A planter is a container or a structured bed designed to hold soil and plants. It allows gardeners to grow flowers, herbs, vegetables, or small shrubs above ground level. Planters are particularly useful for people with limited space, poor soil conditions, or mobility challenges, as they offer controlled environments for plant growth. 

Characteristics of a Planter for Raised Gardens:

1. Raised Structure: Planters elevate the soil above ground, making them easier to work with and improving drainage.
2. Materials: Planters can be made from wood, metal, plastic, concrete, or ceramic. Wood planters (such as cedar or redwood) are commonly used in raised gardens due to their durability and natural aesthetic.
3. Size and Shape: Planters come in various shapes (rectangular, square, round) and sizes, depending on the space and the plants being grown. The depth of the planter is important, as deeper containers allow for root vegetables and larger plants.
4. Soil Containment: Planters are designed to hold soil within a defined space. This allows gardeners to add their choice of soil mix for specific plants, which is especially useful if the native ground soil is of poor quality.
5. Drainage: Most planters include drainage holes to prevent water from pooling at the bottom, which could lead to root rot or other issues. Some may have a raised or false bottom to improve drainage further.
6. Portability: Some smaller planters are movable, allowing gardeners to reposition them to different locations, either for better sunlight or to protect plants from weather conditions.

Benefits of Planters for Raised Gardens:

• Soil Control: Allows control over the type and quality of soil used, which can improve plant growth, especially in areas with poor soil.
• Mobility: Smaller planters can be moved easily if needed.
• Ease of Access: Raised planters make it easier to tend to plants without needing to kneel or bend over as much, making them ideal for people with limited mobility.
• Aesthetics: Planters add structure and design to a garden space, making them not only functional but also decorative.

Overall, planters in raised gardens offer flexibility, improved growing conditions, and a more accessible way to enjoy gardening.
