Cactus Dahlia White and Bright
Bright & Breezy Dahlia
- My Dahlias have been flowering early and successfully since the beginning of July. The white cactus plants are the most forward with the collarettes just starting.
- I no longer leave the plants in the ground over winter as I have lost too many tubers to rot in the wet conditions we get in Yorkshire.
- I store tubers in old pillowcases in the garage. Plastic bags would cause fungus and rot.
- I divide up the tubers in early spring. Some are easy to divide thus increasing stock. Other clumps of tubers need cutting into pieces all with a neck left on from last year. New growth comes from the neck not the tuber itself.
- I start off the tubers in plant pots but I am too lazy to take cuttings which I am told would make stronger plants.
Dahlia Cut Flowers
- There are as many cut flower tips as there are dahlia species. Dahlia are meant to be long lasting in a vase.
- Keep your cut dahlias out of the sun and out of the heat.
- Pick early in the day as with most cut flower.
- Choose blooms that have started to unfurl – neither tight buds nor fully open.
- Place the Dahlia stems in hot tap water then allow them to cool for an hour.
- Use fresh water when arranging then change it every couple of days.
- Remove any foliage from the stems to avoid it decaying in the water.
Garden tips
- Cut back to encourage more stems and deadhead to encourage more blooms
- Water well and regularly
- Stake taller varieties
- Give dahlias plenty of room
