Perennials grow best in a loose well drained soil. Annual applications of manure in the fall can be dug in the spring to improve soil texture and retain moisture. Plants like to be watered on a regular basis and it is important to cultivate the soil frequently. The small fibrous roots systems grow best in a loose well-ventilated soil. Fertilizers should be applied annually.
Most perennials are best planted in the spring. Some grow best in the sun, others in shade. Plant perennials as soon as all danger of frost has passed, and the ground is dry enough to work. Make sure to give plants plenty of room so that none of the roots are crowded.
