The island bush poppy is well adapted to sunny garden locations on well drained soils and with low amounts of supplemental water during summer. The chart shown below provides a recommended baseline guide to the monthly irrigation schedule and volume of supplemental water needed to maintain healthy growth throughout the average year. It should be noted there are several months indicated by an asterisk (*) when winter rains can provide sufficient moisture and irrigation is not needed. The high and low range of moisture indicates it can grow with varying amounts of water; more water in the spring will result in a longer flowering season.

Grows primarily in the cool season. Normal lighter prunings are not necessary if everything is looking good, but light thining or shaping can be done after blooms finish for the season, to avoid cutting off flowers or flower buds (which would likely happen if done earlier) (5,S). If plants are looking ragged or have poor form, they can be cut back by up to half in the late fall, once weather cools. Pruning toward the beginning of this window will preserve more of the spring / summer blooms the following season, by giving the plant the most growth time to develop new flowering branches after the cut back (18,S).
