After talking about the importance of covering the ground, so it can remain moist and dark, now will face the theme of intercrossing between plants.
Why do plants need? The plants are associated for more than one reason based on the relationship which set out:
Nutrients (eg. Bean fixed nitrogen – Maize it is a high consumer)
Support (eg. Japanese Chauchat – Pine these plants are accepted only if between them there is an exchange of benefits and if the vine does not affect the other)
Shadow (eg. winter lettuce in the shade of pumpkin, corn, sunflowers and tomatoes, associated resist excess heat and cold)
Ways to protect themselves may be different, let’s start with:
interferences: Corn – Pumpkin everyone has their diseases and disturb each other, have some small holes but are not considered anything serious.
The plants “bait”: Eggplant Potato protects against disease because it is attacked first.
Plants “bait” sacrificed: the tomato basil protects from the moth and worms (gusano de cuernos)
Plant “bait” with pleasure: Chrysanthemum and the radicle are plants bait to attract aphids, except that unlike the eggplant this type of plant does not die but keeps stable community of aphids.
Plants “trap”: the Umbelliferae are breeders of arachnids, small wasps that feed the Labiatae keep away bugs, aphids, watercress spiders.
Repulsion: smells that keep pests away from other plants. Mint-tomato / potato-radish
Plants that are associated with plants protectors are more luxuriant, since they use more energy for growth and improve that to defend themselves.
Stimulation: the roots of each plant have specific nutrients released into the soil, the failure caused by the same plant, but the resulting toxins are stimulating for other plant species.
At this point, if we aren’t expert in gardening or botany, comes to our mind: how do I know which plants link and what not?
There are various criteria, one of many, probably the most reliable, are the “tables of similarities”, indicating which plants can be associated and what is not. Others are “theory of plate” or anything that you bind the garden you bind the plate and vice versa, but it is more an expression that something true, then we have “mismatched pairs” or groups between plants are more favorable very different from each other (lettuce-sunflower / pumpkin-corn).
In the book we find the tables of the similarities and some knowledge of botany to learn more about the families of plants and at least have the knowledge to link them.
