Swedes and Turnips
Both of these crops are best sown directly into their final position. Similar in appearance, turnips are smaller than swedes. They also tend to have a whiter flesh and be smaller and rounder than swedes.Turnips are best harvested when they are slightly bigger than a golf ball.

Remember, the larger the variety the more space the crop will need. Properly spacing the plants prevents them from becoming stunted or deformed. If space is at a premium, try sowing or transplanting seedlings as other crops are harvested. This means that any gaps in your vegetable beds are plugged by your swede or turnip plants
