How do you know it's ready?
It's an exciting time of harvest and I want to guide you with a few ideas of fruits and roots
And judging their best time to pick them like melons and tomatoes. We're going to look at cucumbers
And also some beetroot and some sweet corn and potatoes
So these melons here. Wow
You can see quite nicely the difference between an unripe melon
Which is still green. That's the color. It's been since it formed about three four weeks ago
And a right one and in fact i've been watching this one
First of all, this one went rife about three or four days ago. Then this one two days ago
And that yellowness has all happened today
Compared it was like that this morning and now it's that this afternoon
It's a warm day. It's probably 34 degrees in here
27 degrees outside so that's an indication that you want to be ready to harvest them and you notice they're not
supported by anything
And they only fall down if you leave them on for too long, which means they're really ripe
And hopefully with a sharp knife you can cut like that
and also looking at this you can see the
Cracking around the stalk. That's another sign of readiness as well as the change of color
And more than anything the biggest clue
is this amazing aroma you'd get it as soon as you walk in the greenhouse at the moment, so
We we could just have a quick look at this one and see
What it's like inside and then I I want to show you one or two other melons and how different they are
This will be orange. I hope because it's a charente
And their flesh normally is orange
It's a variety called alvaro
I am just going to taste it. I can't resist it
And I sowed it on the 28th of march
planted in here early may
just before quite cold weather
It's delicious as you'd expect and helped also by
The leaves are still green. Sometimes melons the leaves can go off before the fruit ripen or while they're ripening and that takes away from
the flavor because they're not
photosynthesizing
enough to bring in more sugar
And it's been helped in here by I use some
Red spider mite predator because that can really damage the leaves
Um late june early july. We're now the 21st of july actually. So, you know, this is actually the greenest i've had so
uh, check out the link for
Buying those spider mites
In the video description. This is a different variety called emia and again, you can see it's cracking
and a lovely aroma as well, so
I really feel when you see that
It's it's risky to leave it too much longer. I want to keep the stalks actually
I will be selling these to the three horseshoes pub and
They will keep much better if you manage to keep the stalk on, you know, otherwise they will fall on the ground
Well, you know place it gently on the ground collect it later
um
And then here we have a different melon, which is ogan
and
It has a green flesh and you can see it's quite green as it grows, but this one is just starting to yellow
again
These go quite slowly though
That could be four or five days before it's really ripe and you can see the next stage there
I've let quite a few go on the ground as well
And that will go bright yellow probably in about two days and that's that shows it's a good time to eat it
harvest and eat it
while tomatoes
It's a bit different according to what variety they are
And you can see all different colors here. This is a yellow tomato
That's definitely ready to harvest and with beef tomatoes. They don't always snap off easily. Let's just see if that one does
Uh, no, so what I want to do is keep the stalk on
the calyx
so I use a knife to cut the truss and that's
that could
This could carry on ripening off the plant
It's it's actually ready now, but you can harvest
tomatoes when they're
Breaking stage it's called. Um
I'm, not seeing any here. Actually. There's one just there
And this is a sort of yellow orange oxide, which is just starting to ripen
You could harvest that now and it will ripen off the plant
The loss of flavor from doing that is actually quite small
and whereas with cherry tomatoes
They definitely benefit like the sun gold from leaving them on the plant until they're fully colored so these are ready now
Aren't they gorgeous?
