Planting in Raised Beds
I grow vegetables both in the ground and in raised beds and plant them at similar distances in both. I generally squeeze my plants a bit closer together than they are supposed to be simply because I am greedy and want to make the most of every inch of space! As a general guide, the closer you plant your veg, the smaller your crop will be. Vegetables that are going to be in the soil for a long period of time, such as potatoes and brassicas really need to have plenty of room and shouldn’t be squeezed in. But
short term crops such as salads, carrots, beetroot, can be sown close together. You can then thin out later and eat the thinnings as baby veg. The depth of the beds will affect vegetables such as parsnips and carrots where root space is beneficial.
You can certainly use your beds as composters whilst waiting to grow vegetables in them, if you have small deep raised beds. A shallow raised bed may not rot down your material as it needs to get nice and hot in
the middle to aid the composting process. You may also want to get growing straight away. There are plenty of winter salads and veg that can be sown in the Autumn - mustard greens, winter lettuce, garlic, onions and spinach to name just a few.
Good luck with your new raised bed project. Please let me know if I can be of any further help.
