Hot, dry days can take a toll on even the healthiest garden. At Nunan’s Florist & Garden Center, we understand how quickly a thriving plant can show signs of stress when temperatures soar. Whether you’re growing vibrant annuals, hardy perennials, or container gardens, it’s important to recognize heat stress and know how to respond.

Signs Your Plants Are Heat-Stressed

Knowing what to look for is the first step in helping your plants recover. Common symptoms include:

• Wilting – Leaves droop or curl even if the soil is moist. This can be a sign the plant is struggling to take up water fast enough.

• Leaf scorch – Look for dry, brown edges or spots, especially on broad-leafed plants.

• Flower drop – Many plants will abort flowers or buds to conserve energy.

• Yellowing leaves – This often means root function has been disrupted due to excess heat.

• Slowed growth – Plants may pause blooming or pushing new foliage until conditions improve.

How to Help Heat-Stressed Plants Recover

Don’t panic—many plants can bounce back with a little help. Try these practical steps:

1. Water Wisely

• Deep soak in the morning – Water early and deeply to hydrate the roots before the sun is intense. Avoid quick, shallow watering.

• Check soil moisture – Use your finger or a moisture meter to see if water is reaching below the surface. Dry soil below damp mulch is a common problem.

• Don’t overwater – Overcompensating can suffocate roots. Let soil dry slightly between waterings for most plants.

2. Mulch Matters

• Apply a 2–3 inch layer of organic mulch (like shredded bark or compost) around the base of plants. This helps retain moisture and regulate soil temperature.

3. Shade Smart

• Use shade cloths or garden umbrellas to protect delicate plants from the harsh afternoon sun.

• Move containers to shaded areas if possible, especially during peak heat.

4. Pause Fertilizing

• Avoid fertilizing heat-stressed plants. Excess nutrients can burn roots or force growth when the plant is trying to survive.

5. Trim with Care

• Remove scorched or dead leaves to reduce stress and improve airflow, but avoid heavy pruning until temperatures cool.
