Why Move Your Succulents Outdoors?
Bringing your succulents outside can be incredibly rewarding. They often experience more robust growth, develop brighter colors, and can even bloom more profusely when given the right outdoor conditions. Think about it: they get more natural sunlight, better air circulation, and can become a stunning part of your landscape design. Plus, for many varieties, the cooler temperatures outdoors can encourage spectacular stress colors – beautiful reds, purples, and oranges that you rarely see indoors.
It’s a fantastic way to expand your gardening horizons and enjoy these unique plants in a whole new way. Don’t worry if you’re new to this; we’ll cover everything you need to know to make the transition smooth and successful.
Choosing the Right Spot for Your Outdoor Succulents
Location, location, location! Just like us, succulents have their preferences when it comes to where they live. The best spot for your outdoor succulents will depend on your climate and the specific types of succulents you’re growing. Most succulents love sunshine, but even they can get a sunburn in extreme heat.
Key Considerations for Location:
- Sunlight: Aim for at least 6 hours of bright, indirect sunlight per day. Morning sun is usually ideal, especially in hotter climates.
- Protection from Extreme Heat: In regions with scorching afternoon sun (think deserts or very hot summers), provide some shade during the hottest part of the day. A spot that gets morning sun and afternoon shade is often perfect.
- Air Circulation: Good airflow helps prevent fungal diseases and keeps pests at bay. Avoid damp, stagnant corners.
- Drainage: This is CRUCIAL. Waterlogged roots are the quickest way to kill a succulent. Ensure the area drains well naturally or that your containers can easily shed excess water.
- Protection from Frost: If you live where temperatures drop below freezing, you’ll need to move your succulents indoors or provide protection during winter.
Consider grouping your succulents together. This can create a microclimate that offers some protection to individual plants, and it also makes it easier to manage their watering and care. Elevated planters, hanging baskets, or even raised garden beds can also improve drainage and airflow.
The Golden Rule: Drainage, Drainage, Drainage!
If there’s one thing you absolutely must get right for outdoor succulents, it’s drainage. Succulents are desert plants adapted to arid conditions. Their fleshy leaves and stems store water, meaning they can go a long time without being watered. However, they have very little tolerance for sitting in soggy soil. Constantly wet roots will rot, leading to a quick demise.
What You Need for Excellent Drainage:
- The Right Soil Mix: Forget regular potting soil! Succulents need a gritty, fast-draining mix. You can buy cactus and succulent soil or make your own. A good DIY mix is usually 50% potting soil and 50% inorganic material like perlite, pumice, or coarse sand. This mimics their natural rocky, well-draining habitats. More information on soil can be found at the Royal Horticultural Society for general potting advice, which applies to drainage principles.
- Porous Pots: If you’re planting in containers, opt for terracotta or unglazed ceramic pots. These materials allow water to evaporate from the sides, helping the soil dry out faster than plastic or glazed pots. Always ensure pots have drainage holes at the bottom.
- Elevated Planting: Raised beds or containers sitting on pot feet improve airflow and allow water to escape freely.
When in doubt, err on the side of too gritty rather than too rich. Your succulents’ roots will thank you!
Sunlight Requirements for Outdoor Succulents
Sunlight is like food for succulents. They need plenty of it to thrive, grow compactly, and develop those stunning colors. Outdoors, they generally get far more light than they would indoors, which is a good thing!
Understanding Sunlight Needs:
- Full Sun (6+ hours direct sun): Many hardy succulents, like Sempervivums (Hens and Chicks) and many Sedums, love full sun all day. This can lead to the most vibrant colors and dense growth.
- Partial Sun/Bright Indirect Light (4-6 hours direct sun or bright light all day): Most common container succulents, such as Echeverias, Graptopetalums, and many Aloes, do best with morning sun and some protection from intense afternoon rays.
- Shade (less than 4 hours direct sun): Some succulents, particularly those native to shadier spots or with very thin leaves, can tolerate more shade. However, prolonged shade can lead to etiolation (stretching for light) and weaker growth.
Watch for Sunburn: Even succulents that love sun can get scorched, especially if they’re moved suddenly from lower light conditions. Look for brown or white patches on the leaves. If you see this, move them to a spot with a little more shade, particularly during the hottest part of the day. Gradually introduce them to more sun over a week or two to acclimate them.
Signs of Not Enough Light: If your succulents start stretching out, becoming leggy with large gaps between leaves, and losing their vibrant coloring, they’re likely not getting enough light. Move them to a sunnier location.

Watering Your Outdoor Succulents: Less is More!
This is where most beginners get a little nervous, but it’s actually quite simple once you get the hang of it. The key to watering succulents outdoors is to mimic their natural environment: infrequent but thorough watering.
The “Soak and Dry” Method:
- Check the Soil: Never water on a schedule. Instead, feel the soil. Stick your finger about an inch or two into the soil. If it feels dry, it’s time to water. If you feel any moisture, wait longer.
- Water Deeply: When you do water, drench the soil thoroughly until water runs out of the drainage holes. This encourages roots to grow deeper into the pot, making the plant more resilient.
- Allow to Dry Completely: Let the soil dry out completely between waterings. This might mean watering once a week in hot weather, or once a month (or even less!) in cooler or wetter periods. Outdoor succulents often dry out faster than indoor ones due to sun and wind.
