How to grow Nasturtium

Nasturtium

Pull off old flower heads to prevent seeds forming. This will make more buds and reduce self seeding. Fortunately, if you don’t want to grow nasturtiums the following year in the same ground, the seedlings, with their round leaves are very easily identifiable.
Sometimes it is necessary to cut back the stem tips if they begin to take over.
