Caring for succulents (a diverse group of plants often from families like Crassulaceae, Cactaceae, and Aizoaceae) in winter means making a few key adjustments to their usual care routine. The most crucial steps are significantly reducing watering, providing them with the brightest possible light, and protecting them from cold temperatures and frost.
How much light do succulents need in winter?
Even in winter, succulents crave bright light. During the shorter days and lower light intensity of colder months, it's essential to give your succulents the absolute brightest spot you have available, ideally a south-facing window in the Northern Hemisphere. Aim for at least 4-6 hours of direct sunlight, supplemented with strong indirect light for the rest of the day.
What if my succulent isn't getting enough light?
If your succulent isn't getting enough light, it will likely start to 'etiolate,' meaning it stretches and becomes leggy as it desperately reaches for a light source. The leaves might also spread out and lose their compact form, and any vibrant stress colors may fade. If you notice these signs, it's a clear signal to move your plant to a brighter location. You might also consider using a grow light, placed 15-30 cm (6-12 inches) above your plants, for 10-12 hours a day to compensate for insufficient natural light. Planta always recommends monitoring your plant's growth closely to catch early signs of light deficiency.
How often should I water my succulents in winter?
In winter, most succulents enter a period of dormancy, meaning their growth slows significantly. This dramatically reduces their water needs, so you should water them much less frequently than you do in warmer months. Wait until the soil is completely dry, and then wait a few more weeks before watering again; for many, this might mean watering only once every 3-4 weeks, or even less frequently.
What's the best way to water a dormant succulent?
When it's time to water, give your succulent a thorough soak rather than small sips. Water deeply until it drains out of the bottom of the pot, and then immediately empty any excess water from the saucer. This ensures the roots are adequately hydrated, but prevents them from sitting in soggy soil, which is a common cause of rot, especially during dormancy. Always use well-draining soil and pots with drainage holes to avoid waterlogged conditions.
What's the ideal winter temperature for succulents?
Most succulents prefer cooler temperatures in winter, ideally between 7-13 °C (45-55 °F), though many common houseplants will tolerate typical indoor temperatures around 18-24 °C (65-75 °F). The key is to protect them from freezing temperatures and cold drafts, which can quickly damage or kill them. If temperatures are consistently below 5 °C (40 °F), you should bring any outdoor succulents indoors.
How do I protect outdoor succulents from frost?
If you live in an area with freezing winters, outdoor succulents need extra protection. The safest option is to bring them indoors to a bright, unheated room or garage where temperatures remain above freezing but are still cool. For succulents that cannot be moved, cover them with frost cloth or blankets when freezing temperatures are expected. Make sure the cover doesn't touch the foliage directly by propping it up, creating a tent-like structure to trap warmer air.
Should I fertilize succulents in winter?
No, you should avoid fertilizing your succulents during their winter dormancy. Just like their water needs, their nutrient requirements are minimal when they're not actively growing. Fertilizing during this period can stress the plant and potentially cause root burn. Resume fertilizing in spring when you see new growth emerging.
Remember, less is often more when it comes to winter succulent care. They are adapted to harsh, dry conditions, and replicating those conditions (reduced water, cool temperatures) helps them thrive.
Here are some quick tips for winter succulent success:
Move them closer to windows: Maximize natural light by placing them directly in front of your brightest windows.
Check soil moisture diligently: Only water when the soil is bone dry and has remained dry for a period of time.
Protect from cold drafts: Keep them away from drafty windows or exterior doors.
Avoid sudden temperature changes: While they appreciate cool temps, extreme fluctuations can be harmful.
Hold off on repotting: Wait until spring or summer when they are actively growing.
Inspect for pests: Reduced plant vigor in winter can sometimes make them more susceptible to pests; check regularly.
Winter care for succulents might seem like a balancing act, but with careful attention to light, water, and temperature, your beloved plants will emerge happy and healthy when spring arrives. By mimicking their natural dormant period, you're setting them up for robust growth in the coming seasons.
