Planning Your Planting Calendar

Do you have big growing plans for the year ahead? A planting calendar may be just what you need to stay on track, meet your goals, and enjoy impressive harvests year-round. In this handy article, LBS Horticulture will share the advantages of planting plans and how to create an effective schedule to guide you through each month of the year.

Before you grab your seeds and finest compost, it's good to have a solid action plan. Develop an allotment or greenhouse planting schedule to ensure sowing success.
What is a Planting Calendar?
A planting calendar is a valuable tool for keeping track of planting duties throughout the year – so you know what to sow, when, and where. It's especially beneficial if you aspire to grow many different crops, each with its unique growing conditions. You can plan out a handy guide and reference it throughout the year.
Most planting calendars will list out the months of the year and the following information:
- The seeds to sow in each month
- Whether you should sow the seeds indoors or directly outdoors
You can make your plan as simple or detailed as you like. Stick to the basics, or use your calendar as a source of all key information, such as transplanting times, sowing depths, plant spacing, and potential pests to watch out for.
Why Make a Planting Schedule?
A planting schedule is a great way to improve efficiency and organisation in the garden. Like an ordinary calendar, it helps you plan for events and prompts action. As a result, you can achieve the following benefits:
- Improved Harvests: A well-planned calendar ensures you sow at the optimal time for each crop, helping your plants thrive. As a result, you should gain healthier, tastier crops and higher yields.
- Plan for Crop Rotation: Knowing what you're growing and when helps you prepare for a successful crop rotation cycle.
- Enhanced Productivity: A planting schedule gives you time to prepare for each crop. You can begin stocking up on appropriate growing media, specific plant food, or pots and trays that will be most effective for starting your seeds.
Creating A Greenhouse or Allotment Planting Schedule in the UK

Interested in making your own planting calendar? One of the simplest ways is to gather all the packets of seeds you want to grow throughout the year and sit down to make a plan. Follow these steps to get started.
- Create a list or spreadsheet with a header for each month of the year. This outline will allow you to map out your planting schedule month by month.
- Check the instructions on each seed packet for the recommended sowing month or season.
- Based on the seed packet information, jot down each crop under the appropriate month in your calendar.
- When adding your crops to your list, note whether you should sow the seeds indoors or outdoors. You can also add any other relevant information or care conditions.
Now you have a basic planting schedule! You can leave it as is or transfer the information to a more detailed format like a digital calendar or planting planner.
