When and how can I thin spring bulbs?

Asked April 27, 2015, 11:52 AM EDT

I planted too many spring bulbs in too small an area last fall. When is the best time to dig up some of them and move them to another area? Many thanks.

If bulbs have become crowded or need to be moved to another site, move only after the foliage has faded. They need to store nutrients in the bulbs for next season. Divide bulbs carefully by digging up the entire clump. Separate the bulbs and replant them in other locations.

You can also move in the fall after the foliage has disappeared. However, you should use some sort of location marker in the spring so that you can locate the bulbs in the fall.
