Which? Gardening turns 30, what would you like us to trial?

I have no personal experience but I have been told on more than one occasion that glyphosate will do the job if poured into holes drilled in the stump. If done carefully, it should be safe.

What I have suggested will not remove the stumps, of course – only prevent further growth.

I agree. I have just bought a second hand Mantis classic which works very well on the allotment. It does bounce quite a bit on hard ground, which is tiring on the arms, and does not like long grass or large stones which stop it and need to be cleared. It turns the early season ground preparation from a massive unwelcome chore into a days work. I have also used it to “dig trenches”. The tines can be set to just go 2 inches deep so that it can also be used to weed between rows without damaging any but the most superficial roots. It is perfect for tap root vegetables which are undisturbed. Get the 4 stroke version if buying second hand and consider the electric version if you have access to power.

Apart from growing fruit and vegetables, I thought the whole idea of an allotment, or leisure garden as they are sometimes described now, was to do things by hand, take your time, not make a noise, enjoy the open air without petrol fumes and constant racket, and keep it under regular cultivation so that powerful tools were not needed.

Thoughtless use of noisy power tools can destroy other people’s pleasure in gardening and the outdoors.

I used to lug around petrol generators and became concerned that I could damage my back lifting the things in and out of the car. I bought an 800W inverter (with a higher surge rating), mounted it in a metal tool case for protection and added heavy cables with caravan-type clip on battery connectors. I added auxiliary terminal posts to the battery clamps of my car. When the car engine is idling, the alternator produces enough power to prevent the car battery being discharged, and if I’m using power tools infrequently, I don’t need to run the engine. I have been using my inverter when working away from home since before battery tools became available.

Would I be correct in assuming that this rather purist/idealised view of allotment cultivation comes from someone who does not have an allotment? Get out there, do the work and then come back and tell us how to cultivate an allotment.

That’s why it is so important to use them thoughtfully as set out in allotment rules.

You are right, Dugalheath, I don’t have an allotment but I have done the double-digging and the back-breaking preparation for vegetable cultivation on heavy clay. I am also aware of the hard work put in by the plotsmen at our local allotments doing it the old fashioned way without powered equipment. We now have too much garden at home to allow us to manage an allotment as well and we no longer require so much produce. I applaud those who do keep a good allotment going.

They way in which people choose to cultivate their allotment/garden vary greatly. Whilst I, and a number of others, have chosen to use tillers there are many who continue to dig and some who apply a “no dig” policy. I have never heard anyone voicing criticism of another’s choice and don’t’ see an individual’s choice in terms of right or wrong any more than I would their drinking tea rather than coffee or vice versa.

Hi Beryl – I have no experience of doing this, though I do run my pressure washer from a water butt.

Unlike pond pumps which operate at low voltage the pumps sold for water butts seems to be mains voltage (230V). For safety, it is vital that you have an RCD, either at the consumer unit or plug the pump into a portable RCD adaptor fitted to the mains socket. I would also buy a known brand from a retailer you trust.

Check that the water butt does not have a layer of leaf debris, or the pump inlet filter will soon block. Some of the reviews are not very positive and my guess is that people are using them in butts filled with debris. If you have a long hose you may need a higher pressure pump. The descriptions are a little unhelpful. For example the high flow rates quoted can decrease substantially depending on how far the water has to be raised and the length of the outlet hose.

Thanks Wavechange, I have checked the internet and there seems to be a variation in model pressure and price range. ‘Phil’ @ youtube.com – Priming a Hozelock Water Butt Pump demonstrates on how to assemble it.

Its as well I still have an RCD even though I rarely use the electric mower nowadays and thanks for the reminder to use it. There is almost bound to be some leaf residue at the bottom of the water butt so hopefully the long handled gripper will come in handy to tackle this. There may also be a problem controlling the end hose water supply in some models, seemingly not recommended due to a danger of the pump overheating. My main concern however would be the loss of water when returning to switch off the power.

Apart from that I might just give it a go before the next dry spell.