Important Notes:
- Rainfall: If your succulents are in a spot where they receive rain, adjust your watering accordingly. You might not need to water them at all during rainy spells.
- Overwatering Signs: Yellowing, mushy leaves that may fall off easily are classic signs of overwatering.
- Underwatering Signs: Wrinkled, deflated-looking leaves can indicate thirst.
Watch the Weather: Pay attention to heatwaves and prolonged dry spells. You may need to water more frequently. Conversely, during cool, damp seasons, reduce watering significantly.
Feeding Your Outdoor Succulents (It’s Minimal!)
Succulents are not heavy feeders. In their native, often nutrient-poor environments, they’ve adapted to survive and thrive on very little. Over-fertilizing can actually harm them, leading to weak, leggy growth and making them more susceptible to pests and diseases. Less is definitely more when it comes to feeding succulents.
When and How to Feed:
- Growing Season Only: The best time to fertilize is during their active growing season (usually spring and summer). Avoid fertilizing in fall and winter when growth slows down significantly.
- Diluted Fertilizer: Use a fertilizer specifically formulated for cacti and succulents, or a balanced liquid fertilizer diluted to ¼ to ½ strength.
- Infrequent Application: Aim to fertilize only once or twice during the entire growing season. Many gardeners find they don’t need to fertilize at all if they’re using a good quality potting mix that contains some nutrients.
- Apply to Moist Soil: Never fertilize dry plants. Water them lightly first, then apply the diluted fertilizer.
For most outdoor succulents, especially those planted in the ground or in good quality potting mix, you can skip fertilizing altogether. They are incredibly forgiving plants!
Protecting Outdoor Succulents from Pests and Diseases
While outdoor succulents are generally quite hardy, they can still encounter pests and diseases. Good care practices are your first line of defense!
Common Pests Include:
- Mealybugs: Small, white, cottony insects that cluster in leaf axils and on stems. They suck sap from the plant.
- Aphids: Tiny, green, black, or brown insects often found on new growth.
- Scale: Small, immobile bumps on stems and leaves that feed on plant sap.
- Slugs and Snails: Can chew holes in leaves, especially during damp periods.
Dealing with Pests:
- Manual Removal: For small infestations, you can flick pests off with your fingers or a soft brush.
- Rubbing Alcohol: Dip a cotton swab in 70% isopropyl rubbing alcohol and dab it directly onto pests like mealybugs or scale. It dissolves their protective coating.
- Insecticidal Soap or Neem Oil: These are organic options that work well. Follow product instructions carefully, and test on a small area of the plant first. You can learn more about beneficial insects and organic pest control at the University of California Agriculture and Natural Resources.
- Encourage Predators: Ladybugs and lacewings are natural predators of aphids and mealybugs.
Common Diseases:
- Root Rot: Caused by overwatering and poor drainage. This is the most common killer of succulents.
- Fungal Spots: Appear as discolored spots on leaves, often due to high humidity and poor air circulation.
Preventing Diseases:
- Proper Watering: The absolute best prevention is to avoid overwatering and ensure excellent drainage.
- Good Airflow: Don’t overcrowd your plants.
- Remove Debris: Keep the area around your succulents clean.
- Remove Affected Parts: If you see signs of fungal spots, carefully remove the affected leaves or stems and dispose of them away from your plants.
Regularly inspecting your plants is key to catching any problems early.
Winterizing Outdoor Succulents: Preparing for Cold Weather
Chilly weather can be a death sentence for many succulents if they aren’t protected. The extent to which you need to winterize depends heavily on your local climate and the hardiness of your specific succulent varieties.
Understanding Hardiness Zones:
Knowing your USDA Plant Hardiness Zone can help you choose succulents that are more likely to survive winter outdoors in your region. You can determine your zone using the USDA Plant Hardiness Zone Map.
Succulent Hardiness:
Some succulents are surprisingly cold-hardy:
- Hardy to Zone 5 or Colder: Many Sempervivum (Hens and Chicks) and some Sedum varieties (like ‘Autumn Joy’ or Sedum spurium) can withstand significant frost and snow.
- Hardy to Zone 8-10: Many Agave, Aloe, and some Echeveria varieties can tolerate light frosts but will be damaged by hard freezes.
- Frost Tender: Most Echeverias, Graptopetalums, Haworthias, and many other popular container succulents are frost-tender and will not survive freezing temperatures.
Winter Protection Strategies:
- Bring Them Indoors: For frost-tender succulents, the easiest and safest method is to bring them inside before the first frost. Treat them like houseplants during the winter, providing bright light and minimal watering (only when the soil is dry).
- Move to a Protected Area: If you have a garage, porch, or greenhouse that stays above freezing, you can move them there. They will likely go dormant and won’t need much light or water.
- Covering: For marginally hardy plants outdoors, you can cover them with frost cloth, blankets, or even an overturned pot on a single cold night. Remove the cover once the temperature rises above freezing to prevent rot.
- Mulching: For hardy succulents planted in the ground, a layer of mulch can help insulate their roots. Avoid piling mulch directly against the crowns of the plants.
- Drainage is Key: Even hardy succulents need good drainage in winter. If they are in containers, ensure they are not sitting in accumulated water.
Remember to stop fertilizing in late summer or early fall to allow plants to harden off before cold weather arrives.
