Good morning everyone, my name is Emma and in this video I'm going to be
sharing all the seeds I'm going to be sowing for my allotment plot in the month of March.
So if you haven't heard of me before, my name is Emma like I just said, I vlog all about
my allotment plot here in South London. I also put up a home diary on a Sunday as well
sharing what I'm cooking or what I'm harvesting for my allotment plot and some of my home
garden in London as well. So if this sounds like something that interests you, please
hit the subscribe button, follow me along this year and we can all help each other out.
So March is really the time when I do start most of my sowing for my allotment plot. However,
we have to remember that spring doesn't technically start until the 22nd of March and we are still
in sort of the end of winter at the beginning of March. So even though it might feel like
spring, it sounds like spring, you might get some sunny days. For seeds, it is still winter
so we have to be quite careful of what we sow. However, as we do go through March, more
and more stuff can kind of be planted directly outside or sown directly outside and that
is my favourite thing to do. When you have an allotment plot, space is definitely a slight
issue. I'm lucky enough to have this greenhouse here but before then, I would sow most of
my stuff directly just because I didn't have the room to start it in pots and modules.
And starting it directly is so easy as well. You just make a drill in the ground, sow in
your seeds, away they go. So I've got a mix here of things that I'm going to be sowing
in modules in my greenhouse and also directly outside. And I'll talk you through them as
we go. First thing to say, if you are growing tomatoes, now is a good month to start them,
to start your seeds. I actually started my seeds last month in February on my window
sill at home and if you want to know what tomato varieties I'm growing, you can go back
to Seeds and Sowing in February and I will link the video to that so you can go and see
what tomatoes I'm growing. But tomatoes, you can start in March, it's all good. Also just
to reiterate as well, these are seeds that I'm sowing for my allotment plot. This is
not every single seed that you can grow in the month of March. So now is the month when
I'm going to be starting some of the warmer loving crops and two in particular that I'm
starting are cucumbers and courgettes. So I'm growing quite a few varieties of courgette
this year but the variety I'm most excited about because I've never grown it before is
Banana Song F1 which, as you probably guessed by the name, is like a yellow courgette. I
think I've attempted these a few times, maybe got one courgette from them, but I'm going
to have quite a big variety of different courgettes this year because I do love them, I use them
a lot in my cooking and they are a really great seed to start in March. So I'm going
to start these in my polycarbonate greenhouse in pots. I'm also going to start my cucumber
and the cucumbers I've got this year are Mini Munch F1. My cucumbers are going to go into
my polycarbonate greenhouse because they really do need a lot of warmth. I have tried cucumbers
outside before, even when we've had a really warm summer, and they just seem to struggle
where I am. So planting them under here I think is just a good idea. In terms of flowers,
I've got cornflowers, I didn't bring them with me today unfortunately, but they are
the standard kind of purpley, pinky cornflowers that you get. The thing with cornflowers is
they grow so easily and they grow really tall and the bees and butterflies love them, they
are always covered in pollinators. So with my cornflowers I just like to cover a whole
bed in them and have them just grow up in a great big bunch. That way we attract as
many pollinators in and they look absolutely beautiful. So I will be growing cornflowers
this year. Right, sunflowers, I always start my sunflowers in March, I absolutely love
having sunflowers, and I also succession sow them, and I'm going to be doing that this
year. Which basically means that you start some, they grow on, and then a few weeks later
you start some more, and then when the first ones finish you've got more to plant out,
so you kind of get like a succession of the crop, and you don't run out basically. And
you can do that with lots of crops. The three varieties of sunflowers I'm growing this year
are these ones, which are gigantic ones, these are the really big sunflowers that you can
have a great competition growing as big as you can. Love those. Then I've got the helianthus
sunflowers, which are just a really gorgeous variety, kind of a bit pastel shady, just
really gorgeous. So I'm going to grow these ones, and then we have got the helianthus
giant single as well. Now I grew these ones last year next to my archway, and they were
just absolutely stunning. A really gorgeous sunflower with lots of very flimsy delicate
petals as well, so this is a really great one to grow. They also grew really big, it
says they can get between 6 and 10 foot, and I think mine got to about 7 foot, which were
amazing. So we're going to grow these as well. And I have, I'm afraid to say, already started
some sunflowers last month, which was the last week of February. That's probably a bit
too early, but I have high hopes for them. I have high hopes for my sunflowers. I have
also started cosmos, but you can still start cosmos in March. These are my cosmos so far,
that's where we are with them. So they're getting nice and big, looking very, very good
and healthy. These are kind of your bog standard cosmos, and each of these plants will get
very big and bushy, so I need to pop these on. These are a great thing to grow in your
allotment plot, attract lots of bees and butterflies. Right, down here I have got some cabbage pack
choy. This is a really great choice for an allotment plot. They grow really well at mine,
pack choy. You get hundreds of seeds in this pack. This is by Premier Seeds Direct. Whack
these out straight directly, I think, so I think I'll be doing these about mid-March.
I'll whack some of these out directly into the ground. I'll be starting my brussel sprouts
today. These need a very long growing season, so you have to start them in March or April.
I would say March is the best time to start them, and you'll be harvesting in sort of
November to January, so that's how long they take to develop. Dark Mar 21, very sweet and
tasty. I have grown them before, and this is from Kitchen Garden magazine, King Seeds.
There we go. If you buy Kitchen Garden magazine, you often get quite a lot of seeds with their
magazine, which is fantastic. I'm going to start some celery this month. I've got the
Victoria F1. I will probably sow these directly as well, and then I've got some more carrot
seeds here. Carrot Amsterdam 2. I am growing quite a few varieties of carrot this year
because carrots are something I struggle with, so I'm just going to whack in as many varieties
as I can in the hope that one of them works. I've already planted out some nance, and we're
going to go and see if they have germinated yet. I have covered them over, don't panic.
