Whether it’s Bali or Ballybunion, everyone wants to go away for a break. So what happens to your tunnel or your glasshouse while you’re gone?
Automatic watering is ideal. Be sure to set the controls well in advance so you’re sure it’s working well and regularly, and delivering enough water. Ventilation is easier; you can leave the vents wide open in mid-summer without fear of night frost but automatic vent openers are less liable to storm damage. They need no electricity and are easy to fit. Wedge doors nearly closed or screen them with wire mesh to keep out pets and wildlife.
Bribe a neighbour to keep an eye on it with free produce or a promise of looking after theirs later. Automatic watering and ventilators are good but nothing beats the human touch: unexpected problems can crop up (pun deliberate) and the comings and goings of neighbours deter thieves.
Move out pots to a sheltered, shady spot where they can get rain or be watered if needed. Remove more bottom leaves from your tomato plants than usual: the leaves on the top 70cm of the plants contribute most to their growth. This reduces their need for water and lets more fresh air around the plants, which helps control fungus diseases.
Remove flowers and developing fruit from plants to reduce the amount of unwanted and over-mature fruit growing while you’re away. It also further reduces the plants’ need for water.
Tidy up and clear out any weeds; also dead and dying leaves, dropped fruit and other plant remains that could host diseases. Bon voyage!
