Winter - get an early start on summer vegies
If you want to get an early start with your summer vegies, why not sow seeds into pots on a windowsill, ready for transplanting when the weather's warm enough? The kitchen windowsill right above the sink usually offers the position with the best chance of success as it's easy to keep an eye on the pots. This means there's far less chance of them drying out and they can be rotated regularly to receive even amounts of light.
Tomatoes, capsicums, chillis and, possibly, eggplants are some of the best choices for windowsill germination.
