In brief: A gardening calendar organizes seasonal gardening tasks from January to December: in spring you sow and prune, in summer you water and harvest, in fall you plant and protect, and in winter you plan and maintain your tools. Soil, plant type, and weather matter more than a fixed date.
A gardening calendar brings order to seasonal gardening tasks. At a glance, you can see when sowing, planting, pruning, maintenance, and harvesting are due. At the same time, the plan remains flexible: a cold April delays planting, while a warm February speeds up new growth.
So observe the soil, weather, and plants regularly. The location is just as important as the plant type when deciding on the right time. Use this monthly plan as a practical guide, but adapt it to your region and the conditions in your garden. Find more ideas for your gardening year and outdoor projects in our relevant product range.
What should you do in January and February?
January: Check tools and protect the soil
The garden is often dormant in January, but your planning starts now. Check your seed supplies, create a crop rotation, and note which beds were heavily used the previous year. This helps prevent the same plant family from growing in the same place every year.
Inspect spades, shovels, hoes, and garden shears. Remove soil, dry the tools thoroughly, and oil moving metal parts. Sharpen blades before the first pruning jobs are due. Well-maintained basic equipment makes every later task easier. Add suitable garden tools in good time.
Avoid walking on frozen or very wet beds whenever possible. Your footsteps compact the soil and reduce air circulation. Remove only plant debris that was diseased. Healthy stems and seed heads provide food for birds and shelter for insects.
February: Prune trees and shrubs and prepare the first sowings
At the end of February, you can thin out many trees and shrubs on a frost-free day. Remove dead, diseased, or crossing branches right at the base. Prune early-flowering shrubs only after they have flowered, so you preserve their buds and an early food source for insects.
In a sheltered area, start slow-growing plants such as peppers, eggplants, and celery. Use clean seed trays, loose potting soil, and a bright location that is not too warm. Turn the containers regularly so the seedlings grow straight.
- Check cold frames, greenhouses, and raised beds for damage.
- Order seeds for vegetables, herbs, and summer flowers.
- Check potted plants in their winter quarters for dry soil and pests.
- Plan paths, the compost area, and irrigation for the coming season.
Expert tip
Keep a brief gardening journal. Record the sowing date, variety, location, start of the harvest, and unusual weather conditions. After one season, you will see which varieties grow reliably in your garden and when your beds are actually free of frost.
What gardening tasks are needed in March and April?
March: Prepare beds and sow hardy plants
As soon as the soil has dried out, clear the beds carefully. Loosen the top layer with a hoe or cultivator without turning over wet soil. Lightly work mature compost into the soil and remove perennial weeds, including their roots.
When the weather is suitable, sow radishes, carrots, spinach, peas, onions, and hardy lettuces directly in the bed. Mark the rows and varieties so you can weed confidently later. Row cover protects early sowings from cold nights and helps them get off to a faster start.
Divide vigorous perennials that have become overcrowded. Replant the divisions immediately and water them thoroughly. Also check fruit trees for frost damage and secure young shoots to sturdy stakes.
April: Harden off plants and care for the lawn
Many plants begin growing rapidly in April. Gradually acclimate young plants started indoors to sun, wind, and cooler temperatures. Place them outside in a sheltered spot during the day at first, and bring them back inside if frost is expected.
Mow the lawn for the first time when the grass blades are dry and have grown enough. Remove leaves, moss, and dead patches. Overseed bare areas, press the seed down lightly, and keep the surface evenly moist.
Perennials, berry bushes, and many trees and shrubs can now be planted. Water slowly and thoroughly after planting. A layer of mulch made from leaf compost or bark compost retains moisture in the soil and slows the growth of new weeds.
Important note
Do not plan tender plantings by the calendar alone. Late frosts can destroy young shoots and blossoms. With tomatoes, cucumbers, zucchini, and basil, wait until the local risk of frost has passed or keep row cover ready. For many plants, wet soil is more dangerous than a cool night.
