Chapter 24 — Root Rot
TAMSIN
Farah called at seven twelve on a Monday morning and began with the plants.
“Four cestrum cuttings,” she said. “All from the same Calder tray. Mixed symptoms, shared wet compost, held cool since Thursday. The network needs someone who knows the original plant.”
Tamsin stood beside the kettle in her flat, looking at rain strung across the kitchen window. The river forecast had fallen overnight, which meant Maeve could manage the school-site inspection without her. That was not the relevant calculation.
“Who has them?”
“They’re at the community greenhouse. Calder retained them only because nobody else had quarantine space. Transfer happens this morning.”
“Is Graham there?”
“For the handover. We asked for the person who authorised the old specification, not a driver with a form. He hasn’t asked who the specialist is.”
The kettle clicked off. Tamsin did not move to pour it.
“I’ll assess the plants,” she said. “He doesn’t get my number, my address, or a conversation outside the task.”
“I haven’t offered any of those.”
“And if I stop, I leave.”
“Yes.”
Tamsin watched water collect at the lower corner of the glass before the bead released and ran down the frame.
She could decline. Farah would find another path, though perhaps not before the rot reached the last living tissue.
The choice was hers precisely because nobody had disguised it as anything else.
“Send me the site gate code.”
The community greenhouse occupied a former council maintenance yard behind a row of garages.
Its plastic roof held last night’s rain in shallow hollows, and the western gutter discharged too close to the foundation.
Tamsin noted the dark strip along the blockwork before she saw Farah waiting inside the gate.
Three benches had been cleared. On the first stood the four cuttings in separate black pots, no longer sharing a tray. Clean knives, alcohol, labels and waste bags occupied the second. The third held crates marked for two satellite sites.
Graham stayed beyond them with the greenhouse manager. His charcoal coat over a white shirt was too formal for the damp yard and entirely familiar.
Her body supplied an old inventory before she could prevent it: the breadth of his shoulders, the small pale line beside his mouth, the way he held still when impatience cost him effort. She set her tool case on the clean bench.
“Conditions since isolation?” she asked Farah.
“Nine degrees at night, eleven by day. No misting. Roof vent open for two hours yesterday. Pots spaced thirty centimetres apart.”
“Water?”
“None.”
“Good.”
The word belonged to the work. Tamsin put on gloves.
Farah pointed to Graham. “He has the failure count and the authority to release the last Calder-held stock. Once that’s done, he goes.”
Graham looked at Tamsin without trying to hold her gaze. “Seventy-six confirmed dead. Forty-two doubtful at inspection. One hundred and nine viable. Two hundred and twenty-seven received.”
Exact figures. No softened survival percentage.
“Cause?”
“I cancelled the display project and left its growing specification active. Night heat rose to eighteen degrees. Humidity stayed above eighty percent, one fan failed, and the plants continued on the February schedule after there was no February garden.”
Facilities had failed to close the order; the excuse was available. Graham left it unused.
Tamsin turned to the pots. “Which losses were cestrum?”
“Six dead. These four doubtful. Three previously moved as viable to separate sites.”
“Source labels?”
“All descended from the south-wall plant, but from three collection dates.”
The first two cuttings belonged to the same group despite their different leaves. Rot had crossed both crowns. Tamsin bagged one whole pot and took a single clean tip from the other, small enough that nobody could mistake an attempt for a saved plant.
“The allotment co-op’s east bay, if they can keep it cool and ventilated,” she said.
Farah messaged the network. The tip waited on clean paper while the dead pot went into regulated waste.
Tamsin lifted the third pot. The leafless stem resisted a gentle scrape, living green beneath the bark. White roots remained on one side, while the other side had darkened where it pressed against the wet tray edge.
“This one can be washed and divided from the rotten mass. It needs a mineral-heavy mix and bottom ventilation.”
The greenhouse manager reached for the pot. At the same instant Graham moved one hand towards the wash basin, as if to clear the hose from her path.
Tamsin stopped.
It was barely a pause, nothing she would have named in another person. Graham saw it. His hand dropped before it crossed the bench line, and he stepped back until there was open floor between them.
“Farah?” he said.
Farah moved the hose.
