it's typical, you've spent the last 4 months getting the garden how you want it, - the plants are thriving, the pots are full the fruit and veg is producing and...... you want to go on holiday.
If like me, you need a full 2 weeks away over the July and August period, but don't want to come back to a dessicated garden, what are your choices.
1) Get a friend or Neighbour to water, - hopefully there will be someone you can trust to come every week, or every couple of days if it's hot, to make sure that your most cherished plants make it through. If swapsies don't work, how about hiring a local student to do the watering? - but make sure you leave a list of what's important to water and how often, - I once came back to rotting potatoes and bone dry hanging baskets.
Do water, Newly planted borders, everything in the greenhouse, Vegetable plots.
Don't waste water on, Lawns or established borders (unless there are visibly wilting plants)
for more details about watering look at this post
2)Plant up your new plants into the largest pots possible or get seedlings and plantlets into the ground. Large pots (3 litre size) hold water better and for longer than seedling trays
3) Put any pots on Plastic trays, or rest them on thick Newspaper or capillary matting so that any runoff isn't lost to the plants completely and can be soaked up.
This Acer was bought at a show last year and has survived in a pot being planted up through various sizes for the last 12 months, - now it is in the ground, I don't want a week of dry weather to kill it and its newly released rootball, - so a watering bottle will direct 2 litres of water to the roots rather than spreading it through the surrounding soil.
5) make sure that your hose fittings or your watering cans are easy to find and at the ready - if you want to use waterbutt water, then 2 large watering cans are a must have, so that one can be filling while the other is used for watering
6) Enjoy your holiday, - just think the worst that can happen is that something doesn't make it and you can go plant shopping on your return.
