Pink bower vine, known botanically as pandorea jasminoides rosea, is an evergreen perennial flowering vine with a climbing growth habit. It is a sub-tropical species grown for its profusion of pink flowers that bloom from the early summer through early winter and its deep glossy green foliage. Pink bower vine is hardy in USDA Zones 9 through 11 and thrives in a full sun exposure with consistently moist and very rich soil.
Plant or transplant your pink bower vine into nutrient rich soil that has been amended with compost, well aged manure and peat moss to give the plant and roots a strong start. If the vine is already planted in average or relatively poor soil scratch in a few pounds of amendments into the top inch or two of soil and water in well. This will boost the long term quality of the soil and allow the nutrients to percolate down into the soil during watering and rainfall.
Fertilize your bower vine just once a year with a commercial slow release granular fertilizer with a balanced formulation. Apply the slow release fertilizer in the late winter or early spring in a dose recommended by the label directions. Always apply the fertilizer to the soil around the base of the plant to out past the drip line. Scratch the grains into the top inch or so of soil and water in deeply.
Feed your pink bower vine with a chemical fertilizer formula once a month throughout the main growing season from spring through to the end of fall. Dilute the liquid or crystal fertilizer with water at the dose recommended on the product label. Apply around the base of the plant from the crown out to just beyond the drip line. Refrain from pouring over the plant as it can cause the glossy foliage to spot or burn in the sun.
