Having a rose, or other flowering plant, suddenly covered in aphids can be a a depressing sight. Fortunately, there are many ways to get rid of them and you may not have to use chemicals. This is a guide about getting rid of aphids.
I have aphids on my four o'clocks. I have tried soap mixed with water applied with a sprayer and have also used high-yield bug blaster Bifenthrin 2.4 mixed with soap. I cannot get rid of these aphids which are sucking the juice out of my plants which are producing seeds.
These are genetically modified half-and-half colored flowers; it took me 30 years to breed these. In the only pic of flower you can see the red and yellow on same flower, too early for them to open. Somebody please help!
Plants do not die from aphids invasion but I understand it is ugly to look at, specially when they invade beautiful flowers like yours. I never use any chemicals. I used two simple methods, killed them by hands on small plants and never grow one type of plant only, on one spot, always grow next to it, marigold and calendula which are protecting /repelling plants and nasturtium which will concentrate the aphids.
Hello again ! If you want to have new Four o'clock flowers (Mirabilis jalapata), you can collect the seeds, or dig one of its tubers. Grown from seeds or not, Mirabilis japata develops big tubers, which looks like black radishes, you can dig a few, and put them in a pot covered with sand during the cold season and put it back in soil when the temperature rises. It is a way to multiply the plant but also to keep the plant for the next season in places where winter is very hard. It is also necessary after a few years when the plant has developped too many tubers. Wear gloves when handling the tuber and keep seeds in a safe place they are toxic but you can keep them six years before replanting them.
Imagine my chagrin this year when for the first time ever I decided to try growing dill and woke up one morning wondering why the upper most tender portions of the plants, which were ready for harvest, were drooping heavily sideways. Upon closer inspection those portions were covered with aphids. Well, I certainly didn't want to use anything as a remedy that would be toxic so went to several internet sites to find a workable natural solution.
By the way, you will also want to check plants, both edible and ornamental, near the infested ones. I found those little buggers were also beginning to munch on my pepper plants! This is the solution that worked for me in just a couple of days by adjusting assorted homemade recipe ingredients that I came across on the web. First, in the case of my dill, I cut off the upper portions, which were most likely no longer fit to consume anyway, rinsed the remaining portions of the plants with a heavy stream of water and then heavily sprayed the plants and the surrounding soil with a water bottle using the following recipe:
Note: On the third and fourth days I did find a couple of renegade aphids on the stems and gave them a quick spray. When I checked each morning thereafter, those same little guys were brown and dead. I have absolutely no clue how or why but it gave me great satisfaction. ;-)

This is a guide about getting rid of aphids on roses. Aphids seem to like roses as much or more than we do.
There are insecticidal soaps on the market, however, I normally just take a small spray bottle with tepid water and a few drops of a mild detergent soap. It is much less expensive and I particularly like the "green" detergent soaps.
Controlling aphids takes spraying the leaves (both top and bottom) and also I spray the top of the soil. I do this every day (sometimes twice a day if the infestation is severe) for at least 3 to 5 days. It is important to keep checking the plant every day or two, since there may be a new hatch of aphids.
For plants that are outdoors having lady beetles is one of the best solutions. The lady beetle larvae just love to munch on the aphids.
As a side note, if you notice ants on a plant that has aphids you will find that the ants are actually "herding" the aphids. They love the sweet nectar that the aphids produce and they keep and protect the aphids as we would do with cattle, sheep, or goats. I mentioned this to a friend at our office who had ants and aphids on a plant and at first he thought I had totally lost my mind when I said the ants were herding their aphids. After I explained the relationship between the two, he seemed to understand and didn't question my sanity.

How do I get rid of aphids on my strawberries without using anything that would be harmful to our grandson and our Yorkie?

I assume that getting rid of aphids on strawberry plants is the same as getting rid of them on tomato plants. On my tomato plants I spray the underside of the leaves with a water hose, washing the aphids off the plants. They won't climb back up. I have read that tip in several different gardening books and it has worked every year for me for a lot of years.
Hello, I had that problem on our lemon tree. I bought ladybugs at Home Depot. I also noticed, when I had aphids, I also had ants. I believe the ants were eating the aphids too. Aphids are gone, and so are the ants. mvb
I'm with mvb. The most organic and safe method is to import some ladybugs. Besides your grandson will love them!
How do I kill infestations of aphids on my euonymus vine? They have manifested thickly on the stems as well.

