Peony Tips for June

Peony Tips for June



Sping was a long time

coming this year. As a result it now looks as though

few Peonies will be in bloom north of the Potomac and

Ohio Rivers before June. Attention is called to the

May Peony Tips, many of which are also applicable to


Cultivate often enough

to keep weeds down and the soil loose. Water in abundance

is necessary for the finest bloom and proper plant development.

Remove all faded blooms

promptly. Do not allow seed to mature unless you need

it. Trim the plants back slightly to make them more

presentable in the summer garden, but never cut them

down to the ground until late fall.

Choose varieties now.

Blooming time is the best time to select varieties

for fall planting. Visit one or more good Peony collections.

Choose the types, colors and habits you like best and

buy accordingly. New varieties have been introduced

by the hundreds in the past twenty years. Many improvements

have been made in singles and Japs. Better colors, better

habits and better bloomers have come.

Insects do little damage

to Peonies as a rule. Ants visit the buds because of

the honey they exude, and they sometimes carry disease.

Borers occasionally enter a stalk and cause it to collapse.

Damage is usually done before we know the borer is there.

Rose bugs in infested communities do much damage to

blooms. Use any remedy you may know. Thrips destroy

many blooms, especially the very double late flowers.

Diseases take their toll

sometimes. Prevention is the best cure. Clean grounds

and cultivation do more than chemicals to prevent trouble.

Use occasional sprayings of Bordeaux to be on the safe


When leaves wilt. Watch

your plants and if you see leaves wilting, don’t wait

until they discolor and die, but find out the cause.

It may be just lack of water. If so, supply it. A mole

may have burrowed under your plant and left it suspended

in his burrow. Investigate, fill the burrow, and destroy

the mole, if possible. One of several root rots may

have attacked your plant. Examine the root and if it

shows signs of disease, dig the plant, cut out all diseased

parts, disinfect the root with formaldehyde, a quarter

of a cup to 3 gallons of water, leaving the root in

the solution for two or three hours, and plant in fresh

soil. Burn the diseased parts of the root. If the plant

is very badly affected or an inexpensive one, burn it.

Leaf spot. Several

kinds of leaf spot may appear, which Bordeaux will prevent.

Diseased leaves should be removed and burned, if they

are not too numerous, but do not cut down the leafage

too much as these spots do not permanently injure the

plant unless they take complete possession of it. Be

sure to burn all leaves and stems in the fall. Small

oval spots often come on the stems, but they are not

fatal. Crowded plants and smothering with weeds are

the most frequent causes of diseases of leaves and stems.

These causes are easily removed.

White fungus. Often

in dry weather a white fungus-like growth will spread

over the roots. This is said not to be dangerous. It

was much in evidence last year. But it does affect the

stems and crowns, making them look like rotted wood

of a yellowish hue. Again the only remedy is good cultivation

and treating infected roots if you wish with the formaldehyde

or bichloride solutions.
