Succulent gardens are not only beautiful but also relatively low – maintenance, making them a great addition to any outdoor space. Here are the steps and considerations to start your own outdoor succulent garden.
Site Selection
Sunlight Exposure
Ideal Sunlight Conditions
Most succulents thrive in full sun to partial shade. When choosing a site for your succulent garden, look for an area that receives at least 6 hours of direct sunlight per day. South – facing or west – facing locations are usually good choices as they get plenty of sunlight. However, in extremely hot climates, some afternoon shade can be beneficial to prevent the succulents from getting scorched during the hottest part of the day.
Avoiding Shaded Areas
Avoid areas that are constantly shaded, such as under large trees or in the shadow of buildings. Lack of sufficient sunlight can cause succulents to stretch and become leggy as they try to reach for more light. This can make them weak and more susceptible to diseases and pests.
Drainage
Importance of Good Drainage
Succulents cannot tolerate wet feet, so excellent drainage is crucial. The site should be on higher ground or have a natural slope to allow water to drain away quickly. If the area tends to hold water after rainfall, you may need to consider creating raised beds or improving the drainage by adding gravel or sand to the soil.
Testing Drainage
Before starting your garden, test the drainage of the chosen site. Dig a hole about 12 inches deep and fill it with water. If the water takes more than a few hours to drain completely, the drainage is poor, and you’ll need to take measures to improve it.
Soil Preparation
Well – Draining Soil Mix
Soil Composition
Create a well – draining soil mix for your succulent garden. A good starting point is to combine equal parts of potting soil, coarse sand, and perlite or pumice. The potting soil provides some nutrients and a base for the plants to grow in, while the coarse sand and perlite/pumice improve drainage by creating large air pockets in the soil.
Avoiding Heavy Soils
Avoid using garden soil or clay – based soils as they hold too much water and can suffocate the succulent roots. These types of soils can lead to root rot, which is one of the most common problems in succulent gardening. If you have no choice but to use existing soil in your yard, amend it with large amounts of sand and perlite to improve its drainage properties.
Adding Amendments
Nutrient – Rich Amendments
In addition to improving drainage, you can add some nutrient – rich amendments to the soil. Compost can be added in small amounts (about 10 – 20% of the total soil volume) to provide slow – release nutrients. However, be careful not to overdo it with compost as too much organic matter can hold water and disrupt the balance of the well – draining soil.
pH Adjustment
Most succulents prefer slightly acidic to neutral soil with a pH between 6.0 and 7.0. Test the pH of your soil mix and make adjustments if necessary. If the soil is too acidic, you can add lime to raise the pH. If it’s too alkaline, sulfur can be used to lower the pH.
Succulent Selection
Climate – Adapted Species
Understanding Your Climate
When choosing succulents for your outdoor garden, consider your local climate. In areas with mild winters and hot summers, a wide variety of succulents can be grown. For example, Echeveria, Sedum, and Sempervivum are popular choices. In colder climates, look for cold – hardy succulents such as certain types of Sedum and Hens and Chicks (Sempervivum), which can tolerate frost and even snow.
Hardiness Zones
Check the hardiness zones of the succulents you plan to plant. The United States Department of Agriculture (USDA) hardiness zones can give you an idea of which plants are likely to survive the winter in your area. Make sure to select succulents that are suitable for your zone or choose to grow tender succulents as annuals or in containers that can be brought indoors during the cold months.
Color and Texture Varieties
Aesthetic Considerations
To create an appealing succulent garden, choose a variety of succulents with different colors and textures. You can combine succulents with green, blue – green, purple, or variegated leaves. For texture, include some with smooth, waxy leaves like Echeveria, and others with fuzzy or spiky textures such as Kalanchoe tomentosa or Agave.
Growth Habits
Also consider the growth habits of the succulents. Some grow in rosettes, like many Echeverias, while others spread or trail, such as certain types of Sedum. Mixing different growth habits can add depth and interest to your garden design.
Planting
Spacing
Proper Spacing
When planting succulents, give them enough space to grow. The spacing will depend on the size of the mature plants. As a general rule, small succulents like some Sedum species can be planted about 4 – 6 inches apart, while larger ones like Agave may need 1 – 2 feet of space between them. Adequate spacing allows for good air circulation, which helps prevent fungal diseases.
Grouping Similar Succulents
Group similar succulents together for a more cohesive look. For example, you can create a mass planting of one type of Echeveria or a combination of different Echeveria varieties. This also makes it easier to care for the plants as they will have similar water and sunlight requirements.
Planting Depth
Planting at the Right Depth
Plant succulents at the same depth as they were in their original containers. Do not bury the stems or leaves too deeply as this can cause them to rot. Gently loosen the roots of the plants before placing them in the hole and backfill with the prepared soil mix, firming it gently around the roots.
Watering and Maintenance
Watering Schedule
Initial Watering
After planting, water the succulent garden thoroughly to help the plants settle in. However, be careful not to over – water. Let the water soak into the soil and drain away completely.
Establishing a Routine
Once established, succulents in an outdoor garden usually need less frequent watering than other garden plants. Water deeply but infrequently. In general, during the growing season (spring and summer), water when the top 1 – 2 inches of soil are dry. In the fall and winter, reduce watering significantly as the plants enter a dormant state.
Adjusting for Rainfall
Take into account the amount of rainfall in your area. If there has been sufficient rain, you may not need to water at all. You can use a rain gauge to monitor the rainfall and adjust your watering schedule accordingly.
Mulching
Benefits of Mulch
Applying a layer of mulch around the succulents can have several benefits. A thin layer of gravel or small stones can help with drainage, prevent weeds, and add an aesthetic touch to the garden. Organic mulches like shredded bark can also be used, but be careful not to pile them too thickly around the succulents as they can hold moisture.
Mulch Depth
If using gravel or stones, a layer about 1 – 2 inches thick is usually sufficient. For organic mulches, keep the layer to no more than 1 inch to avoid retaining too much water near the plants.
Fertilization
Fertilizer Types
Succulents do not require a lot of fertilization. Use a balanced, slow – release fertilizer formulated for succulents or cacti. You can also use a diluted liquid fertilizer during the growing season, but apply it sparingly. Over – fertilization can cause excessive growth and make the plants more vulnerable to pests and diseases.
Fertilization Frequency
Fertilize your succulent garden once or twice a year, preferably in the spring and early summer when the plants are actively growing. Follow the instructions on the fertilizer package for the correct application rate.
Pest and Disease Control
Common Pests
Outdoor succulent gardens may be susceptible to pests such as aphids, snails, and slugs. Inspect your plants regularly for any signs of pest infestation. Aphids can be removed by spraying the plants with a strong jet of water or using insecticidal soap. For snails and slugs, you can use physical barriers like copper tape around the garden or set out traps.
Diseases
The most common disease in succulents is root rot caused by over – watering. To prevent this, ensure good drainage and proper watering practices. Fungal diseases can also occur, especially in humid conditions. If you notice any signs of disease, such as discolored or mushy leaves, remove the affected parts immediately and improve air circulation around the plants.
Conclusion
By following these steps and guidelines, you can create a beautiful and thriving outdoor succulent garden that will bring you joy for years to come.
