How do I know if my hydrangeas will turn blue?
Only hydrangeas of the Hydrangea Macrophylla, which includes Lacecap and Mopheads, and Hydrangea Serrata varieties can be manipulated to change flower color, and some cultivars of those varieties are more capable than others.
For other varieties such as: Endless Summer, Nikko Blue, Penny-Mac, Nantucket Nikko, Blue Danube, Blue Wave, Blauer Prinz, etc. it is best to check plant tags for type and color-change capability.

How much time is needed for the product to work is dependent on the starting soil’s type and pH. If applied prior to bud development, results may be visible with the next bloom. The product will continue to release for up to 3 months. If applied in spring, a second application can be made later in the season. No more than 1 – 2 applications per year is recommended.
If the hydrangea plant is growing in heavily alkaline soil, it may take a growing season, or even longer, to adjust the pH of the soil to the point of getting blue colored blooms. The ideal pH for blue hydrangeas is 5.2 to 6.4. For severe alkalinity It may even be necessary to amend the soil with other products.
