Even though plants generally need less water and sunlight during winter, lack of care for several days can cause them to wilt or slow their growth. If you’re heading out for a winter holiday, a little preparation before you leave can help keep your houseplants healthy.
Watering arrangements
In winter, soil dries slowly but leaving plants without water for too long can still harm the roots. Therefore, before leaving:
Water plants adequately based on their needs.

Mulch the topsoil with dry leaves, straw or coconut husk to retain moisture for longer.
Use a self-watering bottle — fill a bottle with water, make a small hole in the cap, and insert it upside down into the soil so the water releases slowly.
Try the wick system — place a cotton string from a water-filled container into the pot’s soil. The soil will absorb water as needed.
(All of these are widely used, safe and effective home methods.)
Light and temperature
Place plants where they receive soft natural light, such as near a window or balcony.
To protect them from chilly winter nights, close windows or curtains so cold drafts do not hit the plants directly.
Keep indoor plants away from drafts and open windows to prevent temperature shock.
Fertilizing
Trim dry leaves and dead stems before you leave, this reduces pest and fungal problems.
Winter requires less fertilizer, but you may use a small amount of slow-release fertilizer, which will continue to provide nutrients for several weeks.

Pest control
Check the underside of leaves for pests such as mealybugs, aphids or fungal spots.
Clean with a damp cloth, or apply neem oil spray if required.
Clean plants stay healthier even when unattended.
