Every year, without fill, I plant my tomatoes too close together and then quit trying to pinch out suckers, which then leads to a jungles of tangles tomato vines. I'll never learn😜

Leaving my pots of seedlings within reach of my 2 year old!!!!!!!

[surbie100]

Buying/otherwise acquiring too many new varieties of seeds that I cannot stop myself from sowing.
Not potting on plants in time.
Planting things too close so I can cram more in.
Believing I can dig much more in a day than I actually can and basing all my plans for plot success on this misconception.
Believing you can never have too many chillies/squashes/tomatoes/new things.

Collecting seeds
Sowing too early
Sowing too late
Sowing too much
Sowing whats left in the pack as I think the seeds are naff as the first couple of sowings done nothing
Not potting on early enough
Keeping spare plants just incase (that are still lurking almost/completely dead 6-8 months later)
Thinking my greenhouse is bigger than it is
Thinking I will actually eat it all if I grow it
Planting too close
Not watering enough
Are you sure you're not me? 😄
Not feeding enough
Not securing netting at every possible miniscule point

And yet they still grow

Not labelling pots properly 

that is one of  my failings also.

[Baldy]

Labelling - I'm a bit better but still not great.
Too many plants in too little space
Labelling
Weeding - not done regularly enough leads to half day of weeding rather than a bit of weeding and then some more entertaining stuff getting done
Labelling
Pip pip,

 :lol:I do so many of the things mentioned above -

Not potting on soon enough so plants are pot bound
Planting too close
Not picking in time so things go over
Cropping and then not eating in time - devastating to see my own produce go to waste.  I don't do this too often, but I do do it 
Not going up to water my allotment enough
Growing on to many plants

what a relief I am not alone

[Mrs Bee]

I feel so much better reading all this, 'cos it is all of the above.

Plus, letting OH plant too many spuds and running out of space for other stuff, which then results in a mad dash to clear more of the new plot and playing catch up to stick in plants that were pot bound and desperate to get into the ground.

[cadalot]

I can identify with so many already said !

[mikem]

Going on holiday and expecting the plot to still be weed free when I get home.

Thinking I can still work as hard and as long as I did when I was in my 20s!

Not sitting down enough and enjoying the allotment.

I feel so much better now that I realise that it's not just me!  Despite writing myself notes for the following year, I STILL commit the same sins over and over again.  I am getting better at labelling stuff, and not thinking that I'll remember what variety it is, and I don't try to wedge quite so much stuff into the plot, so I can, at last, manage to get between the various crops, so I am improving a bit. Other than that, I'm still guilty of any and all of the mistakes that everyone else makes.

So agree with the last sentiment.  Was thinking how retirement is supposed to mean more relaxation, can't work out what's gone wrong!  Think it's the old adage of work expanding to fit time available...

As well as the above,
Not staking things soon enough.
Sometimes planting things too far apart in my raised beds.
Not re-sowing more seeds for later crops.

[JayG]

Sitting back with a small sigh of relief to admire my handiwork around mid June having finally got all the 'summer stuff' planted out, thereby forgetting that salad crops need re-sowing to keep supplies going into autumn.

Every year, mindful of the fact that Florence Fennel is best sown later to avoid the worst of the heat, I forget until it's actually too late, so still get nothing edible. 

Will get the seed packets out again today (maybe!  )

[Nikkithefoot]

So nice to not be alone in this!!!

Mind you the weather really doesn't help does it? There is always next year
