| Cultivation:
Petunia 'Prism Sunshine' is a Grandiflora Petunia. It is the
best performing Yellow Petunia.
All Petunias
are broken down into classes or groups. Grandiflora's have the
largest flowers... usually up to 4" across. They can be
either single or double flowered. Their flowers are easily damaged
by rain... lately that hasn't been a problem around here. Some
say that Grandiflora's are best planted in sheltered beds, in
mixed containers or hanging baskets that can be moved or sheltered
from rain. Nearly all Petunia's are easy to grow and quite vigorous growers.
Plant Petunia Prism Sunshine in full sun in any well worked soil in either containers
or beds. Space plants 6" to 12" apart depending on how
quickly you want the area to fill in. Plants can be sheared after
the initial flowering to maintain bushiness and promote new flower
growth... or they can be left un-sheared to grow naturally. Feed
monthly with a liquid fertilizer.
Potential pests ~ diseases: Aphids or whiteflies.
