FAQs
How long does it take for Nepeta seeds to germinate?
Germination usually takes between 7 and 21 days, provided seeds are kept consistently moist and at the recommended temperature of 16-20°C.
What is the best position for Nepeta cataria?
This plant prefers a sunny position but will also tolerate semi-shade. It requires free-draining soil.
How tall does the plant grow?
Thompson & Morgan Nepeta Cataria typically grows to a height of up to 90cm.
How far apart should I plant them?
Plant the seedlings out approximately 30cm (12in) apart.
Will cats eat the plant?
Yes, Nepeta cataria is famously attractive to cats and is often referred to as catnip. They enjoy the scent and may chew on the leaves.
Can I grow this in pots?
Yes, after initially potting into 8cm pots, they can be grown in larger containers or planted directly into garden beds and borders, provided the soil is free-draining.
Does this plant need special care in winter?
Autumn-sown plants might benefit from overwintering in a coldframe. Established plants are hardy perennials and generally overwinter well outdoors in well-drained soil, dying back to the ground and regrowing in spring.
Troubleshooting
Seeds are not germinating
Ensure seeds are kept consistently moist and are at the correct temperature (16-20°C). Try covering the seed tray with a plastic lid to maintain humidity. Be patient, as germination can take up to 21 days.
Seedlings are weak or leggy
This can be due to insufficient light or overcrowding. Ensure seedlings receive adequate sunlight and are transplanted into individual pots once large enough.
Plants are not flowering
Ensure the plant is receiving adequate sunlight (at least 6 hours per day). Catnip generally flowers well in full sun. Avoid over-fertilizing, which can promote leaf growth at the expense of flowers.
Plants dying back in winter
As a hardy perennial, Nepeta cataria is expected to die back to the ground in winter. Ensure roots are protected by mulching and that soil is well-draining to prevent rot. New growth should emerge in spring.

Setup, Compatibility & Care
Sowing: Sow seeds in spring to autumn in good, free-draining seed compost, lightly covering the seeds. Maintain temperatures of 16-20°C for germination, which typically takes 7-21 days. Alternatively, sow in spring directly into a well-raked, moist seedbed where plants are to flower.
Transplanting: Once seedlings are large enough to handle, transplant them into 8cm (3in) pots. Grow them in cool conditions before final planting out.
Planting Out: Space plants 30cm (12in) apart in a sunny spot with free-draining soil. This plant thrives in full sun or partial shade.
Overwintering: Autumn-sown plants should be overwintered in a well-ventilated coldframe and planted out in the spring.
Care: Ensure the soil is free-draining. Water regularly during dry periods, especially when plants are young and establishing. Deadhead spent flowers to encourage further blooming. Cut back established plants in early spring to promote fresh growth.
