Nighttime visitors to the allotment

For a long time I could only guess what is happening on the allotment in the night. I assumed there might be a hedgehog as I found faeces but never saw one. Until I got my wildlife cam.
This is a nice little waterproof camera which can be left outside where you want it, to capture images and videos of wildlife. The camera has a motion sensor which activates the camera as soon as something moves in front of it and an infrared beam for nighttime shots. I have programmed my camera to only activate during the night to avoid taking videos of all the birds frequenting my allotment during the day (at one time I had about 50 video clips of various blackbirds in just one day).
So thanks to my wildlife cam I now have a much better idea of all the nighttime visitors on my allotment.

So what did I find? Firstly, I was right, there really is a hedgehog visiting my plot. A nice healthy-looking one, coming nearly every night. The last time I have seen him on the camera was on the 24th of December which was quite a mild night. Apparently hedgehogs do not hibernate deeply but wake up now and again when it is milder to eat something and defecate. I also found out that hedgehogs don`t seem to like eating big slugs as in one video clip I could see quite a large slug which was completely ignored by the hedgehog.

 I made a little film about the hedgehog which you can watch below.

Other nighttime visitors are little wood mice which I am quite fond of now. Often you just see a pair of tiny glowing eyes first, before it becomes apparent that you are looking at a little mouse. They are very skittish, always expecting a predator behind the next bush. And they are right to be careful. In one of the video clips I saw a cat running off with one of my wood mice in its mouth, quite a disturbing sight!

Below you can see a short video featuring the wood mice.

Which brings me to the next visitor, not a popular one with me (but cat lovers might disagree), namely cats! There are all sorts of cats on my plot at nighttime, black ones, brown ones, long-haired ones, fat ones, thin ones, you name it. Sometimes I think the whole neighbourhood cat population finds my plot irresistible. Poor little wood mice. At least the hedgehog does not seem to be bothered, he is well protected in his thorny coat.

A few times I have also had rabbits on my plot, but apart from digging shallow holes here and there they don`t seem to do a lot of damage. Not so on my allotment neighbours plot. He likes to grow parsnips and carrots and always leaves some in the ground to overwinter. I had a look last weekend, and what can I say, there is not much to harvest anymore. All the tops have been completely hollowed out, with tell-tale signs of rabbit poo nearby. It does not take much to name the culprit here.

Other visitors to my plot are wild rats. Some people now probably say: Yuck! Vermin! Kill them all! But I think they are part of the wildlife on the allotment site and have as much right to be there as the hedgehog and the wood mice. There are only a few, they don`t do any damage and they generally keep a low profile (it is very unusual to see them during the day). There is even the added bonus of quicker composting as the rats like to dig tunnels through the compost which helps with aeration and mixing.

Last autumn I found some faeces which looked suspiciously like coming from a fox but so far I did not have one on my camera. I have seen one a few years ago when I was on the allotment very late, the wind was blowing towards me and the fox did not smell me. I kept very still and watched the fox walk past me only about 10 m away, an exhilarating experience. So there are foxes on the allotment site, I just need to get one in front of my camera. A little challenge I set myself this year. Watch this space to see if I am successful.

There is another little video I made with the hedgehog, little wood mice jumping around, the wild rats and a rabbit which can be watched below.

How to grow great celeriac

When I talk to other gardeners or look through gardening forums online I get the impression that many people find it difficult to grow decent-sized celeriac. I have to admit that I never had problems growing celeriac, mine typically weigh up to 800 or 900g at harvest, big enough to use for 2 meals for 2 people. If you struggle growing celeriac in your garden or on your allotment why not try out my way of growing this tasty vegetable?
 
1. Start early
Celeriac needs a long growing season and I always sow the new crop of celeriac when I harvest the last plants from the allotment, which means in a normal year mid-February. I sow the seeds under cover in good seed compost with a sprinkle of vermiculite on top and keep the seeds at about 15-20 C. After germination I wait until the first true leaves appear and then prick the young plants individually into plug trays. I transfer the young plants into 7 cm pots once they are large enough and plant them outside at the beginning of May (later if we have a cold spell).

