As a guideline, water this plant once every 2 weeks.

Nepeta 'Six Hills Giant' plants need about 6 hours of direct sunlight a day in order to thrive. They do best in a location that receives full sun in the morning and then partial shade in the afternoon. However, make sure that the area they are planted in does not get hit with strong winds or hot afternoon sun, as this can stress the plant. It is best to provide the plant with shade from a tarp in the afternoon to protect it during extreme heat. In winter, it is wise to move the pot to a spot that receives some sun to prevent the plant from becoming too dormant.

When pruning Nepeta 'Six Hills Giant' it's best to prune the plant after it has finished blooming, usually in mid-summer. To keep the plant neat and tidy, it's a good idea to prune out spent flowers and dead wood. Remove up to 1-third of the stems at the base of the plant. Make sure you keep some of the stems that are flowering or have young buds. This will ensure that the plant will grow well and have plenty of healthy growth. Depending on the desired size and shape of your plant, you can prune it more severely, removing more stems and dead wood.
