The Q&A Archives: Portulaca

Question: I am trying to plan ahead for next years garden. In my garden now, I have Portulaca bordering each garden. I know that it re-seeds itself, however I'm not sure if I'm suppose to cut the existing plants back or am I suppose to leave the existing plant? I don't want the gardens to look bad by leaving the dead plant, but on the other hand, I don't want to pull up or cut back the plants and ruin my garden for next year.

Answer: Portulaca, or Moss Rose, is an annual plant that will self-sow and provide new plants next spring if you allow the flowers to develop seed pods. When these are dry the seeds will be expelled. Before removing your plants from the garden make sure they have finished blooming and producing seeds. At the very end of the season you can pull the old plants out. Next spring new plants will sprout in the same general garden area.