Tamsin washed the roots over a sealed tub. Her pulse had altered, an inconvenient quickness beneath her gloves. Graham did not watch her face for an answer to the thing he had done correctly. He watched the floor beside the crates.
The root crown divided unevenly. Tamsin removed the blackened tissue, sterilised the blade and cut again until the section smelled clean rather than sour. One viable piece remained.
“Send it to the cooler western glasshouse,” she said. “No Calder compost, no capillary matting. Survival recorded at fourteen days, six weeks and twelve weeks.”
“Who receives the record?” the manager asked.
“The network list. Each keeper sees the condition data, not private addresses.”
Graham said, “Calder receives nothing unless the network sends it voluntarily.”
Tamsin glanced at him. The sentence stood without a bid for praise.
The fourth cutting was the dangerous one because it looked healthy. Four leaves, firm stem, a small fan of pale root at the drainage hole. When Tamsin removed the pot, she found the centre of the root ball warm and wet, with fine webbing across decomposing bark.
“Not clear,” she said. “The outer roots are alive. The crown may be infected.”
Farah came closer. “Can we treat it here?”
“We can reduce the load. We can’t prove it clean.”
She cut away the outer roots in stages, changing blades between each cut. Two inner roots remained white. The stem base held no lesion, but the shared conditions made certainty impossible.
“Two choices,” Tamsin said. “Destroy it now and protect the other holdings, or keep it alone for twelve weeks with a named person responsible for tools and drainage.”
“Which would you do?”
“Keep it, because the three viable ones are young and we don’t yet know whether they’ll establish. But not here. This house shares runoff between bays.”
Farah checked the replies on her phone. “Dinah’s cold frame is empty. She’ll take the pot if it arrives sealed and the bench stands over a catch tray.”
“Dinah is inland. Night temperature?”
“Six to eight.”
“Too low for a root-compromised cestrum. The riverside co-op?”
“Twelve degrees, manual vents, separate drainage. They’ll accept one plant, not both.”
“Send the rooted division there. The uncertain whole plant needs a different failure risk.”
The network placed the living attempts without a tour of every handover.
The rooted division went to Salma’s riverside co-op after she rejected a bench whose air moved towards her citrus.
Kareem took the green tip for his ventilated cabinet.
The healthy-looking whole plant went nowhere until a volunteer orchid room offered one isolated cabinet with separate drainage; untested private porches were not suitable for stock that might carry Pythium.
“The network covers the record,” Farah said. “Calder covers the electricity.”
The coordinator looked past her towards the doorway. “Is Calder agreeing to that?”
Graham followed only as far as the orchid-room threshold to complete the financial release. He remained outside the growing space.
“Yes,” he said from the threshold. “Electricity, disinfectant, and regulated disposal if required. No ownership or access follows payment.”
The coordinator named a maximum amount. Graham agreed without negotiating. He signed the supplier instruction on Farah’s clipboard, then handed the pen back to her rather than to Tamsin.
“That completes Calder’s transfer,” Farah said.
Graham looked at Tamsin once. Attraction moved through her as recognition rather than invitation, sharp enough to disrupt the motion of her hand towards the tool case. She let her hand rest on the latch.
The silence remained open.
“Goodbye, Tamsin,” he said.
He left by the service passage. A minute later, she heard the outer door close. No question followed him. No request reached Farah after he was gone.
Tamsin finished labelling the quarantine dates and showed the coordinator how to photograph the crown without moving the pot.
One descendant had become two living attempts held at different sites, one uncertain plant held alone, and two acknowledged deaths.
The numbers were worse than the campaign version would have been and more useful because they were true.
Outside, rain had begun again. It struck the greenhouse roof, flowed through three separate gutters and disappeared towards three different drains.
Farah zipped the contaminated tools into a red wash bag. “Do you want me to keep you off all Calder-related plant calls?”
Tamsin closed her case. The immediate answer would have been simpler. It would also have made Graham, rather than the plants, the organising fact.
“No,” she said. “If the network needs my judgement, ask me. Tell me who will be present and why.”
“And he can’t ask through us.”
“He can’t.”
Farah nodded and put the bag in her van.
Tamsin walked to her own car without checking whether Graham’s had gone. The task had ended, and so had his presence. For now, that distinction was enough to keep.
