20 Questions & Answers on Extreme Heat Recovery

We’ve received quite a few questions during the recent heatwave about how to revive stressed plants, and we are more than happy to help! These are some of our most requested questions and answers that will help you prepare for extreme temperatures in the future.

1. How do I help my lawn? I am watering it every day, but it’s still getting fried!

Turf grass is very thin in its root system. The recent temperatures caused water to evaporate quickly from the soil. Your grass may have been sunburnt despite regular watering. Our Northwest grass blends are not designed to handle these conditions. However, your grass will recover if you give it regular watering and fertilization throughout the season.

2. My hydrangeas seem the most affected by the heat. Any suggestions for recovery?

Hydrangeas really struggled. It was hard to see. It was very difficult to watch. The spent flowers can be trimmed by cutting just below their flower buds. Fertilize. Hydrangea leaves can also be damaged. This can make the leaves brown or crimson at the edges. Your plant may recover from severe sunburn depending on how severe the damage was. It may not be capable of recovering from extreme drought.

3. Despite being watered daily during the heatwave, my red currant leaves were curled.

Red currant plants prefer partial shade or protection from the sun. After a few days they will likely start to show signs and symptoms of sunburn. The plant will gradually shed the damaged leaves as it grows new ones, as long as it didn’t get too dry. The next problem to be aware is spider mites. This heat could have resulted in an explosion of pest populations and stressed plants might be affected. “sitting ducks”Infestation is possible. Red currants are more prone to mites.

stressed blueberry plant4. My blueberries grew mushy even with daily watering. How can I take care of them now?

Blueberries have a very thin and fibrous root system which makes them vulnerable to drying out, especially when they are in season. Bear fruit. Plants that are less than a year old may not recover. Prune back the plants to remove some of the top-most growth and take off this year’s berry crop to reduce the plant’s energy requirements. As a final treatment, apply kelp food to the plants. Then mulch the roots using bark, compost, and other materials. To reduce soil evaporation. You can continue to water the plant as normal and let it recover.

5. My begonias have suffered! How can I help my begonias recover?

Begonias find this weather difficult! They are so sensitive to rotting when they get too much water, but can’t stand intense sun either. If they have been scorched, it’s best to cut back the leaves that look more than 50% damaged and remove the flowers to help the plant recover with less of a burden. You can give them a diluted, organic liquid fertilizer but ensure they are well-hydrated before you give them. If possible, provide shade during the hottest hours of the day. It is possible for them to be replaced if they are permanently wilted by an accidental overwatering.

6. I watered the heck out of my perennial every day, but it’s still drooping. It will get better.

When we went out in the heat yesterday, we were able to witness many mature landscape plants melting, even the stubbornest lavender. Partially welting refers to a technique plants use to preserve water and reduce moisture loss when exposed to intense sunlight. Even if the plants have been well hydrated, this can still be done. Most plants will recover completely after the sun sets, or when they are shaded with no additional water. The lavender was again perfect this morning!

7. My cucumber plant is now wilting to a third. Is it possible to bring it back?

Two thirds of the plant might be wilted, or damaged. There is still time to replant the plant during the growing season. You can still grow cucumbers if you plant seeds directly in the ground.

8. My hibiscus was charred to a crisp. However, the stems remain intact! Is it salvageable?

Your hibiscus can recover, but it will likely drop most the damaged leaves, stop any flower development and look sad for awhile. You can fertilize it, and trim the most unattractive leaves. You can continue to water it if it has less foliage.

sunburned weigela plant9. My weigela is rough. It’s in a large pot and gets afternoon sun. The sun shines relentlessly on a large tree that used to provide shade but was felled by icestorm damage. It is possible to trim the brown stems of the tree and plant it in ground.

It appears that the weigela was too dried and burned. It can recover, but it may be better to place it in the ground. You can trim it down by 1/3. It won’t get flowers this year if the plant hasn’t bloomed yet. Planting techniques for hot weather. Temporary shade is available for the first two weeks following transplantation. For those two weeks, water deeply every 2 days. Then, you can begin to back off 1-2 day between waterings each week.

10. All new growth on my tomato plant is fried. What should I do next?

We want tomatoes to ripen in summer heat. However, prolonged temperatures above 95 can cause fruit set problems and even sunburn. Here are some of my tomato recipes Plants that were already in placeFor less than a month, my tomato plants showed signs of wilting and damage. All my tomato cages were covered in shade cloth. The wind blew the shade cloth off one plant and it is now about one third burned. Yesterday was the hottest part of the day, and all my tomato plants were in complete wilt. Only one of my tomato plants seems to have suffered permanent damage to their top-most, new growth. I removed the wilted. Tips from my tomato plantsI gave them a light liquid Kelp food feeding. This will help plants recover from stress and increase potassium levels. Your plants will recover in a matter of days if you do exactly the same.

