Shipping fee is included (within the contiguous US). Phydura™ is an OMRI listed, non-selective herbicide made from natural, biodegradable ingredients (clove oil, lactic acid, potassium oleate, vinegar, and water) for herbaceous broadleaf and grass weeds including: Garlic Mustard, Burdock, Dandelion, Clover, Crabgrass, Queen Anne's Lace, Pigweed, Velvet Leaf, Ragweed, Quack Grass, Leafy Spurge and more!
Kills annual weeds within hours; perennials may need 2 or more applications to kill the roots. Phydura™ is safe around (but not on) trees, shrubs and water. Phydura™ is a non-selective contact weed killer; it will control anything it comes in contact with, but complete spray coverage is needed (enough to wet the plant, but not to the point of run-off). Phydura™ works best on actively growing plants in full sun and air temps above 70 degrees; the warmer, the better.
How much Phydura™ do I need?
- For young or small weeds, mix 1 part Phydura™ to 3 parts water (3:1 ratio). Spray entire plant.
- For spray application of the diluted product, you would need 2 gallons per 1000 sq ft. (90 gallons/acre) So then, 0.5 gallons (64oz) of undiluted Phydura™ needed per 1000 sq ft.
- 1 quart of product will make 4 quarts of spray. Likewise, 2.5 gallons of product will make 10 gallons of spray.
- For larger or older weeds, mix 1 part Phydura™ to 2 parts water (2:1). Spray entire plant.
- For lawn grass, mix 1 part Phydura™ with 2 parts water (2:1 ratio).
- 1 quart of product will make 3 quarts of spray. Likewise, 2.5 gallons of product will make 7.5 gallons of spray.
- NOTE: we do not recommend using Phydura to kill lawn grass to prepare for a native seeding. Multiple sprayings make it impractical.
Although it is safe to enter a Phydura™ treated area when the spray has dried, we suggest waiting 24 hours before sowing seed or transplanting.
Keep the concentrate out of reach of children and pets as it can cause eye irritation. As with any spray treatment, wear safety glasses and gloves when applying. Download the SDS (Safety Data Sheet).
Ingredients: Active = Citric Acid (32%), Clove Oil (8%), Malic Acid (10%) Other = Lactose, Oleic Acid and Water (50%).
9 Questions asked on Phydura All Natural Herbicide
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.

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.
