2021 Week 4 - My Perennial Project

We'll start with the weather.

It's been a week of fluctuating conditions, beginning with snow and early morning temperatures down to 5 below. But this was followed by a warm and very wet weather system. A couple of nights of heavy rain have seen water levels rise back to annoying levels. The seasonal lake and various ponds have reappeared and it is pretty squelchy underfoot. 

This was my week to be in school rather than teaching from home, so combined with the weather I have had limited opportunities to make significant headway on the smallholding.

Seed sowing steps up
My growing year has stepped up a notch with a gradual trickle of seed sowing. I've pushed everything a little earlier this year and purchased an extra heat mat to help persuade the seeds into germination and keep the tender young plants warm and snug. 

Some of my onions have germinated very well. As they germinate they come off the heat mat to give room for others. They just move to a different shelf on the staging which is currently in a warm spare bedroom. As soon as things warm up a little most of this will move into the conservatory which offers much improved light, but for the moment it's a bit cool in there and damping off of seedlings might be a problem.

All my aubergines have germinated. These need a long season to produce ripe fruit as I grow them outside. Of all my crops these are the most susceptible to red spider mite when grown in the polytunnel and I don't want to risk giving it a foothold back in.

I've started off my indoor tomatoes too, ten different varieties. I'll concentrate on these in a future post.

given up the ghost.

On a more decorative front, some of the seeds I collected from a gorgeous lupin plant have germinated strongly. Hopefully I can look after them and raise them into perennial splashes of colour around the smallholding.

Potatoes
As we move towards February, potatoes loom on the horizon. It won't be long till I pick up my order of seed potatoes for the year and set them to chit. Because of lockdown I saved some of each variety from last year just in case there was a problem with supplies this year. I put them in a spare fridge which seems to have held them quite well. This is just an emergency measure as it's best to start with fresh stock each year.

I have however planted the Arran Pilots which I saved through. These early potatoes have gone into a polytunnel bed with a heavy compost mulch and should give me new potatoes way ahead of the outdoor plants.

Perennial Hope

The week's main excitement has been a steady stream of deliveries of growing supplies. Thank goodness for the internet during lockdown. and this year is seeing a flood of experimental new crops - the product of too much time on my hands during lockdown. The idea of trying a few trendy perennial crops such as oca and Caucasian spinach has rapidly expanded into developing a major new area of the garden. 

I'm no artist, but this sketched plan opens a whole new can of worms

So here are some of the crops which will be in this area:

Fruit and nut trees already present - apples, pears, plum, almond, hazels, sweet chestnut, mulberry, fig. Also small-leaved limes which can be used for fresh leaves and tilia tea.

Soft fruits already present - gooseberries, red, white and blackcurrants, Japanese wineberries, loganberries, blackberry, raspberries, strawberries, chokeberry, Japanese quince. There's also a huge mahonia plant and an area of buddleia and flowering currants.

Other crops already present - rhubarb, asparagus sorrel, horseradish. There's also the elephant grass I planted last year for biomass which has developed strong rhizomes.

Up till now these have been grown in quite separate areas, but a redesign of where pathways go should help link it all together. I plan to introduce more layers to include climbing plants, herbaceous perennials and perennial tubers.

I'll be adding in some herbs too, such as rosemary, oregano and creeping thyme. Comfrey too.

So here's a list of the new and wonderful additions which will pretty much turn the area into a fully blown forest garden.

Good King Henry - Also known as Lincolnshire Spinach. I am currently trying to germinate the seeds.

Caucasian Spinach - Hablitzia tamnoides - If I can get this growing, it should be a vigorous climber whose leaves can be used as a spinach substitute. If this works I won't need to bother trying to grow annual spinach each year, which always bolts ridiculously quickly.

Oca - Tiny little tubers. I've not tasted them before and at almost a pound a tuber I'll eat some of the produce and sell some for growing. Some of the tubers I received were frost damaged (should be safe outside if well mulched) but I have enough left. They are currently sitting in dry compost in a tub in a wardrobe in the garage. They are actually a type of oxalis and will provide a very attractive summer ground cover.

Yacon - I tried this once before but lost it over winter. However, the taste was great and the harvest huge. If I had saved the growing points properly in a frost free place I could have multiplied it a hundred times. I've started this off in pots in a warm room and they have all thrown up fresh green foliage. They will need potting on before they go outside later in the year.

Mashua - A perennial nasturtium whose tuberous roots apparently taste radishy. I'll probably just use this as a decorative climber to come back year after year.

Chufa (Tiger Nuts) - Actually the bulbs of a grass. These are harvested and dried for eating or replanting. I've tried a couple of the dried 'nuts' and love them. They are sweet and nutty, turning coconutty.

Day Lilies - Edible flowers and young shoots. They'll probably be a very occasional harvest, but will add splashes of colour in the understorey of the forest garden.

Perennial Kale - Taunton Dean Kale, Daubenton's Kale and Portuguese Walking Stick Kale. One survived from last year but the ducks or turkeys have demolished a couple of others, which is an expensive lesson for me to provide some overwinter protection. I'll make cages out of willow. I have ordered a couple of replacement cuttings of Daubentons which will hopefully root successfully. The walking stick kale will be raised from seed which came all the way from The Azores. In our cooler climes they shouldn't set seed so easily so will stay perennial.

Wild Garlic - I've purchased seeds. If they germinate, these will be going under trees as lush ground cover.

Wild Strawberry - the seeds have just gone in the freezer to simulate a winter. if successful, these will be used for ground cover to provide tiny jewels of flavour explosion!

Skirret - A very old-fashioned crop. A bit fiddly to grow and harvest but it will be interesting to try.

Babington Leeks - I purchased six tiny bulblets last year and five have come back over winter. These have gone into the new perennial area and should grow much more substantially this year. They start growing midwinter and will have died back down by June, thus offering a leek flavour at a completely different time of year to traditional leeks.

Bamboo - I discovered a couple of lost bamboos at the back of my herb patch. They've been there since we moved in and have just started to thrive. I have taken cuttings from a golden bamboo which grows really tall. This was something I found on YouTube but I had no hope of the woody stem sections throwing out new growth. But lo and behold one of them has. The other bamboo is much thinner but considerably denser. It has gradually expanded into a large clump hidden by a large bay tree. So I have been dividing it, not an easy task. 
I will harvest the bamboos for sticks and canes and might give the fresh shoots a try too. But really I am growing them mostly for their statuesque appearance and for the rustling of their leaves and stems in a breeze.

Siberian Pea Tree - I've just sown seeds so this is a long-term project. Siberian Pea Tree is a nitrogen fixer and will be an important addition to the forest garden.

Sorrel - non-flowering. I already have a large patch of sorrel, but it is quick to go to seed every year and looks messy. So I have purchased a non-flowering form which should give fresh leaves over a much longer period. If it grows well I'll propagate it and dig out the old stock.

Mushrooms - I cant wait to get going on these. I'm planning on growing shiitake, oyster mushrooms and winecaps. An exciting new venture and just perfect for the forest garden.

I am also trying some more exotic perennials which will get their own area in the polytunnel. I'll still have to lift and store every winter probably. So I am trying ginger, galangal, eddoe, apios (groundnut) and Madeira vine. 

The delight of perennial plants is that, once they've got a hold, they can easily be multiplied (sometimes too easily!)
