In most cases, to say that your garden will miss you when you go away on holiday would be a major understatement. This is because most gardens go untended during this time, and they absolutely feel ignored. Luckily, there are measures that you can take to keep your lovely garden polished even during your time away.
Plan to spend a descent chunk of time out in the garden before you depart. By cleaning things up now, you will assist in continued growth and success. Deadhead the finished flowers from your annuals and use a wetting agent on your garden when you water it to assist rainfall in seeping through. Tie any drooping vining plants loosely to a trellis or fence if you are training them to grow upward.
Get the mulch out and spread it after a good rain, or you have thoroughly drenched it yourself. This way you aid in keeping roots damp and reduce evaporation of the water from the soil. Remember, even when you do a good covering of mulch that you want to exclude covering trunks and stems of your beauties.
If you are leaving any vegetable plants behind, remove any overripe veggies so they will not fall to the ground while you are gone. This will help to support a healthy growing environment, as opposed to attracting any disease. Now you should not worry about the garden while you are on holiday.
