how can i deter intruders using natural planting only?

Answer 1

Hawthorn interplanted with wild rose.
For shorter hedges (up to 4 foot) Quince 'Crimson and Gold' can be trained to be bushy and has hideous spikes (that even our builders shunned). In bloom now.
For a difficult remote corner -Blackthorn - but this will send up extra shoots and spread into a thicket.
For over a shed - a climbing rose 'New Dawn' is prolific producing most branches and vigourous growth.
I also liked the look of the razor rose where the thorns are like blades up the stems, but I forget the name and haven't tried it myself.

Answer 2

For a garden, plants lots of garlic all around the edge, through the middle, and everywhere else. Garlic really repels intruders from a garden. For your property, firethorn or pyrocanthia grows quickly and attracts Cardinals if you are in the right part of the country. It grows quickly but plant where you never want to prune or cut back the bush. You will need a suit of armor and this is no joke. Pruning this bush will tear you apart. I use maple leaf viburnum, highbush cranberry, lilac, and hazelnut. The hazelnuts grow slowly and attract squirrels but I'd rather have them eat the hazelnuts than my veggies. Sometimes what you plant is a tradeoff. Give them something else to snack on that they like and place these bushes, shrubs, etc away from what you want protected. Winterberry is also a great bush and so are rhododendrons. I could give you a better answer if I knew what part of the country you lived in. I live in Northern Michigan and these are the plants that thrive in my area. Do not plant gooseberry or currant if you live around pine trees. These plants carry a virus that kills pine trees.

Answer 3

The best way would be to plant thorn bearing shrubs like Berberis, Gorse, Holly or even the odd Rambling rose or 2,
which you can buy from any good garden centre. Plant them now so that they have a long growing season, they wont take long to double in size.
Good luck.

Answer 4

anything with barbs is good like hawthorn.berbarus Rosa. the denser and spikier the better. and these are. Even bramble as it grabs any material even skin quite well even though it isnt a tall plant, but next to other shrubs ar trees it will grow up within them. mix it with other spikey shrubs and you will have a bstard of a defence! I've tried cutting through hawthorn and bramble patches with a chainsaw as is my job as a forestry worker and i can tell you its bloody hard work to move through it.

Answer 5

Holly, Osmanthus, rosa rugosa, chaenomoles, hawthorn, pyracantha. Of course there are thistles and stinging nettles but they don't offer year round protection like the others.

Of all the above I would be most deterred by the rugosa roses - they are lethal - but prettiest.

Answer 6

This all depends on where you live and what you can plant. In general though, very dense plants shrubs work well, as do plants with thorns and plants that have drier feeling (and therefore noisy) leaves.

Answer 7

Gooseberry and Blackcurrant bushes as they have spikes on, it depends on how clever the intruder is as if they want to get in they will, sorry but very true, Good luck.

Answer 8

Hawthorn, Rosa regosa, Pyracantha, Dog rose, Holly all have spikes.

Answer 9

Yes you can and the best shrub is Berberis the ones with 2in
spikes I don't know how you spell it but it sounds like Julei

Answer 10

Holly is really good as it is an ever green, has many sharp points and looks nice.
