It would be remiss of me not to recommend Gardeners' World Magazine, as we always include plenty of information on Growing Your Own, and evenb have a free packet of Tomato Maskotka seed coming with the April issue (along with free fragrant sweet peas).
We're also publishing a 'Grow Your Own' bookazine in March, along with an iPad version, which is looking stunning!
I agree that David Hessayon's Vegetable Expert book is one I regularly turn to, and usually has the advice (crop spacing, sowing time or depth, etc) that I'm looking for. Some of the seed company web sites also have very good 'at-a-glance' growing guides.
Was there any specific advice you can't find, Lisa?
