I moved in a new house recently and my housemates have a little garden very well designed, which receive plenty of sun during the entire day and which also have some shade under a cherry tree. There are basically 3 flowerbeds (50x250cm each). Unfortunately my housemates are absolutely not interested in gardening, so I had to remove all the weeds they let grow in these flowerbeds which now are completely nude.
I would like to take advantage of this little garden which could be really pleasant, and I really like growing things! But the problem is that I am leaving the house at the end of July. So I would like to know if you think it is possible to grow some flowers and other plants from seed in this period of time, very short indeed. I do not need to see all the plants blooming, but at least some leaves would make me very happy! So, as I do not want to grow only marigolds, I would be very happy if you could give me advices.
Thank you very much!
