Peonies
are among the most anticipated summer flowers, with buds opening into glorious
pink or crimson flowers. If you see peonies with bud blast, you will surely be
disappointed. When your peony flowers wither in the bud, they may be suffering
from bud blast of peonies. Read on for information about what causes this and
how to prevent it.

Bud Blast of Peonies

Peonies with bud blast start off with normal flower
development. However, it doesn’t last very long and the buds
don’t develop into flowers
. When the buds are still small, they turn brown
or black and wither.

Experts used to say that this condition, termed bud blast of
peonies, was caused by botrytis
blight
, a fungal disease. Now it is recognized that these problems with
peonies are often caused by improper cultural care.

What Causes Peony Bud Blast?

When peony buds don’t develop, you can still assign the
problem the name of bud
blast
. This term describes the symptoms rather than a disease or pathogen.
Any time peonies do not get the growing conditions they require, it can result
in bud blast.

One factor that causes bud blast of peonies is getting inadequate
irrigation
during dry periods. Other primary causes are not enough sunlight
or too little nutrition.

Peonies with bud blast can also be caused by too
little potassium in the soil
, sudden drops in temperature while the buds
are developing, overcrowding, and overly deep planting. Root
nematodes
are another potential cause, as is botrytis blight.

How to Prevent Problems with Peonies

Given that these problems are most often the result of
environmental stresses, the gardener can take steps to prevent them. The best
way to avoid bud blast is to provide your plants with good growing conditions.

Take care when you select a site for your peonies, making
sure to provide the plants with sufficient sun and organically rich,
well-draining soil. Peonies do best with regular irrigation and fertilizer.
Mulch well in the winter to protect the plants from sudden freezes.

You’ll also do well to keep an eye on the plants and divide
them when they start getting too crowded. Good air circulation as well as sun
exposure prevents fungal issues.
