Container gardens really benefit from a little extra attention come springtime. In addition to last season's plants having used up many nutrients, winter rains and snow filter through pots and planters and carry away the nutrients that were left behind - leaving you with depleted soil that has little to offer. But you can recharge soil with ease. New plantings will struggle to access proper nutrients unless we gardeners intervene and 'feed' the soil!

Though you might be tempted to toss the existing soil out and start fresh, that’s not necessary. With a little love, care and almost no time, these containers will be ready for your favorite vegetables or flowering plants to shine.

  • Turn compost or fertilizer into the existing soil to add back in some much-needed nutrients. Be sure that fertilizer, which can burn roots, is turned in deeply enough so that growing roots won't come into contact with it right away.
  • Now comes the fun part! Choose your favorite flowering plants,vegetables and herbs to re-plant your containers for this season.