I have some all-year-round cauliflower here, which is growing really well. You can start
that this month from a seed if you would like to. I'm growing them in pots, and then I'm
going to plant them out when they're bigger, just to try and deter the slugs and snails
so they don't eat them all in one go. I've got some leeks here, and the reason why I've
sown my leeks into modules here instead of directly is just because they sort of disappear
in my allotment plot. I put the seeds in and I never see them again, so I thought this
year I would try them in modules first, and then see if I can get them a bit bigger before
I plant them out. And we've got some Cavlonero kale growing really well, so this will need
potting on very soon. As soon as we see true leaves, these are the seed leaves at the moment,
so they're not quite ready to pot on, but as soon as we see some more leaves appearing,
we can prick them out and pot them on. Right, this is where I've started my carrots. I've
got some nance growing here. Now, nance are a really great beginner variety of carrot,
so I'm really going back to basics of my carrots, because like I said before, I really struggle
with them. They just don't want to grow for me. I've got them in this container, and then
I've got a glass panel over to try and keep them warm, because it is still a little bit
early for carrots. I doubt they've germinated, but let's have a look. I expect it's far too
early to see any carrot germination here, and I am right. Actually, I think that actually
might be a carrot there. That actually might be the first carrot that's germinated. Well
done, mate. Yeah, that does look like a carrot seedling, doesn't it? Fantastic. The thing
with carrot seeds is they are so small that they dry out really quickly, so you have to
keep them really well watered and moist all the time, because they dry out super fast.
By keeping them covered like this, you're keeping all the moisture in as well, which
gives you more chance of germination. I also have them in quite a tall container there,
which is full of sandy soil, which is really good for them to grow through, so they don't
hit any rocks and split. Also, it keeps them away from the pesky carrot fly. Carrot fly
will attack your carrots, but it can't fly very high. It can fly about a foot off the
ground. Hopefully, by keeping my carrots higher off the ground, I'll deter all the carrot
fly, which will be excellent. This is how I'm growing my carrots this year.
Have you ever heard of a seed snail before? I have never heard of it until the other day
when somebody shared an Instagram rule with me, showing me how someone's making a seed
snail to sow their seeds in. It's a really clever way of sowing a lot of seeds in a small
space. The way you do it is to wrap them all up. I'm going to try it today with some
peas. These are snap peas, which are a warmer-loving pea. March is a great time to sow them inside
a greenhouse or inside, because they do need warmth, these peas. These are the kind of
peas that you can eat the whole thing. I absolutely love snap peas. I thought I would grow them
in a seed snail to try and save some space. Let's give it a go.
Here's our strip, which we've just cut from an old compost bag. What we'll do is put some
compost on here. What we're going to do is roll it up like a snail. That is our seed
snail. It's just basically a rolled-up compost bag with some compost inside. I've popped
it into a pot. I've left the bottom of it open so we can water it a little bit better
and it doesn't collect water at the bottom. This will be able to drain. I'm going to sow
our peas into this. There they all are, sitting in our little seed snail. The peas are actually
growing quite far away from each other, even though they're in close proximity. Does that
make sense? I think the idea is when they have grown, we can unroll it and then we don't
disturb the roots as well, so it becomes a bit of a root trainer too. Let's fill these
in and give them a water. Interesting. Thank you to everyone who recommended I try this.
I will let you know how they go. I'll just pop them up there. Hopefully, we'll get some
really good germination out of that. I'm also going to start my brussel sprouts today. I'm
just going to start them in a module like this, which is really just all I have at the
moment. I tend to just reuse whatever plastic containers I have over and over again. Brussel
sprouts, Dark Mar 21. I expect there'll be a bazillion seeds in here. Yes, there are.
Try to sow thinly because it's always easier to sow thinly if you can, but when the seeds
are that small, it can be quite tricky. Always pull seeds into your hand. Don't try and tip
them straight from the packet. It's so much harder to control, so much easier to pull
them into your hand. Take a little pinch and then just scatter like this. If you have
taken too many, like I have, when you pour them into the seed packet again, do it over
the top of where you've sown, so if you lose any, they have a chance of germinating and
they're not just going to be wasted. Just pour them in like that. There we go. I probably
lost a few there. We'll just cover them over with a little bit of compost and then we'll
give them a pat down. We're giving them a pat because they need to have contact with
the compost in order to germinate. By patting it down and making sure the seeds, firstly
they don't fly away anywhere and they're trapped where they are. Trapped, I don't know a better
word than trapped. Sounds a bit mean, doesn't it? But also to make sure that they've got
good contact with the soil so that they will give me good germination. We will have to
prick these out at a later date and that will be a fun video because I've way over sown.
So look forward to that. There we go, there's our brussels. So we'll give them a little
water, pop them on my shelf.
And the other thing that will be going out in March are of course my potatoes which have
been chitting away at home. So I've got an early variety and a second early variety and
they will both be going out in the month of March. So my earlies will go out first
and then my second earlies will probably go out a couple of weeks after that. Anyway,
if you want to see me planting out my potatoes, do follow me on YouTube and subscribe to my
channel and there will be a video coming up very soon with me showing you lots more seeds
I'll be sowing and obviously my potatoes as well. I hope you found this video helpful.
If you have do subscribe. I'm going to be sowing more seeds over the next few weeks.
As we go more into March and spring really does start to bloom, it's going to be very
exciting. So hopefully I'll see you again soon. Thank you so much for watching. See
you next time. Bye.
