2008 Review

This season we only opened to visitors during March, April and May. We had very bad luck with the weather on many of the open days. On two we had quite heavy snow resulting in nobody coming on those days. In addition there were several quite rainy days with only a half a dozen or so visitors.

However the plan of not opening during the summer did allow us to proceed quite well with the new garden development.

We started the works by creating a raised bed to dispose of some of the excavated material from the proposed water lily pond. The bed was built using ‘new sleepers’ capped with a 150 x 50mm treated timber,

Incorporated in the centre of the bed is an Arbour seat for viewing down the garden over the water lily pond

The bed has been planted with over 60 different Heuchera cultivars, 5 x Heucherella, 5 Tiarella, and a dozen different Japanese Maples. In addition two scented climbing roses and Solanum jasminoides ‘Album Variegatum’ have been planted to climb over the arbour. The result in mid summer was a bit like an instant Chelsea Flower Show exhibit as the plants are planted close together to reduce weed problems. We have grouped similar looking varieties of Heuchera etc. together to give a subtle drifting effect and to prevent a too spotty result. The more vigorous of the maples will need pruning in due course, to prevent them becoming too large.

The pond has gradually taken shape and now is slowly filling with water as it rains. We are going to be patient and not use tap water in the hopes we may not get too much of the ‘new pond syndrome’ with green water and blanket weed.

The pond is deliberately shallow for water lilies at around 30 inches (75cm) with most of the bottom covered with 9 inches (22 cm) or so of soil. There are ‘L’ shaped marginal plant beds in the corners and a circular bed in the centre for a Lotus plant (Nelumbo cv).

The basic pond construction is 4 inch thick dense concrete block-work, a 6 inch reinforced concrete bottom, a scratch coat and a top coat of render on the sides, and a screed layer of sharp sand and cement mix over the bottom. The render layers and the bottom screed had waterproofing liquid and ‘Reinfibres’ added for water proofing and strength. More concrete blocks were laid for the beds in a day by a local builder, with Linda and I doing the mortar mixing etc. Next we painted everything with two coats of black ‘A1 Pond Paint’, a two part, water based, epoxy resin paint, which was very easy to mix and apply. We are waiting with interest to see how it performs in the long term.

To finish off the top of the outside walls we had rather expensive black engineering bricks with a round corner laid by a professional hard landscaper. I scored these on the underside with a diamond stone cutting disc in an angle grinder for maximum adhesion as we hope to bring the water level up to the beginning of the curve. The bricks and mortar were also painted with A1 pond paint, this time clear.

We over estimated how much soil was going to be over after completion of the pond to level off the garden around it. We will therefore have to buy in soil later when the retaining walls have been constructed, again out of timber, to match the new raised bed.

On the left hand side of the pond  as you look down the garden, we have left a yard or so to be grassed in due course and recently planted up the remaining area back to the boundary hedge. We have planted a mixture of shrubs for autumn colour, spring, summer and autumn bulbs, and perennials for summer and autumn flowers.

We are hoping to build retaining walls, steps and paths to finish enough of the new garden in time to open to visitors in the spring. It will be hard as there is a good deal of work to be done.

The original garden hasn’t received as much attention as in most previous years, due to the time spent on developing the new piece, but we have done our best.

Our current task is to gradually dismantle a large Mimosa tree (Acacia dealbata) which suddenly died after flowering in the early spring. It has been a challenge as it must have been close to 40 feet (12m) tall and was over our large greenhouse. We don’t know why it should have died, but we noticed a bit off die back at the top during last summer. However as we say, every plant death in the garden usually means a planting opportunity!

2007 Review

We persevered with garden open days during 2007, again barely breaking even due to poor visitor numbers, as in recent, previous years. However the great enthusiasm and appreciation of the visitors we did have has encouraged us to open again in 2008.

