First, the basic calla lily care
1. Place calla lily in a place with 4-6 hours of light every day. Calla lily likes bright, so choose the sunny place near the window or glass door. However, please avoid direct sunlight, especially at noon. Direct sunlight will burn leaves and flowers, causing them to turn yellow.
If the place where you put the plants is too dark, your calla lily may become smaller and the flower stems may not be so strong.
2. Keep the soil moist during the growing season. From spring to autumn, put your finger into the soil of the plant every few days to see how wet it is. If it is dry to about (5. 1- 10.2 cm), please water the calla lily until the soil is completely wet. Generally speaking, your calla lily works best if you water it often. If you let it dry too much, it may start to turn yellow and droop, and the flowers will not look so bright.
However, don't saturate plants-this will lead to root rot.
3. From spring to autumn, set the thermostat to (18–24 C). Calla lily actually performs very well at normal room temperature, which is part of their attraction as indoor plants. However, please try to keep the temperature quite consistent-large fluctuations throughout the day will affect the flowering degree of plants.
Keep your factory away from heating and air conditioning vents, because the temperature fluctuates more in these places.
If you live in a dry climate, please put a humidity tray under the plants. Calla lily likes an environment with a relative humidity of about 40%. If your air is drier than this, please fill the shallow tray with smooth pebbles, and then add enough water to the tray to cover the bottom but the pebbles will not be completely submerged. Place calla lilies on pebbles-when water evaporates from the tray, it will moisten the air and help plants thrive.
Add more water to the tray every few days or when the tray is dry.
If you don't want to make a humidity tray, you can also spray calla lilies with water mist every few days.
Alternatively, you can run a cold mist humidifier to prevent the air in your home from drying out.
5. Apply liquid fertilizer to calla lily once every two weeks. Calla lily needs a lot of nutrients in the soil, so they'd better feed it regularly. Choose 5- 10-5 or 5-10/0 liquid fertilizer, which contains 5% nitrogen, 0/0% phosphorus and 5% potassium or 0/0% kloc. It should be safe to use these every other week during the growing season. Explain how to fertilize according to the label-usually you will mix them in water and then pour the mixture on the soil.
Once your flowers wither, stop fertilizing the plants.
6. Cut off the stems after the flowers wither. Eventually, the flowers on the calla lily will start to wither and turn brown. When this happens, please use scissors to cut off the flower stems near the base of the plant.
This is mainly for beauty, so there will be no ugly dead flowers or withered stems in your plants.
7. Replant every two years or when your plants seem to have fixed roots. Eventually, your calla lily will grow out of the flowerpot. Choose a new pot slightly bigger than the ball. Gently remove the calla lily from the old pot, and then carefully put it into the new pot. Within a few days after replanting, fill the flowerpot with well-drained potted soil and add water to the plants.
Be careful not to damage the roots when transferring plants.
8. Put calla lilies out of the reach of children and pets. Every part of calla lily is poisonous, from rhizome and root to leaves and flowers. If you have children or pets, they may try to eat this plant-or even just play with it-and put it in high and remote places.
If children or animals put calla lilies in their mouths, you may notice that your lips, tongue or throat are drooling and swollen. They may also have stomachache and diarrhea.
If you suspect calla lily poisoning, please call the poison control center or seek emergency care.
Second, pests and diseases.
1. If the leaves have dark tips, please reduce watering or fertilization. As the results look the same, it is difficult to determine which one caused the problem. However, if you have recently started to fertilize plants more frequently (or you have switched to new fertilizers), this may be the culprit. The same is true if you have changed your watering plan recently.
If you are still not sure, please let the plants have a rest from fertilization and watering. Wait until the soil is dry to about (10 cm), then water it, and stop fertilization within 3-4 weeks.
2. If the leaves look gray, please check whether there are spider mites. These tiny mites will feed on calla lilies and gradually turn their leaves yellow and gray. Fortunately, getting rid of these mites is very easy-just take the plants outdoors and spray them with water.
If the mite appears again, you may need to repeat it several times.
