It’s happened to all of us – you water your houseplants with tap water, only to find they have yellowing leaves or stunted growth. But did you know boiled tap water could be the answer to better-hydrated and healthier plants? Many people are unaware of the benefits of boiling tap water for them and their green friends.
In this blog post, we’ll explore the advantages of using pre-boiled tap water when watering your plants – including improved plant health and reduced risks from unseen minerals.
Are chemicals in tap water bad for your plants?
Tap water can contain a number of chemical compounds, including minerals, chlorine and fluoride. Although it is necessary for human consumption, these chemicals can be bad for plants when consumed in excess. While minerals are usually not harmful to plant life in small quantities, chlorine and fluoride can potentially damage roots and leaves, leading to the browning or yellowing of foliage and stunted growth.
Watering your plants with tap water may lead to visible signs of damage within a few months. The best way to hydrate vegetables, flowers and other plants is to collect rainwater or use safe drinking water stored in a sealed container. That way, you can avoid potential harm from tap water chemicals while ensuring that your plants receive the nutrients they need to thrive.
Does boiling water purify it?
Boiling water effectively removes most of the chemicals and contaminants in a water source, making it very useful for those growing plants or crops. Boiling the water will denature some compounds and make them inert. This purifying process is known as distillation and involves boiling contaminated or polluted water until it evaporates, leaving behind all particulates in the liquid.
After evaporation, a cleaner form of water can be collected at the end. Boiled water also kills pathogens which pose a health risk to humans or animals if consumed. Ultimately, boiling already distilled water increases its purity even more and creates a safe environment for your plants to thrive in.
Why you should never pour hot boiling water directly onto your plants
Planting a garden is rewarding and enjoyable. However, some things to be aware of if you want your garden to thrive. Hot boiling water can harm many plants because it can burn the roots, leaves and other parts of the plant. It can cause major tissue damage and, in some cases, death to the plant.
To keep your plants healthy, always test the temperature of your water before pouring it directly onto any plants or into their soil. Lukewarm water is generally safest for delicate petals and foliage. Additionally, ensure not to overwater when watering, which can lead to root rot. The best way to give your plants what they need is by finding a balance between these steps so that they grow happy and healthy!
Is cooled water that was boiled better for your plants?
When it comes to watering plants, opinions on what type of water is best vary greatly. Some gardeners swear by fresh rainwater, while others prefer tap. But one thing many have come to agree on is the benefit of cooled boiled water for plants – especially when growing more delicate species in your garden. Removing any impurities from the water through boiling and allowing it to cool a bit before use helps maintain the perfect temperature and pH level for your plant’s health.
Not to mention, cooled boiled water can also help prevent initial shock from extra hot (or cold) water during an otherwise rare dry spell. And why cause any extra stress to your lovely foliage if you don’t have to? So if you’re looking for one of the best ways to care for your garden, turn to cooled boiled water as an effective and simple solution.
Does it make a difference if it’s a potted plant?
When watering our plants, the type of water you choose can make a huge difference – especially if you’re growing potted plants. Plants in pots are particularly sensitive to certain types of water with high concentrations of chemicals like chlorine and fluoride, both of which can be found in tap water. Boiled and cooled water is often recommended for houseplants and garden plants, as it is free of most pollutants. Boiled water can also help reduce the build-up of salt in the soil, naturally occurring with regular watering. So if you’re looking for the best way to ensure your potted plants are healthy, cooled boiled water is definitely worth considering!
Plants that are sensitive to tap water
Calathea and Maranta plants are known for their vibrant foliage, adding a splash of colour to any area. However, they can also be quite delicate, often requiring special care due to their sensitivity to tap water. Tap water contains minerals and pollutants that can be hard on Calathea or Maranta – leading to unhealthy plants or even death.
Rainwater or water that has been filtered prior should always be used on your Calathea, Maranta and Ctenanthe in order to give your plant the best chance of survival. Outdoor plants that are sensitive to tap water chemicals include certain types of ferns, hydrangeas, gardenias and roses.
Soft vs hard water
Water hardness, or the degree of water’s mineral content, is determined by a measurement known as grains per gallon of calcium carbonate. Soft water is treated water with most or all of its minerals removed through ion exchange or reverse osmosis. It’s called “soft” because it doesn’t contain any calcium or magnesium ions responsible for making the water harder. Soft water is often used in homes because it can reduce staining on dishes and clothes and help keep pipes from clogging up with mineral deposits over time. Additionally, soft water does not leave behind soap scum when it comes in contact with soaps and detergents.
Hard water, on the other hand, is untreated and contains high levels of calcium and magnesium ions that give it its distinct “hard” properties. While hard water may not be great for laundry purposes or keeping pipes clean, it contains beneficial minerals like calcium and magnesium that can benefit your health if consumed in moderation.
Why rainwater is the best for your plants
Rainwater contains naturally occurring minerals and trace elements essential for healthy plant growth. Not only is rainwater chemical free and free of chlorine, but it is also highly oxygenated and at the same temperature as the plants’ natural environment – this helps to create a favourable condition for root microbes to strengthen the plants’ hold in the soil.
Rainwater is especially great for vegetable gardens that require specific nutrients, as it allows each garden to receive proper nourishment and hydration without risking sacrificing the pH balance of their soil. Ultimately, choosing rainwater for your plants ensures your garden gets all the benefits without any potentially damaging chemicals.
Water is essential for life and plays a hugely important role in the health of your plants. Understanding the different types of water available – tap water, distilled water, purified water, soft water and hard water – and their benefits will help you make informed decisions on which is best for your particular situation.
With all this in mind, families can create the ideal watering environment for their houseplants or garden plants and give them the best chance of survival.
