Summary

This week, we’ll be checking in on the health of our gardens, taking a look at the various diseases on the rise here in the UK and what we can do to stave off their encroachment. But that’s not all! With the return of allergy season, we’re also going to explore the many ways we can garden with not just the health of our plants in mind, but with that of our own bodies, as well. Plant Pathologist Dr. Liz Beal chats with us about the RHS annual disease rankings, Dr. Shubha Allard and Dr. Patrick Yong take us through the allergies to watch out for this spring, and finally virologist Dr. Tim Wreghitt shares his advice on building a low-allergy garden.

0:40.3	And the organism that infects them is a funny little creature. It swims through the soil moisture.
0:45.3	And it gets to the roots and then infects them. And so it's much worse in warm, wet years.
0:51.3	And most allotments will have this disease because those spores that it
0:55.1	releases when those swollen clubbed roots break up and rot in the autumn can last for up to 20
