The Q&A Archives: Watering

Question: I have a St. John's Wort planted in a pot on my front porch. It is yellow/green/pink verigated. The foliage is beautiful. And the flowers are wonderful. What are the telltale signs of underwatering/overwatering? I would like to get the flowers to last as long as possible.


Answer: Hypericum, or St. John's Wort loves sunshine and slightly dry soils. Water thoroughly, then allow the top half inch of soil to dry out before watering again. If the plants are not getting enough water they will refuse to grow; too much water will result in leaf edges turning brown. To encourage more flowers, cut the stems back after the flowers fade. This will encourage the growth of new flowering stems.
