Selecting the Right Nasturtium Variety
Choosing the appropriate nasturtium variety sets the stage for a successful garden. Opt for compact varieties for small spaces and trailing varieties for hanging baskets.
Choosing the Ideal Planting Location
Nasturtiums thrive in well-drained soil and full sunlight. Select a location that receives ample sunlight for most of the day.
