Grass help

Hydroseeded lawn about 5 years ago and have been gradually overseeding and using weedman. I still seem to get a lot of brown stocky blades. It is starting to get hot/dry but I'm not sure if this is just normal dormancy at all. I also seems to sharpen my mower blades twice per year and still get these edges. Blades are 5 years old as well maybe they need to be replaced. Looking for any suggestions. Large mostly fun sun, non-irrigated 30,000 sq ft lawn in Nova Scotia. Thanks!

Hi,

I have this beauty tree on the backyard and half of the branches are empty.

So dear community, how can I save this beauty ?

Thanks a lots.

First time homeowner and weeds have invaded my backyard !!!

Purchased my home in northern Alberta during winter and I got a surprise during summer ! I have all kind of weeds in my backyard and not sure how to get rid of them? Any leads ? Products to use ? Or techniques to remove them ?

Where do I begin?

I live in SW Ontario, and these two weeds (along with a few others in a minority) have taken over my lawn.

I water regularly, and have my cut height set high in an attempt to let the grass dominate, but it's not working. South grabbing front lawn, full sun.

Need help with crazy weed situation

Hello all,

We recently moved into a new built home in Alberta. We have been going back and forth with our builder on completing the grading and getting us the grading certificate. They neither have done any work or given us a date.

I cannot do any landscaping without the certificate. I am tired of waiting as the weed in the backyard has gone out of control. At this point I am ready to pay out of pocket to get rid of the weed and make it ready for the landscaping work.

This is our first home with a backyard and looking for any advice on how to get rid of these crazy weed. I also want to ensure that these do not come back once our landscaping is completed.

Thank you for your advice. Photo attached.

Fiesta killing grass

Been seeing decent results with Fiesta, but may have gone a little too hard. Increased the concentration slightly and used a surfactant. I have now killed a bunch of my actual grass. Any experience with this? Will it bounce back?

Help, how do I damage control and how do I turn this around?

First timer, I know I screwed a few things up out of the gate but I was rushed and now I’m here so hopefully I can get some advice on next steps…

Background: located in Ontario, just outside GTA.
Had my yard all torn up for a new garage build. Had free fill brought in to level the yard ( likely first mistake). Then screened top soil. This brought me to first week of June where I just wanted to get some grass so the kids had something to play on this summer. Seeded with “kickass” grass seed? From local supplier and starter fertilizer. I had a good suspicion the first big rainfall on day 3 or 4 washed away a bunch of seed. Wasn’t sure on walking all over to reseed so I waited till week 3-1/2 when I really could see the bare spots and how thin it was coming in. I was pretty anal on watering twice a day and covering all areas with extra hoses till about week 5.

I’m now headed into week 6. The photo looks dry because I held off on the watering the last 2 days as we had a huge rainfall and it seemed saturated. My bigger concern is the amount of weeds around the perimeter and lack of green grass fullness…

At this point rolling into the second week of July what should I be doing to save this if I can?

Rate my DIY!

​

I haven't ever done any landscapping work, no experience in DIY.

This trash can pad project is the first project I did work. Please rate this and feedback. I am sure its far from perfect but learnt alot during the process.

One thing still I like to work on may be is the access to the driveway. It has a slope of 6 to 7 inch.

For these pavers, i excavated almost 4 inch and added sand for levelling and then pavers. Put the lumber 4x4 treated to kind of restraint the slope and used paver base stone under the lumber base. Used galvanized spikes 12" to anchor with the ground

13 year old lawnmowing tips

I started lawnmowing in my neighborhood last month and I've been making quite some money but I wanted to know more tips

Thoughts on Weedman or other similar services

Anyone have experience with Weedman and was it worth it to you? I live in a province where certain chemicals for lawn weed control are forbidden, and so i've been using Weedman for several years. I also do a lot of additional work (lime twice per year (east coast), use WedBGone, overseed, etc.). My lawn is okay, but far from perfect, and I spend a lot on it when you count both Weedman plus my own separate endeavours to maintain my lawn.

Is Weedman fertilizer and weed cont worth it in your opinion?

Advice on getting started-Alberta

I have had this house for 10 years and have only spent minimal time on my lawn. It has looked decent in years past but I feel like it’s always lacking thickness and seems to always have patches that just barely grow, especially around my rock retaining wall that faces south. I dethatched aerated this spring hoping that would help. Any tips would be much appreciated

Is this fungus?