I think it’s well worth draining off the water and cleaning out the butt before fitting a pump, Beryl. My guess is that there will be a layer of decomposing leaves at the bottom. Here are instructions for a Hozelock pump: http://www.hozelock.com/wp-content/uploads/2015/04/2826-uk-33725-001-W-BUTT-PUMP-UK.pdf They advise sitting the pump on a couple of bricks to keep the it above accumulated debris.

The Hozelock pump has a small filter in the outlet hose connector and that is likely to block from time to time, but can easily be cleaned, so assume that the pump will have to be taken out of the water butt occasionally. That does not seem clever design because submersible pumps are normally designed to keep debris from getting into the pump, not out of it! I have a well designed submersible pump but it’s too big for use in a water butt. I bought it about ten years ago when I was living near a river and my home was nearly flooded. 🙁 Thankfully it has never been used.

I found that my submersible pump (Clarke Hippo 2) was supplied with different size adaptors, including a small one that fitted ordinary hose pipe. With a long hose attached, the pressure is not high, but it’s adequate to run a small sprinkler. Thanks for helping me find a use for the pump, Beryl. 🙂

It would be good if Which? would test the water butt pumps because they do seem to differ, for example in how much water pressure they produce.

I’m familiar with inline pumps and wondered if they were sold for use with water butts, on the basis that it would be easy to connect one to the outlet tap. I turned up the Hozelock pump you mention, which offers a decent pressure. I wondered why the manufacturers suggested using a dip tube and then realised that a water butt tap would restrict the flow too much. The other complication is that it is necessary to prime this sort of pump.

At my previous home I considered using an old mains-powered Stuart-Turner centrifugal pump to water my small vegetable patch from water butts. It was not designed for outdoor use so I took the easier option and raised the water butt sufficiently to provide the pressure needed.

When we had a much larger garden I coupled two water butts together with a long hosepipe fitted near the base of both butts. The water in the one at the far end of the garden was at the same level as that in the one next to the house. It was useful for filling water cans but this would not work so well if there was a significant difference in level between the bases of the two butts [for example, if the garden was on an incline]. Most watering was done using mains water and we also had an irrigation system with several branches and that was time-clock controlled.

I use a pressure washer to clean the car. My tap water is very hard and leaves streaks on the windows, whereas rainwater is soft and I can get away with not using a chamois leather. 🙂 Knowing that the water butt attached to the drain pipe from the garage roof would accumulate a layer of debris, mainly from decomposing tree leaves, I linked my second water butt at the top, so that it would fill up when the first butt is full. I’m hoping that this will mean that little debris accumulates in the second water butt, so that the inlet filter on the pressure washer does not need cleaned very often.

My present pressure washer works fine from a water butt on a stand whereas my previous three pressure washers did not. I don’t recall Which? mentioning this in their tests.

Apparently if you cut and separate the legs of a pair of women’s lacy tights you can fill one leg with charcoal and hang it inside the water butt and wrap the other leg around the inlet pipe to act as a filter to trap any debris entering the butt reducing the need to clean.

After no more than 8 months the water butt fed from my garage gutters contained a layer of organic debris, the only recognisable thing being lots of winged seeds like those produced by sycamore and maple trees. I’m the wrong gender to have women’s tights, Beryl, but that would be better than fitting a filter in the gutter and have to climb up and clear it on a regular basis.

I hope that Which? will test water butt pumps, both submersible and inline types.

You can buy them online Wavechange but make sure you avoid the Nora Batty ones as I would imagine they could block the water supply as well as the debris 🙂

Indeed. Maybe we should discuss bloomers next, as in the kind that add a little colour to even the smallest garden.

It never ceases to amaze where a bit of humour can lead to on Convo! Bloomers led me to a more practical garden idea such as the Brassica genus, cabbage, broccoli, cauliflower etc. which contain goitrogens, not recommended for people such as myself who have inherited hypothyroidism. Goitrogens can induce hypothyroidism and goitre (hence the name) in the absence of normal iodine intake.

I was always advised to avoid these vegetables but never understood why. Mystery now solved Wavrchange and it all started with water butts!

