How and when to plant calla tubers in the ground


Partners

Zantedeschia or calla - This is a very popular flower that can grow not only in flowerpots, but also in the garden. Therefore, this plant is in demand among most gardeners. Growing calla lilies at home is easy. The main requirement is the correct storage of tubers, preparation of the soil for planting, as well as flower care. As a result, your garden will be decorated with an exotic and aesthetically beautiful plant.

Selection of tubers for planting

Calla bulbs usually appear in online stores in early February with the opening of the spring flower season. To grow a beautiful and healthy plant, you should carefully check the purchased planting material. Otherwise, you can just waste money without getting a beautiful flower in your home or garden.

The quality of calla bulbs is determined by criteria such as:

  • smooth surface;
  • large size;
  • juiciness of tubers;
  • the presence of a steam on each bulb;
  • absence of damage, rottenness and other defects.

It is optimal to purchase those corms that were grown in your region. This will prevent problems with the plant's climate adaptation. You should not buy calla lilies that have a sluggish, wrinkled appearance and an uneven surface. Beautiful flowers almost never grow from such tubers. In the best case scenario, you will end up with abundant greenery without the arrowheads that are the basis of the zantedeschia's appeal.

Bulb size matters a lot

When choosing calla tubers, you should pay attention to their size. Large corms retain more nutrients. Thanks to this, a greater number of stumps will sprout from the base, which will bring the best “offspring” in the form of bright and lush flowers.

Also, the quality and aesthetics of the flower stalks depends on the size. For example, tubers of 18-20 centimeters grow much better than those whose size does not exceed 10-12 cm. They have large voluminous bushes that are resistant to bad weather and winds. But with rare exceptions, such sizes of corms are difficult to find in online stores or their price is much higher than average.

Preparing tubers for planting in the ground

It is optimal to store purchased zantedeschia bulbs in the vegetable compartment of the refrigerator or in rooms with temperatures from +5 to +15 C. Before planting in the ground, the tubers should be kept dry.

The first stage of planting is germination. In this case, the bulbs are placed in wide containers with prepared soil. This is best done in early March. It is imperative to lay drainage on the bottom, which will remove excess moisture. In this case, watering the tubers should be abundant, but not excessive.

The surface of the bulbs should be carefully checked before planting. If purulent areas or other injuries appear on it, they should be removed with a sharp knife. The cut is made to the healthy tissue. Cut off places must be treated with brilliant green.

The purchased tubers should be placed in a container with a fungicidal solution. This will be a prophylaxis against various infections, which in the future will have a good effect on the growth and flowering of calla lilies. Before planting, the plant needs to be dried a little.

The soil for planting zantedeschia should have a low acid reaction. Ideally, use a mixture such as:

  • garden land;
  • compost or humus;
  • clay or washed sand;
  • peat.

The pits for planting calla lilies vary in depth from 5 to 10 cm. This depends on the size of the tuber. The layer with which the bulb is sprinkled should not exceed 2-3 cm. A deep planting of the plant can lead to rotting of the stumps.

Tubers are stacked with bulges upward. They are the place from where the buds germinate. Incorrect planting almost always leads to the death of the plant.

In open ground, zantedeschia can be planted in late spring, when there will be no frost anymore. Subzero temperatures are capable of destroying the stubble and calla root system. The optimal period for planting is the second half of May until the end of the first ten days of June.

Leaving after disembarkation

For effective flowering, the flower needs a state of rest, during which weeding from weeds and abundant watering is excluded. Calla needs to be systematically revitalized with fertilizers with a moderate dose of nitrogen and potassium. This will effectively affect the greenery and flower stalks of the plant.

Zantedeschia is a moisture-loving flower. It must be watered regularly with water. But don't overdo it. Otherwise, the tubers with the rhizome will begin to rot, and the flower will simply die. Calla lilies should be removed from open ground before the first frost.


Dahlias are planted in pre-prepared areas, after placing stakes and digging holes around them. The landing site must be protected from the wind with fences, buildings or trees. Groundwater on it should not rise above 60-70 cm from the soil surface, otherwise the flower beds and flower beds must be raised by deepening the paths and grooves of the neighboring site.

The soil on which dahlias grow must be moisture-consuming and at the same time permeable. Fresh or rotted manure, peat, turf soil, compost of various contents, leaf humus, straw cutting and other organic materials that are easily decomposed in the soil are added to the ground.

To increase the permeability of clay soil, coarse sand, ash, gravel, washed and sieved fine coal slag are introduced. Clay, peat or vermiculite are added to sandy soils. In the fall, the site is plowed deeply and dug up to a depth of 30-35 cm. In the spring it is re-dug up and thoroughly loosened 2-3 weeks before planting.


In late February - early March, before planting in the ground, calla tubers are planted for germination. If the tubers are slightly withered, before planting, keep them for 2-3 days in a damp cloth until they become elastic again and the buds are clearly visible on the surface of the tubers.

Examine the tubers carefully.

If you notice damage to them or signs of dry rot, which often appears with improper storage, peel the tuber with a sharp knife to healthy tissue.

