I was wondering how late I would be able to plant Herniaria glabra plugs? Would it be ok if they were planted in mid September?
Late spring or early summer is recommend. You can plant out now, but make sure you provide water to allow the plants to become established before winter.
Could you please advise if this plant is available in Perth WA
We cannot recommend specific retailers. However, you will be able to find seeds of this plant through online retailers, and possibly by asking around at local gardening stores.
I have two dogs that love to run around like lunatics, and in doing so, killed all the grass, weeds, whatever was green and growing in my yard. I have tried several types of grass seed, but none hold up to the abuse. I live in Central New Jersey, and am looking for some suggestions as to how to get something growing back there. When they run around now, it looks like the dust bowl from the 1930's.
There is one option that I could recommend. This plant can withstand foot traffic, as well as drought. Another plus is that it is completely maintenance free.
Herniaria can be the perfect substitute for this area. This article will give you more information on the plant: https://www.gardeningknowhow.com/lawn-care/lawn-substitutes/green-carpet-lawn/herniaria-green-carpet.htm
If rupturewort isn't safe for cats , would you please recommend a similar ground cover for a lawn substitute in Florida ? Thanks.
I didn't find much about rupturewort, except that it is considered weedy and didn't fare too well in a groundcover test. The ASPCA has a good list of toxic and non toxic plants and it isn't listed there either. I did find it in a UK publication that said it was toxic.
Here are some other options. If you find one you like, look it up on the ASPCA website: https://www.aspca.org/pet-care/animal-poison-control/toxic-and-non-toxic-plants
