Care Instructions for Pandorea jasminoides ‘Rosea’:

Light Requirements: Pandorea jasminoides ‘Rosea’ flourishes in full sun to partial shade. It flowers best when exposed to full sun but can tolerate partial shade, making it versatile for various garden settings.

Watering: Maintain evenly moist soil, especially during the first growing season to establish a robust root system. Once established, water as needed to keep the soil slightly moist but avoid waterlogging. Reduce watering during the winter months.

Soil: The Pink Bower Vine prefers loamy, well-drained soil that is rich in organic matter. It can tolerate a range of soil types, including slightly alkaline, clay, sand, and acidic soils. The ideal soil pH is slightly alkaline to neutral.

Fertilizing: Feed the plant during the growing season with a high-potash fertilizer, such as tomato feed, to encourage prolific blooming. Apply fertilizer fortnightly for best results.

Pruning: Regular pruning helps control the size and shape of the vine. Prune back after flowering to promote dense growth and to keep the vine manageable. It can be pruned hard if necessary, as it resprouts from heavy wood.

Support: Provide trellis, arbor, or other support structures to encourage climbing. The twining stems will quickly cover the support, creating a lush, green backdrop adorned with beautiful pink flowers.
