When each problem hurts

Read each row from left to right: it shows how one problem's conversations were spread over the year, so every row adds up to 100%. The top row does the same for all garden conversations. About 3 in ten garden conversations name one of these problems; the rest are plans, plant choices and show-and-tell. Over the whole year, lawns drew by far the most talk, followed by everyday watering, late frost and planting dates, and watering rules.

Plants lost or dying

About 5% of gardening conversations are about a plant that died or is dying. Only clear mentions are counted, so this is a lower bound. These tables cover only those conversations, for the whole year: what was lost and what the gardener blamed. The calendar above is different: it covers all problem conversations, month by month.

Tips gardeners share, compared with CSU Extension

28 tips taken from the year's most discussed conversations, each checked against Colorado State University Extension pages. Tips that differ from CSU come first, then tips CSU does not cover, then tips that match.

What gardeners tell each otherCompared with CSUWhat CSU Extension saysSource
Bindweed roots can reach 40 feet. You will never pull it all, so keep pulling and mulching.WeedsDiffers from CSURoots go 20 feet or more. Hand-pulling does not kill established bindweed, but persistence weakens the roots. Shading it out with cloth or plants can work.CSU page
Japanese beetles can't normally survive here. Let lawns dry out between waterings.Japanese beetlesDiffers from CSUBeetles already breed in many Front Range communities. Letting the top couple of inches of lawn soil dry in July and early August can kill many eggs and young grubs.CSU page
Apply milky spore to the lawn against Japanese beetles.Japanese beetlesDiffers from CSUCSU expects no noticeable control for years and only modest effects, killing a small share of grubs.CSU page
Buy ladybugs and release them.AphidsDiffers from CSUExpect released lady beetles to fly away. Encouraging the ones already in the garden works far better.CSU page
Plant after Mother's Day.FrostDiffers from CSUDenver gardeners use Mother's Day as a guide, and freezes have come as late as June 8. CSU's tomato guide puts Front Range planting in late May, once soil is above 55 F.CSU page
Break up clay with gypsum and plenty of mushroom compost.Soil and compostDiffers from CSUCSU: gypsum does not break up clay, and adding it to Rocky Mountain soils is useless because they are already high in calcium. Routine organic matter is the fix for clay.CSU page
Start tomato seeds 8 to 10 weeks before planting out.Seed startingDiffers from CSUStart tomatoes indoors six to eight weeks before planting. Starting too early usually gives spindly plants.CSU page
Avoid commercial compost made with biosolids because of PFAS.Soil and compostNot covered by CSUPFAS is not mentioned. Only EPA Exceptional Quality Class A biosolids are approved for gardens; products with manure or biosolids are often high in salts.CSU page
Plant clover as a decoy for rabbits.WildlifeNot covered by CSUClover decoys are not mentioned. CSU's advice is wire with holes smaller than a rabbit's head, buried at least 6 inches.CSU page
Put out water for squirrels. They raid tomatoes for moisture.WildlifeNot covered by CSUWater for squirrels is not mentioned. CSU: keeping squirrels out is the best long-term fix; protect produce with mesh cages.CSU page
Never use poison on squirrels.WildlifeNot covered by CSUPoison is not mentioned. CSU: control is difficult, and keeping squirrels out with wire mesh and cages is the best long-term answer.CSU page
Mulch first, then water again.WateringMatches CSUMulch cuts evaporation and can halve irrigation needs. Compost mulch: 1 to 2 inches. The order of mulching and watering is not discussed.CSU page
Pull weed fabric out of raised beds.WeedsMatches CSUCSU: do not put weed fabric under mulch. Wood chips belong between raised beds, not in them.CSU page
Blossom end rot comes from uneven watering. Cal-Mag is rarely needed.TomatoesMatches CSUCalcium deficiency in the fruit, set off by drought stress, waterlogged soil or too much nitrogen. Prevention: even moisture, mulch, soil pH near 6.5. Calcium products are not mentioned.CSU page
Spotted wilt virus: pull the plant, don't compost it, clean pruners with alcohol.TomatoesMatches CSUThe only way to manage it is to remove and destroy affected plants. Cleaning tools is not mentioned.CSU page
Tomatoes won't set fruit in intense heat. Wait it out.HeatMatches CSUBlossoms that open on a day reaching 90 F by 10 a.m. abort. Nights below 55 F also stop pollen from developing.CSU page
Use 30% shade cloth on tomatoes in heat.HeatMatches CSUShading tomatoes helps them keep more blooms. CSU names a 30% shade cloth.CSU page
Manure or compost can carry herbicides that twist tomato leaves.Soil and compostMatches CSUSome hay and pasture herbicides survive manure and compost and twist the leaves of beans, peas, tomatoes and potatoes. A pea-seed pot test checks a batch.CSU page
Hose aphids off with a hard stream of water, then spray soap or neem.AphidsMatches CSUA forceful jet of water can manage aphids on garden plants. Soap kills aphids it fully wets, not those inside curled leaves. Neem is not discussed for aphids.CSU page
Bring in birds and use grasshopper bait.GrasshoppersMatches CSUMany birds feed heavily on grasshoppers. Bait is slow and works only on young grasshoppers; treat in May at lower elevations, early June higher up.CSU page
Hail-shredded plants often bounce back. Give them time.HailMatches CSULeafy vegetables may recover: replant if there is no new growth after a week or so. Root crops with no leaves left will not recover.CSU page
Get a soil test.Soil and compostMatches CSUAn annual soil test is the best measure of the need for compost.CSU page
Water trees, shrubs and lawns during dry winters.Winter wateringMatches CSUWater during long dry spells without snow cover, about once or twice a month, only when air and soil are above 40 F. Detach and drain the hose after use.CSU page
Don't add sand to clay. Use compost or wood chips.Soil and compostMatches CSUAdd organic matter, not sand. For clay, choose fibrous materials such as composted wood chips and straw.CSU page
Mix clover into the lawn instead of replacing the lawn with clover.Lawn and xeriscapeMatches CSUCSU is still researching clover lawns. Clover needs some summer watering and may establish best when planted into existing turfgrass.CSU page
For containers, use big pots and drip on a timer. Terracotta dries out too fast here.WateringMatches CSUChoose a slightly larger container to hold moisture. Unglazed ceramic dries out fastest. Drip suits containers and is easy to manage with a controller.CSU page
Don't replace a lawn with rock or gravel alone.Lawn and xeriscapeMatches CSURock mulch can become a heat sink and stress nearby plants. Use waterwise plants with wood chip mulch.CSU page
Buffalo grass or blue grama lawns use far less water than bluegrass.Lawn and xeriscapeMatches CSUTurf-type buffalograss needs about 50% less water per season than Kentucky bluegrass. Buffalograss and blue grama can stay green for weeks without watering.CSU page