Lawn?
You could always have wild flower sections. 🌾🍀🌼🌾☘🐌🌾🌷🐝🌾🍄🌾

I recall you posting that you had obtained four tonnes of manure, Malcolm, and I assume that this needs to be dug in. My father had a large garden with heavy clay. It took many years of digging in compost to make it into good soil for vegetables and fruit. A cultivator would have saved him a great deal of work. Looking at Google Earth I see that his wonderful garden has become a lawn. 🙁

i always leave compost – home made or otherwise – on the surface and let the worms do the work – they are all on internships. Except when I want a seed bed, then I shuffle the surface with a spade. The best cheap soil conditioner I had was spent mushroom compost. I also had good crops of mushrooms but the farm has closed. I’m not sure of the qualities of my cow manure yet, but moving it kept me fit.

OK, but I had assumed that digging would improve the drainage of clay soil and digging in compost make it less heavy.

I believe the worms improve the drainage.

Many many years ago when plastic flowers started to arrive from HK, our neighbours concreted over their back and front lawns, painted the concrete green, surrounded the “lawns” with hollow concrete blocks and “planted” polythene flowers in them. I suppose these days it might be on display at Chelsea or Tate Modern.

Thanks dugal 🙂

There are numerous “no dig” videos on YouTube. I am subscribed to 5 or 6 of them for the continuing story.

This is one of the best. People with enquiring minds.
youtube.com/channel/UCVQCQJyZQcIioTDQ4SACvZQ
if the look does not work for you the channel name is “Back to Reality” and they have been trying a variety of no-dig methods. I have no doubt there are some English gadners also doing videos.

The charity HDRA now trading as Garden Organic have indicated this site
charlesdowding.co.uk
which looks pretty darn good.

I considered raised beds but may well go to no-dig for a lot of the area and perhaps use a machine where I will be planting long rows for things like sunflowers where I am not fussed about them all flowering together. Anyway we will see as I have a new garden this year and an unkempt field to consider. Different soil, latitude, aspect etc – it does not pay to be too ambitious.

I just accept that I have it and pull out anything above ground whenever it appears. The idea is that if it cannot photosynthesise then it cannot survive. It is too early to say if this approach works. However, deep digging does not.

Glysophate whilst they are young I would think preferable to allowing them to grow. However given the evidence against glysophate I am running down what I have or may even dispose of it.

I do often just keep attacking weeds on a morning walk around the garden as dugalheath suggests. Enlarging the garden may mean much longer morning walks : )

Thanks for the link Patrick Taylor.
Scary….
I attack horsetail with it in small sections so I can prevent the wildlife getting at it.

There is plenty of evidence why glyphosate (e.g. Roundup) is best avoided, Patrick, and you have provided one example. It’s best to assume that all chemical pesticides are harmful because our metabolism is so similar to that of plants.

I have started sewing green manure as a means of supressing weeds and enriching the soil, especially if I do not plan to plant for some time. Areas under trees have a long term manure. I bought from this site. https://www.thegrassseedstore.co.uk/product-category/green-manure/
There are a number of different types for different applications. I make sure the ground is pretty weed free before I start which means that I rotavate it first. I am waiting to see if it will outcompete the weeds. So far I need to core out the dandelions and dock with a special weed extractor tool from Tesco (not the Wolf one) leaving the surrounding green manure relatively intact. Some areas take well and some don’t so I will reseed in a few weeks.

I have been very satisfied with some own-label garden tools I have bought from Wilko, including a shovel [strong but not too heavy], sieve, rake [good tines and braced head], rubber tubs, and gloves of various types. I also use their path weedkiller which is much cheaper than the big brands and seems to be just as effective [given that half of it goes beyond the target anyway]. I have looked at – but not bought – garden tools from Homebase or B&Q because their designs seemed unnecessarily strange and clumsy; I could see the intention to make them more ergonomic but they were too heavy for prolonged use. I haven’t found a trowel anywhere that wouldn’t bend or break within a short period of use [including Wolf products] so I still use my father’s ones that were probably bought in the late 1940’s.

