I love when you use" a lot of words for that", I find it very helpful.
Q: You've mentioned the work birds do in the garden, what about toads, frogs, skinks, lizards, snakes etc. Are their presence a good sign?
If you mix sand to clay, you will have some nice concrete.
Follow up to the landscape fabric removal question. If you do remove the fabric, should you do anything to your soil underneath by way of amendments? Or, just recover it with the mulch and move on?
Hi Jim and Steph,
Regarding the weekly planner, I am in zone 5b. Would the weekly planner be useful? I am thinking probably not due to your now zone 8a. Thank you.
Man do I ever look forward to these weekly Q&A vids! Just tuning in. 😊 8a / W. TN ☀️ PS: I have way too much turf! 3.3 rural, hilly acres.
So sorry I fussed about the raised garden info. It was mostly the rave accolades about in-ground gardening… As a gardener, I aim to "grow" a thicker skin, and you aren't gonna get rid of me that easy. 😊 Thank You Jim, for ALL the great info I am learning from you.
I put a beach umbrella over any new plants that i put into the ground at this time of year for a couple of weeks (eastern NC zone 8. It seems to help. I also prune them back by 1/3 which seems to help (thanks Jim & Stephany) for teaching me that!
I don't think you need to apologize for your raised bed comments. I think they are mostly a trendy aesthetic, not for a logical purpose that you mentioned. My daughter has a couple that do not produce and are very expensive to fill with soil and amendments. And there's no reason for her to have any, as she has perfectly good ground to dig and plant in. But the raised beds look tidy and cool, I guess. And I agree with you, that as someone who has planted tomatoes in the ground and now in huge grow bags on my deck (that is the only full sun left on my property), though the tomatoes taste better than the grocery store, they don't come close to the ones I used to grow in the ground, and I'm sure the nutrients are lacking as well.
What type of mosquito repellent do you use? The bats, dragonflies and mosquito dunks can’t keep up with them this year in zone 8A Atlanta.
First I want to say thanks so much for sharing your decades of knowledge with everyone via YouTube. I’ve been faithfully watching for a year now, and always enjoy your videos. Next, is a request that I hope you’ll be willing to entertain. Could you please convince Buddy Lee to do for peonies what he did for azaleas? “Hydrangea what? Rose who?” That will be the mantra if he can get these gorgeous, fragrant plants to rebloom. Just a simple little request, right?😂
Thanks again for all that you do.
Zone 7b,
Middle TN
I really enjoy your videos. They are almost akin to the click and clack NPR shows I listened to back in the day. Good times.
Would you please tell us why Amethyst Gems Redbud (all Redbuds??) is evidently "Restricted" from Utah, etc.
It's incredibly difficult to get an answer to that question on the internet. I ask, and simply receive a ton of sellers from whom I can purchase this beauty.
It appears all Redbuds are Restricted from Utah +??
Why is that, please?
WHAT WOULD BE A GOOD REPLACEMENT in UTAH?
I'm in 8b, St George UT; 100°F arid themps 5 continuous months/year. We are in a leg of the Mojave Desert. Water shortage is something that's being hinted at — St George has many golf courses and hospitality around golfing. TURF.
regarding the soppy bottom stump how about planting something that likes wet feet.
For the pnw fried panicle hydrangea viewer: I had three newly planted fry to a crisp in heat dome. I dug them and moved them to a shady then a part sun area to take the pressure off. I won’t lie, they still showed the effects the following year. The two Candy Apple are still behind where I expected them to be, but the Strawberry Shake is fabulous this year.
Great info! Thanks Jim!
Your mentioned that having some low spreading plants can help keep the roots of tall plants cool. My two biggest weed problems are: Creeping Cinderella-weed (Asteraceae) and Green Creeping Spurge (euphorbiaceae). After spending time in the Houston sun (Zone 9a) pulling these weeds, I wondered if I should just leave them and let them “cool the roots” of my abellias, azaleas and loropetalums?
Jim. do all flower beds need to be completely filled with plants to suppress weeds or do you prefer space between your plants, so air can circulate?
I kept getting distracted by your beautiful garden, Jim! Thanks for all your gardening tips.
Zone 8a Milton Florida, my amaryllis bloomed in spring. Now there's massive foliage growth, will they bloom again this year?
Great video! One thing I'm struggling with especially this summer is yellow leaves on plants. Not sure how to distinguish between overwatering, underwatering, heat stress, nutrient deficiencies, etc. I'm in Georgia, zone 8a. We planted some little lime hydrangeas in the spring and they are blooming and not wilting in the sun, but have more yellow leaves than some of my other hydrangeas. I also struggle with my encore azaleas — never seem to get the leaves to be a lush green like when I first purchased them. They seem to be more yellow with occasional reddish coloring from time to time. What is the best way to determine what is causing this and how to fix it? Thanks!
It’s finally cooled down a bit here in SETN zone 7b. For the past few years we’ve been on a schedule. Once a week or every three days if it’s very hot without rain. My plants have really suffered this summer and I wonder if you have an opinion on the UV index and its effect on plants? I noticed when the UV index is highest it bothers my camellia. It’s actually gotten a sunburn on a few of the leaves.
