Chilean Butterfly flowers

Also known as Fringe flowers and Poor man’s orchids Schizanthus are a glorious way of filling a glasshouse with summer colour. Coming from S. America this small genus related to potatoes derives both common and scientific names from pretty pansy like blooms. These have split corollas and look much like orchids, and even more like […]

Midsummer suggestions for a productive garden

Fresh tomatoes eaten straight from the plant, are one of the great pleasures of summer. So to get the best from your plants, keep them well shaded, ventilated, fed and watered throughout the growing season and ‘pinch out’ the stem just above the fourth truss to ensure that the fruits ripen. Feed with Epsom Salts […]

Is it worth growing strawberries?

Strawberries are possibly the plant, or fruit that just about everybody wants to grow. And with the extortionate price of these fruits in the shops and the deliciousness of these rich red fruits, it’s no wonder that everyone wants to grow them.

Over the years I have made a lot of gardens in many parts of the world. They have embraced all sorts of styles and situations from the very formal, to the wildly unkempt from the classical to the modern. However, I think I confidently say that the garden we have made for Horatio in Scotland […]

Extending the flowering season and other seasonal suggestions.

Remove dead or fading flowers from ornamental plants to encourage a longer flowering season. Most can be removed by snapping them off between your finger and thumb or removing them with scissors. It is a particularly useful exercise with roses, because you can wrap your hand right round the petals, gathering them all before they […]

How to Grow Penstemons

Your greenhouse can revolutionise your garden, because it’s possible to grow a whole range of slightly tender plants, because you can raise them from cuttings. Many of these slightly tender plants come into their own from late-summer onwards, so they extend the season right up until winter beckons. This helps late-flowering pollinators (and gardeners)  to […]
