Well sort of money saving, kinda maybe not, but could be...anyhow here is my tip thought of it today.
I have brought summer flowering plants the ones you see in packs that are tubers/bulbs etc. I intend to plant them in tubs/pots in the garden and then see where I have gaps in the garden (when the plants in the tubs are in flower) and plant them there......spent £20 today on the plants.
I just thoght it would be a good money saving tip as when you buy the plants in tubs in the Spring they can be anything like £6 a lupin and I brought 3 for £2
They are all perenials (come up every year) too
