Use budget, easy-to-lay blocks to build a decorative display for succulents that costs just $250. Concrete blocks are inexpensive, stackable and durable, with two cavities that are ideal for plants. This mortared wall is made of eight courses using 26 blocks and four half-blocks, with 16 used as planters. Dry-stack the blocks to get the best configuration for the space, make a mortar mix and lay them in position.
Include full and half blocks in the wall with seven set perpendicular to the rows, half-lapping in position. The planter wall is decorative and was built on the footing of a raft slab in a spot protected from the elements. For extra safety, each block course is securely tied to the existing brick wall using Grade 316 stainless steel ties.
Choose the plants
Succulents are a good choice for a planter wall as they are drought tolerant, hardy and low maintenance. Many succulents, such as certain varieties of aloe, echeveria and kalanchoe, grow well in both full sun or shaded positions. Choose this size so the rootballs ft in the cavities of the blocks and allow enough room for growth. Go for a combination of upright and cascading succulent varieties, mixing up the foliage shape, texture and colour for an eye-catching and structural display.
Use a good quality, free-draining potting mix or buy a specially formulated cacti and succulent mix, watering the plants in well. Once established, water only once a week in summer and every two to three weeks in winter.
Tip Ensure the drainage is efficient as succulents rot if left standing in water.
