One of the trickiest things to accomplish in the vegetable garden, I think, is a continuous supply of vegetables every day of the year. It seems like it would require substantial forward thinking if you want to grow everything from seed. I have been growing vegetables since I was about 18 but only in recent years have I been able to put the time into thinking about the sowing of seeds regularly enough to provide us with almost everything, almost all of the time. Now, though, I have found that it is really not that hard. (The beautiful garden in this photo belongs to Maggie and Bob and is genuinely the best display of perfection in a vegetable garden I have ever seen! I took this photo on Friday).
One thing I have learned is not to sow too many seeds at once! I get a foam box and either fill it with cubes of soil with the soil blocker or without. Sow one row only and thinly of each of several types of vegetables. Of course you can do this in the garden if you prefer. Label them well with a waterproof marker. Once the seeds have germinated and are ready to plant out they will be close to a month old. So, sow some more of the same or different seeds. If you sow a boxful of seed every month, preferably on the full moon, I reckon you would just about have the right amount for a small family. Maybe, with things like lettuce you should do it every 2 weeks, if you eat a lot of salads. You can adjust it month by month or year by year as you get the hang of it. I often sow a lot more than this, sometimes a whole box of one thing, so I have plenty of seedlings to give away. It is always nice to have extras for friends.
The second thing to take into account is how you are going to make room for it all in the vegetable garden with some coming in and some coming out all the time. I mostly manage this by raising seedlings in the foam boxes which gives space to the garden for the month or so they are germinating and getting big enough to plant out. In winter I can fit lots more into the same garden area because I don't have to worry about only having plants along the dripper lines - I plant things right up to the edges of the paths and in beds rather than rows, often tall things like fennel interspersed with lower stuff like lettuce, that can take a bit of shade even in winter.
The third thing is how to keep enough fertility in the soil to have everything growing well all the time. This is hard, I think. If you are harvesting stuff everyday you are removing all those nutrients all the time. I know some people do it differently but what I usually do is make my own compost and use this often. Add something to the soil each time I plant into it - eg Manutec blood and bone, Alroc rock dust, or some Rapid Raiser (organic pellets made locally from chicken manure).
At the moment this is what I have happening in my garden, more or less :
I am planting out - broccoli, kale, lettuce - several sorts (we eat lots of salads), beetroot, leeks,
I am sowing: see the list in the side bar for what I sowed a couple of weeks ago.
I am harvesting: Asian greens (bok choyish stuff, cabbage, mustards), lettuces, spinachy things, spring onions, kale, celery, last of the capsicums (surely!), parsley, other herbs, a few daikon seed pods, fennel flowers and fronds, nasturtiums (leaves and flowers), sorrel.
I am about to harvest: Chinese sea shells, water chestnuts, sweet potatoes.
I have growing in the garden for harvesting in the future: fennel, lettuce, spinachy things, kales, spring onions, broccoli, celery, Asian greens of various sorts, chicory, peas (sugar snap, Deb's purple), chervil, coriander, mizuna, broccoli, parsnips, carrots, shallots, garlic.
Obviously, as the seasons change you have to sow different things, but if you keep to sowing one box every month, it will be a good start. I hope other people will be able to add their knowledge to this rough guide, in the comments.
