Transcript

  • 1. RHS Level 2 Certificate Spring and summer bedding and summer and winter containers.
  • 2. Learning Objectives <ul><li>1.5 Name FIVE plants suitable for spring bedding displays, including TWO bulbs (or corms or tubers). </li></ul><ul><li>1.6 Name TEN plants suitable for summer display in containers or hanging baskets. </li></ul><ul><li>1.7 Name FIVE plants suitable for winter display in containers or hanging baskets. </li></ul><ul><li>1.8 Describe the soil or growing media preparation, sowing or planting out of plants for seasonal display for the situations listed in 1.5 – 1.7. </li></ul><ul><li>1.9 Describe the routine maintenance of seasonal bedding, including control of weeds and common pests and diseases (aphids, slugs and snails, vine weevil, grey mould, powdery mildew) for the situations listed in 1.5-1.7 </li></ul>
  • 3. Spring bedding <ul><li>Plants used need to be hardy, robust and colourful. </li></ul><ul><li>Bulbs e.g. Tulipa fosteriana ‘Red Emperor’ and Narcissus ‘February Gold’. </li></ul><ul><li>Hardy perennials that are grown as annuals are useful. E.g. Wallflowers (Chieranthus cheiri ), Forget-me-not ( Mysotis sylvatica ) and double Daisy ( Bellis perennis ‘Pomponette Series’). </li></ul>
  • 4. Planting bulbs as bedding <ul><li>In Autumn, need well drained soil with good levels of organic matter. Plant Tulips in November, Daffodils in October. </li></ul><ul><li>Plant to 2-3 times the depth of the bulb and 2-3 times its size apart. </li></ul><ul><li>Keep weeds down over winter and early spring. </li></ul><ul><li>Do not cut off the leaves after flowering or tie up. </li></ul><ul><li>Lift and dry to store – or grow in large pots and sink into soil </li></ul><ul><li>Feed and water after flowering. </li></ul>
  • 5. Bulb pests and diseases <ul><li>Squirrels dig up and eat bulbs. Firm soil after planting, chicken wire barrier. </li></ul><ul><li>Narcissus fly – mulch, firm soil around bulbs after flowering, discard affected bulbs. </li></ul><ul><li>Stem and bulb eelworm – see previous notes. </li></ul><ul><li>Fungal diseases – storage rots. Discard mouldy bulbs, fungicide powder on stored bulbs. </li></ul>
  • 6. Planting spring bedding <ul><li>Grow Wallflowers (Chieranthus cheiri ), Forget-me-not ( Mysotis sylvatica ) and double Daisy ( Bellis perennis ‘Pomponette Series’) in nursery bed sowing late spring/summer. </li></ul><ul><li>Move to final position in Autumn. </li></ul><ul><li>Water in dry spells. Weed by hand. Deadhead Bellis . Remove after flowering. </li></ul>
  • 7. Spring bedding pests and diseases <ul><li>Aphids </li></ul><ul><li>Cats and birds attack/dig up seedlings </li></ul><ul><li>Vine weevil – Polyanthus </li></ul><ul><li>Slugs and snails </li></ul><ul><li>Grey mould if very thickly sown </li></ul><ul><li>Powdery mildew – if under water stress, Mysotis particularly prone to this. </li></ul>
  • 8. Containers - summer <ul><li>Watering is a major concern – use water retaining gel and a drip irrigation system. If not then water daily in hot weather. </li></ul><ul><li>Slow release fertilizer in compost and feed weekly once that runs out. </li></ul><ul><li>Deadhead to encourage more flowers. </li></ul><ul><li>Most plants used for seasonal display are half-hardy or tender – so may need to keep in greenhouse after planting until May. </li></ul>
  • 9. Hanging baskets <ul><li>Vulnerable to drying out and wind damage. Use water retaining gel. </li></ul><ul><li>Put in sheltered spot that gets some shade. </li></ul><ul><li>Water daily or use drip irrigation system. </li></ul><ul><li>Feeding as for containers. </li></ul><ul><li>Use combination of upright and trailing plants for best effect. </li></ul><ul><li>May need to keep in greenhouse until May. </li></ul>
  • 10. Winter containers <ul><li>Put on pot feet and add good layer of crocks and grit for drainage. </li></ul><ul><li>Choose suitable container – most terra cotta is not frost resistant. </li></ul><ul><li>Watering – check even if rain has fallen. </li></ul><ul><li>Feeding – not required. </li></ul><ul><li>No water retaining gel – risk of water logging. </li></ul><ul><li>Remove any dead flowers or damaged leaves to avoid fungal problems. </li></ul>
  • 11. Containers – pests and diseases <ul><li>Vine weevil – unlikely to be a problem with summer seasonal displays, but if winter containers are left planted they can cause problems. </li></ul><ul><li>Aphid </li></ul><ul><li>Grey mould </li></ul><ul><li>Powdery mildew </li></ul>
  • 12. Learning outcomes <ul><li>1.5 Name FIVE plants suitable for spring bedding displays, including TWO bulbs (or corms or tubers). </li></ul><ul><li>1.6 Name TEN plants suitable for summer display in containers or hanging baskets. </li></ul><ul><li>1.7 Name FIVE plants suitable for winter display in containers or hanging baskets. </li></ul><ul><li>1.8 Describe the soil or growing media preparation, sowing or planting out of plants for seasonal display for the situations listed in 1.5 – 1.7. </li></ul><ul><li>1.9 Describe the routine maintenance of seasonal bedding, including control of weeds and common pests and diseases (aphids, slugs and snails, vine weevil, grey mould, powdery mildew) for the situations listed in 1.5-1.7 </li></ul>