um
And these I was looking at just before we filmed and this one actually fell off when I touched it
So that was an indication of ripeness and how these ones do snap off like that
And also this cracking around here
It's nothing to worry about it. It doesn't bother me anyway, and they're still really good to eat
This is another sign of ripeness
And i've got a shrug somewhere which i'm going to add these two
And then we're going to go outside and we'll look at watermelon
So in the polytunnel, you can see wow, there's a lot of tomatoes suddenly ripening. This has all happened very recently
and
it's an indication of how
Sometimes you're waiting and waiting and then before you know, you have more than you expected
Here that is a watermelon which i've been
Noticing only for a few days because watermelons grow
For quite a long time just as plants and no fruit and then suddenly they make fruits like this
And one indication of readiness is just tapping it
actually, that does sound a bit hollow, but
you're hoping for a
Real hollow sound. Um, I would say we're not quite there, but actually having said that
This little tendril now i'm not seeing this is the tendril
It wants to be more brown than green so that's an indication for me anyway that i'm not going to pick this one yet
Watermelons are funny things because they kind of have a mind of their own about when they've got a fruit and
They don't really have that obvious sign of ripeness like melons do
Like these melons here
Fantastic crop of alvaro again on just one plant, but you can see how they're all green
and the polytunnel is just not quite so warm as the greenhouse and that's
It's nice because it gives me a succession
Uh more emia here still all green and the ogan. So that's fine. No rush on there
while the cucumber
They've been cropping for well over a month now
and
You know, you've you've got flexibility
That's looking good, um
You could leave that for another day or two or just get bigger
But actually I find it better to pick them at about that stage because that takes the strain off the plant. That's another factor
If the plant is being asked to swell this cucumber
It doesn't have so much energy to develop new ones as we go up the stem
so
always have that in mind as well with
Tomatoes too, you know if you leave them on the plant too long
And they're still trying to make a lot of new ones at this time of year
and
we could
Just quickly have a look at outdoor cucumbers just for comparison
Because that's cordon cucumbers
Which are the big ones we grow in england particularly and many people are used to buying cucumbers like that and they're growing undercover
vertically, whereas these are
more gardening style ridge cucumbers
And there's just two plants here
of a variety called la diva
and
Are these ready? Well, I would say yes because not that they're big
But they're these plants are still young. They haven't grown a lot. These these cucumbers are starting to swell around the shoulder
And you see it's getting fat there. So I would cut that one and actually I would cut this one as well
And another sign is if you see some skin degradation like here
And that's not a problem because with cucumbers
you can easily
Take off the skins
With a vegetable slicer. I do that. I like it because I i'm not a great fan of cucumber skins
I really love the the juicy flesh
I put a bit of salt with them and leave it for a few hours and they really sweetened doing that
So all of that is a great harvest from these two little plants which have
Been in the ground for less time than polytunnel not quite so warm, but now it's really warmed up out here
They're going to give a lot more harvest yet
And now we'll have a look at sweet corn
So with sweet corn
The tassels need to be changing color
And that that's one clue. There's many clues
And
If you happen to pick one, that's not quite ready as in doesn't have a lot of beautiful yellow kernels on you can still eat it
It's still edible. It just won't be maybe quite so nice
And more like a mini corn you could eat the center of the cob as well
But as well as the hairs going a bit brown
These are not as brown as I was expecting them to be actually and they've ripened really fast
You're you're feeling for a bit of swelling and decent sort of fatness
on these
Cobs and actually a lot of them are looking ready. There's
A big harvest here anytime now i'm going to pick this one
So i'm just snapping it off like that
and i'm also looking below it at
Is there a second cob and in this case?
not really that's
Kind of a cob but it's not and so i'm actually going to take that plant out now because
It's taking moisture from the other plants. So I remove the plants
As soon as i've harvested from them everything they have
And let's have a look
Oh, wow. Yeah, look at that. What a beautiful corn
And you can see a really good set
And that is helped by having them
In a block like this. It's not vital. I've grown nice corn in a line
it can be done but you don't get quite such a full set of kernels because
What happens here is you've got the male pollen dropping off this top bit
And that was probably about a month ago
and
You need a male
Piece of pollen to fall on each of these hairs which go down that each one is connected to the the sweet corn
so
Wow, I can't resist just peeling that
Let's see if I can snap off that. No, I can't
But yeah
This also is a super sweet variety
Which means you know, it's not only a question of
When to harvest it, but when to eat it and these super sweet varieties
Stay sweet for much longer than the old-fashioned open pollinated ones
which are still good to grow for sure, but those are the ones that you need to
Eat as quickly as you can after picking them because the sugars
reduce whereas this one
they maintain
And just on the other side of the sweet corn we have potatoes
These are desire
Which is a main crop
So what does that mean main crop harvest later?
