READER DAN asked a great question that reveals a tip you can use right now to prevent powdery mildew this summer on your garden phlox:
“The biggest problem I encountered was with the Phlox I planted,” Dan wrote. “The leaves developed a terrible fungus and it slowed its growth terribly. When I first spotted it, I did some research and decided to use an organic fungicide. That worked alright, but the fungus came back. Then, I tried an organic remedy I found on the internet: spraying with a milk solution. That worked less well. The poor plants were so overcome with the black fungus that they eventually withered without flowering late in the summer. I finally cut them down. Now they are starting back with strong green growth and I’m pleased, but I wondered if you had any advice for treating Phlox fungus.”
One of the best non-chemical ways to deal with powdery mildew, I replied, which Phlox paniculata is so prone to in our humid summers, is to prevent it by improving air circulation in and around the plant. Do this as shoots emerge by “thinning” the clumps—just use your finger (or a pruner if need be) to knock out like a third of the shoots, to space the remaining ones less closely together. The plant will breathe better, so to speak, and that will help prevent the fungus from overtaking it.
Another good preventive step is to spray starting before the outbreak occurs with a homemade anti-fungal like a solution of water, baking soda and horticultural oil. Rosarians do this with their roses to prevent black spot, another fungal pest; recipes vary but it’s approximately a teaspoon of baking soda and a teaspoon of horticultural oil (from the garden center) in a quart of water, or a tablespoon or so of each in a gallon.

A fad in modern architecture and gardening or a necessity to bring back nature into industrialised densely built urban landscapes? Living green walls are becoming more and more popular, so we decided to explore the benefits, installation and maintenance process of these structures. Read on to find out how long they have been around, why so many buildings are having them, and how you can make one for your home.
Q: We have a Malus (ornamental crab apple tree) in our back garden, which has grown from small to its present 20ft over 15 years. It buds and flowers nicely, but then turns a bit shabby. It doesn’t seem like a healthy tree. Can you help? We are debating whether we need to remove it and replace it. If it does need to be removed, what replacement would you suggest? CF, Co Kilkenny
In Yorkshire we are lucky to have several gardens designed using the theme of a Himalayan Garden. The Hut near Ripon at Grewlthorpe is  ‘The Himalayan Garden’ with all the plants you would expect in such a setting including
A cheap tip for members of the RHS is to borrow books from their libraries. I am reading the entertaining Techniques and Tips for Gardeners from the BBC Gardeners Question Time Team.
Britain has some of the best gardens in the world. The choice of which to visit is far larger than this selective list but at least it gives you somewhere to start planning this years outings.
In the cold wet winter it is a good time to plan where to visit as the year improves. The South West is the obvious place to start your visiting tour of gardens containing exotic plants.
China is one of the great destinations for visiting gardens. The influence over garden design and the vast array of plants and flowers is secondary to the investment in time and dedication demonstrated in so many great locations. This is just a selection of those you may consider visiting if you can make the journey..
Peace is not just the absence of war it can be a reflection of a personal inner tranquility. To many gardeners peace may be a state of harmony with nature. It is a theme of several ‘hard landscape’ projects and sculptural works as shown by the selection of Peace gardens below.
Holland Park has some Zen like features but fails my Zen test. The classic elements of a successful Zen are stone, sand or gravel, water, plants and space. Then there is a question of balance between yin and yang. Cramped or cluttered gardens inhibit the flow of spirit so space is potentially the key ingredient of a Zen garden.
I was picking the Czar plums to make more jam when a wasp was disturbed from eating it’s lunch. Wasps go for my plums just as they are at their sweetest best. My problem was I couldn’t see which plums had a wasp in the fruit if they were above head height or facing away from my hand. The resulting sting set me on the trail of other stingers in the garden.
For over 25 years I have gardened a rockery or rock garden on a triangular patch of poor soil. I progressively scrounged and collected a range of granite, limestone and sandstone rocks and added them piecemeal. I aspired to growing alpine plants and recognised good drainage and shelter from winter wet weather would be key but that is as far as my planning would go. For the first couple of decades I was busy at work and wasn’t able to put in the effort of looking after small but hardy alpines.
Not what you would expect for a garden called ‘The Phoenix Garden’ in the middle of Tottenham Court Road near Crown Point. It isn’t a phoenix from the ashes of a great fire or a WW11 bomb site at but was built on a disused car park in the 1980s. It may be part of an overflowing burial ground for St Giles-in-the-field church back in the 1600s and is reputed to be the last surviving Covent ‘Garden’. The entrance is located in St Giles Passage
