❓ Frequently Asked Questions — Comparing These Plants

Ocotillo

What are the light requirements for Ocotillo?

Ocotillo thrives in bright, direct sunlight. It needs at least 6 hours of direct sunlight per day to maintain its vibrant color and promote healthy growth. An east- or south-facing window is ideal. Insufficient light can cause etiolation, resulting in weak, elongated stems and pale foliage.

How do I care for Ocotillo?

Ocotillo requires well-draining soil, such as a cactus mix amended with perlite or gravel. Water thoroughly only when the soil is completely dry, typically every 2-4 weeks during the growing season (spring/summer) and even less frequently during dormancy (fall/winter). Provide at least 6 hours of direct sunlight daily. Ocotillo is highly drought-tolerant and prefers dry conditions.

How do I propagate Ocotillo?

Ocotillo can be propagated through stem cuttings. Allow the cut end to callous over for several days before planting in well-draining soil. Keep the soil lightly moist until roots develop. Propagation from leaf cuttings or offsets is not typically done with Ocotillo, as it primarily propagates from stems.

Pulmonaria

What are the light requirements for Pulmonaria?

Pulmonaria thrives in partial to full shade. In regions with hot summers, full shade is essential to prevent leaf scorch. Morning sun is tolerated, but avoid direct afternoon sun. The ideal location receives dappled sunlight throughout the day. Insufficient light can result in fewer blooms and less vibrant foliage.

How do I care for Pulmonaria?

Pulmonaria prefers partial to full shade, especially in warmer climates. Direct sunlight can scorch the leaves. The ideal location is one that receives morning sun and afternoon shade. Plant in well-draining, humus-rich soil that retains moisture. Water regularly, especially during dry periods, keeping the soil consistently moist but not soggy.

How do I propagate Pulmonaria?

Pulmonaria is most easily propagated by division in early spring or fall. Carefully dig up the plant and separate the root ball into smaller clumps, ensuring each clump has healthy roots and foliage. Replant the divisions in well-draining, humus-rich soil. Keep the soil consistently moist until the plants are established.
