Succulent Plants Care Outdoors: A Comprehensive Guide

Succulents are perfect for outdoor spaces because they can thrive in a variety of conditions, including full sun to partial shade.

Choose a spot with good air circulation to prevent fungal diseases, which can be a problem for succulents in humid environments.

Before planting, make sure the soil drains well to prevent waterlogged soil, which can be detrimental to succulents.

Succulents can tolerate some neglect, but they still need regular watering, especially during hot summer months when they can lose a lot of water.

When choosing a spot for your succulents outdoors, keep in mind that they need protection from extreme temperatures. Many succulents can handle full, hot sun, but above 85F they need dappled shade to look their best.

Light needs vary across succulent varieties, but morning sun and partial afternoon shade is ideal for most. Desert types like cacti and Agave can handle full sun, but be cautious not to give them too much direct sun, as it can lead to Succulent Sunburn.

Suggestion: Do Succulent Plants Need Water

To ensure good drainage, use pots with drainage holes, especially for container plantings. Succulents need rapid drainage and prefer a lean, gritty soil like a cactus/succulent mix or sandy loam.

Water your succulents deeply but infrequently, allowing the soil to fully dry between soakings. Frequency will vary by location, but start with about 2-3 times a week to establish young plants, and 1-2 times a week for mature plants in the growing season.

Here's a watering schedule to keep in mind:

Transplanting your succulents can be a bit tricky, but it's essential to remove them from their pot, gently loosen the roots, and plant them in a small hole. Firmly compress the soil around the roots, and wait about 2-4 days to water to allow any broken roots to callus and prevent rot.

When choosing the right succulent for your outdoor space, consider the specific variety you're selecting. Some succulents, like Aeonium, Aloe, and Haworthia, are winter growers and may require more water during this time.

Most succulents, however, prefer little to no water in winter, so it's essential to reduce your watering frequency. This means only watering if the soil is completely dry.

To ensure your succulent gets the right amount of sunlight, place it in its preferred location. This will help it thrive and prevent any potential issues.

Direct sunlight can be harsh on succulents, causing leaves to turn brown or spotted if exposed for too long. This is because succulents require a good amount of sunlight, but extreme sun can be detrimental.

A perfect spot outdoors for succulents is an area that receives 6-8 hours of sunlight and some shade during the intense heat of a summer day. This balance is key to preventing damage from direct sunlight.

If your succulents aren't getting enough sunlight, you may notice them stretching out with a lot of space between their leaves. This is a sign that they're craving more light.

Watering your succulents is a delicate balance, especially during the winter months. Most succulents prefer little to no water in winter, so it's essential to reduce your watering frequency.

In fact, it takes longer for the soil to dry during winter, so you should only water if the soil is completely dry. This will help prevent root rot and other issues that can arise from overwatering.

If you have succulents that thrive in winter, such as Aeonium, Aloe, or Haworthia, you'll need to water them more frequently. However, even these plants will benefit from a reduction in watering frequency.

Here are some key tips to keep in mind:

Succulents don't like to have their roots sitting in wet soil, so it's essential to improve drainage by adding sand or pumice to your soil mix.

Adding sand or pumice to your soil mix is crucial for succulents. Regular sand is okay, but volcanic sands like pumice and scoria are preferred because they keep the soil from being too heavy.

A light, gritty mix like cactus & succulent soil is perfect for succulents. Using a mix like Bonsai Jack's Gritty Mix will ensure good drainage and permanence.

It's best to plant your outdoor succulents in pots that can be moved inside once the temperature drops.

Unless you live in the warmest parts of the country, potting succulents is a good idea. This allows you to control how much water your plants receive, which is especially important for succulents that have delicate roots that can rot when overly saturated.

There's only one way to truly kill a succulent, and that's too much water. This is a common mistake that can happen even in areas with ideal conditions for succulents.

Even in sunny Southern California, where conditions are ideal for succulents, planters can be helpful to prevent scorched plants in the ground.

