Spring through Summer Finish. Standard PPP.
Pinch once, 1-2 weeks after transplant. PGRs are not necessary on Sweet Caroline and Illusion varieties.
General pest and disease practices as listed in notes. Watch for aphids and white flies. Thrips and spider mites can be problematic, scout and treat as necessary. Thrips are especially prevalent on chartreuse colored Ipomoea. Spider mites are especially problematic on Tricolor.
Under high humidity and low light conditions, Oedema (syn. Intumesence) causes small bumps to form along the leaf veins. It is caused by the roots absorbing more water than the leaves can release. It usually resolves itself within a few weeks when light levels are higher and circulation is better.
Prolonged wet foliage can lead to bacterial leaf spotting. Copper based fungicides will treat for this problem.
Illusion varieties are more compact and are better suited for combinations with less vigorous varieties. They also work well in landscapes.
Sweet Caroline Bewitched is more upright and compact than the other Sweet Carolines and is the best choice for small pot production.
In low light conditions avoid wet soil and moisture on the foliage.
