As the Melbourne Winter starts to approach we need to start to thinking about keeping our plants happy and healthy.Here are horticulturalist David Clark’s top 10 tips to keep them smiling ( Images and words courtesy of Gardenista)!

But whether you’re nursing something finicky like an African violet or a hardy Mother in Law’s tongue, your houseplants are going to have a harder time in winter. Here’s how to make them happier:
- Cut back on water.
- Give them sunshine.
- Add moisture to indoor air.
- Stop fertilizing until spring.
- Dust your plants.
- And give them a bath once in a while.
- Crank up the heat, then turn it way down (every day).
- Avoid re-potting if possible.
- Conduct a weekly bug inspection.
- Give sick plants a natural tonic.
- Sing them lullabies (could it hurt? plants love music).

Water: “Most plants only need water once a week in winter,” says Clark. “They will kind of go dormant, especially if they’re plants that grow outdoors in summer and they’ve come from that bright light into a home with lower lighting and lower temperatures.”

Sunshine: Put them in the sunniest spot in the house; most them to follow the sun if necessary. “Most plants will not thrive in a north-facing window because they need more sun,” says Clark. The best? A window facing east; you will get sun from 7 am to 11 am and “it’s not harsh, like what you’ll get in a western facing window,” he says.

Humidity: Most plants thrive with levels of from 50 to 60 percent humidity; in a house the humidity level can go below 35 percent. “In a situation like that, make them a little miniature greenhouse by tenting them under a big plastic bag,” says Clark. “Or take a shallow tray, fill it with 2 inches of water and gravel, and set your potted plant in it.” As the water evaporates, it will create humidity around the plant.

Keep plants clean: “When they get dusty, that causes plants not to breathe. It plugs their leaves, which have little pores called stomata,” says Clark. “If you cover a leaf surface with dirt, it won’t get the full effect of sunlight and photosynthesis will be slowed.”
Solution? For smaller plants, give them a bath in a sink with a sprayer. Larger plants can go into the shower. Wipe leaves with a damp sponge. Then off their leaves so they don’t drip all over the floor.
