7: What to do in the garden in July

Welcome to July, the sun is shining, and the garden is at its peak with an explosion of colour from the flowers in full bloom at the moment. 

As potentially the warmest and sunniest months of the year, this is the time to really enjoy all of the hard work that was put in during winter and spring. Be sure to be vigilant and keep on top of watering plants during hot spells, especially new plants and newly planted trees and shrubs. 

The warm and moist temperatures of July will encourage the pests to multiply, causing pests such as aphids to gorge on unsuspecting plants. Most of all, make sure to enjoy the garden you have worked so hard to create all those months ago with wonderful time spent amongst nature and greenery.
