Il 1' modulo del Bosco Claudio Abbado a Ferrara durante il primo sfalcio primaverile, il momento in cui si puo' cogliere la bellezza dello sfalcio differenziato... Forse non in questo parco pubblico, forse altrove, si puo' introdurre tale cultura della cura dei prati nel nostro paesaggio urbano!
Quando ancora non si sapeva nulla di che cosa avrebbe portato con sè l'idea del "bosco"... era il 2013, appena tornato da Londra, un'immagine in testa da qualche anno, di giardino boschivo, gia' tutt'uno con l'idea di margine boschivo, i primi 20 metri di un bosco, quella fascia di pochi metri che tiene insieme un bosco alla campagna intorno e gli animali che ci sono dentro ed il disegno che, dunque, cominciava così.
Basta attivarlo con semi, qui e là, accelerare il processo fisiologico delle nostre città di riempirsi di fiori spontanei. Il tetto del mio vicino ora ha tulipani e centaurea nonché erbe varie. Certo, la guaina non sarà felice, mi si dice, ma in verità la comunità vegetale che si è formata tra le tegole di cotto antiche e bellissime di questa porzione di superficie orizzontale della mia città Ferrara non pare creare particolari problemi... L'acqua scorre bene e nessuno si è lamentato. Ancora.
Ecological Planting Design
Ecological Planting Design
What do these words mean? Some principles of ecological planting design. (from the book: "A New Naturalism" by C. Heatherington, J. Sargeant, Packard Publishing, Chichester)
Real structural plants marked down into the Planting Plan. The other plants put randomly into the matrix: No. of plants per msq of the grid, randomly intermingling (even tall plants). Succession through the year.
Complete perennial weed control.
High planting density. Close planting allows the plants to quickly form a covering to shade out weeds.
Use perennials and grasses creating planting specifications that can be placed almost randomly.
Matrix: layers (successional planting for seasonal interest) of vegetation that make up un intermingling (random-scattering) planting scheme: below the surface, the mat forming plants happy in semi-shade, and the layer of sun-loving perennials.
Plants are placed completely randomly: planting individual plants, groups of two, or grouping plants to give the impression of their having dispersed naturally. Even more with the use of individual emergent plants (singletons) that do not self-seed, dispersed through the planting.
An intricate matrix of small plants underscores simple combinations of larger perennials placed randomly in twos or threes giving the illusion of having seeded from a larger group.
The dispersion effect is maintained and enhanced by the natural rhythm of the grasses that give consistency to the design. They flow round the garden while the taller perennials form visual anchors.
Allow self-seeding (dynamism) using a competitive static plant to prevent self-seeders from taking over: Aruncus to control self-seeding Angelica.
Sustainable plant communities based on selection (plants chosen for their suitability to the soil conditions and matched for their competitiveness) and proportions (balance ephemeral plants with static forms and combinations such as clumpforming perennials that do not need dividing: 20% ephemeral, self-seeding plants, 80% static plants) of the different species, dependent on their flowering season (a smaller numbers of early-flowering perennials, from woodland edges, which will emerge to give a carpet of green in the spring and will be happy in semi-shade later in the year, followed by a larger proportion of the taller-growing perennials which keep their form and seed-heads into the autumn and the winter).
Year-round interest and a naturalistic intermingling of plant forms.
Ecological compatibility in terms of plants suitability to the site and plants competitive ability to mach each other.
Working with seed mixes and randomly planted mixtures.
Perennials laid out in clumps and Stipa tenuissima dotted in the gaps. Over the time the grass forms drifts around the more static perennials and shrublike planting while the verbascum and kniphofia disperse naturally throughout the steppe.
Accents: Select strong, long lasting vertical forms with a good winter seed-heads. Select plants that will not self-seed, unless a natural dispersion model is required.
Planes: if designing a monoculture or with a limited palette, more competitive plants may be selected to prevent seeding of other plants into the group.
Drifts: to create drifts of naturalistic planting that are static in their shape over time use not-naturalizing, not self-seeding, not running plants.
Create naturalistic blocks for the seeding plants to drift around. For the static forms select plants that do not allow the ephemerals to seed into them.
Blocks: use not-naturalizing species, in high densities, in large groups.
Select compatible plants of similar competitiveness to allow for high-density planting (to enable planting at high density in small gardens).
Achieve rhythm by repeating colours and forms over a large-scale planting.
