How to Grow Amazing Peonies
Peonies are one of the most sought after perennials. They have vibrant colors and an intoxicating fragrance. Added onto this, they can thrive almost anywhere and some varieties can even survive in extreme winter conditions. If it is well taken care of with the proper nutrients, peonies can survive and continue to bloom every year for a hundred years or more
Ideal N-P-K Ratio
Peonies are heavy feeders that benefit from regular fertilization. 10-20-20 and 10-10-10 fertilizers are good options for peonies. You want to avoid fertilizers with too much nutrients as these may cause dense foliage rather than promoting the beautiful blooms that you want.
Fertilize your peonies first thing in the spring. You’ll want to spread the fertilizer around the perimeter of the plant, but avoid the crown of the peony as this can cause damage to the peony.
Ideal Growing Environment
Peonies thrive in environments where they are receiving lots of sun (which encourages blooms) as well as good air circulation. You want to plant it in soil that drains easily. These conditions will help prevent the most troublesome disease that peonies face – Botrytis. Botrytis, or gray mold, is a fungal disease that thrives in moist conditions. The best way to control this disease is to prevent this disease by controlling the environment. You’ll also want to shelter it from strong winds and plant it away from other trees or shrubbery so that your peonies are not competing for nutrients and moisture.
Again, I recommend buying the Osmocote’s fertilizer. Don’t make the mistake of buying any average fertilizer at your local gardening store. Many of them will simply not produce the same results. You cannot go wrong with any of the fertilizers above.
