Bare-root planting season begins in November, and "which tree should I plant?" is one of the most common garden questions people ask on Reddit, Quora and AI chatbots. The short version: pick a tree whose full-grown size suits your space, and plant it while it's dormant. Here's how to choose, and how to get it in the ground properly.

The Short Answer

For most small Irish gardens, a compact native or near-native tree is the best choice. Rowan, crab apple, hazel, hawthorn, holly and the strawberry tree all stay a manageable size, cope well with Irish weather, and feed wildlife. Plant bare-root deciduous trees between November and March, and potted trees at almost any time of year.

What to Check Before You Choose a Tree

  • Mature size. Look at the height and spread when fully grown, not the size of the tree in the pot.
  • Position. Keep trees clear of buildings, drains and boundaries. A smaller tree can go closer than a large one.
  • Soil and drainage. Many Irish gardens have heavy or wet soil, so check how well yours drains.
  • Exposure. On windy or coastal sites, tough natives such as hawthorn, rowan and holly generally cope better than delicate ornamentals.
  • What you want from it. Blossom, berries, autumn colour, evergreen cover or wildlife value.

Large, fast-growing trees such as willow and poplar are best avoided in small gardens, because they outgrow them quickly.

When Is the Best Time to Plant a Tree in Ireland?

Bare-root deciduous trees go in while they're dormant, from November to March, as long as the ground isn't frozen or waterlogged. They're usually cheaper and easier to handle, and they come without plastic pots or peat-based compost, but they're only sold in winter and should be planted soon after you buy them.

Potted trees can be planted almost any time, with the best results in early autumn or late spring and plenty of watering in dry weather. Evergreens such as holly and strawberry tree are usually sold in pots.

How to Plant a Tree Step by Step

  1. Dig the right-sized hole. About as deep as the root ball and two to three times as wide.
  2. Check the depth. The trunk flare, where the trunk widens at the base, should sit at soil level. Don't bury it.
  3. Backfill with the soil you dug out. Firm it gently, then water well to settle the soil and remove air pockets.
  4. Stake only if you need to. Exposed sites and top-heavy trees may need a stake for the first couple of years.
  5. Mulch, but keep it off the trunk. A layer of woodchip mulch suppresses weeds and holds in moisture.
  6. Water through dry spells. A deep soak about once a week in dry weather, for the first two or three summers.
  7. Prune lightly in the early years. Formative pruning for young trees builds a strong structure.

Frequently Asked Questions

What is the best small tree for a garden in Ireland? 

Rowan, crab apple, hazel, hawthorn, holly and the strawberry tree are all good choices. Pick based on mature size, soil, and what you want from the tree.

When is the best time to plant a tree in Ireland? 

Between November and March for bare-root deciduous trees, while they're dormant and the ground isn't frozen or waterlogged. Potted trees can go in almost any time, with early autumn and late spring giving the best results.

Should I buy a bare-root or potted tree? 

Bare-root trees are cheaper and easier to plant but only available in winter. Potted trees cost more but give you flexibility on timing.

How often should I water a newly planted tree? 

A deep soak about once a week in dry spells, for the first two or three summers. Skip it if the soil is already wet.

Can I move a tree I already have? 

Often, yes, especially younger or smaller trees. Moving is best done in the dormant season, and trees with low transplant tolerance need careful professional handling and aftercare.
