Nepeta sibirica 'Souvenir d'André Chaudron' should be watered regularly to keep the soil slightly moist. It prefers evenly moist soil but does not tolerate waterlogged conditions. The plant should be watered once a week and in dry periods, increase the watering to 2 to 3 times a week. Make sure to water the plant deeply, ensuring it receives at least an inch of water. In regions experiencing periods of intense heat, additional water may be needed. Monitor the plant to ensure it does not dry out.

Nepeta sibirica 'Souvenir d'André Chaudron' is a full-sun loving plant species. It prefers 6 to 8 hours of direct sunlight per day for best growth and flowering. During summer months, some partial shade in the afternoon can help the plant to avoid intense sun and heat from burning the foliage. During winter months, the sunlight requirements for this species are lower with only 4 to 6 hours of sun a day being sufficient.

Nepeta (Nepeta sibirica 'Souvenir d'André Chaudron') can be pruned back in late winter and early spring to encourage bushier growth and keep it looking tidy. If pruning is needed to remove any old-growth or dead stems, it is best to do so in early spring before it begins to flower. At this time, simply prune back around 1-third of the plant to control size and encourage new growth. Pruning can also help to promote more compact growth and increase flowering. In late summer or early fall, after flowering has finished, prune any dead or damaged stems. This will help the plant to focus its energy on producing more flowers next season.
