Mulching?

I was talking to my dad about growing "tomato plants" and he said he always puts mulch around the base of them. so i googled it and found this quote on a site:

"Mulch the tomatoes for highest yields. Place a 2-3 inch layer of organic material such as compost, leaves or hay around the growing plants. Mulching helps stop weed growth and water loss from the soil."

my question is, would the same work for marijuana plants?

i just put some mulch around my plants today. they seemed to like it. it keeps em cool. the leave went erect when i put the mulch in the pots with em. it was made out of leaves and bark ect and it was outside for 3-4 months for good stuff.

so yeah i say you should it has alot of benefits

ps make sure theyres no bugs.

that ruins it

Mulching is a good technique for most plants.
Many different materials work well. It keeps the temperature of roots a little more steady, retains more moisture, and controls weeds.
I understand that bark-type muches have a tendency to use up additional nitrogen as they decompose into the soil around plant. Some growers adjust by adding a little extra nitrogen.
One of the best mulches I have tried is simply old newspapers layered around the base of plants...at least an inch or so, I just cover some of it over with soil or put rocks on it to hold in place. After the first rain it melds with the soil and controls weeds and retains moisture very well. I use this for tomato plants in very hot weather!

The newspaper idea is great. It is low tech and low cost. I have used this in several planters. Wetting the newspaper makes it much easier to work with. Be careful too many layers of paper works like a barrier restricting even air movement. Hence the usefulness in landscaping. Mulch works by holding in mositure and helping keep weeds out. It will work with pot. Just be careful not to get any mulch around the stem.

mulching with pea hay or lucerne ,and well washed seaweed someone told me to try?her garden is amazing all of her plants look great,and i will give it a go as mulching in oz helps with our hot summers so i always do.
but the above is a new one the seaweed has to be really washed first and the pea hay when it breaks down provides some nitrogen,so i will take her word,but will try it on other plants before my happy cabbage

wouldnt fine grain wood chips work well

Depends on the type of wood. Some types of wood are good because they release a chemical that is not good for plants. Like hemlock, some types of walnut and certain cedars. Every notice that hardly anything grows under an English Walnut tree?
