Various creepers can flower a vertical space and thus enlarge the garden. It's up to you to choose the species best adapted to the places and your needs.
Works of the month
• Eliminate faded flowers on annuals, perennials and rosebushes to encourage re-growth and prolong flowering by avoiding seed formation.
• Slowly rooted muscaris, narcissus and fritillaries are best to be installed by the end of the month, or at least as soon as they become available.
• Transplant the irises and peonies. The resumption of vegetation will take place only in autumn (it is normal). Install each other by burying them barely.
• Treat lavatera, hollyhocks and other Malvaceae against flea beetles that turn flowers and leaves into lace.
• Harvest the guard potatoes. Let them dry well (dry) a few days before storing in a ventilated room. Burn the tops to limit diseases.
• Harvest the beans after you have coated the wrists with repellent ointment against chiggers.
• Plant the winter leeks at the beginning of the month; you will only bring fertilizer in early September.
• It is the peak season of semi-soft wood cuttings of trees and shrubs. Try a bit of everything in light soil and half shade.
Climbing plants should be selected according to the space to be covered, the accessibility of the places, the climate and the exposure. Do not fool yourself to get the best effect.
• Some of these creepers can have a huge development. For example, wisteria, ornamental vines or bougainvillea can easily reach 15 to 20 m long and as wide. To the weight shown (and to the corresponding wind catch) is added the strangling power of some (see next page). Be sure to adopt them only if you can easily access all parts to cut them regularly.
• It is often said that ivies destroy walls. This is also the case for species with stems with crampons: some bignones or climbing hydrangea. In fact, your walls do not fear anything as long as they are healthy and mortar-mounted. Only in walls already cracked, in dry or old-fashioned stones (lime and sand, or earth), the stems infiltrate and burst their support magnifying.
• For associations, only marry species of comparable powers and especially asking for identical care. Otherwise you will only get a mess. The roses and many clematis form happy pairs because they are cut and possibly treated at the same time and with the same products.
• Whatever the selected plants, be sure to offer a support adapted to the weight of the adult subject (this is even valid for perennials and annuals). It is extremely difficult to "take back" a well-developed climbing plant, except to prune it very short, which causes at least two to three years of vegetation to be lost.
Often from forest areas, creepers climb to gain light. The means to reach the summit are varied and we must give each plant the right way to rise. The sarmenting stems (soft and long, without specific hooks) must be trellised and attached carefully.
The same is true of thorny stems (roses, ornamental brambles...). The twining stems (honeysuckle, wisteria...) require a minimum of support on which to wrap, as well as plants with tendrils (vines, clematis...). The big winners are obviously the studded stems (ivy, bignones...) that apply alone on everything they find.
1 The virgin vines. They cover large areas and require good supervision not to win the roofs. Give them some sun, so that they are colored, but not too much to avoid powdery mildew.
2 The bignones. They bring a warm note in summer. The large-flowered forms have no spikes and a smaller development than the small-flowered bignones. We can all drive like wisteria.
3 Climbing hydrangeas. The north is a thankless show where they thrive however as ivy and honeysuckle. Slow at startup, they cover large areas, dotted with white flowers in June-July.
4 The false jasmine. Take them without hesitation for the perfume. Flexible, very long-blooming, persistent and very rustic, they cover for two to three months of fragrant flowers. They ask for hot, even hot exposure.
5 Ivies. Among the hundreds of varieties, remember only the best, fast growing and picturesque or colorful foliage. They support all floors and all exposures.
6 Wisteria. To drive precisely to pruning shears because of their exuberant character. Chinese species produce two or even three blooms between May and August.
A. In voluble plants (honeysuckle, wisteria...), it is the stem that wraps around the eventual support, which it absorbs sometimes completely.
B. Cleated stems are called "radicants". If the support lends itself to it (earthy cracks, for example). They marcot and return to the assault of more beautiful.
C. Tendrils are transformed leaves that allow plants to cling to the various substrates by immediately adopting the shape of their host.
Vegetable Boa: consider glycine as a tree with the corresponding power. Nothing resists his trunks. Think about it before installing it on a pergola, otherwise it will strangle and destroy the structure, even made of steel. Double the frame of a wooden trellis that will serve as a guide and will be sacrificed without too much state of mind.