For sowing, planting, and maintenance, suitable garden and plant supplies are well worth having. Clean plant pots, labels, plant ties, and a good growing medium save time later.
What does your garden need in May and June?
May: Plant after the last frost and encourage healthy growth
Once the last hard frosts have passed, you can move tomatoes, peppers, cucumbers, pumpkins and basil outdoors. Choose a warm, sunny spot and leave enough room between plants for good air circulation. Stake tall plants when you plant them to avoid damaging their roots later.
Mulch bare beds once the soil has warmed up. You can use grass clippings in thin layers, provided they are seed-free and not too wet. Alternatively, use well-rotted compost or another suitable organic material. Fertilise when needed rather than guessing. Apply fertiliser for garden plants selectively and according to the crop.
Sow beans, Swiss chard, carrots, beets, herbs and annual flowers. Thin seedlings early if they are growing too close together. Pull small weeds before they set seed and compete with your plants for water and nutrients.
June: Water, support and harvest
In June, check beds, containers, and newly planted shrubs and trees regularly. Water slowly at the roots instead of briefly wetting the leaves. Tomatoes, cucumbers and zucchini are particularly sensitive to uneven watering. For tomatoes, remove side shoots as appropriate for the variety and loosely tie up the main stems.
Harvest lettuce, radishes, herbs, strawberries and early-season berries regularly. Pick zucchini while they are young for the best flavour, and the plant will keep producing. Deadhead roses and perennials if you want to encourage a second flush of blooms.
Make room for family time in the garden: If children use the garden, plan paths, shade and a soft, obstacle-free play area. For a play area, you could consider
“A garden responds to the weather and to each plant's stage of growth, not to a fixed date. Check soil moisture, temperature and new growth before sowing or planting.”
How do you care for flower beds and lawns in July and August?
July: Use water wisely and protect your harvest
In midsummer, the water supply can make or break your harvest. Check the soil a few centimetres down before watering. If it is dry at that depth, give beds, containers and newly planted shrubs and trees a thorough watering. Whenever possible, water in the morning so plants can take up moisture throughout the day.
Water the lawn less often, but deeply. Avoid mowing it too short: longer grass shades the soil and helps it retain moisture. Raise the mower height during extended dry spells. With suitable garden irrigation, you can distribute water evenly and save trips with the watering can.
Harvest berries, beans, cucumbers, zucchini and herbs regularly. Remove any rotting fruit right away. Check cabbages, roses and fruit trees for aphids, caterpillars and fungal diseases. Remove individual affected leaves early, before the damage spreads.
August: Sow fall crops and give plants a break
In August, sow lamb's lettuce, spinach, radishes, winter onions and suitable Asian greens. Keep the seed rows moist until the seedlings are well established. Shade sensitive young plants on very hot days.
After the first bloom, lightly prune lavender without cutting into old wood. Divide spring- or summer-flowering perennials only when the soil is moist. Remove faded flower heads according to your garden plan, or leave the seed heads for birds.
Don't completely empty a full compost bin. Use mature compost in prepared beds and leave coarse material in the bin as a fresh bottom layer. Turn kitchen and garden waste regularly so air can reach it and it breaks down evenly.
Additional advice
Don't mulch right up to stems or tree trunks. Leave a few centimetres clear around the base so moisture doesn't linger. A loose layer five to seven centimetres thick reduces evaporation, protects the soil and helps rain soak in.
What should you plant and harvest in September and October?
September: Harvest, divide and replant
September is a time for both harvesting and fresh starts. Pick ripe fruit, store only undamaged produce and use any surplus promptly. If branches are weighed down, support them before they break.
Now is a good time to plant hardy perennials, berry bushes, shrubs and trees. The soil often stays warm as evaporation slows. Loosen the planting area, mix in compost and water new plants regularly for the first few weeks.
Divide overgrown perennials after they flower. Each division needs strong roots and several healthy shoots. Remove any weak or rotting parts, then replant the divisions at the same depth.