I successfully used Lidl anvil-loppers to deal with pruning roses and shrubs that needed something more than secateurs. When I moved home and needed to prune trees the aluminium anvil bent and then broke. I had realised that this was a weak point when I had bought these loppers but they were fine for the light duties that I had originally intended. I’m now using Wilkinson Sword loppers that were heavily discounted old stock in The Range and they have seen a lot of use in the past year.

The only cheap gardening product I can recommend is pruners like the ones in this photo:

These plastic ones have a ratchet that gives additional leverage and though they won’t last for ever they are quite nice to use. I have a friend who helps me keep the shrubs under control and she now selects the cheap plastic pruners rather than the Felco or Wilkinson-Sword ones. I don’t think these plastic pruners are still on sale but I am still using the ones I bought years ago.

I certainly don’t believe that ‘you get what you pay for’, Dugal. Like John, I bent a fair number of trowels but now have a stainless steel one that has survived heavy use. It’s more curved than its predecessors, which makes it stronger.

I bent an trowel recently and bought a stainless steel one from Tesco. Manufacturers need to concentrate on the strength/material of the shaft connecting the blade to the handle. I guess reductions in the amount of material used in more modern tools mean it has got weaker. I also broke a steel spade and replaced it with a Wilko stainless steel one. So far so good on both products. It might be worth Which testing the flexural strength of various trowels.

Hi Dugal. I edited my comment to add the comment about trowels, having read John’s post. You are absolutely right about many modern tools being weaker, so it’s important to inspect products carefully for obvious design faults.

I suspect it can be quite difficult to make an accurate assessment by sight alone. I believe tools are made from tool steel which comes in a number of grades. I presume that certain grades are for certain purposes but imagine that trowels can be made from a basic steel which is cheaper and not as “strong”.

I had a large Maple tree removed professionally after the roots toppled a garden wall. They used a stump grinder. As I recall the factor determining the size of the grinder was weather it would go through the door at the back of the garage. It did and they ground out the stump well below ground level so that the wall could be rebuilt. On replanting it was as if the tree had never been there. Although I cannot tell you the exact depth of the grinding it was deep enough.

Thanks Dugal. I guess the tree surgeon did not offer to remove the stumps was the access problem. The annoying thing is that there is plenty of room at the other side of the house but a substantial fence in the way. I had better measure the doorway in the garage.

Otherwise, call in the Royal Navy to do a trial Field Gun Challenge over your garage roof. It would make a change for them from the usual chasm.

That possibility had not occurred to me, John, but I’ve a feeling it might annoy the neighbours.

When I had the tree surgeons remove my maple tree they seems conversant with the problems of getting access to the back garden with stump grinders. They knew the standard size of doors and which ones would go through so I guess there are machines that will go through but I cannot tell you which. Maybe ask tree surgeons or hire firms.

You are right Dugal. I looked at a couple of local companies and there are small machines that will do the job. I need to coordinate this with a friend to make hiring a machine more worthwhile.

The cost of hiring can be quite steep. After receiving a quote I then go and look to se if it is cheaper to buy one. For things you use frequently such as drills, impact drivers etc it is but how often do you need a stump grinder.

You have raised an interesting point which crosses my mind now and then. I expect Which? to test products and Gardening Which? does gardening products. For me this means machinery, compost seed germination results, tools etc. And even garden furniture perhaps.

I have gardening magazines and sites for plant advice. This may seem slightly arbitrary but gardening sites generally do not do “testing” of product. Therefore Which? would be THE reliable source – however the X hose piece revealed a bit of a gap in testing and what was related to people. I was much saddened by this.

Unfortunately the way Which? is organised I cannot simply post my report on say x garden furniture, or what site is good on sharpening tools. Given the number of people with gardens one might assume that members could happily have a forum.

There is the Community Forum however as that has been from the start a miserably difficult forum to access – it is barely used. Also even if you subscribed to Gardening Which? you do not get access to the Forum.

This may be changing as I have pointed out to CA recently that their stated intention that they use it for CA governance announcements fails to meet Company Act requirements if Ordinary Members are barred from accessing the information unless they pay additional money.
