Portland Oregon is really a gardener's dream in terms of the plethora of plants available to grow, along with the amount of sunshine the state gets. The exception to this rule of course is in the case of a long wet spring, which can drown your plants, but other than that, Gardening in Portland offers some of the most diverse plants and interesting seasons to succeed with your garden. Oh, keep in mind that the Summer requires irrigation during the 70 day dry spell.

First, let's take a look at some problems associated with Gardening in Portland Oregon:

Leaf Mold: Leaf mold is a form of compost produced by the fungal breakdown of shrub and tree leaves, which are generally too dry, acidic, or low in nitrogen for bacterial decomposition.

Slugs: Slug is a common non-scientific word, which is often applied to any gastropod mollusk whatsoever that has a very reduced shell, a small internal shell, or no shell at all.

Moles: Moles are the majority of the members of the mammal family Talpidae in the order Soricomorpha. Although most moles burrow, some species are aquatic or semi-aquatic. Moles have cylindrical bodies covered in fur, with small or covered eyes; the ears are generally not visible.

There are community gardens in Vancouver and Portland and in the suburbs. Gardening in Portland Oregon is allowed (or even encouraged). Many people transplant from other areas just to come to Portland Oregon to garden. 

Also, container, and rooftop gardening is pretty popular in and around Portland Oregon.