Ideas for your own discussion

Questions this report may help your team ask. They are starting points, not recommendations.

Learning programs

Knowing which months bring frost, heat, weeds or pests, and that new gardeners ask most about soil, watering and weeds, could the same calendar shape what you teach and when?

Draws on: When each problem hurts; New and experienced gardeners
Tomatoes and peppers first

Tomatoes or peppers come up in almost half of all vegetable questions. Would a season-long tomato and pepper series, or matching seed and start offers, meet people where most of their questions are?

Draws on: Which vegetables people ask about
The planting-date gap

Gardeners plant around Mother's Day; CSU's tomato guide points to late May, once soil is above 55 F. Is there a moment in May to explain the difference, before the frost questions peak?

Draws on: Tips gardeners share; When each problem hurts
A Colorado myth list

Gypsum for clay, store-bought ladybugs, milky spore and 40-foot bindweed roots are all repeated as fact. Would a one-page list of local myths and what CSU says help at a counter, a class or in a newsletter?

Draws on: Tips gardeners share, compared with CSU Extension
Where advice comes from

Gardeners mostly learn from each other and rarely name CSU Extension. When CSU material was shared directly, such as its tree list or a question-and-answer session, it usually drew more discussion than a typical conversation. How could reliable local guidance join those conversations?

Draws on: Tips gardeners share
After the sale

About a quarter of loss conversations are about plants put in recently that never took hold. easyDacha sends gardeners step-by-step care tips for each new planting through its first year, timed to Colorado weather. Would giving your customers that plan, through a partnership with easyDacha, help more of what you sell survive?

Draws on: Plants lost or dying
Lawn transition windows

Lawns are the most discussed topic and the largest share of plant losses, and talk of replacing them peaks in March and again in October. Could rebates, workshops and plant offers line up with those two windows?

Draws on: When each problem hurts; What gardeners shop for and plan
Native plants all year

Native plants come up in about one conversation in twelve, in every month of the year, winter included. Is there a reason to promote them only in spring?

Draws on: What gardeners shop for and plan
Shelves and seasonal offers

Seed starting peaks in March, bulbs and garlic in January, mulch and compost in October and November. Could that pattern, and the products gardeners already recommend, guide the front table and the next newsletter?

Draws on: What gardeners shop for and plan; Products gardeners talk about
Sourcing and trust

Gardeners recommend compost but question what is in commercial compost and topsoil: herbicide carryover, PFAS, clay fill. What would help them trust what they buy?

Draws on: Tips gardeners share; Products gardeners talk about
Beyond vegetables

Flowers, trees, lawn alternatives and native plants together take more conversation than food gardening. What do you offer these gardeners?

Draws on: Where gardeners' attention goes
The quiet months

November to February bring only about one conversation in ten, but in those months gardeners talk more than usual about bulbs and garlic, trees and shrubs, houseplants and bringing plants indoors, and about groups and classes. The most discussed winter advice, watering trees and lawns through a dry winter, matches CSU. Could winter be the time for planning workshops and tree clinics, ahead of the March rush?

Draws on: When each problem hurts; What gardeners shop for and plan
A head start on spring

Gardeners are already planning beds and talking about seed starting in January and February, weeks before the first problems show up in March. Would a winter offer or class on seed starting, soil and bed prep reach them while they are still deciding?

Draws on: What gardeners shop for and plan; New and experienced gardeners
Dry seasons

2026 was dry. Everyday watering questions and the rules on when and how much to water were among the most discussed problems. If dry seasons become more common, how would those rows change for the people you serve?
