A plant journal that remembers the messy details.

Plant Diary keeps care actions, plant logs, photos, health changes and future plans attached to the plant they belong to. Instead of separating watering reminders from notes, photos and treatment history, each plant profile becomes a practical care record you can return to before deciding what to do next.

• Care action history
  Record completed watering, feeding, pruning, repotting, pest treatment and custom plant care tasks.
• Photo notes
  Attach photos to growth updates, symptoms, recovery progress and seasonal changes.
• Health context
  See health changes beside watering, feeding and treatment history so each decision has context.

Garden tools: plant doctor, planting guide, seed box, crop rotation planner and garden shed.

Plant Diary also helps you decide what to grow, where to grow it and what is going wrong, with four garden tools that are free to try in the beta.

• Plant Doctor: what's wrong with my plant?

  A plant problem identifier for 138 common pests, fungal and bacterial diseases, viruses, nutrient deficiencies and weather stress. Narrow it down by plant, where the problem is, what you see, the colour and the leaf pattern, compare photos, then follow a treatment plan that starts with the gentlest fix.

• Planting Guide: what to plant this month

  A vegetable planting calendar for your climate zone and hemisphere. See what to sow from seed, plant as seedlings and harvest each month across 145+ vegetables, herbs and fruit, then add a crop to your garden with watering, feeding and harvest reminders ready to go.

• Seed Box: a seed inventory app

  Keep every seed packet in one place, see which seeds you can sow now for your zone, and spot packets that are past their best. Seed lasts about 1 year for onion and parsnip, 3 for carrot and beans, 4 for tomato and lettuce and 5 for squash and cucumber when stored cool and dry.

• Crop rotation planner: what to grow where next

  Put your vegetable beds on an interactive rotation wheel. Plant Diary follows the classic four-group order (legumes, leafy greens and brassicas, fruiting crops, then roots and onions), keeps each plant family out of a bed for three seasons and suggests what to grow next from your seed box and the Planting Guide.

• Garden Shed: which fertiliser for which plant

  Keep your fertilisers, seaweed tonics, pest and disease sprays and soil improvers in one place. Plant Diary reads the N-P-K on each label (nitrogen for leaves, phosphorus for roots, potassium for flowers and fruit), explains what each product is best for, matches it to your plants and fills the dose and timing into your feeding schedule.

Field notes for better plant decisions.

The Plant Diary blog supports the app experience with practical plant care guides, seasonal gardening ideas, pest control notes, container garden advice and plant care planning tips. Read the guide, then bring the next action back into your plant tracker, journal or care calendar.

• Plant care guides
  Learn how to adjust watering, feeding, pruning and plant health checks as conditions change.
• Garden journal ideas
  Use notes, photos and recurring tasks to build a useful record for houseplants, herbs, fruit trees and garden beds.
• Seasonal care planning
  Turn reminders into a care rhythm that fits indoor plants, balcony gardens and outdoor collections.

