Cover for nesting birds Colourful display – appealing to members Ground cover plants Screening Windbreak Used for planting in a border eg. around the clubhouse or by a tee Climbers on the clubhouse Time of year for planting shrubs 1. 2. Normally plant shrubs in Spring Sometimes plant shrubs in Autumn depending on what type e.g.Barberry Planting depth for shrubs 1. Nursery Depth 2. Container depth Immediate aftercare of shrubs 1) Watering 2) Mulching 3) Feeding Watering a. First 2 years will need lots of watering b. Once established will require less c. d. Perforated hose gives steady application of water Water in morning or late evening Mulching 1) Keeps soil moist during dry periods 2) Keeps soil surface cool on hot days 3) Keeps annual weeds under control 4) Mulches provide nutrients to shrub Feeding a. b. c. Gives newly planted shrubs a kick start eg. bone meal Give shrub a boost in spring when coming out of winter period Shrubs with larger flowering heads need more nutrients than others General shrub aftercare 1) 2) 3) 4) 5) 6) Weed control Winter Protection Cutting and dead-heading Pruning Feeding Cultivating and leaf removal Weed control a. b.

Only severe winter may damage shrubs Base of shrub covered with straw Plastic screen can protect from severe frost Cutting and Dead heading a. b. Cutting blooms for arranging indoor displays Deadheading – keeps shrub tidy and allows new flowers to grow Pruning a. b. c. To remove unwanted growth from woody plants To shape the shrub as required To regulate the amount of blossom or fruit prodution Digging over and leaf removal a. b.

State names of 10 shrubs State the uses of shrubs on a golf course State depth of planting of shrubs State immediate aftercare for shrubs State general aftercare for shrubs State common pests that affect shrubs Plant spacing for most shrubs 1. 2. 3. Add the mature height of Shrub A and Shrub B together Divide answer by three Gives you typical planting space between the two shrubs Four types of planting material 1. Container grown 2. Bare rooted 3. Balled 4. Pre-packaged Container grown a. Most convenient way to buy shrubs b. Can plant all year round c. Expensive d. Can be left unplanted for weeks if kept moist Bare-rooted a. Popular way to buy deciduous shrubs b. Planting between October and March c. Dug up at nursery with soil removed d. Less expensive than container grown e. Can be left unplanted for 3 to 4 days Balled Type a. b. c. d. Popular way to buy evergreen shrubs Suitable for planting in September, October and April Dug out of nursery – soil ball wrapped in hessian sacking or nylon netting Can be left unplanted for weeks if kept moist Pre-packaged a. b.
