Large Peony Tubers
Larger tubers with three to five eyes may
flower the second year after planting; those with less than three
eyes can take three to five years to mature enough to bloom at all,
or bloom as well as you would like.
also fail to bloom if the tubers are planted too deeply. They should
be planted so that the eyes are no more than 1 inch below the soil
surface. Too much shade can keep peonies from blooming or blooming
heavily. They flower best in full sun and need at least six hours of
sun a day to perform well. In addition to the shade cast by trees
and shrubs, their roots may compete with your peonies for water and
Best Peony Soil
best in a well-drained, loamy soil with a pH (acidity or alkalinity)
between 6.5 and 7.0. Peony tubers can rot in poorly drained soil.
Soil fertility can also impact how well peonies bloom. You should
fertilize peonies annually, preferably based on soil test results.
It is best to use a fertilizer that has a low to moderate amount of
nitrogen, such as the product you used this spring. Excessive
nitrogen can cause peonies to produce all foliage and few or no
are labeled with the analysis -- the numbers on the container that
indicate the percentage of nitrogen, phosphorus and potassium
(potash) the fertilizer contains. The nutrients are always listed in
same order. Be careful to avoid getting fertilizer granules on the
foliage or crown of the plant because the salt content can burn
Finally, we did
have a few hard frosts after your peonies were up and growing. It is
possible that the small buds you see are not growing and developing
because they were killed by frost.