Plant care questions

• What is Plant Diary?
  A plant care app, plant tracker app and digital garden journal for watering reminders, custom care schedules, health notes, plant photos and garden tasks.
• Is Plant Diary free?
  Yes. Plant Diary is currently free while it is in beta.
• Can I use Plant Diary as a watering reminder app?
  Yes. Create plant-specific watering schedules, complete care actions and keep watering history attached to each plant.
• Can I track plant growth with photos?
  Yes. Add growth photos and notes over time to build a plant growth diary for each plant.
• How is Plant Diary different from a normal reminder app?
  Plant Diary also keeps plant profiles, growth logs, photos, health notes, garden tasks and completed care history.
• Can I manage a large plant collection?
  Yes. Plant Diary is designed as a plant collection tracker for growing collections, from one shelf to a full garden.
• Can Plant Diary help me plan crop rotation?
  Yes. Add your garden beds to the crop rotation wheel, record what grew in each one, and Plant Diary suggests what to grow next for your climate zone, keeping each plant family out of a bed for three seasons to stop pests and diseases building up.
• Can I keep track of my seed packets?
  Yes. The Seed Box keeps every packet you own in one place, shows which seeds you can sow this month for your zone, and flags packets that are getting too old to germinate well.
• How do I find out what's wrong with my plant?
  Start with where the problem is and what you see: yellowing, spots, holes, powder, sticky residue or wilting. Plant Doctor in Plant Diary narrows 138 common plant problems by plant, symptom, colour and leaf pattern, shows photos to compare against, and gives a treatment plan that starts with the gentlest fix.
• Why are my plant's leaves turning yellow?
  The pattern points to the cause. Older leaves yellowing evenly usually means nitrogen deficiency or overwatering. A green inverted V at the base of older citrus leaves, with the rest turning yellow, points to magnesium deficiency. Young leaves turning pale with green veins points to iron. Yellow speckling with fine webbing is often spider mites.
• What vegetables should I plant this month?
  It depends on your climate zone and hemisphere. The Planting Guide in Plant Diary works out your zone from your location and lists what to sow from seed, what to plant as seedlings and what to harvest each month, across 145+ vegetables, herbs and fruit. In a temperate southern garden in October, that includes tomatoes, beans, zucchini and basil.
• Does the planting calendar work in both hemispheres?
  Yes. Planting months shift by six months between hemispheres, so spring sowing shows in September and October in Australia and in March and April in the UK and US. The guide also adjusts for climate zones, from cool temperate to tropical and arid.
• How long do vegetable seeds last?
  Stored cool and dry, most vegetable seed stays good for 2 to 5 years. Onion, leek and parsnip seed lasts about 1 year; capsicum, chilli and sweetcorn about 2; carrot, beans and peas about 3; tomato, lettuce and beetroot about 4; cucumber, pumpkin, zucchini and radish about 5 (Purdue and Illinois Extension seed charts).
• Is there an app to organise my seed collection?
  Yes. The Seed Box in Plant Diary is a seed inventory app: add packets one at a time or paste a whole list, and each one is matched to the Planting Guide. It shows which seeds you can sow this month for your zone, how many packets you have and which are past their best, so you stop buying seeds you already own.
• What is crop rotation and why does it matter?
  Crop rotation means growing each vegetable family in a different bed each season. It stops soil pests and diseases that target one family from building up and keeps the soil fed. The classic four-group order used by the RHS and extension services is legumes, then leafy greens and brassicas, then fruiting crops, then roots and onions, then back to legumes.
• What should I plant after tomatoes?
  Avoid potatoes, capsicum, chilli and eggplant, because they are in the same nightshade family and share blight and wilt. In a four-group rotation, roots and onions such as carrots, beetroot, garlic and onions follow fruiting crops, and legumes follow those. The crop rotation planner in Plant Diary keeps each family out of a bed for three seasons.
• What do the N-P-K numbers on fertiliser mean?
  They are the percentages of nitrogen (N), phosphorus (P) and potassium (K). Nitrogen grows leaves, phosphorus grows roots and helps plants establish, and potassium supports flowers, fruit and resistance to stress. A 20-2-5 lawn food is a leaf grower, a 4-1-12 tomato food is for flowers and fruit, and 10-10-10 is an all-rounder.
• Which fertiliser should I use for tomatoes, citrus and leafy greens?
  Leafy greens such as lettuce and silverbeet want a high-nitrogen feed. Tomatoes want a balanced feed while they grow, then a high-potassium feed once they flower. Citrus wants nitrogen and potassium together, plus magnesium and iron. Keep high-nitrogen feeds off carrots and other root crops, because extra nitrogen makes the roots fork.
• Can I keep track of my fertilisers and garden sprays?
  Yes. The Garden Shed in Plant Diary keeps your fertilisers, seaweed tonics, pest and disease sprays and soil improvers in one place. It explains what each N-P-K is best for, matches products to your plants and fills the dose and timing into your feeding schedule.