11. My Daphne burkwoodii had sunburned leaves. Do I trim them or let them rot naturally in my garden?

Sunburned leaves will eventually fall off on their own, but you could remove any leaves that have more than 50% damage now to improve the plant’s overall look. To encourage new growth, fertilize your plant.

stressed container lupine12. Some of my Lupines that are newer are starting to wilt. Flowers are also becoming fried. What can I do for my lupines to survive?

It sounds like your Lupine plants were planted new this year. New plants are more susceptible to extreme heat and sun. Plants in flower can make stress worse. It is better to give your plants an occasional deep soak than to water them daily. Mulch of at most 2-3 inches can help retain soil moisture and reduce evaporation. You might need reduce your flower stock or some of your crispy leaves. After that, fertilize lightly to allow it to grow.

13. My new trees or perennials still have their nursery pots. Do I wait for fall before I plant?

It depends on how much you have. Plants are in your gardenThe size of your project, how much sun exposure, and your summer plans will all affect the cost. Some people prefer to plant their plants in containers while others may transplant smaller plants into larger pots. They will still need watering until they are established. It may be a good idea if you have a small area that can provide shade in extreme heat to plant right away. These are the guidelines you should follow Hot weather gardening steps.

stressed knockout rose plant14. Despite watering every morning during this heatwave, my knockout roses remain fried.

Your knockout roses may not have received the right watering. They might have been sunburned despite your best efforts to water them. You can trim the plant to remove damaged areas. Even if the plant is cut very hard, it will recover and bloom within six weeks. That will still leave you with several months to enjoy this year’s flowers!

15. Are you more likely to water during the heatwaves than during the day?

Containers may require more attention depending on the size of their containers and their sun exposure. It is best to water your plants in the morning so they are well hydrated. It is better for your in-ground plants to get a deep soak every few day than to give them only light watering. Mulch containers and other plants to help reduce moisture evaporation.

16. Can I get severe sunburn from conifers or pines (evergreens)?

Severely burned conifers and other evergreens may need to be removed or replanted; they do not recover easily and will show their damage for many years (they don’t drop leaves each season). You can use light pruning depending on the area that needs to be removed. However, it is important not to cut into the bare branches as many conifers won’t regrow from old wood.

17. Is there something you can do to make potted flowers feel fresh and dry? I’ve been watering!

Potted plants that are completely dried out and crispy could either just have gotten fried by the sun’s intensity or have potentially been overwatered. Sun-scorched pots should be cut back, fertilized, and replanted. They will recover over time. It is possible to plant the roots in the ground. Root rot can be fatal. Root rot is often fatal. Root rot can lead to plants showing signs of stress such as wilting and wilting if they are left wet. Should we have this kind of extreme heat again, it’s best to move containers to a shaded location or even inside. To protect them, you can use tomato cages that are covered with shade cloth or bamboo stakes. To shade the noon sun, place them in each pot.

sunburned nandina plant18. My nandina got a little burnt. It’s not in terrible shape, just some of its upper leaves turned brown. I thought I would just trim those brown leaves. Any ideas?

The nandina just got burned. The worst leaves will eventually drop, but the plant can recover. If you don’t want to wait, you can trim them yourself. Use a light, all-purpose fertilizer to encourage new growth.

19. My fiddle-leaf fig got too hot after a power outage. It still has some leaves.

FLF are sensitive (and drama-kings!) Temperature changes are a concern for FLF. Pick up the pot to feel how heavy the plant is; if heavy, don’t water it, but give it a nice thorough soaking if it’s light. Lightly spray the leaves with Joyful dirt fertilizer and give them a light watering. Since my Blinds and curtainsMy plants struggled to find light when the doors were closed. I’ve added a few LED grow lights to some of the darkest rooms to help them out.

20. My monstera was accidentally left outside and is now being burned. What should I do next. Is it RIP?

Ouch! It’s likely that your monstera had a lot fun with its large, tender leaves. It’s likely that you caught it outside before the scorching sun set in. You have probably already given it a good drink and trimmed off the worst looking leaves; that’s about all you can do right now, but there is always hope where plants are concerned. Be careful not to overwater after removing some of its foliage. Joyful Dirt contains beneficial microbes that will help in recovery. It should be fertilized the next time it is wet. If your plant’s crown has not been damaged by the sun, it should be capable to produce new leaves quickly to restore its former glory in a few months.
