In any ornamental or mixed greenhouse staging is important as here plants are placed to waist height and watering and care are made easier. Staging is also necessary for propagating and growing on young plants. The staging can be removed for summer crops if necessary.Read More »
Another useful help for your tender plants or for extending the growing season are the cloches. There are a wide range of cloche designs and materials available, so you can choose the right cloche that suits the types of plant you are growing. They are mainly used in the vegetable garden but they can also be used for protecting ornamental plants and seedlings that need a little extra warmth during winter or early in the season.Read More »
Cold frames are useful because they offer extra space near your greenhouse and are extremely useful especially in spring to harden off plants raised in the greenhouse but also during the other seasons to grow a wide range of crops. In the colder months they are used to protect winter flowers, to overwinter the seeds of hardy annuals sown in autumn and to shelter vulnerable alpines from the worst of the wet weather.Read More »
In order to keep the greenhouse in good shape it requires a constant maintenance, inside and outside. Ann annual check in autumn will be enough to keep your greenhouse in good working order. For routine work on the outside of the greenhouse you should choose a dry, still day. Before starting the work, gather together all necessary materials that you need for cleaning, repairing and repainting.Read More »
The best method of watering a mixed collection of plants in a small greenhouse is the traditional watering can. It might be time-consuming using one but it allows you to monitor the flow and ensures that all the plants are watered according to their individual needs. A useful addition to a greenhouse is an automatic watering system, especially in the summer or when the greenhouse is left unattended on a regular basis, since some pot plants may need to be watered several times a day in very hot weather.Read More »
Humidity is the measure of the quantity of water vapor in the air. In the greenhouse humidity is important because the air humidity affects the rate at which plants transpire. By transpiration plants are drawing water along with nutrients from roots to leaves where the water then evaporates from leaf pores into the air. As water evaporates the plants are cooled down.Read More »
Lighting in the greenhouse is essential, especially for some plants that require many hours of light. If you already have an electric power supply in your greenhouse then you can install lighting units at any time and they are not expensive. The running costs are low also. The light installed in the greenhouse produce a little extra heat for the plants. Ordinary fluorescent lamps provide enough illumination to work by comfortably.Read More »
Shading the greenhouse will help to control the temperature levels if the ventilation system is insufficient. It also helps to protect vulnerable plants from too much direct sunlight. This will reduce the risk of leaf scorch and will prevent flower colors from fading in strong sunlight. Shadings applied primarily to control the temperature levels should be placed on the outside of the greenhouse as internal shadings are unlikely to reduce the temperatures significantly.
The amount of shade that is required in a greenhouse is not always the same, it depends on the season and the plants that are grown in the greenhouse. In the months of strongest sunlight, shading that reduces the light by 40-50 per cent is suitable for a typical mixed greenhouse. Ferns prefer around 75 per cent filtering of light, while cacti and succulents require very little or no shading at all.Read More »
In a greenhouse a good ventilation is essential, even over the winter, to avoid a built-up of stuffy or damp, stale air and to control temperature levels. The area covered by ventilations should be equal to at least one sixth of the floor area. There are few types of ventilation methods that you could use in your greenhouse, depending on the type of greenhouse that you have.
Few models of greenhouse are supplied with enough ventilations as standard, so you might need to order some additional air vents, hinged and louver windows or extractor fans when buying a new greenhouse. This type of additional ventilations are difficult to be add after you buy the greenhouse so is better to order them before you buy the greenhouse. This extra ventilation is mostly needed if you are going to use paraffin or bottled gas heating systems.Read More »
In addition to heating, your greenhouse may benefit from a proper insulation and the heating cost will be reduced considerably. The higher the temperature to be maintained and the colder the region, the more cost-effective insulation is likely to be. Choose your insulating materials carefully because some of them may reduce the amount of light reaching the plants. Here are some of the most used types of greenhouse insulations: double-glazing, flexible plastic, thermal screens and base cladding.Read More »