2. Keep them warm
Celeriac likes it warm and will not appreciate if it is subjected to cold temperatures which will check the growth and might even initiate premature flowering. I keep my celeriac under cover for as long as possible (up to mid-May in colder years) and once they are planted out I protect the young plants with a layer of fleece until about mid-June.

3. Feed and water well
Celeriac needs rich soil which holds moisture well even in dry spells. I always add manure and home-made compost to the bed I have destined for celeriac. It is also important to water well in summer. In dry spells I water every 2-3 days. Once a week I feed the plants with home-made comfrey fertiliser (comfrey leaves fermented in water, 1 part smelly comfrey liquid mixed with 10 part water) which is very effective.

4. Remove outer leaves in late summer and autumn
There is some controversy about this as it is not clear if removing the outer leaves in late summer and autumn really improves the swelling of the celeriac stem (the part we eat) but I always do this and my celeriac always have massive stems (not very scientific, I know!). Maybe in one of the next years, once I have more space, I will set up a little experiment with a proper control (no removal of outer leaves) so I can find out if there really is a difference.

5. Harvest, cook and enjoy
Celeriac is not completely winter-hardy but will sit happily outside through winter if you give it some protection with a double-layer of fleece. I normally harvest the last celeriac in February. They last several weeks in the fridge once harvested. Celeriac has a nice aromatic celery flavour, I use it together with potatoes as mash or in soups and stews.

Frosts and snowdrops: The allotment in January

January is a very quiet month on the allotment, not much is happening but it is a good time to prepare for the new growing season and to get ahead with things before the "madness" of spring starts.
As much as I love spring with all the new growth, seed sowing, buzzing bees and flowers opening everywhere, I also enjoy the down-time now which gives me time to think and plan ahead.

I have mainly been emptying the composters at the beginning of January and spreading the compost onto the flower beds. I have 8 composters now which give me a nice amount of my own compost. I use it mainly for the perennials as it is much easier to spread than the manure and not smothering any plants. The only downside is that I am also spreading annual flower seeds around as the composters don`t get hot enough to kill the seeds. Nigella and Calendula are a bit of a nuisance sometimes and I have to remove most of the seedlings to protect my perennial plants from being overwhelmed. But I always leave a few as I like their cheery flowers.  I was also shifting the manure which went onto the beds destined for growing pumpkins & squashes, potatoes, tomatoes, beans and sweetcorn.

Perennials hardening-off in the cold frame

On milder days I have planted perennial flowers and grasses in the new flower beds. I grew most of the perennials from seed last year and hardened them off in the 2 cold frames I have on the allotment.
The new steppe planting is nearly finished now, one of my favourite areas on the allotment. It will be very exciting to see it develop in the next years. I planted Kniphofia,  Euphorbia epithymoides, Ratibida columnifera, Inula ensifolia, Pulsatilla vulgaris, various Eryngium, Echinacea pallida & purpurea, Phlomis cashmeriana, Tulipa praestans and the grasses Koeleria glauca, Melica ciliata, Bouteloua gracilis, Schizachyrium scoparium and Festuca glauca. I still have to plant Asclepias tuberosa and Geum triflorum. I will cover the area with sand and gravel to mainly keep the slugs away as apparently Asclepias tuberosa and some of the other plants such as Ratibida are very palatable to slugs. It also looks nice.

I have put some bird feeders out last autumn and since then there is a constant stream of birds, mainly blue tits, great tits, long-tailed tits and my allotment robin, filling their bellies with tasty peanuts and nourishing fat. It is a joy to watch them, busily flying back and forth between my feeders and the nearby hedge.

The first crocuses

One of the highlights of January was the appearance of the snowdrops, crocuses, Cyclamen coum and winter aconites. I saw the first crocus flowers on the 12th of January, the earliest I have ever seen them flowering (see also my earlier blog post here). The snowdrops seem to be spreading slowly and some appeared in places I have never planted them. Snowdrop seeds have an attachment called elaiosome containing fats and proteins, which ants find irresistible and carry off down their tunnels to feed to their larvae. This successfully distributes the seeds to new locations which explains my spreading snowdrop population. Cyclamen seed are distributed in the same way.

It always lifts my spirits to see these hardy flowers in the middle of winter, adding a splash of colour to the mainly green, brown and grey colour palette. It is also a sign that spring is not too far away now.
