Gardening, soil and plants

Light gardening is usually fine outside the low-count days, with gloves and closed footwear, provided you are not digging in compost or handling manure. During the low-count window it is better left to someone else.

The concern is not the plants. It is soil. Soil, compost and rotting plant matter carry fungal spores, and a suppressed immune system deals with those far less well than a healthy one. Fungal chest infections from inhaled spores are uncommon and genuinely serious.

Why this is worth a page

Because it is one of the few precautions almost nobody is told about. People are warned about crowds and raw food and never about the compost heap, and gardening is exactly the kind of gentle activity someone is encouraged to keep doing.

Soil and decaying plant matter are where certain moulds live. Disturbing them — digging, sweeping, turning compost, tipping out a bag of potting mix — throws spores into the air, and those spores get breathed in. In a healthy person nothing happens. With a suppressed immune system, they can occasionally take hold in the lungs.

It is uncommon but it is serious

This is not a common complication, and it should not frighten anyone out of their garden for six months. It is worth knowing because it is avoidable with gloves, damp soil and staying away from compost, and because the symptoms — a cough and a fever — look like something ordinary.

Cuts and scratches are the other half

Soil-contaminated wounds are a separate and more familiar problem. A thorn scratch or a nick from a tool during the low-count days is exactly the kind of small break in the skin that becomes an infection. Gloves prevent most of it.

Why a cough after gardening is worth mentioning

The symptoms of a fungal chest infection are a cough, breathlessness and a fever — indistinguishable from the ordinary chest infections that are far commoner. Teams treat the common thing first, which is correct. What changes their thinking is knowing you were turning compost last week, because that moves an unlikely diagnosis up the list. Say it unprompted; nobody will think to ask.

The same logic applies indoors

Repotting a houseplant on the kitchen table raises the same dust in a closed room. Bagged potting mix is often the dustiest thing in the house. Hand that job over, or do it outside with the soil damp.
