Terra Nova has been a world leader in the introduction of new and premium perennials. We have been asked to write a short piece on maximizing the shelf-life of the plants including cultural tips and a good soil recipe.
Soils Starting from ground-zero, let's talk soils.
A good soil mix is the key to all of this. Fertilizers Perennials are NOT annuals. Soluble applications in the 250ppm-300ppm rate may be tolerated occasionally but we prefer a very mild 75 to 100ppm. We all know that too much lush growth will inhibit flowering and create a plant that is more difficult to maintain. For most perennials, a moderate growth rate with firm foliage is preferred.
