Dahlias Pots Collarette Alstergrusse
D4700
Description
Dahlia ‘Alstergrusse’ is a dwarf collarette dahlia, bearing masses of pretty citrus-orange cartwheels.
The vibrant, open-faced blooms smother neat foliage from July to October, shining out against a dark-green backdrop. Delightful in a tropical colour scheme with coral-reds and rich yellow tones.
This productive and petite dahlia is also perfect for patio pots and colourful summer containers.
Grown with taller varieties such as ‘Jive’ and ‘Honka Yellow’, ‘Collarette Alstergrusse’ will beam at the forefront of the border.
Care Guide
To grow Dahlias, select a sunny spot with well-drained soil, and dig a 30cm deep hole. Plant the tuber 10cm below the soil surface, spacing multiple tubers 45cm apart, or 90cm for taller varieties. Water consistently, maintaining moist but not saturated soil and protect new shoots from slug damage with eco-friendly methods. Feed plants during the blooming period with liquid plant food. Provide support for stems which will reach 60-90cm tall depending on variety. Enjoy spectacular blooms from late summer until first frosts. Cut or deadhead the flowers regularly for a continually flourishing display. Once blooming has finished, cut back foliage before lifting, drying and storing the tubers in peat-free substitute, in a frost-free place until the following spring.
