decorative blooms. This variety is an excellent choice for summer-shaded
programs and spring crops. It is a mid-vigour variety, very flexible and
adaptable to any size container. It sizes up very well in the north, has good
colour retention and excellent shelf life. ‘Allegra Yellow’ was one of customer
favorites from last year open house in Ontario.

This early season variety needs to be planted by mid-June to allow enough
time for vegetative growth. If exposed to cold temperatures in early stages,
plants could initiate flower buds prematurely and flower short. To prevent early
budding, unrooted cuttings need to be stuck under long days and kept warm above
68˚F in propagation area.

‘Allegra Yellow’ is a heavy feeder. Shortly after transplanting when
irrigation frequency is lower, plants require high rates of 300 to 400 ppm from
20-10-20 or similar type fertilizer with each watering. At the time of flower
initiation, growers should switch to nitrate-based, potassium-rich fertilizers
and continue until flower buds are ready to show first colour. All new 2010
Belgian Mum introductions are no-pinch varieties.