You mentioned hydrangeas knowing what to do. My panicle hydrangeas are the only thing that hasn’t been sad this summer. I agree they definitely know what they’re doing. Last year they wilted in the evening but they’re standing up to the heat. They’re the stars of the garden this summer.
We live in Fort Worth with a full sun garden, so this is hell season. Grasshoppers are defolating many of our plants. I have been handpicking them but for evryone I kill there are 30 more. Any advice will be deeply appreciated. Your station has been a great resource, and your garden is looking great. Thank you.
42:38 Thank you Jim for answering my questions about battling poison ivy and honeysuckle. This is exactly the kind of advice I needed. I was too reluctant to spray but you are right, this wacking back seems never ending. As you said, I need to take care of this and start planting. I'm gonna throw the world at it! Golden advice, exactly the encouragement I needed!
😊 another great video- Thanks Jim
Love the brick patio against the green of the plants
Zone 7a Richmond, Va. The 4 yr old front foundation boxwoods did not get pruned this year. Rain is causing the branches to fan out from the middle. Is it too late to take off some of that weight? Also, have you ever seen a Daphne odora drop most of its leaves in heat like this and then start showing new green growth at the tips?
Jim, we’re building a garden on an island in Maine, zone 5. It’s difficult to get material over by ferry. What are your thoughts on using seaweed as mulch or compost?
Hi Jim. Living in France, 7b. Herbicides (like glyphosate) are strictly Forbidden here, except for agriculture. I have a terrible bindweed issue in my woodchips mulched beds where shrubs and perenials are growing. I keep pulling them out but taking the roots out is impossible (heavely rocky clay soil) Is there any other method I can get rid of them?
My small garden was solid red clay which we amended with compost and topsoil before I started my problem is that it is a slope and the clay area above it was not amended. The bank above solid clay also washes down directly into my garden. What can I use to hold that bank in place? Also, my garden, is shade next to the house and gradually gets more sun in the front. I actually have ferns in the back and rudbeckia towards the front. The garden is 5 ft by 25 and in Weaverville North Carolina.
Jim, i am thinking of using a musashino zelkova to fill a space between two crape myrtles. My concern is how it will handle direct afternoon sun of 6+ hours. Im in central valley Ca zone 9b. The sun is brutal. My myrtles handle it no problem
Jim- yes I'd be very interested to know how the hort industry is trying to educate the public regarding improved cvs of historically maligned plants. I'm not so sure it's been a success so far. For ex I have observed customers shaming other customers in big box store nurseries for having nandinas in their carts because "nandinas spread everywhere, plus they poison millions of unsuspecting birds each year". Information thats on most gardening websites unfortunately. To most, a nandina is a nandina and is "evil" even if they're aware of the new sterile or essentially sterile cvs.

❤hello, I hope 🙏 for the rain 🌧 🙏.
Hi Jim and Stephanie,
I have a propagated limb from an Osmanthus tea olive shrub and a White Wedding hydrangea.
A limb from each plant has been in its own pot for a year.
Please advise me as to when I should cut it from the mother plant and plant in the ground.
Thank you so much,
Sandy. Zone 8 a in Chattanooga, Tennessee.
When I water gardenia its leaves turn black from tips especially the new ones. Have you experienced this? I used simple river soil bought from nursery.
We are in zone 7b, Petersburg, VA. Looking for small shrubs or perennials for large containers in full sun. Any suggestions? Thanks
So I finally gave in and planted vinca in a container because you kept raving about it. I'm not a fan of it but I thought I would give it a shot. Unfortunately something is eating the flowers. Can I use Neem oil?
Question. I have flower beds about 12 ft from a large maple tree. The tree takes all the water and the soil around the plants is dry even with frequent watering. Would it be beneficial to water the maple with a sprinkler? Would it take less water around the other plants?
QUESTION: I recently discovered your channel and just love it. You are so knowledgeable. Thank you for sharing. I’m newly retired and have more time and really want make my yard a garden sanctuary for myself and friends. My question is, if I were to plan intensely as you have, what would happen to the area if I were to not be able to garden anymore. Would the yard become a hot mess quickly that would actually decrease the properties value or will yards similiar to yours keep thriving and looking good for years? Thanks
Hello! Thanks as always for your super-helpful and entertaining videos. We're in NYC, zone 7b, and have a couple of questions for your consideration. First, why do our tomatoes often get black spots? Last year, we had plum tomatoes that had black bottoms. This year, small slicing tomatoes have black spots on their sides. Not all of them, just a few so far. Could I be over or underwatering? Not enough fertilizer? Or maybe there is some fungus in our soil?
Second, we have a white wedding hydrangea that is blooming beautifully, but some of the stems have started to droop. It is a small plant (planted in April) with large blooms. Do you think the stems will strengthen as the plant matures in coming years? Should I prune the drooping stems now or tie the plant up to hold them up a bit?
Loving the detailed garden tour videos!!
Texas had months of triple digit temps the last two Summers. This Summer, we seem to be getting a break.
Great questions, great answers.
Thank you, Jim. 😊
How can improve the soil of my already established perennial bed without digging out everything?
Hey Jim!! You must watch Monday's video of Visit Our Garden Q and A with Robbie. He mentions how he met you at Cultivate and he speaks so very highly of you. 😊He's a sweet man.
