• Nutrients: Benefits from the slow release of nutrients from decomposing organic matter found in forest soils.

Successfully replicating these conditions in a garden setting is the first step towards a successful Jack-in-the-pulpit garden. Companion planting can further support these needs by contributing to soil health, moisture retention, and pest deterrence.

The Principles of Companion Planting for Forest Floor Gardens

Companion planting is rooted in observation of natural ecosystems. In the wild, plants don’t grow in monocultures; they exist in diverse communities, each species playing a role and interacting with its neighbors. The goal of companion planting is to harness these natural synergies to benefit your garden.

For forest floor gardens, these principles translate to:

• Nutrient Cycling: Some plants can fix nitrogen, while others decompose easily, adding organic matter back into the soil.
• Pest and Disease Management: Certain plants can repel pests or attract beneficial insects that prey on garden nuisomes.
• Moisture Regulation: Groundcovers can help retain soil moisture and prevent rapid drying.
• Support and Structure: Taller plants can provide shade for shade-loving undergrowth, while sprawling plants can create a living mulch.
• Biodiversity: A variety of plants attracts a wider array of pollinators and beneficial organisms, creating a more balanced ecosystem.

When selecting companions for Jack-in-the-pulpit, we look for plants that share similar growing conditions – shade-tolerant, moisture-loving, and appreciative of rich, organic soil.
