I suspect it’s a combination of genetic history – these cloves were reprogrammed not to divide as usual – and growing conditions, where something caused a change in the cell division process and the bulbs did not divide as expected.
This isn’t terribly helpful in trying to prevent it happening again and all I can suggest is that you start with fresh cloves, specifically grown for planting out. Don’t overfeed the soil before planting, but otherwise do as you normally have done in previous years.
Our tomatoes went all bad and mottled. What was the problem?

AI fear that your tomatoes had succumbed to blight – a fungus that destroys plants from late summer onwards. If it happens again, dispose of infected plants by burning them or burying them deeply. There are no chemicals to control this disease.
Next year, get growing blightresistant kinds. Two very healthy newcomers are ‘Crimson Crush’, a tasty, large fruited form, and ‘Primabella’, a delicious high-performing cherry type.
