Polytunnel

A polytunnel is a tunnel made of polyethylene, usually semi-circular, square or elongated in shape. The interior heats up because incoming solar radiation from the sun warms plants, soil, and other things inside the building faster than heat can escape the structure. Air warmed by the heat from hot interior surfaces is retained in the building by the roof and wall. Temperature, humidity and ventilation can be controlled by equipment fixed in the polytunnel.

The idea temperature in the polytunnel is between 23º and 25º. At higher temperatures the fungus will grow and attack the plants.

Apart from special equipment we can modify the temperature and the humidity inside the polytunnel using very simple techniques.

To lower the temperature we can:

- Paint the glasses in white to

- Open the doors

To raise the temperature we can:

- Put the blinds in the evening

- Place a reflecting blanket

- Use a propane burner

- Place hot-water pipes

- Place red lamps

If we are building a green house we can build the south face with brick as it will retain the heat inside them and the north side with stone to avoid loosing the temperature on that side.

If we need to lower the humidity inside the polytunnel we will open both ends of the tunnel to circulate the air.

Malus domestica - Apple tree

Latin plant name Malus domestica Common plant name Apple tree Plant type Deciduous fruit tree  Size (meters) <3-12 m Distinguishing -features The leaves are alternately arranged simple ovals, petiole with an acute tip, serrated margin and a slightly downy underside. Blossoms are produced in spring simultaneously with the budding of the leaves. The flowers are white with a pink tinge that gradually fades, five petaled. The fruit matures in autumn. The center of the fruit contains five carpels arranged in a five-point star, each carpel containing one to three seeds, called pips.

Euphorbia pulcherrima - Poinsettia

Latin plant name Euphorbia pulcherrima Common plant name Poinsettia Plant type Shrub flowering plant Size (meters) < 4 m Distinguishing features The poinsettia is a culturally and commercially important plant species of the diverse spurge family that is indigenous to Mexico and Central America. It is particularly well known for its red and green foliage and is widely used in Christmas floral displays. In areas outside its natural environment, it is commonly grown as an indoor plant where it prefers good morning sun, then shade in the hotter part of the day. However, it is widely grown and very popular in subtropical climates such as Australia.

Courgettes

Courgettes are also called zucchini. 

In a culinary context, the courgette is treated as a vegetable, which means it is usually cooked and presented as a savory dish or accompaniment. Botanically, however, the zucchini is an immature fruit, being the swollen ovary of the zucchini flower.

Courgette is one of the easiest fruits to cultivate in temperate climates. As such, it has a reputation among home gardeners for overwhelming production. One good way to control over-abundance is to harvest the flowers, which are an expensive delicacy in markets because of the difficulty in storing and transporting them. The male flower is borne on the end of a stalk and is longer lived.

While easy to grow, courgettes, like all squash, requires plentiful bees for pollination. In areas of pollinator decline or high pesticide use, such as mosquito-spray districts, gardeners often experience fruit abortion, where the fruit begins to grow, then dries or rots. This is due to an insufficient number of pollen grains delivered to the female flower. It can be corrected by hand pollination or by increasing the bee population.

The courgettes need a neutral high rich organic soil. They need warmth and shelter so in Ireland it is a good option to plant them inside the polytunnel.

Three sisters planting

The Three Sisters Garden is a wonderful example of relationships in the garden. From a scientific, agricultural perspective these relationships are between particular families of plants, legume family (beans, peas), the grass family (corn) and the gourd or curcubit family (squash, pumpkins and melons).

The "three sisters" are maize/corn (Zea mays), beans (Phaseolus vulgaris L.) and squash (Cucurbita spp.). According to historical records, the farmer dug a hole in the ground and placed one seed of each species into the hole. The maize grows first, providing a stalk for the beans, which reach upward for access to the sun. The squash plant grows low to the ground, shaded by the beans and corn, and keeping the weeds from affecting the other two plants.

Today, intercropping in general is recommended as an alternative system for small-scale farmers to improve their yield, and thus food production and income in limited spaces. Inter-cropping is also insurance: if one of the crops fail, the others might not, and the farmer is more likely to get at least one of the crops to produce in a given year, no matter how extreme the weather circumstances.

The microclimate produced by the three sisters combination favors the survival of the plants. Maize is notorious for sucking the nitrogen out of the soil; beans, on the other hand, supply replacement mineral nitrogen back into the soil: essentially, these are the effects of crop rotation without actually having to rotate crops. Overall, say crop scientists, more protein and energy are produced by intercropping three crops in the same space than that achieved by modern monocultural agriculture.

Maize maximizes photosynthesis, and grows straight and tall. Beans use the stalks for structural support and to gain greater access to sunlight; at the same time they bring atmospheric nitrogen into the system, making the nitrogen available to maize. Squash performs best in shady, humid places, and that is the type of microclimate provided by the corn and beans together. Further, squash decreases the amount of erosion that plagues monocultural cropping of corn.

Corylus avellana - Hazel tree

Latin plant name Corylus avellana Common plant name Hazel tree Plant type Deciduous tree Size (meters) < 4m Distinguishing features They have simple, rounded leaves with double-serrate margins. The flowers are produced very early in spring before the leaves, and are monoecious, with single-sex catkins. The nuts of all hazels are edible. The Celts believed hazelnuts gave one wisdom and inspiration. There are numerous variations on an ancient tale that nine hazel trees grew around a sacred pool, dropping into the water nuts that were eaten by salmon (a fish sacred to Druids) which absorbed the wisdom. The number of spots on the salmon were said to indicate how many nuts they had eaten. A Druid teacher, in his bid to become omniscient, caught one of these special salmon and asked a student to cook the fish, but not to eat it. While he was cooking it, hot liquid from the cooking fish splashed onto the pupil's thumb, which he naturally sucked to cool, thereby absorbing the fish's wisdom. This boy was called Fionn Mac Cumhail (Fin McCool) and went on to become one of the most heroic leaders in Gaelic mythology. Hazel wood was used by the dowsers to identify sources of fresh water underground.
