According to Balsis, the greatest time to change pots is in the spring since plants put forth new growth during that time. When it comes to pots, though, bigger does not always imply better. If you merely move up one pot size, your plant will produce new roots to cover the empty area. "You don't want to brag about your root pot," he explains. "If you look after these plants well, they should remain small for several years."
In general, if you double the depth of the soil and quadruple the width, then the volume of soil increases by eight times:.
Volume of Soil = Width x Depth x 0.5.
For example, if you double the width and depth of a 12-inch-diameter pot and use a mixture of equal parts sand and compost, the calculated volume would be 1 cubic foot (30.5 L).
The actual volume of the soil itself is much less than this because it's mixed with water; however, as long as you add an appropriate amount of fresh material every time you change the soil, the volume of the container doesn't matter much.
As far as the number of plants per square foot of surface area goes, there is no real limit except that you need enough space to grow them. However, if you want to maximize your harvest, then you should place them in groups of four to six, depending on the strain.
The size of the pot is determined by the size of the root ball. Pothos rarely has to be replanted and may live in a smaller container, which also helps keep the plant from getting too huge. Only transfer the pothos to a larger pot if the roots start to clog the drainage holes or the plant begins to lift from the soil. New plants should be placed in a pot at least as large as their current one so there are no transplant shock effects.
Pothos prefer high humidity conditions during dry spells. If you want to take cuttings from your pothos, select healthy green shoots about 3 inches tall. Cut the shoot just below a node (joint) where two branches meet. Take several cuts around the base of the shoot, then peel back the outer layers until you reach the white or pale colored tissue. Snip off any dead or diseased parts of the cutting and insert it into some fresh, moist soil. The cut end will form a new growing point and provide more leaves for your pothos.
Pothos are very easy to care for. They require regular water during drought conditions and some fertilization once a month with a high-nitrogen fertilizer such as 12-12-12. Pothos do not need much sunlight but would benefit from an hour or two of direct sun each day. In warmer climates, this could cause the plant to grow faster than expected; move it into a shaded area if it starts to cast its leaves early.
Larger pots require more water, which increases the likelihood of root rot. When we repot the plant to a larger pot, we must take care of the roots when untangling and repotting. We may not notice any growth if the roots are injured throughout the process. Let the original soil dry out a little before re-potting in fresh soil.
In various sized pots, the larger pot will produce more. The plant will utilize its 2-3 week stretch to establish roots and determine its maximum size.
Place a plant in a pot that is the same size as the one in which it is growing. When transplanting a plant that has outgrown its existing container, choose a pot that is 2-4 inches bigger in diameter. For plants that develop swiftly, choose a bigger size container. A pot that is 1-2 inches bigger works nicely for sluggish growth. Water vigorously until the soil is moist to the touch, then let dry out slightly before rewatering daily if needed.
The type of plant will also influence how much water it needs. If you own a house, look on the greenhouse or porch where plants like these are kept to find out what size pots they have been sold in. It's best not to use containers larger than what they were sold in, because plants won't have enough space to grow and won't be able to use their energy stores properly. Too many large containers also increases the risk of root damage from water and soil contamination.
Finally, consider the amount of space you have available for your garden. Some plants need more room to spread out than others do. Peas, beans, and cucumbers, for example, can all fit into 10-12 inch containers while tomatoes require at least 12-16 inches. Consider how much space you want to give each plant when choosing the size of your pot.
When repotting plants, always work with healthy shoots instead of the whole root ball.
Plants should be repotted every 12 to 18 months, depending on how quickly they grow. Some sluggish growers can live in the same pot for years, requiring just soil replenishment. Re-potting your houseplants in the spring, before the start of the growing season, is typically the optimum time. Fall is also a good time to re-pot plants that were grown during the summer; this will allow them time to recover from being outside in cold temperatures.
Houseplants need different amounts of water depending on their size and how much heat they get during the day. Small plants require more attention than large ones and deserve a spot in a window with some sunlight. Plants that get direct sunlight all day long don't need as much water as those in partial shade. If you forget to give your plant enough water, then it's going to suffer from dehydration which can cause the leaves to wither and drop off. You should water your plants at least once a week, depending on the temperature. If it's very hot out then you'll need to water sooner than if it's not so hot out then you can wait until later in the week.
If you want your plants to produce flowers, then you should change the mix about every other year. This will help promote new growth and ensure that the right nutrients are available to the plant. It's important not to overdo it with the fertilizers since this will burn your plants.