Lubricate the wound surface with brilliant green and let it dry.

To prevent fungal infections, treat calla tubers with any fungicide intended for dressing tubers and bulbs before planting. Preparations are well suited for this purpose. Fundazol and Vitarosthat have a systemic effect. They not only destroy fungi on the surface of the tuber, but are also absorbed by the plant, providing it with long-term protection. Dry a little before planting the tubers.

Fill a small pot with a nutritious earthy mixture about 2/3 full. The mixture should have a slightly acidic reaction. The composition of the soil for planting calla lilies: peat, humus or compost, leaf or garden soil, washed sand (2: 1: 1: 0.5). Compact the potting soil and place the tuber on top.

Cover the tuber with the prepared potting soil. The planting depth of calla tubers is 1.5–2 cm from the tuber top to the soil surface.

Water carefully, being careful not to erode the soil. Place the pot in a bright spot. Calla develops well at daytime temperatures of about +15. +20 ° C. It doesn't matter if at night the temperature of the calla lily drops to +13. + 15 ° С, the difference between night and day temperatures is beneficial for the plant.

Calla roots grow in all directions. So that they do not come out on the surface of the soil, as soon as the sprouts reach a height of 5-7 cm, add more soil to the pot in a layer of 2-3 cm. Keep the soil in a moderately moist state. Tubers do not tolerate excessive watering and stagnant water, so drain the water from the sump immediately after watering. Feed with a solution of complete mineral fertilizer for seedlings once every 2 weeks. A good result is brought by top dressing with liquid gummed fertilizer.

When the soil in the garden warms up to + 15 ° C and the threat of frost has passed, calla lilies can be planted in open ground. Calla does not like direct sunlight, so choose a place for her that is illuminated by the sun until noon. Prepare a 30x30 cm hole for planting, add half a bucket of humus and peat to it and mix well.

Remove the plant carefully from the pot. Despite the fact that the roots of calla lilies are powerful, they are very fragile and cannot be restored if damaged. Place an earthen ball in the hole.

Gently cover the area around the roots with soil. When planting, it can be deepened again by 1.5–2 cm, so as not to accidentally damage the surface roots when leaving.

Water, wait until the water is completely absorbed into the soil. After watering, mulch the plantings with peat to prevent soil crust formation.

Growing rules

When growing calla, you should follow these rules:

A bud that has blossomed in a shady place

As mentioned earlier, calla lilies prefer to grow in shady areas. Although they also react normally to sunlight. Such plants will feel great under the crowns of trees, as well as in places with a northwest or west location.

In areas with a lot of sun, calla lilies may not bloom in these areas. It is not uncommon for this culture to simply grow greens instead. Therefore, you should not repeat the mistakes of inexperienced summer residents who choose sunny places for calla lilies to grow.

The soil such flowers love nutritious, sour and necessarily loose.

Under natural conditions, zantedeschia grow near water bodies. This means that they are very fond of moisture. Although, when growing and caring, you should beware of stagnant water. It is for this reason that loose soil is recommended for growing calla lilies. If this condition cannot be met, then a drainage layer should be made.

After the calla tubers are purchased, you should carefully examine them again at home. Planting material should be healthy and even. Rotten places are cut out, and the tubers are soaked in a special fungicidal solution. After that, the cut is dried and sprinkled with crushed coal.

In order to get a lush flowering of calla, large tubers should be planted. As for the small ones, they must be planted in the ground so that they can gain strength and grow well.

Correctly planted calla lilies

Calla lilies need to be planted close to the soil surface. Some gardeners simply deepen them and sprinkle them with a small layer of soil (2 to 3 cm). It is very important not to confuse during planting, where is the bottom of the tuber, and where is its top. It should be remembered that the rosette should always be at the top, and the rudiments of the root system at the bottom.

The interval that should be observed during planting should be on average from 30 to 40 cm. The soil must be moistened. Do not water the soil immediately after planting. They begin to moisturize little by little and gradually. In this case, it is necessary to ensure that the earth does not dry out.

By following these rules, you can easily grow calla lilies in your backyard.


Preparation for disembarkation, selection of planting material

Planting in the garden is carried out only in early spring, in late April - early May. In the fall, rhizomes are not buried, since street feces do not withstand wintering in the middle zone. For planting, varietal tubers or seedlings are purchased in pots with a nutrient mixture. In order for garden flowers to grow healthy and beautiful, when choosing planting material, pay attention to the following points:

  • high-quality tubers are large in size
  • varietal bulbs should be dense, without signs of lethargy and wrinkles
  • the larger the rhizome, the faster the garden flower will bloom, perhaps this will happen in the first summer
  • planting material purchased in February is wrapped in a napkin, stored on the bottom shelf of the refrigerator
  • before planting, the tubers must be treated in a weak solution of potassium permanganate, lubricating the damaged areas with brilliant green to prevent decay.

It's important to know. Callas are propagated not only by rhizomes or purchased bushes. You can also buy seeds at a flower shop, but the process of growing them is quite long and laborious.

You can plant pre-purchased tubers in small diameter pots in March or early April.

