Episode 167 advice sheet
What makes companion planting perfect for organic gardening (2:20)
Using chemical solutions to kill the bad bugs in the garden comes with the issue of killing the good bugs too, which is a fantastic reason to put your focus onto companion planting. Among the first plants worth a mention is the Tagetes family, perfect for growing around tomatoes and a rich, bold cut flower in its own right.
The perfect balance of tagetes to tomatoes (5:45)
For the average crop of tomatoes you’ll want to plant tagetes between each row, which means that somewhere between 6 and 9 flowers is ample protection for most.
If you have a huge packet of seeds and have some left over, remember that they can be stored in a dry, cold and dark place - that one packet could stand you in good stead for years to come.
Pairing salvias with roses (7:00)
The combination of roses with salvias is well documented, particularly for long time podcast listeners, and the standout variety that Arthur spotlights is the dainty, delicate but gorgeous ‘Nachtvlinder’.
Salvias aren’t hardy, so you’ll have to wait until May to put them out in the garden, but thankfully that’s the period that they’ll be called upon the most to protect from fungal diseases.
Basil as an edible and a companion plant (9:35)
Rather than simply warding off diseases and pests, Basil can be planted to attract pollinators too, making it a companion in the garden and the kitchen alike.
Along the lines of herbs, Sarah also shares the story behind a bed that’s been dedicated to Yellow Mustard - it’s said to be a wonderful soil fumigant, so we’ll keep an eye on its impact here at Perch Hill, which promises to be great for a bed that recently saw aubergine plants succumb to verticillium wilt.
