Plantsmith Fortifying Houseplant Tonic

Unlike outdoor plants, houseplants are completely reliant on their hosts to keep them well fed. Although they arrive in compost that contains low levels of fertiliser, these nutrients are quickly used up, typically within 6-8 weeks. Using a good plant food will ensure your houseplants are getting the vital minerals and vitamins they need to flourish.

It’s best to feed houseplants regularly during their growing season, which runs from March to September. During this time, use Fortifying Tonic every other time you water your indoor plants. Mixing it couldn’t be easier - simply shake the bottle well and mix 5 ml (approximately 4 pumps) into a litre of tepid water and apply to the compost at the base of the plant. For younger plants mix the same amount into 2 litres of water so that it's slightly weaker.

Ensure your plants do not sit in water as this will rot the roots and kill the plants. Come back and check 15 minutes after watering and pour away any water that remains in the saucer or planter.

Plantsmith Perfecting Houseplant Care Mist

Many of our favourite houseplants originally come from tropical climates where they flourish in humid conditions. Our warm, dry homes mean they lose moisture quickly. This can cause leaves to wilt and turn crisp or result in flower buds dropping before they open. Regularly use of a houseplant mist spray, especially during colder months when central heating is on, can help to simulate the jungly atmosphere our plants crave.

To use, shake the bottle well and then mist the leaves until it looks like a fine dew has settled on them. Then gently spritz the top of the compost to moisten it. Take care to avoid directly spraying flowers as excessive moisture can spoil them. Other than that, use the spray as often as you wish and enjoy the subtle lavender aroma.
