Even though we are well into June the weather has been wet, windy and cool at times. I am glad the tender plants such as squashes are still in pots in the greenhouse. I find many of the tenderest plants stay in good condition in a 1 litre propagation Air-Pot for a long time without getting potbound.

Sweetcorn barely ripens in a typical Scottish summer so getting plants to a good size early in the summer in the greenhouse really helps them along, The roots continually improve due to the air-pruning. The same is true for sweet potato, chillies and tomato.

Sweet peas have provided a really welcome bit of colour and sweet scent, they are blooming happily in a medium Air-Pot which means I can move it easily now it is in flower.

A Hosta which was divided a year ago has demonstrated the difference between Air-Pot growing verses a ceramic planter. The plant was split in two, one half went back in original pot the other into an Air-Pot of similar volume. Both had the same compost and growing conditions, the half in the Air-Pot now has twice the foliage and ten times the flowers.

An avocado I grew from a stone gathered in Madeira has produced massive healthy looking leaves, could we possibly produce a Scottish avocado fruit in a few years?
