Product Details

Now you can grow beautiful, healthy Hydrangeas without using harsh chemical soil additives. Fast-acting and completely organic, Soil Acidifier will turn your Hydrangea flowers from pink to deep, vivid blue. It works naturally to lower your soil pH to the perfect range for producing those fabulous blue blossoms. Soil Acidifier is approved for organic gardening and contains 100% natural minerals that won't burn your plants. It's an ideal organic fertilizer for acid-loving Blueberries too.

  • 6 lb bag
  • For established Hydrangeas, sprinkle 2½ cups evenly around the base of the plant in spring and water well. Reapply every 2 months until desired bloom color is achieved. For new plants, apply 1¼ cups.
  • For Blueberries, sprinkle 1 tablespoon evenly around the base of each plant at flowering time in spring and water well. Reapply every 2 months until desired pH is achieved. (a pH of 5.5 is ideal)




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.
