Does A Penny In Water Help Flowers?


As a flower gardening expert, I am here to provide you with all the knowledge that you need to know about how a penny in water can help keep your flowers alive longer.

Read on as I explain the benefits of using pennies in water and other useful tips for keeping your flowers healthy and vibrant for as long as possible!

What is a Penny in Water?

A penny in water is an old-fashioned gardening trick that has been used for many years to help keep flowers alive longer and prevent wilting or discoloration of petals.

It involves dropping a copper penny into the vase containing the flowers, which then provides the stems with essential nutrients and minerals that help them stay hydrated and healthy for longer periods of time.

The rule of thumb is usually one penny per quart of water, although this can vary depending on the type of flower or vase used.

How Does it Help Flowers?

The reason pennies are considered a smart way to keep flowers alive longer is because copper is a fungicide, so it naturally kills off those pesky bacteria and fungi that are trying to camp out in your flowers’ vase and shorten the life span of your stems.

Copper also helps retain moisture around the stems which helps them stay hydrated for longer periods of time, prevents wilting, and helps keep petals vibrant and colorful for longer periods of time as well!

What is Copper and its Benefits?

Copper is an essential mineral that helps plants grow healthy and strong by providing essential trace elements that are not found naturally in soil or water sources.

It also helps plant cells absorb more nutrients from their environment while helping them fight off disease-causing organisms like bacteria, fungi, viruses, nematodes, molds, mildews, etc.,

which can be damaging to plants if not properly controlled or treated with copper-based fungicides or other preventative measures such as copper-infused soil additives or fertilizers!

Copper as Fungicide

Copper has also been proven to be one of the most effective fungicides available on the market today due to its ability to kill off certain types of fungi that tend to inhabit moist environments such as flower vases filled with water, thus it is often used by professional flower growers who need long lasting results from their blooms without having to constantly reapply fungicides every few weeks or months!

Other Benefits of Copper to Flowers

Not only does copper help protect flowers from disease-causing organisms, but it also helps improve their overall health by providing essential trace elements they need while preventing nutrient deficiency symptoms such as yellowing leaves or stunted growth that can occur over time without proper nutrition or treatment!

Additionally, copper can even help increase flower lifespan by helping them resist extreme temperatures both hot and cold which can cause petal discoloration or wilting if left untreated!

How To Use A Penny In Water Effectively

Using pennies in water effectively requires some planning ahead so you don’t end up with too much copper present which could actually be detrimental instead of beneficial!

A good rule of thumb is one penny per quart (or liter) of water so make sure you plan ahead when filling your vases so you don’t add too many pennies! Additionally, make sure you clean out any old pennies after every use since they can become contaminated over time if left uncleaned!

Disadvantages Of Using Pennies In Water

While using pennies in water can have its benefits there are some potential drawbacks associated with this method as well such as potential toxicity if too many pennies are used at once (which could lead to plant death) or possible contamination if they aren’t cleaned after every use (which could cause plant diseases).

Additionally, some people may find the idea of metal coins sitting at the bottom of their flower vases unappealing so it’s important to consider these potential disadvantages before deciding whether this method will work for you!

Alternatives To Pennies In Water

If you’re looking for alternatives to using pennies in water there are several other options available such as adding crushed eggshells around plants’ roots which provide essential calcium needed for healthy growth, adding Epsom salts which contain magnesium sulfate, adding vinegar which can help kill off certain fungi, adding sugar which provides energy for photosynthesis, adding ground coffee which contains nitrogen needed for strong stems, or even adding soil additives such as iron sulfate which also provides essential trace elements needed by plants during their growth cycle!

Final Tips For Keeping Flowers Alive Longer

Finally here are some additional tips for keeping your flowers alive longer such as making sure they have enough sunlight each day, deadheading spent blooms regularly, cutting stems at an angle before placing them into a vase filled with fresh room temperature water, changing out old stagnant water every few days, fertilizing monthly during growing season, avoiding overwatering (which can lead to root rot), avoiding placing flowers near heat sources (which can cause sunburn), removing foliage below water line (which harbors bacteria), misting petals frequently (which prevents wilting), and more!


In conclusion, using a penny in your flower vase can be an effective way to keep your blooms alive longer if done correctly by following all necessary precautions mentioned above along with additional tips for keeping your flowers healthy over time such as providing adequate sunlight exposure each day, deadheading spent blooms regularly, changing out old stagnant water regularly etcetera. With just these simple steps you will be able to enjoy beautiful vibrant bouquets far longer than normal!
