Video: Florist's Calendar For May
In May, a full-fledged gardening season finally begins. The weather allows not only planting even the most cold-resistant crops, but also making up spectacular potted gardens, decorating garden landscapes with summer houses in ampels and taking out the first pot and tub exotics in the open air. There is practically no time left to admire the kaleidoscope of colors and forms of luxurious May flowering, because all the main work on the care of not only useful, but also ornamental plants is at its peak. This month, we must not forget about seasonal crops, and about shrubs and woody ones. Although most of the work will still concern herbaceous perennials.
All attention to the main stars of garden ensembles
Herbaceous perennials in all their glory, from the most modest and small in size to quite aggressive and wildly growing giants in May, take the most time and effort. These plants, playing in flower beds and in flower beds, both as grateful partners and background crops, as well as textural, flowering, spectacular accents, need the most attention this month. If spring dragged on, warm weather had to wait until May, then almost all gardening work with perennial stars has to be postponed altogether until this month.
But even if you do not plan big changes in the structure and design of the garden, it is in May that you start vegetative propagation and rejuvenation of old clumps. At the beginning of May, focus on the division, reproduction and planting of all the main decorative flowering perennials - delphinium, phlox, astilbe, pyrethrum, host, etc. However, because of the later start, funkia is better to divide in the third decade of May. When dividing adult perennials, make sure that at least 3-5 buds and a good bundle of roots remain in each division.
The main front of work with perennials is associated with the creation of new and correction of existing compositions. Works on partial replacement of plants, reconstruction of plantings, rejuvenation of ensembles, introduction of new accents, change of colors, complete replacement of decorative compositions or creation of new flower beds, ridges, mixborders and landscape groups are best carried out in May.
There will be other planting concerns in May. New conifers can be planted in the garden almost until mid-May, and if the plants are sold in containers - until the end of the month.
Perennials such as Gaillardia, Sycamore, Phlox, Pyrethrum, and Astilba can also be cut this month. Young twigs with a "heel" about 5-10 cm long are rooted in sand or high-quality soil, deepening by 1.5-2 cm and maintaining stable humidity and greenhouse conditions.
It's time to plant the first bulbous
In May, the first bulbous digging begins. Small-bulb crops, such as spring plants, snowdrops, bluewoods and muscari, this month can be multiplied, divided nests, moved to a new place, carefully separating individual bulbs or their groups. Plant the plants on new sites prepared in advance immediately.
Sowing in the soil and planting seedlings
May is the main month for sowing directly into open soil for all perennials and annuals, as well as most annual vines that prefer to sow not for seedlings. Directly at the site of cultivation this month, it is better to sow on previously improved and treated areas of the garden. Most ornamental plants prefer preliminary sowing on the so-called seed beds, although for many summer planters, sowing can be carried out directly in the decorative compositions themselves, followed by thinning the seedlings.
The first decade of May is considered the optimal time for sowing, but you should always be guided by weather conditions. In the third decade of May, they begin sowing in open soil of biennials intended for flowering next year - bells, foxglove, mallow, Turkish carnation and other biennial stars.
This is a wonderful month for planting most of the herbs. Since they very quickly lose germination, before direct sowing on flower beds and in flower beds or on decorative beds, medicinal herb gardens and landscape plantings, it is imperative to check the germination of each batch of seeds. In May, it's time to replenish decorative compositions with vegetables or berries, spicy herbs from the garden, unless of course you want to try all the charm of mixed design. Strawberries, thyme bushes or oregano, for example, will look great among classic ornamental plants.
Also, during the first half of the month, you can continue to plant in the ground the bulbs of gladioli and other corms wintering outside the soil. Before planting directly, you need to check the stocks of planting material again, sort the bulbs and tubers, clean them of scales and other debris and treat with a weak solution of fungicide or potassium permanganate.
Since the transfer of seedlings from premises to the soil can be carried out only after it has warmed up enough, traditionally all work with pre-grown seedlings of both annual and perennial crops is carried out in May. The most cold-resistant plants that prefer earlier sowing dates for seedlings - Levkoy and Shabo carnations - can be taken out first.