The exciting news of the year was the purchase of the bottom of our left hand neighbour’s garden, a plot approximately 33ft by 90ft. Much of our original garden has now become a woodland garden, with many of the earlier planted trees now approaching forty years old. Due to the increasing shade it has become more of a spring garden than any other season. With this in mind we have decided to open the garden as normal in the spring, but to possibly close for the summer months to work on the new plot. We will be happy to open the garden by appointment to groups of six or more though.

The idea with the new piece which has a fairly open aspect will be to keep it that way, and concentrate on summer flowering plants in particular.  

There is an existing small vegetable garden, which will be kept and hopefully utilised fully. A new 10’ x 8’ shed has been erected, where our neighbour’s smaller shed had been. Guttering has been fitted on both back and front halves of the roof. Each drains into a water butt. The taps from these are joined by a flexible pipe, in the centre of which is a T joiner with another pipe leading to a plastic loft tank with a ball cock.

This will be a very convenient dip-tank for can watering, especially for plants which prefer rain water. We have already planted five varieties of Blueberry on the vegetable plot in front of the shed, which will benefit from rain water irrigation in dry weather.

We hope eventually to have a reasonable sized water lily pond. This will take us a while to create, due to the problems of disposing of the diggings. The levels of all the surrounding area will have to be raised and levelled, as it is impractical to remove excavated soil outside the new garden.

We hope to see you this spring.

2005 Review

A garden which is full up and has been for some years gives little scope for new projects and only major plant deaths or planned removals give scope for significant new plantings or the installation of new paths or artefacts. There were a couple of significant plant deaths, the Edgeworthia chrysantha ‘Red Form’ and the Arbutus x andrachnoides, but neither left a planting space of any significance. However we did decide to remove our Abies koreana which had become less attractive with size and the removal of its lower branches, to keep paths open. This did give us a square yard or two for the planting of some new numbered only species of Chinese Epimedium. We hope some of them may flower this spring, which will be exciting.

We decided to mark 30 happy years of marriage as we did at 25, with a piece of granite statuary. Early in the year we had been admiring a rather expensive and impressive, multi tiered stone pagoda in our local koi dealers, Koi Logic. We couldn’t really find a justification for a quite significant outlay, until we thought of our impending 30th wedding anniversary. We negotiated a saving by transporting it home ourselves and a couple of journeys and strained backs later, it was home and resplendent in our ‘oriental flavoured garden’.

Visitor numbers were low again but we were able to recoup our costs. We are opening again this year, but if we fail to reach that target it will be the last year.

Koi Pond report Early 2006.

Last autumn before we were able to cover the pond with the polythene sheet we needed to make new stressed arch supports. The previous ones constructed of our own home grown Chusquea bamboo had finally become unserviceable, as the humid conditions under the polythene and outdoor storage for the rest of the year had caused them to rot. We used plastic waste pipe, from the local plumbing shop, and wires, to make excellent new support arches for the cover.

Our koi pond of probably less than 2500 gallons is grossly overstocked with around 60 fish, some of are over 18 inches long. We find it hard to part with our fishy pets, although over the years a few have gone into our koi club’s (Crouch Valley) excellent koi auction.

Worrying about a fairly regular need to add medication to the pond for parasite infections, made us decide to make a considerable investment in a protein skimmer and ozone system this winter. This has been installed and running for only a few weeks, but the yellowing and cloudy ness of the water has been reduced dramatically.
I fully expect the growth rate of the fish to now accelerate and create new environmental pressures on the system, but for the moment at least it looks very promising.

We have also recently purchased and installed an inexpensive automatic feeder to do midday and afternoon feeds for us. This leaves an early morning, and sometime after the clocks change, an evening feed for us to do, when we can inspect and enjoy the koi.. It may even make it possible for us to get a few days away, without needing to ask our neighbours and children to feed the koi. We have only had about ten nights away from home in our nearly 31 year marriage. On the first night after programming it with the two feeds we did manage to miss a spurious midnight on with no off in the programming. This resulted in a massive pellet slick in the morning, to be netted out, and a lowering in the redox potential of the water. The system recovered after a few days, with no apparent harm to the fish. The water was cold at the time at about 13.5°C, or things might have been worse.
