Sowing Guide

Early Sowing/Module Sowing

Thinly sow polyanthus seeds on the surface of damp compost in trays, modules or pots.
Firm the seeds into the surface of the compost. Do not cover. Do not exclude light as this will help with germination however avoid direct sunlight.
Place the container in a clear polythene bag and seal or if preferred place in a propagator. High temperatures can hinder germination.
When the seeds start to germinate move to an area with a reduced temperature and good daylight exposure. Protect from frost.
As soon as the young seedlings are large enough to handle transplant into 7 - 10 cm pots.
Grow on in a cool frost free location, a greenhouse or cold frame is ideal.
Plant out in September - October where they are to flower the following year.
Harden off over 7 - 10 days before planting out to reduce shock.
If after 25 days the seeds have still not germinated, place the container in a polythene bag and seal and leave in a fridge for 2 - 3 weeks. After this time return to the propagator or warm location. This will simulate a cold wintery spell and will break the dormancy of the seeds.

Direct Sowing

For best results start the plants indoors.

Growing On

Water the newly planted polyanthus plants well until established.
Do not allow the roots to dry out, water frequently especially in dry conditions.
Cut back when the flowering season has ended.
Apply a mulch in autumn and spring, this will help prevent the surrounding soil from drying out.


To keep the plants productive and to avoid overcrowding, lift and divide the plants every 2 - 3 years in early spring.