They are not afraid of even small frosts. At the very beginning of May, seedlings of such plants as ornamental beans, hops, morning glory, dolichos and other climbing plants are traditionally transferred to a permanent place. In the first half of the month, following the "pioneers", you can take out and plant seedlings of godetia, lobelia, snapdragon, lobularia, chrysanthemums, ornamental cabbage, scabiosa and other cold-resistant annuals. Only in the second half of May can you start planting Gaillardia, Nirembergia, Verbena, Coreopsis, Asters and Rudbeck.
Even in May, it is necessary to observe all safety measures when planting seedlings. Remember that plants should be hardened for at least 1 week before being transferred to a permanent location. For capricious annuals, it is better to increase this time to 2 weeks.
Potted gardens in all their glory
Some summer plants such as calendula, snapdragon and nasturtium can be sown directly into containers and boxes for balconies and window sills, terraces and seating areas. Under the May sun, they will sprout quickly enough and will actively start growing.
In May, you can start active transplanting of seedlings of summer houses and balcony plants into ampels, containers and pots. Daisies and pansies are planted first, then less cold-resistant annuals. It is extremely important for the plants to provide a good drainage layer and a quality substrate. A week after planting, you need to begin to carry out the first feeding and the obligatory pinching of the shoots to thicken the bushes and form more beautiful and lush compositions. This month make up all the main potted gardens on the terrace, balcony, recreation areas.
Focus on basic care components
If in April it was only about the initial gardening work, soil preparation, unwrapping the plants, the start of the feeding season, and care was practically reduced to pruning, then in May the season begins for full and obligatory care of most ornamental garden plants. It is in this month that regular watering starts, and most of the other classic procedures for the care of flowering and decorative leafy pets.
All the main spring stars from among the bulbous, including daffodils and tulips, need regular watering at the slightest drought. Access to moisture is necessary not only for colorful flowering, but also for the normal development of the bulbs, preparing for the next cycle and dormant period. If there is not enough rainfall, the soil for these plants should be watered so that it is soaked to a depth of about 20 cm. 1-2 waterings in May will guarantee normal ripening of the bulbs. But at the same time, care should be taken not to create too humid conditions, to maintain only a stable environment for the full development of bulbous plants.
Watering will be needed not only for bulbous, but also for other flowering crops. For all spring flowering plants without exception, it is carried out in accordance with the control of the level of natural precipitation. On cool days, even the most capricious plants practically do not need watering, but it is better to provide plants with additional procedures in sunny, dry weather. Watering is especially important for flowering shrubs and perennials, which were planted only this spring. The younger the plants, the more they are susceptible to drought during this period and the more dependent on your care.
This month, feeding is also carried out for all flowering shrubs and perennials. If you have not done this before, then for all ornamental plants it is better to carry out spring feeding with complex or nitrogen fertilizers that stimulate active growth. Depending on the preferences of a particular species and variety, the timing of flowering, this month, both repeated fertilizing with nitrogen fertilizers and procedures are carried out at the budding stage or before flowering. For bulbous potassium-phosphorus fertilizing is carried out before the beginning of flowering, if it is late or absent altogether and immediately after the end of flowering (together with abundant watering).
Do not forget to monitor the cleanliness, attractiveness of flower beds and beds, always maintain a neat and well-groomed type of planting. On all decorative compositions, weeds actively develop and grow rapidly in May, and flowering plants only add to the hassle. During this month, especially if you do not resort to mulching, remove even small weeds in a timely manner, in no case letting them bloom, and promptly monitor the removal of dry foliage and wilting inflorescences.
Despite the fact that the mulching layer is usually created much earlier, you can do it in May after careful weeding. Begin to carry out loosening of the soil, especially after heavy rainfall, and for all flowering crops.
Pay attention to perennials that bloom this month. For all types of irises, astilbe and other plants, it is advisable to add soil in time, not allowing the rhizomes to be exposed.
