At least many of the classic Spring bulbs that we plant each fall for an explosion
of color next year, such as crocuses, daffodils, muscari (grape hyacinths) and alliums
aren’t on squirrel menus!

Use jalapeno pepper as a deterrent against squirrels digging, by scattering it around
planting holes and the soil surface. Do this regularly until the problem has been
addressed.

## Natural Deterrents

Squirrels and chipmunks may be cute, but they can also damage or devour tulip and
crocus bulbs, leading to serious crop failure. There are a range of inexpensive,
natural deterrents to protect plants from these creatures – physical barriers designed
to block access as well as ingredient switches designed to ward them away.

Most techniques for keeping squirrels at bay involve repelling pests with scent,
heat, fumes or oils. Many plants give off natural odors or volatile oils that deter
insects; concoctions from garlic, tobacco and rhubarb are effective too; other natural
deterrents include chillies, kerosene and salt as effective deterrents as are oily
substances such as mineral oil, vegetable oils or insect-control blends that suffocate
soft-bodied insects such as mineral oil or insect-control blends suffocated soft-
bodied insects with mineral oil or vegetable oils as other natural deterrents; all
natural and deterritories against squirrels are effective.

To protect a newly planted bulb bed, simply form a cage out of chicken wire or hardware
cloth around its planting hole and cover it with either shredded leaves or bark 
mulch to keep squirrels and other rodents from digging up the bulbs. It can also
be used as an enclosure around new plants, shrubs and trees as well as when growing
lilyturfs with spiked foliage such as tulips that require long roots before flowering
begins.

Crushed garlic can help deter squirrels and other garden invaders, as can bone meal
used to mask the bulb’s scent, available at most gardening stores. Hen manure also
acts as a deterrent against rodents while citrus can add scent-deterring properties
through flowers, plant clippings or chopped peels that emit citrus fragrance into
your garden space. Coffee grounds may also prove effective as natural fertilizers
as they decompose in soil over time.

If your burrowing animal problem persists, try installing a temporary fence made
of chicken wire with lengths of fencing wire bent into an “L” shape buried just 
under the soil. It should stand about 90cm (3ft), be at least 20cm (8″) high and
at least 20cm (8″) deep buried. Camphor repels opossums when mixed with oil for 
use as spray or rub on tree trunks and other areas – it may even help!

## Physical Barriers

Squirrels dig up bulbs in search of food during winter. Your newly planted bulbs
offer them an easy meal full of carbohydrates and starch; their sweet, juicy scent
attracts them too – especially those of tulips, crocuses and hyacinths which make
their way onto their menu! A deterrent may keep these pesky creatures at bay so 
your spring colors remain intact!

One physical barrier is wire mesh such as chicken wire or hardware cloth laid over
soil before backfilling. It’s simple and quick to set up; yet doesn’t prevent roots
from emerging; then just cover with mulch to complete its coverage. Or you could
buy or make bulb cages made out of half-inch hardware cloth hats with holes cut 
out for each bulb and planted before backfilling – another effective strategy against
tunneling animals like voles!

Just one more simple trick to try: planting bulbs deeper than normal (8-10 inches/
25-25 cm). This extra layer makes the bulbs harder for squirrels to reach when watered
after planting and compacts down dirt more effectively, making digging harder. As
an extra physical barrier, add sharp gravel or crushed oyster shells as physical
barriers – their jagged texture turns off squirrels so that they’ll avoid your garden
entirely – these materials also work great when combined with natural deterrents;
clearing physical obstacles is often enough enough to clear away mental obstructions–
good luck with clearing mental barriers as well!

## Time Your Planting

Spring blooming bulbs such as tulips, daffodils and crocus need time to establish
themselves before winter arrives; therefore it is vitally important that these seeds
are planted in autumn before a freeze hits Cincinnati conditions. Refer to your 
seed packet or consult your gardening center for specific planting times in Cincinnati
conditions.

Plant your bulbs among creeping vinca and pachysandra groundcovers or perennials
as an effective deterrent against squirrels and chipmunks digging up their stems
as soon as they begin blooming, adding early color before summer perennials come
into full bloom. This strategy may also add early color before summer perennials
take hold in full force.

Use a critter-repellent like ground red pepper on the soil surface around your bulbs
or scatter crushed oyster shells for added critter deterrence, such as ground red
pepper. These rough textures discourage digging. Alternatively, chicken wire secured
down and covered with thorny branches or mulch can keep animals away while still
allowing bulbs to grow through it – simply cover it all up later with mulch to disguise
and prevent any weed growth underneath it! Continuing composting adds organic material
back into the soil over winter by mixing green materials like kitchen scraps and
garden plants with brown materials like dried leaves to speed up decomposition processes–
avoid adding any diseased plants into pile and turn regularly to maximize effects!

## Other Tips

As we enter fall planting season, squirrels and chipmunks become increasingly hungry
as food sources diminish; as their other food sources decline further they seek 
protein-rich nuts and bulbs that will provide sustenance through winter. Luckily,
there are various easy strategies available for keeping pesky rodents away from 
precious Spring bulbs such as physical barriers or household products; using these
simple strategies you can keep tulips and crocuses where they belong!

Build a Cage – To protect the area where you plan to plant bulbs, construct a cage
from chicken wire large enough to encase it and the area where your bulbs will go.
Create holes large enough for plant roots and stems to grow through while still 
being small enough for squirrels not to gain entrance. This method may prove particularly
effective when dealing with larger spaces like vegetable gardens or flower beds.

Add a Layer of Gravel or Gritt – To deter digging, consider placing a layer of sharp
and textured gravel or grit under and around your bulbs when planting them. This
method works particularly well when placed in large spaces like raised garden beds
where access may be more limited.

Deer-repelling granules may work to repel squirrels as well, according to reports
by gardeners. Some advise sprinkling the deer-repelling granules over your soil 
surface while others suggest applying it directly where bulbs have been planted.

Plan Your Bulbs in an Isolated Location – When planting bulbs, aim for an area away
from other perennials or trees in order to divert squirrels’ attention away from
your bulbs and away from any possible harm caused by squirrels. This will prevent
their nibbling at them!

Make an impressionful display – There are various Spring bloomers that don’t attract
squirrels, such as daffodils, narcissi, grape hyacinths and alliums. Or check out
Natorp’s Spring Blaze Mix which features fully squirrel-proof bulbs!

Be sure to read your packaging’s planting depth recommendations when planting bulbs.
Too shallow planting could leave them susceptible to cold temperatures and hinder
their development; for more help on this matter consult gardening books or experts
at greenhouse or nurseries near you.
