Question 1

During a site visit, students notice that one rooftop garden uses grow bags, while another uses clay pots.
i. List one advantage and one disadvantage of each container.
ii. Which one would you recommend for your school rooftop garden and why?

Accepted Answer

i. Advantages and disadvantages:
- Grow bags:
  Advantage: Lightweight and easy to move; good drainage.
  Disadvantage: May dry out faster and less durable.
- Clay pots:
  Advantage: Durable and provide good aeration to roots.
  Disadvantage: Heavy and can break easily.
ii. Recommendation depends on factors like weight restrictions on rooftop, ease of handling, and durability. For a school rooftop garden, grow bags may be recommended because they are lightweight, easy to handle, and reduce the load on the rooftop structure. — Grow bags are made of fabric or plastic and are light, making them suitable for rooftops where weight is a concern. Clay pots are heavier and can add more load. However, clay pots allow better aeration but are fragile. Considering safety and ease of use in a school environment, grow bags are preferable.

Question 2

You have prepared two potting mixes as follows:
i. Mix A: Soil + Compost + Cocopeat
ii. Mix B: Soil only

After one month, plants grown in the Mix A potting mix look healthier and are lighter to carry, while plants in Mix B pot are heavy and waterlogged.

Explain why Mix A is better for rooftop gardening.

Accepted Answer

Mix A is better because it contains compost and cocopeat along with soil. Compost improves soil fertility by adding nutrients and beneficial microorganisms. Cocopeat improves water retention and aeration, making the mix lighter and preventing waterlogging. Mix B, which is soil only, retains too much water, becomes heavy and waterlogged, which can harm plant roots. Therefore, Mix A provides better drainage, aeration, and nutrients, leading to healthier plants and is lighter to carry, which is important for rooftop gardening. — Compost enriches the soil with nutrients and improves soil structure. Cocopeat is a lightweight material that holds moisture but also allows excess water to drain, preventing waterlogging. Soil alone can compact and retain too much water, causing root rot. Hence, Mix A supports better plant growth and is suitable for rooftop conditions.

Question 3

A group of students noticed their tomato plants turning yellow despite regular watering. Later, they found out that the pots were waterlogged due to blocked drainage holes.
i. What went wrong?
ii. Suggest two preventive measures for the future.

Accepted Answer

i. What went wrong: The drainage holes of the pots were blocked, causing water to accumulate and waterlog the soil. This led to poor aeration of roots and root rot, causing the tomato plants to turn yellow.
ii. Preventive measures:
1. Ensure that drainage holes in pots are not blocked and allow excess water to drain out.
2. Use potting mix with good drainage properties and avoid overwatering plants. — Blocked drainage holes prevent excess water from escaping, leading to waterlogged soil and suffocation of roots. Proper drainage is essential to maintain healthy root systems. Using well-draining potting mix and checking drainage regularly prevents waterlogging.

Question 4

A group of students harvests 5 kg of spinach, packs half in plastic bags and half in damp cloth. After two days, the spinach in a damp cloth is fresher.
i. Why did the spinach in a damp cloth stay fresh longer?
ii. What lesson does this give about packaging?

Accepted Answer

i. The spinach in a damp cloth stayed fresh longer because the cloth allowed air circulation and maintained moisture without trapping excess water. This prevented wilting and rotting. Plastic bags trap moisture and reduce air circulation, causing faster spoilage.
ii. The lesson is that packaging should allow air circulation and maintain appropriate moisture levels to keep produce fresh. Using breathable materials like damp cloth is better for leafy vegetables than sealing them in plastic bags. — Leafy vegetables need moisture to stay fresh but also require air to prevent fungal growth and rotting. Damp cloth provides moisture and breathability, while plastic bags trap moisture and reduce oxygen, accelerating spoilage.

Question 5

Your school has received a donation of 15 (6 inch) pots for rooftop gardening as well as spinach, tomatoes and marigold seeds.
i. Which plants will you select?
ii. Justify your choice based on agro-climatic conditions, usefulness (food/decoration), life cycle and water requirement.

Accepted Answer

i. Selection: Spinach and marigold plants can be selected.
ii. Justification:
- Agro-climatic conditions: Spinach grows well in cooler weather and requires moderate water; marigold is hardy and grows well in various conditions.
- Usefulness: Spinach is edible and nutritious; marigold is decorative and can also repel pests.
- Life cycle: Both have relatively short life cycles suitable for school gardening.
- Water requirement: Both require moderate watering, manageable in rooftop conditions.
Tomatoes require larger pots and more care, so may be less suitable for limited space and pot size. — Spinach and marigold are suitable for small pots and rooftop conditions. Marigold adds aesthetic value and pest control benefits. Tomatoes need bigger pots and more space, so may not be ideal for 6-inch pots. Considering local climate and ease of maintenance, spinach and marigold are better choices.

Question 6

A family wants to try rooftop gardening, but is worried about the cost.
i. Suggest two recycled materials they can use as containers.
ii. How does recycling support the environment?

Accepted Answer

i. Two recycled materials for containers:
- Used plastic bottles or containers
- Old wooden crates or boxes

ii. Recycling supports the environment by reducing waste sent to landfills, conserving natural resources, saving energy, and reducing pollution. Using recycled materials for gardening containers also reduces the need to buy new pots, lowering costs and environmental impact. — Reusing materials like plastic bottles or wooden crates prevents them from becoming waste and reduces demand for new plastic or clay pots. This helps conserve resources and reduces pollution associated with manufacturing new products.

Question 7

Of the tasks that you did, which did you enjoy the most? Which did you enjoy the least? Give examples of what went well and what did not go well. What would you do differently next time?

Accepted Answer

This is a reflective question and answers will vary. A good answer includes:
- Identification of the most and least enjoyable tasks.
- Examples of successes and challenges faced.
- Suggestions for improvements or changes in approach for future attempts.

For example, a student might say they enjoyed planting seeds the most because it was exciting to see growth, but disliked packaging because it was difficult to keep produce fresh. They might plan to try different packaging methods next time. — Reflecting on experiences helps improve skills and understanding. Identifying what worked and what did not helps in planning better for future gardening activities.

Question 8

Give examples of how you can apply your learning in a real-life situation.
