets and birds from eating your plants.
6) Check your plants often for signs of pests and diseased foliage.
7) Hand pick any pests off of your plants and dispose of them.
8) Put screens over your plants to prevent birds from eating them.
9) Plant your flower beds in such a way that they drain well (with gravel or sand).
10) Do not plant your petunias where tomatoes, potatoes, eggplants, or peppers were planted the year before. 11) Pick off and dispose of any diseased foliage as soon as you notice it.
What are some signs that my petunias have a disease?
Some common diseases that affect petunias are:
1) Petal blight.
This disease causes your petunia’s petals to turn yellow and fall off.
2) Leaf spots.
These cause dark spots to form on the leaves of your petunia.
3) Crown rot.
This causes the stems of your plants to become mushy and weak.
4) Collar rot.
This causes the plant’s collar (the area where the leaves join the stem) to become brown and mushy.
This causes your petunias to become covered in a fuzzy white substance.
What are some signs that my petunias are infested with bugs?
Some common insects that attack petunias are:
These suck the life out of your plants by feeding on them with their razor-like mouths.
These destroy your plants by feeding on them and sometimes even eating the petals.
3) Scale insects.
These insects form a protective shell around themselves called a shell which they hide under on your plants.
What is the best way to get rid of pests?
The best way to get rid of pests is to use pesticides (insecticides, fungicides, etc). You can also use organic methods to get rid of the pests such as putting crushed garlic on the soil around your plants or using natural sprays that can be purchased at your local garden supply store.
What other factors can cause my petunias to die?
Some other factors that might cause your plant to die are:
1) Lack of water.
2) Lack of sunlight.
3) Poor quality soil (or too much fertilizer).
4) Certain diseases.
5) Certain insects.
6) Certain physical hazards (such as extreme temperature changes or being stepped on).

What is the best way to get rid of bugs on my petunias?
The best way to get rid of bugs on your petunias is to use beneficial insects to eat the harmful ones. You can then use pesticides as a last resort.
Why do some of my petunias have long stems while others are just little orbs at the base?
The long stemmed petunias are more mature and blossoming, while the smaller ones are simply growing.
What is the best way to deal with slugs and snails?
The best way to deal with slugs and snails is to use beer. Get a shallow bowl and fill it 3/4 of the way with beer. Place it where you want to keep the slugs and snails out of. The snails and slugs are attracted to the beer, they crawl in and can’t climb back out.
We’ve had an infestation of whiteflies, what can I do?
The first thing you need to do is to get rid of the infestation. Use the sticky cards or yellow traps to collect them. Next, spray a light coating of oil over the top of your plant. This will suffocate the whiteflies. After spraying, be sure to wash it off with water so that your plant doesn’t suffer any damage. To prevent future infestations, simply spray your plants with the oil every few days.
What is the best way to rid my petunias of aphids?
The best way to get rid of aphids is to spray your petunias with an insecticidal soap. This will not harm your plant, but will do a great job of controlling the aphids. However, make sure you remove any infested leaves or flower buds before spraying.
How do I start my petunias from seeds?
The first thing you will need to do is collect some petunia seeds. To do this, simply go through the petunias and choose the best flowers. Cut the heads off and place them in a paper bag. After a couple of days shake the bag lightly to loosen the petals and then take them out to air dry for about a week. Once they are completely dry, put them in a container with a lid (such as a mayonnaise jar). Place this container in a cool, dry place and forget about it until next spring. Next spring, when you want to plant your new seeds, put the lid on the container and shake it lightly to distribute the seed evenly. Then take a piece of newspaper or paper bag (so it doesn’t tear) and spread the seed over it. You will see the little petunias sticking up through the seeds. Now take that piece of paper and put it under a clear, plastic sheet (such as a large bag or a shower curtain). Set this somewhere in indirect sunlight. The seeds need light to germinate. Keep checking daily and as soon as you see the seedlings poking up, take the sheet outside and gently blow on them to remove the seeds from the paper. Then put the paper with the rest of your used seeds and start over again!
You have several options for potting your petunias. You can use a one gallon plastic pot or a three gallon plastic pot .
