When to plant plant’s bulbs? A seasonal gardening calendar
The right time to plant plant's bulbs depends primarily on the species, the plant’s resistance to cold and the intended growing location. Some bulbs and tubers can be planted directly in the ground in autumn, while frost-sensitive varieties should be planted in spring or started earlier in pots. A seasonal calendar helps spread the necessary tasks throughout the year and provides plants with suitable conditions from the moment of purchase until winter storage.
In this article, you will learn:
· what determines the correct planting time for bulbs and tubers,
· which gardening tasks should be carried out in winter, spring, summer and autumn,
· when to start growing plants that are sensitive to low temperatures,
· how to care for bulbs and tubers after flowering,
· when to dig up planting material intended for storage.
All suggested dates should always be compared with the requirements of the particular variety, as there is no single universal planting date.
What determines the planting time for bulbs and tubers?
The most important factor is the selected species’ resistance to low temperatures. Plants that tolerate winter conditions well are often planted in autumn so that they have enough time to develop roots before frost arrives. Heat-loving varieties should only be planted outdoors once the risk of frost has passed.
The growing method also matters. Growth can be started earlier in a pot placed in a bright, protected room than in an outdoor flower bed. This solution is particularly useful when the gardener wants to produce established young plants that are ready to be moved to a balcony, terrace or garden.
Calendar dates should be treated as guidance rather than strict rules. Soil temperature, moisture levels and local weather conditions may shift the planting date by several weeks.

Winter: planning and checking stored plants
During winter, most gardening tasks take place away from the garden. This is a suitable time to plan flower beds, choose varieties and determine how much space individual plants will need. It is worth noting their mature height, flowering period and growing position requirements.
Plant's bulbs dug up in autumn should be checked regularly. Material stored in a well-ventilated place should not be exposed to moisture, frost or sudden temperature changes. Soft, mouldy or visibly damaged specimens should be separated from the rest.
At the end of winter, containers and well-draining soil can be prepared for plants that will be started under cover. However, not all varieties should be planted at the same time, as shoots that develop too early may not receive enough light.
Early spring: preparing for planting
In March and early April, preparation of the growing area can begin. The soil should be loosened, weeds should be removed and the area should be checked to ensure that excess water does not remain after rainfall. Plant's bulbs react particularly poorly to prolonged moisture around their underground parts.
Sensitive varieties can be planted in pots and placed in a bright room during this period. This helps accelerate root and shoot development without exposing the plants to night frosts. Watering should remain moderate until vigorous growth begins.
Late spring: the main planting time for heat-loving varieties
Once the risk of frost has passed, cold-sensitive plants can be moved into the garden. Decisions should not be based solely on the date in the calendar. If the nights remain cold, it is better to postpone planting or provide young shoots with suitable protection.
It is worth choosing plant's bulbs for spring and summer planting according to the conditions available in the flower bed or on the balcony. The MP Seeds range includes dahlia tubers, begonias and oxalis, among other options, so the requirements of individual plants should be compared before purchase.
Summer: care, watering and monitoring flowering
During summer, the main task is to maintain an even level of soil moisture. Plants grown in containers usually need to be checked more frequently than those growing in the ground because soil in pots dries out more quickly. However, excess water can be just as harmful as insufficient watering.
Once the shoots have developed, fertilisation suited to the needs of the selected variety can begin. Tall plants may require support, especially in locations exposed to strong winds. Removing faded flowers helps maintain the attractive appearance of the arrangement, provided that the care requirements of the particular species do not call for seeds to be left on the plant.
Tip: Before watering, check the soil moisture, current weather conditions and the condition of the leaves.
Autumn planting of cold-resistant varieties
Autumn is the planting season for species that require a period of cold or overwinter well in the ground. They should be placed in the soil early enough to begin developing roots, but not so early that they produce too much above-ground growth before frost arrives.
The soil should not be frozen or waterlogged. After planting, a layer of mulch can be added if required by the species and local conditions.
MP Seeds supports gardening plans that develop in harmony with the natural rhythm of the seasons.
A calendar worth adapting to your own garden
The best time to plant plant's bulbs results from combining the recommendations for the variety, local weather conditions and the chosen growing method. Starting plants earlier in pots may accelerate the development of heat-loving species, while cold-resistant varieties can begin rooting in autumn.
Keeping brief notes on planting dates, the appearance of the first shoots and the start of flowering makes it easier to plan future seasons. After one or two years, you can develop your own calendar tailored to the specific conditions in your garden or on your balcony.
FAQ – frequently asked questions about planting times for plant's bulbs
Can plant's bulbs be planted in spring?
Yes, spring is the correct planting season for many bulbs and tubers, especially frost-sensitive species. Outdoor planting should begin only after the risk of frost has passed.
Can bulbs and tubers be started earlier in pots?
Yes, starting them earlier in containers allows roots and young shoots to develop in protected conditions. However, the plants should be gradually hardened off before being moved outdoors.
When should frost-sensitive tubers be dug up?
Cold-sensitive tubers are usually dug up after the growing season and before severe frosts arrive. The exact timing depends on the species, the condition of the above-ground parts and local weather conditions.