Our southern Ontario lawn was in bad shape last summer - grubs, bare spots, and no supplemental water. The first week of May this year we had it dethatched, aerated and overseeded. We watered multiple times per day until a few weeks ago when we switched to an every other day schedule, probably 0.25 inches at a time. Admittedly we’re doing this in the evening due to work schedules. Now we’re starting to show some browning. Is this normal mid-summer dormancy behaviour (it is 35C out there right now, after all) or is our watering pattern causing a fungus problem? If so, what kind and how can we treat it? We’re in Canada so chemical options are limited. Do I just cut back on watering and risk losing the new grass? If it matters - it was fertilized/treated for weeds about 10 days ago. I don’t recall seeing this before then, but it’s also gotten much hotter since.

Dollar Spots in my new lawn (Ottawa). What can I do?

Need some advice. Detached and reseeded the entire lawn in Spring. Grass was thriving. Added some Turf Builder on Sunday and reseeded again to cover bare patches. I am located in Ottawa and it rained very heavily last 2 days. Now I see this dollar spots on the places I put the turf builder. What can I do and how bad is it?

Why does Par3 have such a loyal following?

I know Par3 concentrate is twice as strong as Killex concentrate. However, from what I read, you use 120 ml of Killex vs 60 ml of Par3 to blanket spray a 1000 square foot yard. That means the amount of active ingredients put down on the lawn is roughly the same.

Based on this, I was just wondering why does Par3 have such a loyal following? It doesn't seem to be any more effective at killing weeds or am I missing something?

Killex:
2,4-D: 95 g/L
MCPP-P: 52.52 g/L
Dicamba: 9 g/L

Par3:
2,4-D: 190 g/L
MCPP-P: 100 g/L
Dicamba: 18 g/L

Can my lawn be saved?

I killed my lawn last fall with roundup and this May I added soil and overseeded. I guess i didnt add enough seed. Some areas didnt catch properly and remained thin and weeds just took it over. What can I do now to prevent it from getting worse and have a nice lawn for next year? I try to pull by hand as much as I can but theres a lot.

Fyi no pre-emergent was sprayed this spring since I didnt want to damage new grass seeds.

Have a lot of spotted spurge, clovers, and crabgrass.

Appreciate all the help!

Someone told me it was too late to grow grass from nothing in mid june

Yes I known there are weeds. Yes I know there are bare spots. But I had nothing before, and I mean nothing.

My method was:

  1. Scalp (mow super short to get rid of whatever weeds were there)

  2. Scarify

  3. Lay 1 inch of new dirt everywhere

  4. Spread a ton of grass seed

  5. Spread starter fertilizer

  6. Water every day or let it rain if weather calls for it

This was my result in 2 weeks. I live in southern QC

Advice needed for new lawn

My backyard was in serious need of a tune up so decided to completely remove everything and install new sod. It's been exactly two weeks since it went down. Seems to be coming along fine. Some spots seem to be growing a little better than others but overall it looks pretty good. I'm in Eastern Ontario. Installed a day it was cool and then we had torrential rain the following day. It's gotten really hot as of late (45 with humidex) so I'm doing a deep soak in the morning and early evening (30 min) unless there's a storm which today was unreal. I still haven't cut it. The sod itself does not pull up anywhere I try to gently or even hard for that matter. Question for the experts:

  1. Should I be ok to cut this week/weekend and if so how short should I go?

  2. What should I do next for maintenance? Fertilizer? Any other treatments I should look into doing?

Really want to succeed here and any tips/advice is greatly appreciated.

Thanks!

This sub helped before, so I'll keep going. Located in Nova Scotia. This is a newly hydroseeded lawn (Sept 2025).

I've added some pictures to illustrate what I'm dealing with.

The lawn is a lawn only by name. It's more of a pasture. We made the seed up with a healthy amount of clover and timothy for the deer, hare and geese. They love it. They don't seem to be doing any damage either.

Questions:

  1. I've got the time and material to overseed this coming week. I was going to cut the grass, aerate, and over seed. I know the fall would be best, but is doing it now just a complete waste of time? Would I see any potential benefit? Photo A shows the bare spots we have throughout the property.

  2. Photo B......we have 6 springs on the property. They bubble to the surface all year. The surface water around here contains a lot of iron. I was wanting to put small gardens, bushes etc on those spots. Is this plausible? Or should I just ditch them into the woods?

Thanks in advance for any help!
