What Small Trees Can I Plant Close to My Home?

“Is there a type of ornamental tree that I can plant within 6 feet of my house (in zone 5)?” Amy of Grand Rapids, Michigan

Answer: Aside from being attractive and suited to your garden and area, any tree that you choose must be compact and have a root system that is somewhat shallow. Here are five selections that are both beautiful, compact, and native.

  1. Lavender Twist® Weeping Redbud (Cercis canadensis ‘Covey’): This small tree reaches between 8-12 feet when fully mature, but its weeping crown maintains a tidy, compact appearance. Redbuds are native to eastern North America and have beautiful spring flowers of purplish-red. Grow this one in full sun and well-drained fertile soil.
  2. Spring Glory® Serviceberry (Amelanchier canadensis ‘Sprizam’): White spring blooms, edible summer fruits that attract birds, and orange-red fall leaves make this an outstanding 12-foot small tree for home gardens. Grow this one in full to partial sun. 
  3. Golden Shadows® Pagoda Dogwood (Cornus alternifoliaWstackman’)The gold and green foliage of this 10- to 12-foot variegated dogwood will light up any partially shaded location around the home. 
  4. Fringe Tree (Chionanthus virginicus): Loads of delicate, fringed, fragrant ivory flowers in spring make this small tree an excellent specimen to plant near a home. Mature specimens may reach 12 to 20 feet, so this is on the larger end of what you can plant close to the home. Full to partial sun is preferred.
  5. Blue Arrow Juniper (Juniperus scopulorum ‘Blue Arrow’): Here’s an evergreen option that hails from Colorado. It has tidy blue-green foliage and a narrow, upright habit. Trees reach just 12 feet at maturity. Full sun is required.

Should I Trellis or Stake My Zucchini?

“Should zucchini be staked up?” Question from Rhonda of Opelousas, Louisiana

Answer: If you have space, you can let vining zucchini ramble on the ground, and they will produce and perform beautifully. They can ramble as far as 6-10 feet, though, so space is essential. Training them up a strong trellis is another option, which will save space and make harvest easier. But, if you lack space and prefer a tidier garden, I recommend planting bush zucchini. These reach just 3 to 4 feet across, depending on the variety.

Best Bush Zucchini Varieties

I love bush zucchini and have grown quite a few that I really liked. Here are my three favorites.

Astia‘: The plants are so compact that they are good for container gardening, and zucchini production is good.

‘Eight Ball’: Lots of cute, round, flavorful zucchinis are produced on small, bush-sized plants.

‘Green Machine’: If you are looking for classic, green zucchini on small, very disease-resistant plants then this is the variety for you. It is very fast-yielding, producing from just 45 to 50 days after planting, and it is very reliable.

I hope that this information helps!

Happy zucchini growing,

Ginkgos Large and Small

In Portland, Oregon, Ginkgo biloba trees line the streets in an area called Park Blocks. These magnificent trees were planted years ago and today reach a height of perhaps 100 feet.  The Ginkgo is an excellent choice for a large street tree when taking into consideration the ultimate growth expected.  (Large tree lawns are a must.) They do not seem to be bothered by insects or diseases, are tolerant of air pollution and most soil conditions, and they provide shade in the summer and beautiful golden fall leaf color in the autumn.

Ginkgo History

An allee of ginkgos creates a spectacular fall display.

I have long been fascinated by these historic trees and marvel at their survival instincts.  Ginkgo fossils exist dating to over 270 million years old. At one time they were thought to have grown worldwide, but presently, remnant populations were found to only exist in China and Japan. Throughout Asia, these trees were revered as fixtures in temple gardens and Buddhist monasteries.

Ginkgo trees are monoecious, a technical term meaning that separate trees have either just male or just female flowers. It may take a tree 20 years or more before the flowers develop.  When purchasing a Ginkgo, select male plants, (grafted or grown from cuttings), because female trees produce messy, fleshy, ill-smelling fruit. In Asia, they use the fruits of the female trees for medicinal purposes, but they are not of value to most homeowners.

Ginkgo Size

Many ginkgo varieties have narrow, upright habits and no messy fruit.

There are several lovely large- to medium-sized ginkgo varieties. Most have been chosen for their unique, appealing growth habits in addition to robust growth and vigor. Those used as landscape trees are always seedless males. Two of the better available selections include the narrowly columnar ‘Princeton Sentry’, which only reaches 40 feet by 15 feet, and the excellent street tree ‘Magyar’, which reaches 50 feet x 25 feet and has a narrowly pyramidal shape with branches that curve upwards.

In my garden, I do not have space for a 100-foot or even a 40-foot tree. Most homeowners do not.  However, due to recent ginkgo introductions, there are some cultivars that I can and do grow.  Sometimes these are sold as being compact or “dwarf,” but it appears that the word dwarf often refers to a slow rate of growth rather than a small ultimate size. The plants might not be “dwarf” as we perceive the word to mean.  I have been growing these new dwarf cultivars in pots and have them throughout my garden.  With their slow rate of growth–even slower in a pot–they are easy to manage, and some selective pruning will keep them at the size that I want. (Ginkgos are classic trees for bonsai, so they are amenable to hard pruning.)


Dwarf Ginkgos

At the top of my dwarf ginkgo list would be the variety ‘Majestic Butterfly’.  It is the first dwarf that I purchased, and it continually attracts the most attention from visitors.  The annual rate of growth is considered 5-7 inches, so it has been very manageable.  The outstanding feature of this ginkgo is the striped green and yellow variegation on the leaves, though the color can be variable. Sometimes an all-green branch will pop up, but as it goes through the season, the variegation will appear.

Another favorite isMarieken’.  It was discovered as a sport mutation in Holland in 1995 and is now in the retail trade.  In my garden, it has a semi-prostrate growth habit.  I have pruned it in such a way to encourage this habit, and it is now a spreading shrub of about 2 feet high and 6 feet wide.  The leaves have wavy ruffled edges and turn brilliant gold in the fall.

The dwarf ginkgo ‘Mariken’ is a bushy, spreading beauty.

The ginkgo ‘Jade Butterfly’ has proven to be quite popular with gardeners and should be readily available at nurseries.  It has dark green leaves that look similar to the wings of a butterfly.  It is another excellent ginkgo for a pot, and the unusual looking leaves draw much attention.  As it matures, it develops a shrubby, vase-shaped habit.

The Ginkgo’s Legacy

Ginkgos have long been used for bonsai and can withstand the harshest treatment.

With fossils dating the ginkgo back millions of years, the endurance and survival of the ginkgo was ultimately tested when they dropped the atomic bomb on Hiroshima in 1945.  Within days after the explosion, three Ginkgo trees sprouted new leaves.  These trees were the closest survivors to ground zero after the atomic blast.  Today they are part of the Hiroshima Peace Memorial Museum, and former Director Akihiro Takahashi summed it best when he declared that the ginkgos “expressed the endurance of hope, the need for peace and reconciliation.”
