With movable plant shelter covers, seasons are extended to earlier in the spring and later in the autumn, with some cold-weather tolerant crops carrying on throughout the winter. With continual rotations, crop pests never gain the advantage of carrying over populations from the previous growing season with dependable food supplies to prey upon. In the tropics plants use the soil year round without the soil ever getting worn out or tired over millions of years. By continual enrichment of the growing soil through the worm-castings technique, the soil can be used as much as local environmental weather permit. Year round cropping is possible in many locales where it is not known presently.
Some crops permanently occupy their turf, such as rhubarb, asparagus, grape vines and orchard trees.
There are hedges of rose bushes, christmas trees and holly bushes screening the property from the road, providing privacy and windbreaks. The roses are picked in season for floral bouquets, and cuttings are taken for the propagation of new bushes for sale. Christmas trees and holly provide greens for seasonal decorations, wreaths, centerpieces, and a welcome infusion of cash in the dead of winter. Flowering quince bushes provide some of the first flowers of spring and branches of blossoms to sell to local florists. Hot house iris, lily, narcissus, daffodils, tulips, and orchids find ready customers in the pre-spring doldrums.
