First – yes – you need to eat – so does the garden, Second – it depends. A container garden on a patio or balcony will need a lot more frequent feeding than a garden in a ground bed in rich organic soil. A garden in a ground bed in a newly turned bed of ‘subdivision’ soil may need more feeding than same garden after years of adding lots of organic matter every year. Third – then we get into the organic/natural/fertilizer topic. A little lesson in plant biology – plant roots take up ‘food’ only in a pure chemical form. If you add food in a complex form such as manure – the soil must first break down the organic compounds to their base chemical compounds before the roots can grab the goodies. That is one reason most farms and gardeners use some ‘chemical’ based plant foods or fertilizers – they work well. Now on bad side – if you use too much chemical foods you can burn the roots – or have the chemicals ‘run off’ into ground water. The secret to all of this is to be thoughtful and to something that works well for you. We actually recommend you consider BOTH types of feed. We are big on adding manures as they also help the soil – and we like using liquid plant foods through out the season as they really pick up the plants – also we can ad liquid feeds say after a week of heavy rain as we know the soil is leached clean of plant food. Another consideration is how often you want to add plant food. If you are a go out every night with a glass of Merlot and putter type – then adding a liquid plant food every 7-10 days will fit you – if you are more the look at the garden on Saturdays after soccer type – then consider adding a granular plant food that will stay in the soil up to a month.
