- Provide several hours of sunlight if indoors
- Use cactus fertilizer monthly during growing season
- Repot every 2-3 years in spring into well-draining soil

Avoid overwatering, which can lead to root rot. Let the soil dry out between waterings.
Using Spiky Succulents in Landscape Design
Spiky succulents can be incorporated into landscapes in creative ways:
Borders and Beds
Use spiky varieties as borders along paths, driveways, fences and gardens. The vertical shapes contrast softer plants. Or plant in sweeping beds for texture.
Rock Gardens
Combine spiky succulents with gravel, boulders and stones to mimic natural desert environments in a rock garden setting.
Container Gardens
Plant in containers alone or with trailing succulents. Position on entryways, patios, or anywhere a bold focal point is desired.
Small Accents
Tuck smaller spiky succulents into gaps in retaining walls, steps, or rock walls. They can also accent other plantings in pleasing ways.
Dividing Spaces
Use groupings of tall, upright spiky succulents to divide large landscapes into different sections or "garden rooms" for intrigue.
Add Height
Incorporate taller spiky varieties like large yucca and agave to add height variation and stimulate the eye upward.
Get creative with slopes, groupings, patterns and sections to highlight their unique textures.
Choosing the Right Spiky Succulents
Consider the following when selecting spiky succulent varieties:
Types of Spikes
Choose succulents with spikes along the edges like cacti and sansevieria, or dramatic points at the tips such as yucca and agave.
Mature Size
Look for small, medium or large varieties depending on the space you are filling.
Growth Habit
Select rosette-forming, upright or mounding types depending on the look you want.
Color and Texture
Opt for green, silvery-blue, variegated or other colors. Some have smooth leaves while others are hairy or toothy.
Hardiness
Choose succulents hardy to your USDA zone if planting outdoors.
Combine different shapes, sizes and colors of spiky succulents for the best impact.
Creating Stunning Displays with Spiky Succulents
To create eye-catching succulent arrangements:
Contrast Shapes and Textures
Combine spiky varieties with softer, rounded types for visual interest. Vary heights, shapes and colors.
Repeat for Emphasis
Plant groupings of the same variety together for cohesion and impact. Repeat at intervals.
Use as Focal Points
Choose specimens like large agave and aloe to become dominant features that anchor the design.
Edge with Care
Line walkways, borders and beds with spiky succulents, leaving enough space to avoid being poked.
Mix Planting Types
Incorporate spiky succulents with grasses, flowering perennials and shrubs for diverse textures.
With smart plant choices and combinations, you can create stunning succulent displays.
Common Problems With Spiky Succulents
Watch for these potential issues:
Overwatering
Excess moisture leads to root rot. Allow soil to dry out between waterings.
Etiolation
Insufficient sun causes succulents to stretch and lose compact shapes. Provide ample light.
Frost Damage
Cold causes brown spots and damage. Protect or bring indoors if temps drop.
Pests
Mealybugs and scale insects can attach. Isolate and treat with insecticidal soap sprays.
Mineral Buildup
Hard water leaves white crusty deposits on leaves. Wipe gently and water with distilled or rain water.
Caring properly for spiky succulents prevents most issues and keeps them looking their best.