The main scope of work on pruning ornamental crops is already being completed by this month. In May, only perennial plants and seasonal accents that are finishing their flowering are cut off. Mandatory cutting of peduncles is needed, in particular, for berry, adonis, alissum, liverwort, carpet phlox, rezuha and other primroses. It is advisable to prune before seed ripening (except for those varieties that you want to try to propagate by seed).
Individual garden plants need special May care
- in pines, it is recommended to pinch young growths, removing up to 1/2 the length of the candle-like formations in order for the young needles to open faster and more interesting crown shapes to form;
- in summer-flowering phloxes, it is necessary to cut out all weak shoots;
- in this month, roses need increased care and careful care, which not only feed and water, but also conduct at least weekly foliage inspections.
Full-fledged active lawn care begins in May. Regular haircuts usually start this month, if, of course, the weather has allowed cleaning earlier. By this time, the lawn must be cleaned of felt and debris, and the first cleaning mow should be carried out, which is best dealt with before the beginning of the last month of spring. Trimming should be complemented by starting regular watering. But in May, you can continue to work with the edges of the lawn and fill the bald spots with new grass.
May is considered the first month suitable for planting new lawn areas. Moreover, areas for green lawns must be prepared in advance, not just carefully leveling and digging up the soil, but also achieving an absolutely flat surface with the help of a special roller or board. After preliminary application of special fertilizers to the soil, leveling and watering, sowing is carried out by scattering the seeds with a special seeder or manually according to the frequency recommended by the manufacturer.
After sowing, the seeds can be simply rolled up or slightly covered with soil. Young grasses should be allowed to rise to a height of 6-10 cm, and only after that the first high cut should be done. The lawn is cut to the recommended height only the second time.
We prepare the wintering tubs and pots indoors for the callout
In May, it is not yet time for most plants to move to fresh air. Only cold-resistant and hardy plants of "our" assortment - conifers, evergreen crops and perennials - can be taken out into the garden. Focus on temperature. On warm days, plants can be taken out into fresh air, immediately removed or covered at the slightest threat of frost.
But leaving is still the main thing. All garden pot and tub plants must already undergo a mandatory procedure for transplanting, transshipment or replacing the topsoil. If you didn't manage to do it earlier, be sure to set aside time for these works. Particular attention should be paid to perennials that grow in a potted culture and those that you are just planning to plant in containers, using cuttings from large clumps in flower beds.
For them, the containers are increased by 2-3 sizes (not less than 10 cm), because the active growth of horticultural crops accustomed to open soil does not allow increasing the containers annually by only 2-5 cm, as for ordinary exotic plants. When transplanting for plants, drainage must be laid, the soil mixture is selected only according to the individual preferences of each species.
For crops that are planned to be used for garden decoration, planting in containers is slightly different from indoor crops. Leave at least 2 cm from the top edge of the pots, otherwise you will not be able to effectively water plants that are in the hot season in the open air.
In May, it is necessary to start active care for all plants - to provide them with systemic irrigation and spraying for the fastest possible adaptation. Top dressing for all container and potted perennial exotic crops begins to be carried out no earlier than 3 weeks after transplanting, but in May it is better to transfer them to the "summer mode".
Don't forget about plant protection
Despite the fact that in May they are already actively starting to plant plants and all work is at its peak, the weather can still unpleasantly surprise with late return frosts. Always keep a supply of nonwovens and other emergency plant cover. In case of too sharp a drop in night temperatures, protection may be needed both for the most capricious flowering plants and newly planted young seedlings or cuttings.
It is from May that work begins to protect the most "mouth-watering" garden ornamental crops on flower beds from slugs, which love to feast on young leaves. Check your stocks of traps, insecticides and fungicides, if necessary, replenish the range of drugs with which you can quickly fight pests and infections at the first sign of their appearance.
For the most capricious and unstable varieties of roses and other shrubs, carry out preventive spraying this month to protect against powdery mildew, rust and other diseases.
