As of 13 August 2026, AI can create a seasonal gardening calendar for your UK garden.

What to actually do

1. Do it yourself

   The route this page recommends

   A chat interface, no skill needed, and roughly 30 minutes until you can act on the result.

   How to actually do it

   1. Open a chatbot and gather your town or first part of postcode, garden aspect, soil type, growing space, plants, crops, available equipment and the time you can spend.
   2. Paste the prompt and replace every bracketed slot with your own information, using 'none' where a category does not apply.
   3. Ask the chatbot to produce the month-by-month calendar and the weekly checklist, then answer any clarification questions with details about your garden.
   4. Open the seed packets and plant labels for the crops and plants in the calendar, and compare their sowing, planting, spacing and pruning instructions with the draft.
   5. Check location-sensitive tasks against current RHS guidance and your local frost and weather conditions before moving plants outdoors or sowing tender crops.
   6. Delete tasks that do not fit your space, equipment, restrictions or available time, then copy the remaining calendar into a paper diary or digital calendar with reminders.

   Prompt

   Create a practical seasonal gardening calendar for a UK garden.
   
   My location: [town or first part of postcode]
   Garden type and aspect: [for example, small south-facing garden, allotment, balcony]
   Soil or growing medium: [for example, clay soil, sandy soil, raised beds, containers]
   Available space: [describe beds, containers, greenhouse or polytunnel]
   Plants and crops I want to grow: [list them]
   Plants and crops already growing: [list them]
   Time available: [for example, two hours at weekends]
   Tools and equipment: [list them]
   Restrictions: [for example, no pesticides, pets, limited lifting, budget limits]
   
   Make the calendar month by month for the UK. For each month, list only tasks relevant to the information above and label each task as sow, plant, protect, prune, feed, water, harvest, tidy or plan. Separate indoor, greenhouse, container and outdoor tasks. Give approximate timing rather than pretending that one date fits every UK location. Highlight tasks affected by frost, soil temperature, rainfall or local weather. Include a short list of jobs that are easy to miss.
   
   Do not invent plants, equipment, garden conditions or local weather. If information is missing, ask concise questions before making assumptions. For each crop or plant, state when the advice should be checked against the seed packet, plant label, RHS guidance or current local conditions. Put uncertain or location-sensitive recommendations in a separate section. Finish with a simple weekly checklist for the next month.

   Open it prefilled in ChatGPT or Claude, or copy it into Gemini, which takes no prefill link.

2. Use a tool built for this

   Second choice

3. Hand it to a person

   The distant third

   A person who owns the outcome does this end to end, worth it when the failure is dear.
