Key design points of the semi-hydroponic moisture pot, with a detailed explanation of flower planting techniques

In the process of growing flowers, too much water will cause root rot, and too little water will cause the plants to wither. Beginners especially find it hard to control watering properly. So today, the editor will talk about a new technique that satisfies the plant roots' need for both air and water, namely the semi-hydroponic moisture pot. Next, the editor will explain in detail the key design points of the semi-hydroponic moisture pot.

I. Key design points of the semi-hydroponic moisture pot

Before designing a semi-hydroponic moisture pot, you need to prepare two pots. The outer edge of the inner pot should be sized so it can rest on the outer pot. The outer pot must be taller than the inner pot, and the bottom of the inner pot must have multiple holes. Drill a small hole in the side of the outer pot 4cm below the bottom of the inner pot, for gas exchange and water level balancing. Put some water in the outer pot, fill the inner pot with soil, place it on top of the outer pot, and it is ready to use. There are many materials that can be used. For ease of understanding, a bucket and a plastic basin were used here as raw materials to make the water-air pot as shown in the pictures:

II. Advantages of the semi-hydroponic moisture pot

1. Structurally drought-resistant, yet it allows the plant roots to obtain water from the moisture layer and the water layer in the outer pot until the water in the outer pot dries up.

2. Structurally waterlogging-resistant, allowing the roots extending from the inner pot to pass through the moisture layer, providing sufficient oxygen and preventing the plant from drowning due to excessive water.

3. Fertilizer retention: even if watering causes leakage, fertility will not be lost but will be stored in the water in the outer pot.

4. Easy conversion from soil to water: it can be converted to hydroponic growing.

5. Easy soil fertility testing: simply take out the water in the outer pot and estimate the fertilizer concentration.

6. High cleanliness: soil will not spill out from the bottom during transport.

7. Less soil is used: the plant roots can obtain oxygen from the moisture layer and do not rely solely on soil.

8. The soil stays consistently moist: when many roots pass through the pot and touch the water surface, capillary action forms, so even without watering the plant will not become too dry.

9. Convenient root observation: take out the inner pot and you can observe the growth of the plant roots.

10. Micro-convection inside the pot forms a weak airflow, which is beneficial to the respiration of the plant roots.

11. Alleviates fertilizer burn to seedlings, avoiding or significantly improving the phenomenon of fertilizer burn damaging seedlings.

Key points of repotting techniques for potted flowers

[Common question] Key points of repotting techniques for potted flowers

[Expert answer]

Repotting is done because the flower's root system keeps growing, and the small pot can no longer meet the flower's growth needs, so a larger pot is needed. Moving the flower from the original pot into another pot is called repotting. Below, the First Agricultural Economics editor will show you the key points of repotting techniques for potted flowers:

● Preparations before repotting.

Stop watering 1-2 days before repotting, so the potting soil becomes a bit drier, making it easier for the potting soil to separate from the pot wall and facilitating the operation. To remove the dryness and alkalinity of a new pot, soak it in clean water for a full day and night before use.

In addition, some of the original old soil also needs to be removed, and overly dense old roots should be cut off, then the original flower pot can be used with new cultivation soil for potting.

● Repotting methods for small and medium potted flowers.

When repotting small and medium potted flowers, gently tap around the flower pot with your hand, turn the pot plant upside down or tip it to one side, then support the potting soil in the pot with one hand and lightly tap the bottom of the pot with the other. The potting soil and pot wall will separate automatically. After tipping out the plant together with the soil ball, plant it into the new pot.

If the soil is relatively compact and cannot separate automatically, hold the main stem of the plant cluster with your hand, lift the flower pot slightly off the ground, and at the same time lightly kick down on the rim of the pot with your foot, and the flower pot will come off automatically.

● Method for repotting large potted flowers.

When repotting large potted flowers, because the potting soil is too heavy to lift by hand, do not use tools to dig it out, so as to avoid damaging the roots. The correct method is to lay the flower pot on its side, then roll it back and forth on the ground a few times to loosen the potting soil from the pot wall, and then use the above method to take the root ball out of the pot.

[Editor's summary]

Generally, the repotting time for potted flowers is during the tree dormancy period, from late February to early March in early spring. At this time the flower's metabolism is slow, and repotting is beneficial to the flower's recovery. In this article, the First Agricultural Economics editor has introduced the key points of repotting techniques for potted flowers, and hopes it will be helpful to you.

Key technical points for potted flowers in winter

When autumn is about to end, potted plants need to be handled so they can overwinter without being affected by cold damage. In early winter, potted flowers accumulate nutrients and differentiate flower buds. At this critical moment, overwintering management of potted flowers is very important. Below is an introduction to the key technical points for potted flowers in winter.

Introduction to the key technical points for handling potted flowers in winter:

1. Cold protection for flowers is determined according to their growth habits and temperature requirements. In winter, flowers stop growing,

a. Those entering dormancy, such as Chinese rose and lotus, must all be placed in a space of at least 3 degrees,

b. Semi-dormant flowers, such as bougainvillea, gardenia, and camellia, need a guaranteed temperature of at least 5°C,

c. Plants that do not go dormant and continue growing, such as begonia and carnation, need a greenhouse space of 8-10 degrees or above for cultivation.

2. Fertilizing plants in winter cannot be ignored. If the potting soil is dry, water promptly after fertilizing. In addition, foliar topdressing can be combined with pesticide spraying to supplement flower nutrition. Commonly used topdressings include 0.5% urea, 1% superphosphate, and 0.3% potassium sulfate.

3. Potted flowers should also be sprayed with pesticides in winter. Although low temperatures relatively reduce pests and diseases, prevention is still indispensable. Focus on preventing and controlling leaf shot hole disease, aphids, red spiders, and leaf miners and other pests and diseases. Generally, 50% carbendazim 800-fold solution plus 40% dimethoate emulsifiable concentrate 1500-fold solution, or 50% thiophanate wettable powder 600-fold solution plus 40% isocarbophos 1000-fold solution and other agents can be selected for control.

4. Plants should also be pruned in winter. Pruning flower branches during the dormant period can promote more buds, flowering, and fruiting on the branches the following year; for perennial vine flowers, cut out overly dense branches, overlapping branches, and diseased and pest-infested branches; for shrubs grown for their ornamental branches and trunks, such as red osier dogwood, choose new shoots near the main branches for heavy short pruning to make them send out new branches.

5. Finally, there is the soil issue. Plant roots need to breathe, so the soil only needs to be loose, breathable, fertile, and well-draining.