Succulents prefer soil that drains well, so it's essential to add sand or pumice to your mix to prevent waterlogged roots.

Using a light, gritty mix specifically designed for cacti and succulents is a great way to ensure good drainage. Bonsai Jack's Gritty Mix is a good example of this type of soil.

Adding rocks to the bottom of a pot will not improve drainage, so it's best to use pots with built-in drainage holes. This is a crucial feature for succulents that don't like wet feet.

Protecting your succulents from extreme temperatures is crucial for their survival. Only a few varieties can withstand below-freezing conditions.

Most succulents prefer sun and heat, but some desert environments can be too extreme. Sedums and sempervivums can tolerate below-zero cold, while agaves, some aloes, and most cacti can handle high desert heat conditions.

For mild climates, reliable succulents that can tolerate outdoor conditions year-round include hens and chicks Echeveria 'Sahara', Agave 'Moonshine', Crassula 'Ripple Jade', and Crassula 'Hobbit Jade'.

Succulents need at least two to three hours of sun or filtered sun a day. Some varieties even prefer shade or filtered light.

When growing succulents indoors, place them by a window or in a garden room for at least two or three hours of full sun a day. If not, you can use grow lights to give them the light they need.

A fresh viewpoint: How Much Sunlight Do Succulent Plants Need

Don't be afraid to prune your succulents, especially when they become unruly and several plants are grouped together.

Pruning will help keep one variety from overpowering another. Tipping, clipping, branch removal, and dividing are all acceptable methods.

After pruning, allow the cuttings to dry and heal over at the wound for several days to prevent them from absorbing too much water.

Regularly removing dry or dead leaves at the base and perimeter of the plant will improve its appearance and encourage new growth.

Protecting your succulents from water damage is crucial, especially during winter.

Hardy succulents need less frequent watering in winter, so be careful not to overwater.

If you get cold, wet winters without snow, consider moving your succulents under a roof or using a clear rain cover at least 18.0" above them to keep them dry.

When growing succulents outdoors, it's essential to consider their sensitivity to extreme temperatures.

Succulents can tolerate temperatures as low as 40°F (4°C) and as high as 90°F (32°C), but prolonged exposure to temperatures above 100°F (38°C) can cause damage.

Some succulents, like Echeveria and Crassula, can be sensitive to frost, so if you live in an area with freezing winters, you may need to bring them indoors during the colder months.

Many succulents can live outdoors all year, even in snowy climates. Some people might be surprised to learn this, but it's true.

Hardy succulents can tolerate frost and stay outdoors through below-freezing temperatures. They're ideal for year-round, outdoor growing.

Soft succulent varieties, on the other hand, are not frost-tolerant and must come indoors before nighttime temperatures drop below freezing.

Plant zoning can help determine which succulents can survive outdoors in your climate. Find your USDA Grow Zone based on minimum winter temperature.

Here's a brief guide to help you determine which succulents can stay outside in winter:

Some plants come with name tags that list the minimum temperature they can tolerate. This can be a helpful reference point when deciding whether to bring your succulents indoors or leave them outside.

If you live in an area with harsh winters, you'll want to choose frost hardy outdoor plants that can withstand the cold temperatures.

Some plants that can tolerate temperatures as low as -40°C are Russian sage and boxwood, which are great options for hedges and topiaries.

Keep in mind that even frost hardy plants may still require protection from extreme cold snaps.

Russian sage can grow up to 2 meters tall and 1 meter wide, making it a great choice for adding some height to your garden.

Boxwood is a low-maintenance option that can be pruned to maintain a desired shape.

In areas with frequent frost, it's essential to choose plants that can handle the moisture and cold, such as conifers like spruce and fir.

These conifers can grow up to 10 meters tall and are perfect for creating a natural screen or windbreak.

Frost hardy plants like lavender and rosemary are also great options for adding some color and fragrance to your garden.
