I would like to use bread crumbs, oat cereal (dry), As fertilizer and compost mix with coffee grounds(dry).
I would also like to add uncooked rice into the soil.
At this moment I intend to work on getting healthy soil so that next spring in April or May I will plant bulbs and/or flower seeds.
What to you think about using these dry food As both compost and fertilizer.
No one took care of the soil for several years.
Good for you to want to improve that neglected soil. Your plants will be grateful. However, the additions you suggest really will have no value in nourishing the soil and may attract pests. There are many excellent organic fertilizers and amendments you can use, though. Just visit our Gardening Guide section here and see several guides on improving your soil.
