Opinion...Disproportion in risks and returns

Opinion... Act now to mitigate climate change

Opinion... Image update for horticulturists

Opinion... How science can open up markets

Opinion... Good science vital for horticulture

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".

Pest & Disease Factsheet - White mould

Sclerotinia sclerotiorum, S. minor and S. trifoliorum particularly affecting legumes such as green, broad and faba beans.

Dixon on... Progressive innovation

Horticulture is typified by innovative thinking. Leaders in change are producers of fresh produce propelled by cost reductions and price stagnation.

Dixon on...Benefits of seaweed extracts confirmed by latest science

Seaweed extracts are valuable promoters of biocontrol. They stimulate benign soil and foliar microbes, which help repel plant pathogenic bacteria and fungi.

Dixon on...Urgent need to put agriculture back at the heart of policy

Titles mean a lot. When Defra was formed in 2001, "agriculture" was deleted from its title. Environment, food and rural affairs were then fashionable terms. Agriculture, in the widest sense including horticulture, was politically very unfashionable. Hence Great Britain became one of very few countries where the essential rural industry and dominant formative landscape force was lost.

According To Dixon ... Invest in science now or pay the price later

Our world is green. Coniferous forests, prairies, tropical rainforests and the smallest backyard gardens are all green because plants contain chlorophyll. This substance is the framework in leaves and stems where water and carbon dioxide are turned into life's building-blocks. It is outlined in school textbooks. Processes that construct natural materials require energy. Here it comes from sunlight in the process of photosynthesis.
