Planting, sowing surfinia
How to plant surfinia
It is recommended to plant this petunia in spring, after any risk of freezing is over, because it doesn’t survive freezing well.
- Surfinia in flower beds
Blend garden soil to soil mix.
- Surfinia for pots, garden boxes, containers
If you’ve purchased your plants in nursery pots, mix together garden earth and soil mix.
It’s also possible to use only soil mix, since this would further boost plant growth and blooming.
- Surfinia as a hanging plant
Choose hanging plant soil mix which tends to be lighter, otherwise you’ll have problems with this type of planting.
- For seeds, practice sowing in a tray indoors, in your home, starting in February/March.
Simply press the seeds down to ensure they stick to the special “seedling soil mix”, without covering them over.
Water regularly to retain moisture, but not too much.
When the first leaves of your surfinias pop out, transplant to nursery pots and wait for the last frost to have passed before planting them outdoors.
Whether the plant is in a container or in the ground, select a sun-filled spot for maximum blooming.
Pruning and caring for surfinia
To enhance flower-bearing, you can remove wilted flowers regularly.
During spells of high temperatures, feel free to water in the evening to avoid having your petunia dry out.
- It is preferable to let the ground dry up somewhat before watering again to avoid excess moisture.
