Children in this group will receive services within the scope of the routine treatment and nursing care protocol of the clinic during hospitalisation. No intervention will be applied to the control group of this study until the discharge process takes place. However, on the day of discharge, the children in the control group and their parents will be informed about the garden activities by the researcher. A single session gardening activity will be planned according to the request of the child and parent. During this session, children will be given the opportunity to choose a plant and a pot, and then planting, watering and creating a name card will be carried out.

Children in this group will have three sessions of gardening activities within the scope of the 'Gardening Activities Programme' during their hospitalisation. The sessions will take place only with the active participation of the child participant and the researcher (EB); there will be one child participant in each session. The duration of the sessions will be between 30-45 minutes. The sessions in the 'Garden Activities Programme' regarding the session planning of the activities to be carried out with children are as follows.

Session 1: Pot Preparation and Plant Selection Session 2: Creating a Plant Arrangement Session 3: Care and Illustration

When we look at the studies evaluating the effect of gardening activities on hospitalized children; it is seen that mostly children's opinions about therapeutic gardens are included and studies involving active gardening activities are limited. Shao et al. (2020) gave hospitalized children a task about garden plants and made them full this task through active participation and mobile games. However, it is seen that the gardening activity applied in this study was limited to a 5-minute task. The most important difference of our study from these studies is that a standardized gardening activity program will be applied to hospitalized children during their hospitalization and the active participation of the child will be ensured.

Child Anxiety Scale-Dispositional (CAS-D): The Child Anxiety Scale-State (CAS-D) is shaped like a thermometer with a bulb at the bottom and horizontal lines with intervals going upwards. To measure the child's state anxiety, the child is asked to tick 'what he/she is feeling at the moment'. The score can range from 0-10. A high scale score indicates that the child's anxiety is increasing.

Psychosocial Symptoms Diagnostic Scale for Hospitalized Children: The scale consists of 24 items and five sub-dimensions (anxiety, hopelessness, communication difficulties, anger and aggression, regression). The scale has a 3-point likert-type scale, 'never: 0, sometimes: 1, often: 2'. The score obtained from the scale varies between 0-48. A high scale score indicates that the child hospitalized in the clinic has psychosocial problems.