For around $10 dollars you can buy about a 1000 ladybugs who will be more than happy to clean up those aphids and probably a few of the others as well. They will likely also set up a colony near by and be around for years.
But it sounds as though your plant is having trouble for some basic reason. Soil balance or nutrition not right, moisture? The plant isn't doing well there, otherwise it wouldn't be such a victim, poor thing. Might need some companion plants as well that repel those bugs. I think soapy water also helps repel aphids.
I use soap & water mixed in spray bottle,about half & half should do it, good luck.
Try Safer-soap, a non toxic mild soapy spray. Can also be applied by wiping down the plant with a sponge, but when finished, throw the sponge away so you don't infect other plants.
I read the answer re: milkweed for butterflies. I have a much harder time trying to grow them, from seed-starting, to trying to keep the sucking aphids off every day. Your other grower stated he had grown "tons" of milkweed in Spring Hill, FL.
I spray regularly with soapy water, but that's not getting rid of enough in my butterfly garden. I have sandy soil, water, open sun exposure. What am I doing wrong? Thanks so much.

Another method to get rid of aphids on plants is by going the biological way. You can introduce beneficial predators of aphids such as wasps, ladybird beetles and syrphid fly larvae. These natural predators are effective in controlling the aphids effectively. While using chemical pesticides, confine the application only to the infected parts, so as to conserve the population of these aphid enemies. Act quickly at the first sight of aphids and you will control them before causing serious damage to the plants.
I live in Spring Hill, Fl and have tons of tropical milkweed. I plant the seeds sporadically throughout the entire year and therefore I always have some in bloom with the exception of Jan & Feb. I start planting the new seeds from the year before pods in February. Yes, they do get aphids but the monarch butterflies still lay their eggs on the plants which gives me plenty of caterpillars and then soon after chrysalis and then the beautiful monarch butterflies.
As soon as a few plants get 6 inches high I plant more seeds in front of it so I have continuous plants. Most of the plants are in partial sun as they seem to do better than in the hot Florida sun that we have. Sometimes I use a very heavy spray of water (put your spray nozzle on the "jet" setting) on the aphids and they fall right off but I ignore them because the butterflies are still going to come. Yes, they look nasty but I have learned that it is worth the ugly look in order to have the beautiful butterflies. I do not want to spray any chemicals in my flower gardens as I want the bees and the butterflies to visit me and not get sick.
Phyllis: I forgot to mention that the only reason I grow tropical milkweed is that they are a host plant for the monarch butterflies. The caterpillars are going to totally strip off every leaf from the plant so I don't care about the aphids. After all of the leaves are gone and the caterpillars have climbed my wooden fence and are tucked snug in their chrysalis I cut the plant down to about 8 inches off the ground and they start to grow all over again. You can do the same thing since you are only about 2 hours from me. The monarch butterflies like my zinnias, verbena and vincas also but those are not host plants.
Is using soapy water on Hibiscus aphids as effective as purchasing a commercial product?

Hibiscus are my favorites so I have had lots of experience with aphids/Hibiscus. I don't know if soapy water is safe to use, but I know that insecticidal soaps are safe for Hibiscus, but after you use the soap, it will take a while for the plant to recover from the "treatment". I use a water hose (or sprayer in the kitchen sink for house plants), and no soap. I turn the water on low force and wash the aphids off the bottom of each leaf. Once washed to the soil, they will not climb back up and the plant will not need time to recover from soap or chemicals, so the blooms will keep on coming.
Should I give the hibiscus some fertilizer?
Yes, fertilize and you should get more and bigger blooms. Be sure you don't over-fertilize or you will get lots of lush green leaves and no blooms.
I need a home recipe to get rid of aphids on my cabbage.
By Judy from Waverly, OH
Washing the cabbage off with cold water from a garden hose will do the trick. Once on the ground, the aphids won't climb back up.
You need cabbage dust. Check garden supply shop, farm supply.
If buying ladybugs is not an option, I have been successful making a spray made from a boiled onion or garlic. Strain the juice and spray on the plants affected by aphids. This works for me. Tobacco juice is also effective.
