Opinion... How science can open up markets

Revitalisation of our glasshouse industry is welcome. Development of Thanet Earth and now the project at Bamford, Ipswich, are factory-level growing.

Opinion... Good science vital for horticulture

The 8,000-plus papers published in The Journal of Horticultural Science & Biotechnology (JHSB) over the past 100 years chart discoveries that innovators have converted into valuable technological businesses.

Opinion... Soil health key to weather defence

Britain enjoys and hates its weather. Our Atlantic highs and lows usually deliver periods of rain or sunshine. Occasionally, the jet stream shifts, providing intense Arctic cold or southern European heat.

Opinion... Bridges needed across the sectors

Horticulture Week's careers guide (HW, April 2018) is a revealing insight into what constitutes "a horticulturist". Horticulture is a coherent discipline.

Opinion... Get rid of plastics in Horticulture

Blue Planet II eloquently showed the rich tapestry of life in the oceans. It also focused public awareness on plastic pollution damaging wildlife.

Opinion ... Answering call for home production

Whitehall wants more home production of fresh produce. That's very welcome. Horticulture is a can-do industry and will react positively. In ramping-up production, increases in basic resources are needed. Seed suppliers want advance warning by at least one season of higher demand.

Opinion... System must support home produce

Continuous food supplies are cornerstones of social well-being. Even minor blips like last winter's disruption of fresh produce supplies from Iberia become "media disasters".
