Farming with Native Beneficial Insects
The Xerces Society Guide to Ecological Pest Control Solutions
by Eric Lee-Mader, Jennifer Hopwood, Lora Morandin, Mace Vaughan and Scott Hoffman Black
Empirical research is pointing to the overwhelming pest control benefits provided by native insects. Many of these beneficial insects rely exclusively on native plants and the insect species which co-exist. Farming with Native Beneficial Insects examines the ecology of these insects while including methods for multiplying their population through habitat design and management. This guide also outlines common species of predatory insects, parasitoids and non-insect predators such as spiders, in addition to the native plant species most suitable for beneficial insects.
Lady beetles, syrphid flies, lacewings, and other beneficial insects prey upon crop pests, reducing or eliminating the need for pesticides. This comprehensive guide describes how to recognize these insects and their habitat, and how to evaluate, design, and improve habitat for them. Close-up photography and in-depth profiles familiarize you with more than 20 beneficial insects and their kin. Step-by-step illustrated instructions detail specific solutions including native plant field borders, mass insectary plantings, hedgerows, cover crops, buffer strips, beetle banks, and brush piles.

Seed
Growing your own plants from seed is the most economical way to add natives to your home. Before you get started, one of the most important things to know about the seeds of wild plants is that many have built-in dormancy mechanisms that prevent the seed from germinating. In nature, this prevents a population of plants from germinating all at once, before killing frosts, or in times of drought. To propagate native plants, a gardener must break this dormancy before seed will grow.
Each species is different, so be sure to check the GERMINATION CODE listed on the website, in the catalog, or on your seed packet. Then, follow the GERMINATION INSTRUCTIONS prior to planting. Some species don't need any pre-treatment to germinate, but some species have dormancy mechanisms that must be broken before the seed will germinate. Some dormancy can be broken in a few minutes, but some species take months or even years.
Seed dormancy can be broken artificially by prolonged refrigeration of damp seed in the process of cold/moist STRATIFICATION. A less complicated approach is to let nature handle the stratifying through a dormant seeding, sowing seeds on the surface of a weed-free site in late fall or winter. Tucked safely beneath the snow, seeds will be conditioned by weathering to make germination possible in subsequent growing seasons.

Dormant Bare Root Plants
We dig plants when they are dormant from our outdoor beds and ship them April-May and October. Some species go dormant in the summer and we can ship them July/August. We are among the few still employing this production method, which is labor intensive but plant-friendly. They arrive to you dormant, with little to no top-growth (bare-root), packed in peat moss. They should be planted as soon as possible. Unlike greenhouse-grown plants, bare-root plants can be planted during cold weather or anytime the soil is not frozen. A root photo is included with each species to illustrate the optimal depth and orientation. Planting instructions/care are also included with each order.

Potted Plants
3-packs and trays of 32, 38, or 50 plants leave our Midwest greenhouses based on species readiness (being well-rooted for transit) and order date; Spring shipping is typically early May through June, and Fall shipping is mid-August through September. Potted 3-packs and trays of 38 plugs are started from seed in the winter so are typically 3-4 months old when they ship. Trays of 32/50 plugs are usually overwintered so are 1 year old. Plant tray cells are approximately 2” wide x 5” deep in the trays of 38 and 50, and 2.5" wide x 3.5" deep in the 3-packs and trays of 32; ideal for deep-rooted natives. Full-color tags and planting & care instructions are included with each order.
