You can use a hygrometer to measure humidity levels.
Plant leaves are covered in stomata, tiny pores through which the plant breathes during transpiration. Water changes to vapour and is released into the atmosphere, while the plant takes in carbon dioxide for photosynthesis. During this process the plant loses water through its pores and needs to quickly replace lost H20 before the leaves crisp up. Sometimes it can’t always replace this lost moisture fast enough through the roots.
Transpiration is the process by which moisture is carried through plants from roots to small pores on the underside of leaves.
Watch out for: Symptoms of dry air include curled leaves and dry leaf tips.
One of the easiest ways to raise the humidity around your plant is to mist its leaves with a spray bottle filled with water. Some plant gurus say this does not help your plant (and is more beneficial as therapy for humans). But The Atrium has tried and tested this method and found it to be successful.
For it to work, you must mist the leaves enough so that the water actually drips off them and they are completely wet. Misting like you’re spritzing yourself with L’Eau Issey Miyake Pure Nectar won’t help. You gotta spray, like hair spray when you want your hairdo to stay put during a whole night of dancing kinda spray!
By wetting the leaves well once a day, it gives the stomata a chance to absorb moisture.
Besides keeping your plants healthy, humidifiers have loads of benefits for us humans including: reducing asthma, keeping skin and hair vibrant and moist, easing sinus congestion, purifying the air of pollutants and reducing cases of flu.
By placing plants on a tray of water with pebbles, gravel or stones you raise the humidity around the plant’s immediate environment, creating a more humid micro-climate. Fill the tray with water, without letting the water cover the tops of the pebbles. Place your plant on the pebbles.
The reason the water must not cover the tops of the stones is because you don't want your plant sitting in water, which can cause root rot. It's better for it to be slightly elevated above the water. The H20, however, will create humidity. The down size of this method is that it doesn’t always look super stylish.
If you’re placing plants in a row you can use a trendy tray, or cluster plants together behind a couch where it will obscure the view of the pebble trays. Or you can make the pebbles part of the display using stunning decorative stones.
Our Japanese pumice stones are a great way to increase humidity levels. Place them at the bottom of your decorative pot, underneath the grow pot. The pumice is highly absorbent, which not only prevents water from pooling in the pot, the absorbed water is retained by the pumice, increasing humidity around the plant. This method also looks much neater, as you can’t see the stones hidden at the bottom of the decorative pot.
By placing peat moss dunked in water, in between the little gap between the grow pot and the decorative planter, you can increase humidity even further. It’s also an ‘invisible’ method.
Plants together raise the humidity levels. When a plant releases moisture through breathing, its friend absorbs it – a bit like kissing catches. What’s more, plant groupings look great! And this is a practical way to ensure plants are ok during holidays or time away.
Self-watering planters help ensure that when plants transpire there’s a readily available source of water for the roots to suck up and replace moisture in the leaves.
