greater periwinkle

Greater periwinkle should be watered once a week with approximately 1 inch of water. The amount of water poured at each watering should depend on the soil; if the soil is sandy, more water will be needed than with loam or clay. Before watering, stick your finger in the soil and gauge the moisture level. If the soil is dry to the touch, it is time to water. If the soil feels damp, you can wait a few more days before watering.

The greater periwinkle plant species thrives best in full sun, meaning they will require at least 6 hours of direct sunlight per day to grow healthily. Such conditions are especially important during the warmer months when the sun is strongest and the days are longest. In areas with the hottest climates, greater periwinkle plants may need some afternoon shade to help protect them from too much direct sunlight. During the winter months, greater periwinkle plants can still benefit from natural sunlight, but they may not need as much as they do during the summer months. Make sure to position the plant in a way that it is not as exposed to the cold winter winds and is still able to receive direct sunlight throughout the day.

Greater periwinkle (Vinca major 'Wojo's Gem') should be pruned once a year in early spring, when new growth begins to emerge. Pruning helps to keep the plant neat and promote more vigorous flowering. Cut back shoots to just above the lowest pair of leaves; this encourages branching and more blooms, as well as producing a bushier, more attractive, and more manageable plant. Removal of dead, damaged, and crossed branches, as well as thinning interior growth, all help to maximize blooms.
