Exploring Horticulture Concepts

What are the main methods of plant propagation?

• Propagation methods include only soil and water.

• The main methods of plant propagation are sexual propagation (seeds) and asexual propagation (cuttings, layering, division, grafting, and tissue culture).

• All plants can only be propagated by division.

• Plant propagation is only done through seeds.

Describe the process of seed germination.

• Seeds grow into flowers before germination.

• Seed germination occurs only in spring.

• Seed germination is the process where a seed absorbs water, activates enzymes, and grows into a seedling.

• Germination requires exposure to direct sunlight.

What is the importance of soil pH in plant growth?

• Higher soil pH always leads to better crop yields.

• Soil pH is crucial for nutrient availability and overall plant health.

• Soil pH is only important for certain types of plants.

• Soil pH has no effect on plant growth.

List three common soil amendments and their benefits.

• Silt: Improves soil texture but has no nutrient benefits.

• Clay: Retains moisture but can lead to compaction.

• 1. Compost: Improves soil structure and fertility. 2. Peat Moss: Enhances moisture retention and aeration. 3. Lime: Raises soil pH and provides calcium.

• Sand: Increases drainage but reduces fertility.

How can organic matter improve soil structure?

• Organic matter improves soil structure by increasing aggregation and enhancing aeration and water retention.

• Organic matter has no effect on soil aeration.

• Organic matter decreases soil fertility and structure.

• Organic matter makes soil more compact and dense.

What are the signs of nutrient deficiency in plants?

• Signs of nutrient deficiency in plants include yellowing leaves, stunted growth, necrotic spots, and poor fruit development.

• Large fruit size

• Bright green leaves

• Rapid growth

Name three common pests that affect garden plants.

• Snails

• Aphids, spider mites, whiteflies

• Caterpillars

• Ladybugs

What are integrated pest management strategies?

• Integrated pest management strategies include monitoring, biological control, cultural practices, judicious chemical use, and promoting beneficial organisms.

• Ignoring pest populations completely

• Planting only one type of crop

• Using only chemical pesticides

How can crop rotation help in pest control?

• Crop rotation only benefits soil health and does not impact pests.

• Crop rotation increases pest populations by providing a consistent food source.

• Crop rotation helps in pest control by disrupting pest life cycles and reducing pest populations.

• Crop rotation has no effect on pest control and can worsen infestations.

What are the key principles of landscape design?

• Functionality, durability, maintenance, cost-effectiveness

• Simplicity, chaos, randomness, isolation

• Symmetry, contrast, texture, color, harmony

• Balance, unity, proportion, scale, rhythm, focal points
