One of my neighbors gave me some Crocosmia bulbs. I want to plant them but I don't know if I should separate what he gave me or plant the whole thing as one. They look like there are individual bulbs attached to each other stacked vertically. He wasn't sure either. I will try and attach a picture.

Dear JM,

You can separate the bulbs by twisting them and plant about 18 inches a part.  Crocosmia is a hardy and vigorous plant and will multiply those bulbs in the years to come.  They can also grow very large, sometimes 2-3 feet wide depending on the variety and about 3 feet tall. 

Your picture came through and the bulbs look fine.  Do not use a knife as you could cut into the bulb.

Add some composted manure or regular compost to the planting site for some extra nutrients.  Once planted, mulch the top of the soil with some compost.

They like full sun and good drainage.  Hummingbirds love them.

If you have any further questions, please contact us again.
