blue passionflower

Blue Passionflower (Passiflora caerulea) should be watered moderately, about once a week in the summer months and every other week in the winter months. The soil should be kept slightly moist but not too soggy. The amount of water depends on the temperature, the size of the plant, and the type of potting soil you use. Ensure the soil is well aerated to prevent root rot. In summer, water the plant once a week with approximately 2-3 cups of water. In winter, water the plant at most every 2 weeks with up to a cup of water. Always check the soil for moisture before watering and adjust accordingly.

Blue passionflower requires full sun for best growth and flowering, which is defined as at least 6 hours of direct sunlight per day, with more light being better. Blue passionflower does best when provided with long days of sunlight during the summer months, but it will tolerate some short days during the winter.

Blue passionflower should be pruned twice per year, once in mid-spring and again in late summer. Pruning in spring should be done to shape the overall structure of the vine, while pruning in summer should primarily be done to keep growth in check and to reduce the possible spread of disease. When pruning blue passionflower at these times, it is important to remove up to 1 third of the shoots and about 15-20% of the older branches. Pruning any more than this can risk damaging the plant and stunting its growth.