  1. The soil is pre-calcined, and the containers are disinfected.
  2. The bulbs are buried 2-3 cm into the soil.
  3. Water the ground once a week, it can be a little more often if the houses are very warm.
  4. Since April, they are taken out to the balcony to ventilate so that the roots awaken from the dormant period.
  5. They are transplanted into the garden in May along with a lump of earth, trying not to damage the rhizome.


Methods for storing plants after digging up at home

There are several ways to store calla tubers until spring. An important point - before laying for the winter, all roots are cut off, otherwise the flower can grow.

Content in the basement

The tubers are placed in the basement. Successful storage depends on the correct temperature regime maintained, it ranges from +5 C to +10 C degrees. In no case should the temperature increase, this will lead to a premature, early onset of germination of the bulbs.

High humidity is detrimental to the planting material, so storage should be "dry". The basement itself must be ventilated, with a constant supply of fresh air. Otherwise, the bulbs will simply spray.

Accommodation for the winter on the loggia

This storage method is suitable for gardeners who grow calla lilies in a pot culture. In the fall, watering is gradually reduced, and after the first frosts and the death of the leaves, the pots are transferred to a glazed balcony or loggia. Calla lilies stay there until spring. It is important to control the temperature regime - in severe frosts, it is advisable to additionally cover the pots. And vice versa - it is desirable that there is no heating on the balcony, otherwise the calla lilies will grow.


Caring for garden calla lilies

  • Calla lilies should be watered rarely, only during drought.
  • They are practically not susceptible to diseases and pests. The exception is the whitefly, but to get rid of it, it is enough to treat the plants with an insecticidal preparation, for example, Commander.
  • It is better to prune faded flower stalks so that new ones appear.
  • Top dressing should be carried out every 2-3 weeks with fertilizers for corms. During flowering, you can add 15-20 g of potash fertilizers for each plant.

It is better not to get carried away with nitrogenous fertilizers, as they promote the growth of greenery, but not the appearance of peduncles.

Autumn care

  • If calla lilies are planted in the open field, then in September the bushes should be carefully dug up and the roots washed.

  • Keep for a couple of weeks in a room with a temperature of at least 5 and not higher than 15 degrees. During this time, nutrients are transferred from the leaves to the tubers.
  • After drying, the tubers must be separated from the shoots, but not cut to the very base.
  • Treat the cut sites with activated carbon.

  • Store at a temperature not exceeding 12 degrees, otherwise they will lose moisture. For additional protection against drying out, the tubers can be wrapped in paper or newspaper. But at the same time, you should periodically ventilate
  • If the roots have sprouted with improper storage, then they can be planted in a pot, and transplanted into open ground in the spring.


How to plant a calla tuber in a pot correctly

In the photo you see a planted calla bulb, which is not covered with earth from above. The soil was cleared in order to take the photo. In fact, the tubers must be completely covered with soil. But more on that later, because first you need to prepare for planting calla lilies in a pot for germination.

Pot and soil selection

As a pot for sprouting tuberous calla, you can take a bucket of mayonnaise, disposable pots or glasses. Their volume depends on the size of the tubers. Low capacities should not be. Approximately 10-15 cm tall. And choose the width so that after planting from the tuber to the edge of the pot it is 3-4 cm. Calla roots do not grow downwards, but from above (in the same place as the processes) and to the side, so the container should be larger than the diameter of the bulb.

Loose and neutral acidity should be the soil for the germination of calla bulbs. It is best to buy potting mix for bulbs or other garden flowers from the store. It is acceptable if the soil is slightly acidic (for example, for Saintpaulia).

Savvy gardeners can germinate calla lilies in their own prepared soil. To do this, garden turf soil is mixed with peat, sand and compost. There should be 2 parts of the land from the garden, and 1 part of the rest. But such a soil mixture will have to be disinfected. Find out the options for disinfecting the ground at home at the link.

How to plant and care for

Immediately before planting on the bottom, fill the drainage, and fill the pot 2/3 full with soil. The ground must be moist.

And now for some very important information! It is necessary to plant the calla tubers in the soil in the pot with the tubercles up. Shoots will emerge from these tubercles, and roots will form around them. You can see this in the photo above.

Place the onion on top of the soil and cover it all over with earth. The soil layer above the tuber should be 2-3 cm.

Pour with settled water at room temperature. It is better to pour it along the edge of the pot so as not to pour the onion. While the tubers are without roots, they should not be wet, but slightly damp.

Press down gently and add some more soil on top. This will prevent dry crust formation.

10-14 days before planting in open ground, begin to take out the germinated calla lilies for a short time to the balcony or area. They need to adapt to the open air, that is, harden themselves. How to properly plant on a flowerbed in the garden, read Here .

Video of planting calla tubers in pots for germination

In a video clip from the YouTube channel, you can see how to properly prepare and plant calla bulbs for germination. An experienced florist shows how to soak tubers in Fitosporin, remove old roots, mold and plant them in a pot correctly.

We hope that the step-by-step instructions have helped you understand when to get calla lilies after wintering and how to plant them for germination in a pot. Do not forget to pickle the tubers before planting.
