Want to grow an enormous pumpkin for Halloween? Now's the time to get started. Today you'll learn how to grow a giant pumpkin that will make a huge ?Jack-O- Lantern? that'll attract attention. First, dig a 2-foot round hole and fill it with compost. Then cover it with a layer of topsoil. Plant three or four large pumpkin seeds an inch deep. When they sprout, save only the healthiest one. Keep it watered, and apply high-phosphorous fertilizer. When three fruits appear, pick off the female blooms (the flowers with a bulge behind them). When pumpkins reach grapefruit size, save only the one that's the best and lose the rest. Then watch it grow, and grow, and grow. Be sure to harvest it before the first frost. Store it indoors in a warm place for about a week, then a nice cool place until it's time to carve out its face. Get started now and you'll scare folks with pride, with shining face and a candle inside. And that's the On The House tip for today.
