The invention relates to aerating devices for flower pots, vases or window boxes. It comprises internal pots (2) which may be circular, made of porous or fibrous materials or waterproof with holes 3, in which case they will be covered on the inside 8 with rotproof synthetic materials or fine plastic mesh 9. The internal pots are kept at a certain distance from the wall 6 of the outer waterproof pots 7 by means of reliefs of variable design 5, or polyhedral ridges, or by construction. The air circulating between these two pots or these double walls improves the respiration of the plant's roots and the biological behaviour of the culture substrate. This substrate may also be directly aerated by means of tubular chimneys of porous or fibrous materials or waterproof materials with holes, being hollow in structure, or made of a compressed biodegradable chemical substance. <IMAGE>
