All through the three days I was assigned simple jobs like watching over the plants in the main hall, watering the plants, carrying pots and furniture around, handling the sales of the Green Heritage booklets, and so on. And with Alexyz around each task was great fun. On the last day, there was the prize distribution ceremony. I was proud and happy to receive a special certificate for having assisted in the Green Heritage Festival. As the fair came to an end the organisers all felt that it was yet another successful event. I was happy to have been a part of it. But the fun was not yet over for we all had a barbecue dinner that evening that lasted well into the early hours of the morning. We slept only briefly for there remained the final task of returning the pot exhibits to their respective owners. This we commenced early next morning. I had enjoyed my work at the Green Heritage and my stay at Alexyz's house. I was indeed sad when it all ended. I rested the next day at Alexyz's house and on the 18th morning, left for home. Field Work Notes: Growing Cacti At Home Cacti are plants suited to the desert and we must keep this factor in mind always when growing ornamental cacti in our gardens, for it helps in the survival of the plant. For example, a cactus should never be watered over its body as it will start to rot. This is because it is covered with a waxy coating which prevents water loss through evaporation. When one waters the cactus over its body, the waxy coating is washed away and the plant begins to rot. The amount of water that you must supply to the cactus is very much dependent upon the season and upon the climate of the place. During the summer season one should water cacti every four days whereas in the rainy season once every fifteen days is quite enough. Cacti need a minimum of two and a half hours of sunlight per day. However they should not be kept all day in the sun because they may wrinkle in too much of bright sunlight. Unlike other plants cacti produce carbon dioxide during the day and oxygen during the night. Hence, they are ideal plants to be kept in bedrooms to freshen up the air at night. If the cactus plant is to thrive and prosper, the size of the pot in which it is grown has to be carefully monitored. The pot should always be a little smaller than the plant itself because it is only when the plant has to struggle to survive that it will thrive. If the pot is too spacious the struggle element is removed and the chances are that the cactus will die. Cacti are like human beings. When they suffer they will grow. Similarly if a cactus shows no signs of growth, stop the watering. It should be resumed only when the plant resumes growth. The substrata of a cactus pot is ideally composed of pieces of broken bricks at the bottom, charcoal above it, then coarse sand and pebbles above it. Leaf mould is the best manure.
