Summer Watering Guide

 

Summer Watering Guide for Franklin County Gardens

Franklin County enters Summer 2026 under a Drought Warning, and we need to consider our watering practices. A Drought Warning means that water supplies are stressed and conservation measures are needed to manage our limited resources. We are running behind seasonal norms for rainfall and gardeners should expect soils to dry more quickly and plants to show stress sooner than in an average year.

A garden drinks in many different ways, and understanding those needs is the difference between plants that merely survive and plants that truly flourish.

💧 Watering Basics for Flower Gardens, Vegetable Beds, and Lawns

Healthy gardens depend on steady, deep watering—just enough to keep roots growing downward, not so much soil stays soggy. Most flowers and vegetables need about 1 inch of water per week, whether it comes from rain or your hose. Lawns need roughly the same amount, though cool‑season grasses can tolerate brief dry spells.

🌼 Flower & Vegetable Gardens

• Water deeply, not lightly. Aim for soaking the top 6–8 inches of soil. Shallow sprinkling encourages weak, surface‑level roots.
• 
  Morning is best. Early watering reduces evaporation and gives foliage time to dry, lowering disease risk.
• Check soil before watering. If the top 2 inches are dry and crumbly, it’s time.
• Mulch helps. A 2–3 inch layer of mulch slows evaporation and keeps soil evenly moist. Keep mulch away from the stem.

🌱 Lawns

• Water early in the day to reduce evaporation and fungal issues.
• Infrequent, deep watering (once or twice a week) is better than daily sprinkling.
• Let grass grow a bit taller during hot, dry periods—longer blades shade the soil and conserve moisture.

🌧️ Using a Rain Gauge

A simple rain gauge is one of the most useful tools a gardener can own.

• Place it in an open area away from trees or buildings.
• Check weekly totals—if rainfall is less than 1 inch, plan to irrigate.
• For vegetable gardens, keep a small notebook or phone log to track rainfall and watering patterns.

Using a Bubbler to Water at Ground Level

A hose‑end bubbler (sometimes called a “watering wand bubbler” or “gentle‑flow bubbler”) is one of the easiest ways to deliver slow, deep moisture right where plants need it: at the soil surface, not the leaves.

Soft, low‑pressure flow. Bubblers release water in a quiet, gurgling stream that won’t splash soil onto leaves or erode mulch.

• Perfect for flowers, vegetables, and young shrubs. The slow soak encourages deep root growth and reduces runoff.
• Excellent for drought care. Place the bubbler at the base of the plant, let it run for several minutes, then move it to the next plant.
• Tree watering made easier. Instead of spraying the trunk, set the bubbler in a wide ring beyond the canopy dripline and let it seep into the full root zone.
• Water early in the day. You’ll lose less to evaporation and help keep foliage dry.

A bubbler turns watering into a calm, controlled process—especially helpful during dry spells when every drop counts.

🌳 Don’t Forget the Trees

Trees—especially young or newly planted ones—need special attention during low rainfall or drought. Their roots extend well beyond the canopy, so watering only at the trunk won’t help.

• Water in a wide ring at and beyond the dripline.
• Apply water slowly so it soaks deeply into the root zone.
• Mature trees may need a deep watering every 2–4 weeks during extended dry periods.

💡 KNOW HOW: Measuring How Much Water

If you’re watering with a sprinkler, you can place a straight‑sided container, such as a coffee can, within the spray pattern. The depth of water collected shows how much is reaching the soil over a given period. This method helps you understand whether your sprinkler is delivering enough moisture to penetrate the root zone.

To make sure your trees are getting the right amount of water during dry periods, it helps to measure how much you’re actually applying. One easy way is to check your hose’s flow rate using a five‑gallon bucket. Set the hose in the bucket and time how long it takes to fill. If it fills in five minutes, your hose is delivering about one gallon per minute, which lets you estimate how long you need to run it to reach your target volume for a deep soak.

Some gardeners prefer tools designed for slow, steady watering. Slow‑release watering bags and drip rings apply water gradually and directly to the root area, which is especially helpful for newly planted trees that need consistent moisture to establish.

As a general guideline, newly planted trees benefit from about ten gallons of water per week applied slowly enough to soak deeply. Larger, established trees may need more, and a common rule of thumb is to provide roughly twenty gallons of water per inch of trunk diameter measured at breast height. No matter the method, applying water slowly helps it soak into the soil rather than running off, and a layer of mulch around the base helps the soil retain moisture and keeps roots cooler during hot weather.
