PURPOSE:To obtain a water holding agent, consisting of a hydrous gel of a water absorbing resin, capable of remarkably enhancing preserving effects on cut flowers and providing admiration of the cut flowers useful in the interior for a long period and having a high gel strength and excellent shape holding property of the gel without a fear of water leakage. CONSTITUTION:A water holding agent consisting of a hydrous gel of a water absorbing resin, preferably a crosslinked material of a partially neutralized polyacrylate capable of providing hydrous gel having excellent water holding property, having preferably >=0.5mm particle diameter of the water absorbing resin in aspects of handleability and air permeability and, if necessary, wrapped in an air-permeable reinforcing material capable of absorbing a large amount of water and swelling in water to form a hydrogel. The above-mentioned hydrous gel is formed simply by adding an absorbing resin to water and stirring the water and may be obtained merely by adjusting the amount of water so as to provide a swelling ratio of the water absorbing resin to water corresponding to 5-95% based on the saturation swelling ratio. Cut flowers may be directly inserted into the hydrous gel and arranged. Furthermore, the agent can be utilized for curing of cuttings, layering and graftings.
