shady greenhouseI’ve previously had a question about acquiring a second greenhouse and what it could be used for. Today’s question is from Tony Sharp of Hertford and also involves a ‘greenhouse gift’. Tony asks:

‘My parents have offered me their old greenhouse, but the only available space for it in my garden is generally shaded. Is it worth the trouble of moving it to my place?’

Tony, it is certainly worth it. The great majority of popular greenhouse and pot plants prefer shady conditions when in the decorative stage- but good light, which does not mean direct sunlight under glass, is essential for them in their early stages of growth. If there is too much gloom, growth will be weak, straggly and pale. If your greenhouse is going to be very shaded, the use of a cold frame or other mini garden frame in a more open, sunny position might provide the right light levels for the early growth stages of some plants.

There are also many plants that revel in considerable shade, apart from the low growers suitable for placing under the staging (more on this below). Examples include:

  • Many ferns for both cool and warm conditions

  • Norfolk island pine (Araucaria excelsa) in its juvenile form

  • The climbers, Chilean bell-flower (Lapageria rosea) and Hoya carnosa- both with attractive flowers

  • Many ivies

  • The Schefflera foliage species

  • Camellias, which flower very well in pots when young

  • Streptocarpus

  • Gloxinias

  • Many of the Gesneria family

  • The ‘forest cacti’ such as Schlumbergera and Rhipsalidopsis

  • The annual Exacum affine, which is sweet-smelling

  • Anthurium crystallinum

  • Various palms

And there are many more possibilities to choose from depending on the temperature that can be maintained in the greenhouse.

I mentioned using the space under the staging in the greenhouse above. If you have a glass-to ground greenhouse the lighting conditions will probably allow this area to be used for a propagator or those plants that like slight shade. If, however there is considerable shade (as you might get with a solid wall greenhouse), only shade lovers can be put there- but once again there are lots of these to consider. Many houseplants like the sort of lighting you get in this area (and may even be raised there); so, too, do tropical  plants and exotic foliage subjects if warmth and humidity is adequate. Good crops of mushrooms can be grown and, if an area is blacked out, it can also be used for blanching and forcing crops such as chicory, rhubarb and sea kale.

You have staging- what can you use the area underneath for?
You have staging- but what can you use the area underneath for?

I’d suggest that you don’t use the under staging area as a store for general garden stuff (eg plant pots and trays) as these and other ‘junk’ can soon turn into places where pests and diseases will be encouraged. However this area can be useful as a store for tools that are used regularly in the greenhouse, as well as containers of seed and potting compost- as long as these can be effectively sealed (I’ve seen a bag of compost left open in a greenhouse and soon become a home for ants!).

28th May 2014

Dear Walter

It’s been a busy May, Walter- ‘as usual’ I suppose you  might say! The last couple of days have seen heavy rain, but thankfully I managed to get out for a full day in Old School Garden on Monday, anticipating the rain by planting out lots of seedlings. This stage of the year also coincides with the cleaning of the (now empty) greenhouse and getting in the 12 different varieties of tomato and chillies my friend Steve has given me – plus a cucumber.

Today, as the weather is clearing up I’ll be out putting in a cane framework up which to train them. Or rather, most of them, as this year Steve has given me two varieties of tomato which don’t require tying in and training as cordons. Roma is a ‘determinate’ variety so should be grown as a bush (it doesn’t need it’s side shoots pinching out), and Marmande is ‘semi determinate’ which means limited pinching out is required. He’s also given me a ‘ridge’ cucumber which I’m going to try to grow outside in a pot.

I’m also feeling quite pleased that I managed to find a good use for the old compost I removed from the greenhouse. I grow my tomatoes in bottomless pots sunk into the ground (the so-called ‘ring culture’ method), so a dozen holes need to be dug to make way for the pots which are then filled with growbag and other compost. I’ve used the old compost in a plastic bin that once ‘graced’  the courtyard – you may remember I’d bought some rather nice large terracotta pots to replace the utilitarian plastic dustbin and pots that previously contained the peach and an olive bush? Any way, I thought I’d have a go at growing some carrots in the dustbin and the old compost. This is very friable and lacks any stones, so seems the perfect medium for this. So the bin is full and I’ll hopefully get round to sowing the carrots later today – they’re a variety called ‘Nigel’ given to me at Christmas by Steve and his wife!