You have categories of earliness with potatoes first earlies usually in early to mid-june second earlies early july
Now we're in late july usually in august actually
Main crop if they haven't got potato black
So this is no dig and
I'm harvesting them just by pulling get my hand around all of the stems
And pull gently upwards
and you can see there's the harvest
and
It's not bad
I'm proud of that, but it it would have been bigger if we'd had some more rain
We haven't watered these very much. You can see how dry the soil is. It's actually quite dusty
Uh, it's also quite close to a sunflower
And some people say sunflowers are allelopathic which means they don't like other plants or vice versa
But actually it's not that at all. It's just that they take a lot of moisture to grow themselves, but I love sunflowers. So
i'm very happy to
Put up with a slightly smaller potato harvest
And it's good to compost all of this
the bits you don't eat
Now you can see the potato seed there. So that's the seed that we planted in
April in this case
And that's good to compost as well. So all of that can go on the compost heap
And i'm going to put this in my truck and then we're going to have a look at beetroot
two more things about the potatoes is one that they
You can see they're still quite green and that's an indication. They're more growing to be had especially if we can water them
And they are quite close. So we put them in just 18 inches 45 centimeters apart
And for potatoes that is quite close especially for main crop
Uh, it's a bit the same here actually with beetroot. So
These beetroot are spaced
multi-zone clumps at not much more than a foot or 30 centimeters apart and they're also quite close to the celeriac
There so this is really intensive cropping in a small space and already this year we've had carrots there
There are only a couple of kilos of carrots from a March sowing
They harvested in early june and these little seedling multi-zone clumps went in the ground on the 8th of june
Which is just 43 days ago. And so in not much more than seven weeks. They've done all that
and
it slightly caught me by surprise actually because
What i'm a bit concerned about now is with
As beetroot get bigger they're taking more moisture and nutrients from around them and they will somewhat compromise the growth of the celeriac
So what you can do with multi-zone is it's not so much. When are they ready?
It's when are you ready to eat them?
And if you want some you can just do that twist out a bigger one from a clump
And again, I could do the same there
You can see how easily they come out. This is kyojo, which has the beautiful white rings in really sweet beetroot
And here we have flaming barrel, which is more a golden yellow beetroot
Again, i'll twist out the bigger one
like that and then
You can see how they are also quite close to dwarf french beans here
So, you know juggling a lot of a small space here to get more harvest
Which is very doable, but you need to be on it with harvesting
And so there's a lot to eat all the time. It's a really nice
Problem to have
And behind here there's another vegetable which has quite a variable date of harvest and that's celery
So as long as you keep it watered
today, uh, we didn't get around to watering the celery, but normally do
and
It's it's ready when you want it. You know, this would grow bigger if you can keep watering
Uh, even though the spacing is quite close. You can see it's not much more than nine inches 22 centimeters there
There's a lot of celery here variety called tango
sewn in
Early april planted early middle of may roughly
And I cut it just below the stalk
There are many ways of doing this, you know, you could
Cut it like that and you'll get some regrowth
um, I don't actually want that i'm happy to
let the celery
um
Just have one harvest like that
All of that is edible and you can use the leaves stalks everything celery is a really good value vegetable from that point of view
And there's just one more thing I want to show you in this video because today we were
Harvesting the red onions finally
red onions tend to come a little bit later than
yellow onions
my yellow onions actually were the
Rose de roscoff, which you just got one clump there
And and that's these ones
And you can see how beautiful rose or pink color they have on the bulb
You can also see how the tops are much more
dry compared to the
Red onions red barren here growing from seed multi-zone clumps again
No bolters growing from seed is really reliable
and
They're decent sized bulbs, but look how green the leaves still are so with onions
You're not always looking for the leaves to go yellow
But what was happening before we pulled them today
Probably about three quarters of the stalks of stems had fallen already
and we put it like this to
Make sure all the stems so they've been pushed down to really
Make sure there's a tight neck there
So you don't want a fat neck for them to store well when you come to just cut cut the yellow top off
So these will stay here for about a week or 10 days
They're fine in the sun, but it's good to have them pointing down if you can
And they'll be slowly ripening
And then here to finish there's just a very different kind of onion
Which is long red florence or tropia longer
And it's just beautiful. It's not a big one for storing beyond about
November december, but it's it's such a sweet and tasty onion that I love to grow it
And these also were multi-sown and yeah, there weren't many plants there and got all of these onions, so
Check out my other videos on multi-sowing and on these other things
It's no dig that really makes life easy because onions can be quite difficult to weed otherwise
And we are going to publish
Quite soon in another video about how to grow all these beautiful vegetables in more detail
