As Proven Winners® introduces new varieties it is
important to help you understand a little more about each of the new products.
This will begin a series of tips that will offer helpful hints to have even
greater success with our new varieties -- direct from the trial managers at
Proven Winners.

Superbells (TM) Calibrachoa

Superbells are neither as tall as Million Bells® 'Terra
Cotta' and 'Cherry Pink' nor as prostrate as Million Bells 'Trailing Blue' and
'Trailing Pink'; instead, they mound on top of the pot and then trail over the
sides. Production for Superbells is similar to other calibrachoas.

The pH should be kept between 5.5 and 6.0. Superbells 'Coral
Pink' and 'White' are the most sensitive to problems with pH or EC. Two hundred
ppm fertilizer constant liquid feed should be used with an extra weekly
application of 510 ppm fertilizer for mature, large containers.

Negative DIF can be used to control height with day temperatures
in the 60s and night temperatures in the high 60s. Plants can be held at
45-50° F. Pinches should not be necessary after transplant, however,
hanging baskets can benefit from a light pinch.

A 4-inch pot should finish in about four weeks from a liner.
Superbells 'Coral Pink' may need up to one week extra to finish. Superbells are
responsive to Sumagic.

Superbells are not day-neutral but will all be in bloom by
mid-April, with White needing the longest days to bloom. Under long-day
conditions they will all bloom at essentially the same time.

Superbena (TM) Verbena

Superbena are very vigorous, disease-tolerant verbena
varieties.

The pH should be kept between 5.5 and 6.0. Two hundred ppm
fertilizer constant liquid feed should be used with an extra weekly application
of 510 ppm fertilizer for mature, large containers. Negative DIF can be used to
control height with day temperatures in the 60s and night temperatures in the
high 60s. Pinches should not be necessary after transplant; however, hanging
baskets may benefit from a light pinch. A 4-inch pot should finish in about
four weeks. Superbenas are responsive to Sumagic and other plant growth
regulators 'Burgundy' and 'Coral Red' may be slightly more compact and may
require less growth regulator.

Symphony Osteospermum

The two new colors 'Peach' and 'Vanilla' can be produced the
same as all Symphony Osteospermum. The pH should be kept between 6 and 6.5. Two
hundred ppm fertilizer constant liquid feed should be used with an extra weekly
application of 510 ppm fertilizer for mature, large containers. Negative DIF
can be used to control height with day temperatures in the 60s and night
temperatures in the high 60s. Pinches should not be necessary after transplant;
however, hanging baskets may benefit from a light pinch. Sumagic is effective.
