EFFECT OF PEAT TYPE AND FREQUENCY OF WATERING ON POINSETTIA

Christmas-flowering poinsettias were grown singly in 12.5-cm plastic pots.
Plants grown in wood fen peat were nearly as vigorous as those grown in the standard sphagnum peat compost and hadas high a nutrient status.
Observations conducted afterwards in centrally-heated rooms indicated that peat type had no effect on plant longevity.

There was a greater increase in growth of plants in wood fen that. in sphagnum peat when the frequency of watering was increased from every fifth day to daily during the bright weather conditions in autumn 1969 and 1971. However, frequency of watering had little effect on plant growth in either compost during the dull weather conditions in autumn 1970.
