FAQs
When is the best time to plant Viola 'Delft Blue'?
These are best planted in early spring or early autumn when temperatures are moderate.
Can these be planted directly into the garden?
It is recommended to pot them up first to let the root system grow stronger before moving them to the final garden bed.
Do these violas need full sun?
They prefer full sun to partial shade; they will bloom best in a location with plenty of morning light.
How many plants should I put in a container?
For a 12-inch container, 3 to 5 plugs will provide a nice, full display.
Are these plants hardy?
Violas are generally hardy, but it is best to protect young plug plants from severe, late-spring frosts during their initial growth phase.
How often should I feed them?
Applying a liquid fertilizer every 2 to 3 weeks during the flowering season will keep them performing at their best.
Troubleshooting
Plants are wilting shortly after planting
Check soil moisture immediately. Plugs have small root systems and need to be kept moist while establishing in their new pots.
Lack of flowers despite healthy foliage
Ensure the plants are receiving at least 6 hours of sunlight and that they are not overcrowded, which can lead to poor flower production.
Slow growth after potting
Ensure you are using fresh, nutrient-rich potting compost and that the plugs are not being buried too deep in the soil.

Setup, Compatibility & Care
Upon receiving your 24 plug plants, they should be potted up into small pots or trays using good-quality potting compost immediately. Keep them in a well-lit, frost-free location until the root system has developed and the risk of harsh frost has passed. Once established, harden them off before transplanting them into their final garden position. Ensure your chosen soil or compost is well-draining, as violas do not appreciate sitting in waterlogged ground. For maintenance, water regularly during dry spells and feed with a balanced liquid fertilizer every few weeks to support their intense blooming habit.