October: Plant bulbs and prepare beds for winter
In October, plant tulips, daffodils, crocuses, ornamental onions and other spring-flowering bulbs. Plant them in loose soil, using the size of each bulb as a guide for planting depth. Avoid waterlogged soil by choosing a well-drained spot or adding a drainage layer.
Remove diseased plants completely and keep infected material out of your regular compost. Healthy stems can stay in place until spring. Spread leaves in a thin layer beneath shrubs and over beds. On the lawn, rake up leaves regularly so the grass gets enough light and air.
Use the fall to make repairs. Secure loose climbing supports, replace damaged bed edging and clean plant pots. Empty rain barrels or protect them from frost if they are not frost-resistant.
How do you prepare the garden in November and December?
November: Protect plants from frost and store tools
In November, protect tender container plants, roses, and young trees and shrubs. Move containers closer to a house wall, wrap them in insulating material, and let excess water drain away. Evergreen plants also need some water on frost-free days in winter because they continue to lose moisture through their leaves.
Drain hoses, pumps, and above-ground irrigation components completely. Clean lawn mowers, pruning shears, and saws, dry them, and store them in a frost-free place. Keep rechargeable batteries dry and store them according to the manufacturer's instructions. This way, you can start work in spring without unnecessary repairs.
Protect young fruit trees from animal damage and check their supports after fall storms. Remove wet leaves from gutters, paths, and window wells. On garden beds, however, leaves can stay as a thin protective layer.
December: Plan the gardening year and let nature rest
There is little practical work to do in December. Use the time to review the past season: Which varieties produced good harvests? Where did the soil stay too dry? Which plants were too close together? Notes like these help you plan the next gardening year more precisely.
Make a shopping list for seeds, compost, plant supports, and spare parts. Sketch new beds roughly to scale, taking paths, shade, and the water source into account. Rotate vegetable families between beds to reduce soil fatigue and the risk of certain diseases.
When it snows, check the load on greenhouse roofs, canopies, and vulnerable trees and shrubs. Carefully shake snow from sturdy branches without breaking frozen twigs. Leave sheltered habitats for animals in place, and only intervene if safety or plant health is at risk.
“Leaves are not garden waste. As a loose layer, they protect the soil, support soil life, and provide shelter for many animals.”
With this gardening calendar, you can plan your gardening year month by month. Shift individual tasks if frost, rain, or dry weather makes it necessary. By observing your plants, protecting the soil, and maintaining your tools, you can work more efficiently and enjoy more reliable harvests.
Frequently asked questions
- What should a gardening calendar include?
- A gardening calendar includes monthly tasks for sowing, planting, pruning, watering, fertilizing, harvesting, and winter protection. Add regional frost dates, the location of your beds, and your plants' growth stages. This lets you plan seasonal gardening tasks flexibly and avoid working in unsuitable weather or on overly wet soil.
- What gardening jobs need doing in spring?
- In spring, loosen the soil, remove dead plant material, divide suitable perennials, and sow cold-hardy vegetables. After the last hard frosts, move young plants started indoors outside. Check the lawn, prune early-flowering shrubs after they bloom, and protect young shoots during cold snaps.
- How often should I water the garden in summer?
- In summer, water according to the soil, plants, and weather. It is better to water deeply and less often than to water lightly every day. Water in the morning or late evening if possible. Check the soil moisture 5 to 10 centimeters below the surface before watering. Mulch reduces evaporation and helps each watering last longer.
- What can I plant in the garden in fall?
- In fall, plant cold-hardy trees and shrubs, perennials, and spring-flowering bulbs. The still-warm soil supports root growth, while frequent rainfall helps plants get established. Choose frost-hardy varieties, work in mature compost, and water during dry spells. Protect tender plants before the first prolonged frost.
- What gardening jobs can you do in winter?
- In winter, plan crop rotations, order seeds, check tools, and repair beds, trellises, or greenhouse accessories. Remove only diseased plant parts, and leave healthy stems standing as shelter for insects. On frost-free days, check winter protection and water evergreen plants sparingly.
