Where do scented pinks go in the winter? 

They're not like swallows they don't gather and leave for the winter but they do sort of hibernate.  As the days shorten the number of flowers they produce slowly decreases until the plants are effectively dormant. We take down the plastic covers on the low tunnels that cover some of the crop. This stops the plastic being ripped in winter storms and means it has a longer life span. The first year crop is just left in the field. The odd random flower head on a short stem sometimes appears giving a little flash of colour but apart from that there is just low silver green foliage. The second year crop is ripped out and replaced. This might seem a little extreme if you have pink plants in your garden that have happily kept flowering for years but for commercial production. we see a significant drop in yield after two years. The old plants and coir are emptied out of their tubs and temporally stored in the corner of field, later this will be rotavated into our bulb fields which improves the quality of the soil. The old tubs are washed out and then used again when the next crop of pinks is brought in from the nursery.
