I recently planted several vines in containers in full sun as directed. Now I’ve noticed the leaves appear to have a purple cast to them. What might be wrong?
Signs of stress caused by improper pot size, insufficient nutrients, soil, water, weather conditions, site incompatibilities or drainage can by themselves, or in combination, cause color change in plant leaves. Some plants with dark green leaves that are prone to leaf burn can develop color changes in their leaves if they are receiving too much light. The opposite is also true if they do not receive adequate light. Then again there are plants that have naturally occurring color changes in their leaves and the color is not indicative of a plant problem. With the wide selection of hybrids available, it is not a surprise that we find it difficult to figure out if the coloring is genetic or not.
Annual and perennial vines are easy-to-grow plants if you have a basic knowledge of their cultural needs. Some key facts pertaining to raising vines in your garden: Select varieties that will thrive, not just survive, in the garden. Site conditions to consider include light, water, weather and soil. Most vines like well-drained, organic-rich soil that will support their fast growth rate. Once the vine develops a good root system, stress will be kept to a minimum. Container-grown plants should be watered and fed regularly with a balanced fertilizer. Don’t postpone installing the vine’s support system; they love to hold on. Mulch helps to keep in moisture and cool the root system. Pruning should include removal of diseased or damaged stems. A perennial vine requires removal of dense, tangled growth to allow air flow for healthy growth, while annual vines require little pruning except for shaping.
