Many people plant winter garlic, as it allows them to harvest earlier and, in some ways, simplifies care.
However, it is important to understand that it cannot be planted after any crop.
After which an experienced gardener will not plant winter garlic
The garlic itself
This would be a very bad idea: at best, the garlic would grow small and not very tasty. It is important to remember that garlic is not planted in the same place two years in a row.
Roots
Any plants in this category will be bad predecessors for winter garlic. Due to the peculiarities of "extraction" of nutrients, the bed will be too poor and depleted.
Other plants
Some plants can make the bed attractive to a number of pests that are dangerous to garlic. Therefore, the winter garlic harvest will be at risk.
For example, beds after strawberries and wild strawberries are bad options. You shouldn't plant garlic after tomatoes.
Onions will also be a bad predecessor.
