Over the Fence
My indoor garden started with a Royal Flush: During a poker game with friends, I was halving an avocado for guacamole when I realized, to my complete shock, that I had a good hand. Instead of pausing the game to throw the pit in the trash, I poked a hole in the soil of the nearest houseplant, dropped in the pit and forgot about it. I was reminded a month later when the fast-growing avocado plant took over the pot. You, too, can grow an indoor garden with kitchen scraps usually thrown onto the compost heap.

Garlic:
1. Plant a few garlic cloves with pointed tip facing up in a pot with loamy organic soil.

2. Place the pot on a sunny windowsill and water regularly like a houseplant.

3. Green garlicky shoots emerge in a week or so. Harvest with a scissors to using in cooking or as a tasty garnish for soups, salads and baked potatoes.

Green Onions:
1. Use green onions with healthy, white roots attached to the bulb. Snip off green tops for cooking with a scissors. Leave a little green top on the onion bulb.

2. Plant the entire onion while leaving the short top above ground in a small pot filled with a loamy, organic potting soil. Make sure your container has drainage holes. Put in a sunny windowsill and water once a week or when soil feels dry to the touch.

3. Harvest new green shoots with scissors to use for cooking or as a tasty garnish. Continue to leave the onion in the soil. With each new growth the onion will taste more potent. After each harvest of onion tops, dress the topsoil with organic compost. Enjoy green onion tops in stir-fries, omelets, and in sandwiches all winter long

Pineapple:
1. Indoor pineapple plants rarely produce flowers and fruit, but their striking foliage adds a touch of exotic to any houseplant collection. All you need to grow one is the green top you cut off when you eat the pineapple. For best results, use a pineapple that has fresh center leaves at the crown. Lob off the top, right where the crown meets the fruit. Peel off the bottom leaves and clean off the leftover fruit. Let the top rest a day before planting.

2. Fill a shallow pot with rich, loamy organic soil mixed with a few tablespoons of well-rinsed coffee grounds. Pineapple grows best in an acidic soil. Plant the pineapple top so the soil is even with the bottom of the crown.

3. Water well and mist the leaves and crown with a diluted, organic liquid fertilizer. As a member of the Bromeliaceae family, which also includes air plants, pineapple plants take much of their nourishment not from the soil but from nutrients in the moist air.

Avocado:
1. For best results use only a ripe avocado. Carefully halve the fruit and rinse the pit. Pat dry and let sit overnight in a warm, dry spot. The next day, peel off any of the parchment-like skin from the pit.

2. Place the pit with the base (the wider end) toward the bottom in a 7-inch pot full of loamy, rich organic soil. Make sure the tip is above the soil, exposed to light for proper germination. Water thoroughly.

3. If your apartment is dry, place a clear plastic cup over the exposed seed tip to serve as a mini-greenhouse. Though the plant does not need direct light to germinate, placing the pot on a sunny windowsill will speed growth.

4. Continue to water every week and make sure the soil doesn't dry out completely. The pit may take over a month to germinate so be patient.

5. When the sprout emerges and grows to about 4 inches, add another layer of organic soil to cover the pit completely. This not only protects the seed, but also any roots that may poke through the soil in search of nourishment.

6. Once the plant starts growing, it may remind you of the story "Jack and the Beanstalk." You can watch the plant grow tall for a year (supported with a wooden rod) and let it branch on its own, or make a decision to prune it and force it to branch, making a sturdier plant. If you choose to prune, it's best to trim with a diagonal cut 2 inches from the top. Be careful as you prune not to cut the main stem more than 1/3 of its height.

7. Continue to add organic compost to fertilize the soil with each pruning and water as you would a houseplant. Only repot the fast-growing plant when it is 6 times taller than the diameter of the pot.

8. Though avocado plants do not bear fruit if grown indoors, you can plant multiple avocado pits at various times in the same pot for a more interesting arrangement.
