Watering

I have a raised bed containing a row of carrots, a row of parsnips and 3 fruit bearing tomato plants. I use watering cans as I haven't got a long enough hose but I'm not sure how much give them. Suggestions please xxx

a) do I need to put in drainage holes / liner?
b) have heard these veg all need different quality soil - how can that be in one Planter?
C) was linked to watering as it seems from this article that they all need different amounts at different times - again how can this work in one planter?
basically any help / suggestions on where to start would be great and am I aiming too high?
Growing crops like that in a planter is a bit impossible in my opinion, brassicas need nitrogen rich soil, packed down very firmly, carrots need poorer unfertilised soil, softly packed.
Then whatever you grow, you need to do it on a three year cycle, so I would stick to just one type of veg. I wouldn’t think about brassicas in a planter, they are really best in the open ground, but they are very good for salad stuff, so go for lettuce, onions and radishes. You can grow those all year without worrying about crop rotation. You can sow a couple of tomato seeds next March.
Decide on what you want to grow [and eat] and research the requirements for each plant, then see which ones will grow best together in your planter. It'll also depend on the size of planter you have, but salad crops like lettuce and rocket will grow well in ordinary sized pots and troughs. For instance - something around 1 foot/30cm diameter will give you a few plants of each of those
