Feel Free to deal !
Starting plants from seminal fluid is one of my favorite contribution of gardening . There ’s something so rewarding about watching tiny sprouts come forth and develop into unattackable , goodish plants . But I ’ll let in , it has n’t always gone swimmingly !
Over the years , I ’ve made my fair part of ejaculate - part mistake , and I know how frustrating it can be when things do n’t go as project . If you ’ve shinny with germ starting , you ’re not alone . get ’s review some of gardeners ’ most common error and how to avoid them .

Common Seed-Starting Mistakes
Starting Seeds Too Early
It ’s passing tempting to set about seeds as soon as the first seed catalogue arrives , but set about too early can backfire . Many seedlings acquire promptly and become weak or long-legged if they stay indoors too long . Without enough light and space , they struggle to flourish .
central takeaway : Check your last frost date and count back to define the best time to start seeds .
Yes , your last frost date ismore importantthan the USDA Zone you are growing in . I explain it in contingent .
What USDA Zones Tell You & What They Don’t
Starting Seeds Too Late
On the other hand , hold back too foresightful to start seeds can mean your plants do n’t have enough time to mature before the grow season ends . Some plants , like tomatoes and peppers , need a long growing flow . Be certain to plan out front and start come at theright timefor your climate .
Not Reading Seed Packets (another big seed-starting mistake)
Seed mail boat contain a riches of selective information , yet many gardener overlook them . Important details like sprouting time , planting depth , and light requirement are all printed on the packet . Taking a second to register it can save you a sight of guesswork and letdown .
How to Read Seed Packets
Using Old or Poor-Quality Seeds
Seeds do n’t last forever ! While some remain executable for years , others ( like onion plant and parsley ) lose viability promptly . If using older seeds , do a germination test by placing a few in a damp newspaper towel or coffee filter , let fix a few days and see how many sprout before planting a whole tray .
Using the Wrong Soil
Not all land is create adequate ! Garden dirt is too sonorous for seed starting and can have poor drainage or disease issues . or else , use a light , well - draining potting mix or seed - start premix designed specifically for seedlings . This will provide the right texture and nutrients for solid emergence .
I do not use seed - starting mix as it is unnecessary and many times more expensive . Many cum - starting mixes useable are ugly and do n’t lick at all .
Potting Soil vs Seed Starting Mix – An Experiment
Using Dirty Containers
recycle seminal fluid trays and pots is a cracking way to save money , but neglect to scavenge them can introduce disease and pests that harm young flora . Wash and disinfect container with a diluted bleach resolution ( 1 part whitener to 9 parts H2O ) before planting .
I have found that good honest-to-god soap and red-hot water often work just as well . After scrubbing , rinse off well and let dry .
Planting at the Wrong Depth
Each cum has an idealistic planting depth , and burying them too deep or leaving them too shallow can impact sprouting . A good formula of quarter round is to plant seeds at a depth about twice their size . Again , check the seed bundle for specific direction !
Not Labeling Seed Trays – Big Seed Starting Mistake for Me!
It ’s easy to assume you ’ll recollect what you planted where — but once those seedling sprout , many see surprisingly standardised ! Labeling your seed trays or sess prevents mix - ups and aid you traverse germination progression .
This is one come - go mistake I have made many time and I always kick myself . There are many ways to make your own labels . cut funnies from sour cream or bungalow tall mallow tubs . you may do the same with empty plastic Milk River jugs . Or launder and reuse the tags you get in plants you buy from the garden center .
Ignoring Light Requirements
Light Within is one of the most important factors for salubrious seedlings . Many seeds command light source to germinate , and most seedlings require bright , direct lighter for unassailable growth . A sunny windowsill is seldom enough — weigh using grow lights and keeping them just a few inches above your plant for the good results .
Though if you wish to start in a windowsill it is potential . verify to not begin your semen until after the Spring equinox . This cover the day distance is enough for the seedlings to grow strong .
Ignoring Temperature Requirements
Temperature plays a handsome part in sprouting . Some seed , like peppers and tomatoes , take tender filth ( 70 - 80 ° F ) to spud quickly , while cool - season crop like lettuce prefer cooler shape . A rut mat can aid maintain consistent affectionateness for high temperature - loving plants .
Starting plants like tomatoes too early can do more damage than full . While it ’s tempting to get a head start , other planting often lead to unnecessary stress for the plant . A stressed tomato seedling is weak , give it more vulnerable to pests and diseases , which can ultimately conduct to disappointing results .
Overwatering – (One of the Biggest Seed-Starting Mistakes)
Too much water can lead to damping off — a fungal disease that kills young seedlings . Overwatering can also suffocate beginning and encourage mold . Keep the soil moist but not soggy . If in doubt , lease the top of the soil teetotal slenderly before watering again .
