Pots-sizes and kinds

Regular clay pots are as deep as they are wide at the top. There are also three-quarter pots, called azalea pots, and bulb “pans.” These are not really pans but simply pots which are about half as deep as they are wide. Pans are just right for rooting cuttings and forcing bulbs. The orchid pot has holes spaced all around the sides for extra drainage.

Some gardeners prefer plastic pots. They come in various shapes and sizes and can be time-savers for an experienced person who understands watering and the needs of plants. The plastic pots are lightweight, attractive, easier to clean than clay pots, and more retentive of moisture. Most commercial growers, nevertheless, still use clay pots for growing, reserving the plastics for shipping. They maintain that a clay pot is ideal because it is porous. Roots need to grow out and around the inside of the pot, and require water, nutrients, and air, which they receive more effectively in clay. Feel a clay pot filled with moistened soil and you will note that it is 10 to 15 degrees cooler than a plastic pot of soil. And that’s a healthy condition for roots.

If you have old pots, scrub them well before use. I add 6 tablespoonsful of Carco-X to the boiler of water in which I wash pots. This antiseptic, which contains some tar, removes soluble salts and algae, and is not hard on hands. Never store plastic pots outdoors, as sudden temperature changes often cause them to crack.

If you live in Arizona, New Mexico, Texas, or other areas where summer heat produces excessive evaporation, you may save work by using plastic pots. However, crusts or chemical concentrates (resulting from fertilizing) may form and necessitate frequent repotting or scraping away from top soil.
