Answer: The best way to increase the water holding capacity of a sandy garden bed is to add organic matter. This can be in the form of animal manures, compost or even a green manure drop. In the case of animal manures, compost and grass clippings you should make sure that the material is well composted. This eliminates problems such as nitrogen draw down, introducing pests and pathogens and it should kill any weed seeds present. When adding these to the garden you should dig them in to at least one spades depth. Mulching the top of the garden bed will also help to add organic matter as it breaks down while also helping the plants.
Green manure crops are a cheap and effective method of adding organic matter to your garden. You can buy seed mixes for green manure, you simply plant them out, wait until you start to see flower heads form, then cut them down and incorporate them into the soil. This method is slower than simply adding organic matter into the soil although it can be useful when trying to improve a large garden bed.
Using organic based fertilisers such as Yates dynamic lifter will also add organic matter to the soil as it breaks down.