The rest of the kitchen garden is also looking pretty full- potatoes have been earthed up a couple of times and the first flowers are forming on the first earlies. The Brassica cage is also looking increasingly full with Cauliflowers, Calabrese, Spinach and Broccoli. Rainbow Chard and Leeks are bulking up and the first Broad Beans look like they’ll be ready to pick very soon. My sowings of Parsnip, Carrot and Beetroot are also coming along nicely. We’ve had plenty of Lettuce in the last couple of weeks. The Strawberry bed has been mulched with straw and as a bit of fun I’ve bought a plastic owl with a swiveling head to see if I can deter pigeons and other birds from the swelling fruit and other goodies in the garden (they usually go for my raspberries which are also looking promising this year)!

I’ve just about managed to catch up with the major weeding- just one area of the woodland edge to do and then I think I’ll mulch this with wood chippings to try to keep the weeds down. I’m hoping to do the same in the fruit cage once I’ve been through with the hoe later today. Oh, and some good news. You remember we had that extension put on about ten years ago that created Deborah’s Study? Well, I had to move a rather old Philadelphus bush and so put it in the main mixed border as a back drop to other things. It’s never flowered since, despite some careful successive pruning out of old wood, and encouragement of new growth. Well, it may be weather-related, but its covered with flower buds this year – I’ll post a pic when it comes out!

I’ve still got some half-hardy annuals coming through (I spent a couple of hours inside the shed potting these up while it poured down outside, yesterday). However,  I’ve managed to plant out most of these and especially the front bed which is my ‘homage’ to Victorian bedding and one or two other spots to add complementary colour or texture to perennials that will flower later- e.g. putting some golden-yellow looking Amaranthus in with the blue Agapanthus.

Several things are looking good here, including the rapidly filling mixed borders, so here’s a slide show of some of the highlights.

Unfortunately I didn’t manage to get the number of takers necessary to run the various gardening courses I’d planned for May and June, but I’ll try again the autumn, which seems the time most people do an evening class, especially if it’s garden -related. My work in other gardens has also been rather hectic. The sessions at Fakenham Academy have really begun to take off. The children seem more focused and interested and are starting to ‘own’ their plots, which are fast filling up with all sorts of food crops and some annual flowers to add colour and scent as well as attracting the pollinators of course. Unfortunately an assortment of pests is also posing a challenge- rabbits, mice and pigeons in the main. So remedial action has been necessary to try to prevent further damage- we had great fun last week trying to erect a pigeon-proof cage over the brassicas!

We’ve also got some tomatoes, cucumber and aubergines growing in the greenhouse. Also in Fakenham the project at the Community Centre to clear and plant a border next to the two hundred year old ‘crinkle crankle’ wall, has gone well. I, together with volunteers and children from the local primary school, planted this up last week. Now we wait for the plants – which I’ve positioned in repeating drifts of different colours, textures and forms to reflect the wave of the wall -to get hold and push on to do their stuff. I’ll post some pictures of this next week.

Another pest controller- I hope!

I was also pleased to be positively mentioned by one of the Inspectors at a recent Ofsted Inspection at the local primary school, where I was showing the children how to weed and earth up potatoes and explaining why we do this. This school (which now has level 5 of the RHS Campaign for School Gardening award), is shortly to host a training session for other local schools interested in school gardening activities. I’ll let you know how it goes.

How is your garden looking, Walter? I expect your orchard has  finished flowering by now, but I have fond memories of visiting you and Lise one spring and seeing all the beautiful blossom there. From my own garden, it looks like we’ll have another good year for fruit- there certainly seem to be a lot of plums forming on the tree and I can even seen some (and cherries) on the young fan- trained plants in the kitchen garden.

So, I think its getting to that time of year when we can take the foot off the accelerator a little and begin to enjoy the fruits of our labours! Hopefully that last major bit of weeding will be done by the end of the week and I can then get the remaining flowers planted out, as well as hoeing here and there to keep the weeds down. And maybe then a bit more sitting in the sun!

Having said that, I do think there’s something very satisfying about forking into a light, damp soil and pulling whole strands of Ground Elder root out (and of course trying not to breaking any of it off in the ground)!