I wish to usea wet meterif I am not indisputable , but usually lift the corporation to experience its weighting is sufficient to permit me know if it needs watering .
Underwatering
On the flip side , allow seedlings dry out too much can promptly lead to their demise . Small seed tray dry out out faster than you might require , so hold moisture levels on a regular basis .
Many use a humidity dome to help retain moisture during sprouting . I do sometimes but not always and it is n’t absolutely necessary .
If you use the cork granule or vermiculite as a topper when semen starting they will help hold back moisture . The downside of using a humidness covered stadium is it can encourage fungus growth that can kill your seedlings .
Overcrowding
It ’s easy to sow too many seeds in one container , but overcrowding leads to weak , lank plants contend for nutrients , visible light , and quad . If you found multiple seminal fluid in a tray , be inclined to thin them out orpot them up as soon as possible .
Not Thinning
Speaking of cutting — many gardener skip this footstep , but it ’s essential ! If you have multiple seedling in one cell or pot , bump off the weak ones ensures the strongest plant thrive . Use scissors to snip the extra at soil level rather than pulling them out to avoid interrupt roots .
Well , I have never had a problem with pot up the extras or disturbing the root of most plant . Most plant do n’t mind being potted up when very small . When I lived in the valley there were several grow facilities near me ( they set out industrial plant that were ship to nurseries and garden centers ) and begin seeds in trays was distinctive ( saved space ) .
When the plants got their second set of folio , also live as the dependable leaves , they were then pricked out of the tray and potted into individual cells of 6 - pack container or 4 inch jackpot .
Thin Seedlings Without Cutting them
The plants you want to be careful of are ones like courgette , cucumber vine etc that really hate having their root disturbed . Even zinnias are in that list and is why I attempt to channelise sow them if at all potential .
But you find zinnias and the others in garden centers in 4 - inch pot to be graft all the time so it is potential if not the right way to plant those .
Failing to Provide Air Circulation
dead air around seedlings can conduct to stamp growth and fungal disease like damping off . A small fan placed near seedlings ( set on low ) avail strengthen stems and prevents disease .
The ruffling of the light breeze creates an enzyme action in the plants , hold them grow sturdier and toughening them up .
Not Fertilizing at the Right Time
come - starting mix are often nutrient - costless , so seedlings will need eating once they develop their first set of true leaves . A diluted fluent fertilizer ( like Pisces the Fishes emulsion ) every calendar week can encourage strong outgrowth .
I preferEcoOrganic fertilizer , it is created from food for thought waste for a better balance of nutrients .
I do n’t use source starting mix and I avoid potting soils with semisynthetic plant food added to them but I still will originate feeding them with the diluted EcoOrganic fertilizers after the first or second true farewell seem .
Transplanting Too Soon (or Too Late)
Timing matter when moving seedling to larger pots or into the garden . Transplanting too shortly can damage frail etymon , while hold off too long can go to root - bind flora that struggle to establish . A good rule is to transplant when seedlings have at least two sets of dependable leaves .
Then when it is time to transfer out into the garden you need to verify the weather condition and temperatures have stabilized . Some plants will de-escalate if stressed out with soil and air temperatures below what they require when first starting out . This makes them more susceptible to pest and disease attack .
Too tardily and the plants can become radical - bind in their flock , too leggy and stressed . But it is effective to be a little bit late than much too early !
Not Hardening Off
One of the biggest mistake gardeners make is skipping the hardening - off process . If seedlings are move from a master indoor environment directly to the garden , they can suffer from graft shock .
Instead , gradually introduce them to outside precondition over a week or two by setting them alfresco for increase periods each daylight . work them in at night is peculiarly important if the temperatures are dip too far below 50 degrees .
This step is crucial and is what pretend many give up . It can be a lot of work , especially if you have started a lot of come .
That is why so many folks loveWinter inseminate , this measure is done for you .
Winter Sowing – Lazy Seed Starting!
Giving Up Too Soon
Seed start takes practice ! If things do n’t go perfectly the first time , do n’t get discourage . Learn from mistakes , adjust your approach , and try out again . Gardening is all about experiment and growth !
One more that I just think of … not setting out the mucilaginous maw immediately . Fungus gnats are in all potting dirt and will think of and emerge . place out the steamy traps help to keep them under control .
you may also habituate a neem fossil oil mixture drench or pasteurize the soil . Fungus gnat larvae feast on seedling root which weakens them .

My Final Thoughts
Starting seeds successfully takes a little forbearance and provision , but avoiding these common mistakes will give your works the good start possible . With the proper timing , dirt , twinkle , piddle , and care , you ’ll soon be growing solid , healthy seedlings ready to flourish in your garden !
