Product Details

Product Details

Listed by the Organic Materials Review Institute (OMRI) for use in organic production, Bi-Carb's active ingredient is a microencapsulated form of good old baking soda. It works by disrupting the potassium ion balance in the fungus that causes powdery mildew, causing the cell walls to collapse. Use it for a natural control of powdery mildew on Roses, vegetables, herbs, Grapes, fruit trees, and ornamentals.

For best results, begin spraying at the first sign of disease. For foliage, mix 2 teaspoons Bi-Carb to 1 gallon of water, and apply with a hand-held sprayer to cover leaves thoroughly. For lawn applications, one 4 oz bottle makes 12 gallons of spray, which covers 6,000 sq ft. Direct contact is essential for control. Apply spray within 24 hours after mixing.




The size of the plants we ship has been selected to reduce the shock of transplanting. For some, this means a large, bareroot crown. Others cannot travel bareroot or transplant best if grown in containers. We ship these perennials and annuals in 1 pint pots, except as noted. We must point out that many perennials will not bloom the first year after planting, but will the following year, amply rewarding your patience. We ship bulbs as dormant, bare bulbs, sometimes with some wood shavings or moss. Shrubs, Roses, vines, and other woody plants may be shipped bareroot or in pots. The size of the pot is noted in the quick facts for each item.


We ship our bulbs and plants at the right time for planting in your area, except as noted, with orders dispatched on a first-come, first-served basis by climate zone. Estimated dates for shipping are indicated in the Shipping Details box for each item. Please refer to the Shipping Details box to determine the earliest shipping time. Unless you specify otherwise, fertilizers, tools, and other non-plant items are shipped with your plants or bulbs. Please supply a street address for delivery. Kindly contact us with two weeks notice, if you'll be away at expected time of delivery.


We guarantee to ship plants that are in prime condition for growing. If your order is damaged or fails to meet your expectations, we will cheerfully replace or refund it. Please contact our Customer Service Department at 1-800-503-9624 or email us at [email protected]. Please include your order number or customer number when contacting us.
