Updated May 31, 2024 at 2:11 pm

Between irises, poppies, wisteria and broom, the garden offers a magnificent array of colorful flowers, while introducing the harvest season (strawberries, cherries, lettuces, radishes, etc.). With the risk of frost now gone, it’s time to schedule waterings! Direct seeding and transplanting require hydration several times a day. A little subtlety: sandy soils should be watered little but regularly, while heavy and clay soils should be watered a lot but less often. Finally, we do not hesitate to mulch the soil after weeding it to counteract drought.

WHAT TO DO IN THE ORNAMENTAL GARDEN IN JUNE?

flowers

• When the oriental poppies and columbines bloom, install semi-hardy plants bought in pots: pelargoniums, fuchsias, anthemis, bidens, dimorphotheca.
• Regularly remove faded flowers in flower beds so that the plants are not exhausted by producing seeds unnecessarily.
• Pick the sweet peas as you go.
• Thin out annual flower seedlings: cosmos, lavatera, cornflowers.
• Recompose the beds by removing biennial plants and bulbous plants at the end of their life.
• Until mid-June, plant fast-growing annual flowers: nasturtiums, sanvitalias, alyssums, etc.
• Plant pots of annual or semi-hardy flowers bought in pots in the ground: dahlias, rudbeckias, tobacco, verbena, etc.
• When the lilac blooms, sow large-seeded annuals in pots: dwarf beans, ornamental corn, sunflowers (Helianthus annuus), nasturtiums (Tropaeolum), etc. Wait until the soil reaches a temperature of at least 15°C to sow annuals like this. such as amaranths and castors.
• Transplant the root cuttings of perennials when they are well rooted.
• Remove wilted leaves from oriental poppies.
• Thin out spontaneously reproduced plants: lady’s mantle, agastache, bronze fennel, foxgloves, cockroaches, Sisyrinchium, etc.
• Stack clumps of delphiniums and perennials with long, flexible stems, dahlias, as well as low, loose plants such as hybrid erigerons or prickly pears. Corset the tufts of herbaceous peonies without over-tightening.
• Brush out the cloves regularly.
• Before mid-June, pinch autumn-flowering varieties of asters, autumn chrysanthemums, hybrid phloxes, valerians, hybrid erects, hellenes, suns, eupatoriums, cataleptics, monarda, loosestrife, etc.
• Remove weeds and faded iris florets. At the end of their flowering, cut the flower stalks above the leaves.
• Mow the foliage of lungworts and confres with variegated foliage to reveal fresh new foliage.
• After they have finished blooming, cut off the clusters of delphiniums, lupins, erects, mountain sycamores, marigolds, lady’s mantles, perennial geraniums, hymns, etc.
• Cut half the stems of bellflowers and sub-shrubs such as thyme, helianthus and iberis.
• Using a small trowel, remove the clod, a sign of compacted soil.
• Until mid-June, plant gladioli every two weeks to get consecutive blooms.
• Remove dead bulbs, hybrid tulips and hyacinths. Allow the foliage of tulips and hybrid hyacinths to yellow and dry before digging them up and storing them in late June.
• Treat lilies against leaf beetles until September.
• Protect the base of the rose bushes and spread mulch. Remove faded flowers from non-blooming rose bushes and prune as soon as they finish blooming. Prune liana roses.

Trees and bushes

• Water heather plants regularly. Clean them after they have finished blooming.
• For blue hydrangeas, water with a bluing product or potassium alum, or incorporate crushed slate into the soil.
• Remove shoots that appear on the trunk of grafted trees. Cut off the faded inflorescences of shrub euphorbias. Remove green shoots from bushes with variegated foliage.
• Cut the santolinos into balls. Pinch the candles from the rock pines. Remove shoots or suckers at the base of lilacs, sumacs, ailants, purple hazel trees. Remove toxic laburnum fruits after flowering. Prune dead buddleias. Perform pruning on flowerless cyst bushes.
• By mid-June, layer the stems of certain shrubs such as lavender, bush lavender, azalea, magnolia and labrumnum.
• Take cuttings under cover of oleanders, hydrangeas, spireas, spring viburnums, bush honeysuckle, lilacs, rosemary, barberries, evergreen ceanotes, etc. Cut down dogwoods, witch hazels, magnolias and rhododendrons.
• Detect the presence of scale insects on hydrangeas, camellias, laurels, etc., and red spiders on rock firs.
• Limit the expansion of climbing plants. Prune honeysuckle branches infested with aphids and spray with black soap if necessary.
• After they have flowered, prune formal hedges from spring flowering shrubs. Refresh holly, boxwood, barberry, hornbeam, hawthorn, santolin hedges, etc.

Lawn

• After the heat is installed, mow the lawn once a week after checking the sharpness of the blades. If you are unable to do this, mow in two stages: once at the high blade position, then another at normal height two or three days later. In areas planted with naturalized bulbs, wait until they have formed their seeds and their foliage has dried so as not to damage them. After each mowing, clean the mower.
• Water abundantly every four or five days just to encourage the roots to seek water deeply, a guarantee of better resistance to drought later.
• Use a natural weed killer and/or remove the most visible weeds by hand.
• Fertilize lawns every two months with a specific fertilizer, mineral or organic.

Basin

• Feed aquatic plants.
• Maintain the pool: remove green algae and weeds, eliminate duckweed, repair any leaks, clean the strainers and pump filters.
• When the young leaves of the water lily appear, install aquatic plants such as lotus or other water lilies in large openwork baskets. If voracious fish live in the pond, cover the pots with mesh to protect the tender leaves. The experienced gardener can grow exotic water lilies with abundant flowering in large containers to be placed in the pond as soon as the water exceeds 20 °C.
• In case of invasion, cut the cane stumps below the water surface.
• Divide old clumps of water lilies, semi-aquatic or bank plants such as water lilies.
• Advice from “Petit Larousse du jardin month by month” (ed. Larousse): if the water is cloudy, install oxygen plants or a pump equipped with a water spray. However, be careful to direct the latter correctly, aquatic plants do not appreciate agitated water.
• Clean pumps and filters regularly.
• Monitor the water level regularly.
• Keep herons, predators of pond fish, away with plastic bait or a large net on the surface of the water (a few black threads may be enough)
