  1. Unit 9: The Interior Landscape

  2. Objectives Define the terms. Describe the proper way to water plants. Discuss the amount of light that plants need. Discuss the best temperature for optimum growth. Describe the type of soil mixture that is needed for plant growth. List other concerns for interior plants.

  3. 1. Terms Interior plantscaping: the selection, installation, management, maintenance and design of plantings within buildings as well as the effects of interior plants on people and the environment. Acclimatization: the adjustment of an outdoor plant to interior conditions.

  4. 1. Terms Light quality: color of light emitted by a particular source.

  5. 2. Proper Way to Water Plants • Watering: • You must carefully observe each plant and how many times you water it. • Signs of improper watering are: • Drooping leaves • Wilting leaves • Yellow leaves You will also need to look at the moisture control, and if there is proper drainage.

  6. 2. Proper Way to Water Plants • There are different ways in watering plants: • Drench and let dry: water is added and then the soil is allowed to dry out until you water again. • Drench and let dry slightly: water is added and the soil is allowed to dry slightly and then water again. The soil will be moist when you water again.

  7. 2. Proper Way to Water Plants • The last method of watering is: • Keep medium constantly moist at all times so it is moist to the touch.

  8. 3. Amount of Light Needed • Lighting: -Photosynthesis is the process of converting light energy to chemical energy and storing it in the bonds of sugar. 6 CO2 + 6 H2O + photons→ C6H12O6 + 6 O2 - Photons = light energy.

  9. 3. Amount of Light Needed • What is Light Meters? • small machines that measure illumination or light. You can find these at florists, garden centers and department stores.

  10. 3. Amount of Light Needed • There are three groups of light intensity: • Direct sun: plant should receive full intensity of natural sunlight. • Partial sun or weak sun: plant should receive less than 50 % of natural light • Indirect or filtered light: plant should receive no direct sunlight at all.

  11. 3. Amount of Light Needed • Artificial Lighting - Fluorescent light enables horticulturalists to: • Take root cuttings of interior plants more easily • Start seeds of new and different interior plants • Grow tropical plants, cacti and succulents with greater ease

  12. 4. Best Temperature for Growth • Temperature: • The recommended temperature for indoor plants are between 50 - 85 degrees F.

  13. 4. Best Temperature for Growth • Humidity: • The percent of moisture in the air, which is an important factor to consider when growing interior plants.

  14. 4. Best Temperature for Growth • Humidity: • Humidity around interior plants can be increased by: • Spraying a fine mist of water on the foliage of the plant with an inexpensive plastic spray bottle or any type of mister. • Use a watertight tray filled with small pea gravel to hold the potted plants. Water is added to the tray to come to the top of the gravel and plants are set on the gravel, making certain that the pots are not actually in the water.

  15. 4. Best Temperature for Growth • Humidity: • Use a humidifier to provide the moisture in the air. • Place plants in a part of the house that has high humidity. Examples: bathroom & kitchen

  16. 5. Soil Mixture for Growth • Soil Mixture: • A good general potting mixture includes two parts loamy soil, one part organic matter, such as peat moss, & one part course sand and horticultural grade perlite.

  17. 5. Soil Mixture for Growth • Fertilizers: • There are two types of interior plant fertilizers on the market today: • Slow release which is in the form of small beads that are coated with plastic and dissolved over a period of time and is applied to the soil mixture. • Soluble fertilizer is available in liquid or solid form. When using the solid form, it must be dissolved in water before applying to soil.

  18. 6. Other Concerns Air pollution Dust Pruning Repotting Insects & disease Vandalism & abuse
