Plant transplant - when to do it

Plant transplant - when to do it

A transplant is one of the activities that every amateur florist needs to master. It consists in moving the plant from one pot to another.

But it is not necessary to replant the plants annually. The need arises for several reasons, let's look at the main ones.

When is a transplant necessary?

1. After purchasing from a flower shop:

  • - 2-3 weeks after purchase, when the plant has adapted to the conditions of the apartment;
  • - mini-orchids (phalaenopsis) must be transplanted immediately into fresh orchid substrate, because the soil in which they are located is too moist and dense to grow.

It is necessary to transplant the plant into a new pot, 10-20% larger than the previous one.

2. The plant is cramped in an old pot:

  • - the earthen lump is completely filled with roots, they can be seen in the drainage holes and on the surface of the lump;
  • - water is poorly absorbed during watering, stagnates on the surface;
  • - the plant has stopped growing, new leaves are smaller and grow slowly.

It is necessary to transplant the plant into a new pot, 20-30% larger than the previous one.

3. The structure and composition of the soil deteriorated:

  • - the soil in the pot did not change for 3-4 years and a white bloom appeared on it;
  • - water is absorbed very slowly, there may be an unpleasant odor in the pot.

A complete replacement of the substrate is required.

If the roots have completely filled the earthen lump, the pot needs to be taken 10-20% larger than the previous one, if not, the same size.

4. The plant got sick:

  • - for 2-3 days the soil in the pot remains moist, and the development of the plant stops;
  • - in plants with leathery leaves - the lower ones turn yellow and fall off;
  • - in plants with a herbaceous structure - the leaf can lose elasticity and become lethargic;
  • - if you take the plant by the trunk and shake it to the sides, it will stagger freely.

A complete replacement of the substrate is required, replacing the pot with the same or smaller one.

With strong root pruning, the diseased plant requires less volume.

5. Transplanting young and fast-growing plants:

  • - annually;

6. Transplanting adult plants:

  • - every 2-4 years,
  • - large-sized plants in tubs are transplanted if the containers have lost their decorative effect, collapsed or become too cramped.

Time to transplant indoor plants

It is believed that plants can be transplanted throughout the year, if there is a need for it, namely plant disease. In this case, replacing the substrate and cleaning and treating the plant can save it. But the most optimal time for transplanting or planting is from early March to mid-May.

It is not recommended to replant plants after June that have a period of winter dormancy. New soil can stimulate the plant to grow at the wrong time.

After a dormant period, the plant can only be replanted at the beginning of the growing season, when they wake up. It is also not recommended to replant plants during flowering, especially if this is not necessary.

Earthy mixture for flowers

In nature, plant roots develop in a fairly large space. In indoor conditions, the root of the flowers must adapt to survive in the pot, and this is a very limited volume. Therefore, the soil must be selected correctly with the right amount of nutrients for the flower.

Indoor flowers relate in different ways to different types of earthen mixture. Some require acidic soil (asparagus, begonia), others - slightly acidic (rose, chrysanthemum), and some prefer to grow on rich alkali.

There are plants that thrive in lime-dominated soil. And vice versa. So, for example, on camellia, an excessive amount of lime has a very detrimental effect.

In the store you can find substrate for azaleas, for conifers, for Saintpaulias, soil for flowering plants and many others. In such substrates, most likely, a set of trace elements and acidity are selected that are most suitable for a particular group of plants.

How do you choose the right earthen mixture?

The potting mix should:

  • contain the right amount of nutrients,
  • properly remove excess water,
  • there must be good air passage to the root system;
  • the right acidity for the selected green pet;
  • safe from pests and various kinds of plant diseases.

Mixtures of purchased Universal soil for plants and garden soil with the addition of sand, perlite, vermiculite have proven themselves well.

Before use, some amateur gardeners advise to steam or warm up garden soil in an oven with a temperature of no higher than 125 ° C.

Some plants (including indoor plants) are planted in soil containing manure, humus (plants with rapid growth), leaves (plants with a well-developed root system), turf (flowers with fleshy and thick roots). For example, bananas grow well on a mixture of turf and leafy soil.

In addition, every amateur grower should have river sand, as well as bark and moss, if you want to give the earth lightness or looseness. Also, air roots are often covered with moss and bark or simply decorate the trunks of plants.
