The month of June is full of satisfaction for the gardening enthusiast: the plants are in full development, there are still many spring blooms, but also those typical of summer are beginning to bloom. The days are getting longer and in the afternoon hours the heat starts to make itself felt. Ultimately, the garden will be at its best, but it will need almost daily care.
Sowing, divisions and cuttings
At the beginning of summer you can still sow many annual seeds (zinnias, nasturtiums, carnations) but it is the best time to proceed with the biennials, which will bloom the following year (eg lychnis, wallflowers, lunaria annua) For a quick germination we cover with vermiculite and a plastic film: it will be easier to keep high humidity.
We also proceed, if not before, with the extraction and division of the bulbs to spring flowering. We can then let them dry well in the shade and put them in boxes with sawdust, in a cool and dark place.
It is the ideal time to make herbaceous cuttings: lavender, rosemary, carnations, helichrysum, thyme, spirea, ceanothus … let’s place a portion of the apical part in a very sandy mix, cover with a plastic bag and move to the shade, keeping slightly moist. In a month the rooting will be complete.
- What are the Jobs of the Garden Month June? Certainly, those who are involved in gardening know that most of the work, this month, has already been completed but it is good to know which are still the most important jobs.
- Temperatures and climate should be optimal: growth is fast and there is still no stress from the typical summer heat and drought. Much, however, depends on the initial conditions…
Annual and perennial herbaceous plants
They require constant attention in order to remain beautiful for as long as possible and give always abundant blooms. It is important to be constant with the watering, adjusting to the rainfall, temperatures, exposure, soil and individual specific needs. We avoid stagnation and always distribute water in the morning: these are important precautions to avoid rottenness, leaf burns, thermal shocks and the spread of cryptogams.
To reduce the interventions (and also the weeding) it is a good habit to prepare a thick mulch of leaves or vegetable flakes.
Continuously flowering plants should always be cleaned of exhausted flower heads and should also be trimmed, to facilitate the tillering.
Trees and shrubs
In June, the water requirement becomes greater, particularly for plants planted in the autumn or in the previous spring. Irrigation is essential, but the deep development of the root system must be stimulated. To achieve this we recommend watering every 7-10 days, but very abundantly. To facilitate vegetative growth we give a second dose of slow release granular fertilizer and we always monitor that there are no deficiencies, especially iron chlorosis.
Some shrubs are beginning to fade: let’s work to eliminate the withered corollas for aesthetic purposes and not to stress the plant with the production of seeds.
At the end of flowering it is also time to prune the ancient roses and those shrubs that carry the buds on the branches of previous years. Let’s also take care of removing the suckers from all the plants.
Taking care of the garden in June: Meadow and déhors
In June, especially in the southern regions, temperatures start to be high and rainfall rather rare. However, it is also the period in which the open spaces are most likely to live. It is therefore important to ensure a well maintained and healthy lawn. If possible, we recommend that you irrigate every morning without stagnating. We also return to distribute a nitrogen fertilizer, but also equipped with a good amount of potassium and, possibly, iron.
The cuts must be frequent, but we never remove more than 1/3 of the total height. Then let’s avoid cuts that are too low: they stress the plants and cause them to turn yellow. We intervene immediately in case there are cryptogams.
To make the open spaces more pleasant, a nice idea is to insert herbaceous and fragrant shrubs (jasmine, honeysuckle, nicotiane, fragrant pea) and flowers that bloom in the evening (beautiful at night, hypomea dawn, metel datura).
