Time release versus water soluble fertilizers. Whether you use time release or water soluble fertilizer for flowers, vegetables, trees or shrubs is a matter of personal preference and what you are willing to pay.A 3-pound container of Osmocote four-month time release for flowers and vegetables costs about $12 (Lowes) and covers about 120 square feet.ime release fertilizers may be in loose granular form or as a spike that is inserted into the ground. Each form gradually disintegrates, releasing nutrients with rain water.
