Beat the Heat: How to Keep Your Garden Thriving This June

As we transition from the foundation-building phase of May into June, our focus must shift from helping new plantings "establish" to actively "protecting" them against the increasing intensity of the summer sun and higher transpiration rates. June brings longer, hotter days and often higher wind speeds, which can rapidly deplete soil moisture.

Here is what you should adapt in your water management strategy for June:

1. Shift to "Maintenance Watering"

While May was about encouraging deep rooting, June is about managing the increased demand for water caused by rapid growth and higher temperatures.

• Increase Frequency: If you have had a spell of heat, move from your deep-weekly soak to a slightly more frequent schedule (e.g., twice a week), but maintain the intensity of the soak.

• Monitor Container Plants: If you have new plantings in containers, these will now need daily attention. Unlike ground-planted shrubs, pots have a limited volume of soil and will dry out exponentially faster.

2. The "Afternoon Check"

In May, morning watering is perfect. In June, you may need a midday or afternoon "check." Look for signs of "flagging" (leaves drooping during the heat of the day).

• Note: It is natural for some plants to wilt slightly in extreme midday heat to conserve moisture. Only water if the soil is dry and they are still wilted in the cool of the evening.

3. Review Mulch Integrity

Check the mulch you applied in May. With the heat, some organic materials may have settled or begun to break down. Ensure the layer is still a solid 5cm thick to prevent the surface soil from baking and cracking, which allows moisture to escape from deeper layers.

4. Weed Management is Priority #1

In June, weeds are at their most aggressive. They are not just eyesores; they are "water thieves." They will happily drink the moisture you’ve intended for your prize plants. Ensure your beds are kept clear so that every litre of water goes directly to your intended planting.

5. Utilise Efficient Equipment for Larger Scale

As the garden enters its peak growth phase, the time commitment to hand-water a large site can become overwhelming. This is when the efficiency of your equipment becomes a major asset.

• Scale Up Application: If you have large areas or hedgerows, use your SCH Supplies Towed Waterers to perform "drenching" sessions. Because these units hold significant volume, you can ensure that you are applying large amounts of water to a specific area in one go, rather than wasting time constantly refilling small cans.

• Targeted Hydration: Use this time to move away from general irrigation and focus on precision. Our range of waterers allows you to navigate right up to the base of hedges or trees, ensuring that the water reaches the root zone without being lost to pathways or foliage.

Pro Tip for June: If you have the capacity, install a simple water butt system at the end of greenhouse gutters or shed roofs. Even a short summer downpour in June can provide valuable soft rainwater, which is generally better for plants than treated tap water.