3. If aphids are found, please spray the plants with neem oil. Aphids, also known as plant lice, are another pest that may feed on calla lily. Aphids are small insects with soft bodies, and you usually see them in groups. Neem oil is a natural insect repellent for aphids, but you can also spray plants with insecticidal soap if you like.
4. If stem rot or ring mosaic virus is found, please destroy the plant. These diseases can spread to other plants, and once formed, plants cannot be cured. Put on gloves, pull the plant out of the pot, and then throw the whole plant into the trash can. For the sake of safety, it is best not to reuse the soil where plants are located.
If your plant has stem rot, the stem will start to soften and your plant will start to tilt.
If it has ring mosaic virus, you will notice yellow discoloration on leaves and stems, which looks like stripes or spots.
Third, wintering
1, stop watering and feeding plants every winter. This will give your calla lily a chance to rest for 2-3 months. This is an important process if you want to preserve calla lilies for more than one season. Even if you live in a place where the climate is not too cold, give your plants a winter vacation. If you don't let your plant spend the winter, it won't bloom next year and it won't be so healthy as a whole.
Although you can stop fertilizing the plants immediately after the flowers wither, it is better to water the plants gradually instead of suddenly stopping.
Once the plants turn yellow, cut them into the soil. Cold temperature combined with lack of water and food will cause plants to wither. Don't panic-this is actually what you want. Once the leaves turn yellow or brown and start to droop, please trim them into the soil with sharp scissors.
Your plant will grow healthy new leaves in spring.
3. Put the jar in a cool and dark place. After cutting the leaves back, just leave the roots in the pot. Just put the whole container somewhere around (4-16 c), such as a cellar.
Some gardening experts suggest adding a little water to the soil every once in a while, so that the tubers will not dry completely.
In April, 65438+10-March, fresh soil was replanted. If you replant roots (sometimes called tubers) in early spring every year, your calla lily will be the healthiest. Pull the roots out of the soil-they may look like a big clump, but it is usually divided into smaller parts, each with its own bud. Cut these roots with sharp scissors. Then, replant the largest rhizomes in fresh potted soil, because they will produce the strongest plants.
Buds, also known as eyes, look like small tips on rhizomes.
Even if you plan to plant calla lily indoors, it's best to start planting about one month before the last frost.
If you don't separate the roots, your calla lily may be too big to put its flowerpot. As it grows, it may be unhealthy and difficult to stand upright.
Fourth, potted roots
1. Select a basin with a diameter of (13- 15cm) for a single bulb. The flowerpot of this size is beautiful, and there is also a calla lily growing inside. In addition, it will provide enough space for the root.
If you want to plant a variety of bulbs in a container, please use a flowerpot with a diameter of (20 cm) or more.
Make sure your container has drainage holes, otherwise the roots of plants will be soaked and rotted.
Whether you plant new calla lily bulbs or replanted bulbs separated after wintering, use flowerpots of the same size.
2. Fill the container with well-drained potted soil. You can use many different potting soil combinations, but generally speaking, it is best to start with soil with sphagnum. These types of soil can be kept moist without too much water to avoid the root rot of calla lily.
Try a flowerpot made of equal amounts of sphagnum and perlite.
Test the soil pH value to ensure that it is slightly acidic (pH value is between 5.5 and 6.5) and adjust it as needed.
3. Put the rhizome of calla lily into a hole 2.5-5. 1 cm deep. Dig a shallow hole with your fingers, and then put the rhizome in this hole with the bud facing up. Then, cover the soil, so that the top of the rhizome is hardly exposed to the soil surface.
Plant the biggest and strongest roots-this will grow stronger and bigger plants.
Usually, one side of a tuber is round and the other side has sharp buds.
4. Water the plants after potted. Fresh potted plants usually need a lot of water, and calla lily is no exception. Give it a lot of water, but not so much that it drowns the pot.
Ensure that the potting mixture remains moist throughout the growth process.
5. Place the pan at the temperature of (21–24 C). Warm temperatures will signal to plants that winter is over. After about 2 weeks, you will see the first bud begin to appear.
If there is not much sunshine in the place you choose, please move the flowerpot to a sunny place after the bud begins to grow.
According to the type of plants you have and the general growth conditions, your calla lily should begin to bloom about 13- 16 weeks after you replant the roots.
