Dahlia Merluza Bulb

€2.50 EUR

Dahlia Merluza is characterised by brilliant golden yellow and deep orange semi-cactus flowers measure up to 8” across. The large flowers are produced in profusion on vigorous plants that create a scene in the late summer garden. Perfect for the herbaceous border or in a bed of their own! 

Planting Guide:
  • Planting period: April-May.     
  • 10 cm of soil on top of the bulb.   
  • Spacing 40 cm.         
  • Flowers from July until the first frost. 
  • Height 80 cm.

Half-hardy. Perennial. These bulbs cannot withstand freezing conditions or sitting in water. It is best to start the tubers in pots first, pot size needs to be around 4 ltr. Place the pots either in the greenhouse or somewhere that is frost-free. Once growing and free from cold weather then plant out into the garden. If you have well-drained soil, plant them deep and cover in the winter with mulch.  Feed well throughout the growing season with a slow-release fertilizer. If your soil is heavy it is best to lift the tubers at first frost, cut the stems back leaving an inch. Store upside down in a frost-free environment, replant in April. Propagation: Divide the bulbs every couple of years.

There's no need to water the soil until the dahlia plants appear; in fact, overwatering can cause bulbs to rot. After dahlias are established, provide a deep watering 2 to 3 times a week for at least 30 minutes with a sprinkler (and more in dry, hot climates).
