Planting two seasons in a row in the same soil
I have a raised bed garden box that I have planted tomatoes in last season. Do I have to do anything to the soil this season or can I just plant tomatoes in the box again this year and just fertilize?
Plant nutrients are used by the plants and some are leached from the upper soil profile with rain and irrigation. So it's best if you re-charge with a soil test based Rx for amendments. Or if that is not practical or affordable for your small garden box, use a mineral rich and balanced general purpose fertilizer product.
In addition to the fertilizer, or if you don't do anything else, incorporate (dig in) a copious amount of real compost.
