Cold Hardy Plants for the Coastal Bend

and establishment for hardiness

Last week I planted some trees in my yard.

I have sandy soil and Saint Augustine grass

I cut the grass 2x the diameter of the pot, removed the grass, and shook the soil off. turned it upside down to let the roots dry out to use as additional mulch.

For my soil I dug the hole about the depth of the soil in the pot.

Mixed about a 1/3 compost to the backfill and watered it in well to settle the soil around the tree.

Staked the tree with some nylon webbing so it would not blow over.

Put the grass around the base of the tree and mulched it with 2 to 4" of wood mulch.

Mulching is very important as it retains moisture, keeps the soil cool and as it decomposes adds organic matter and micro-organisms to the soil.

Planting a tree this time of year this way and with proper watering will get the tree well established before winter.

Planting Containerized Trees

Containerized Trees are trees that contain all of their roots in the container.

These can be planted successfully at any time of year if planted properly.

Handling Trees before Planting

Avoiding unnecessary damage and stress to trees prior to planting will ensure better success.

  • Keep the rootball moist.
  • Handle the tree by the container, not by the trunk.

Preparing the Hole and Planting the Tree

Preparing the planting area properly before planting is very important.

  • Dig the planting hole two to three times the diameter of the tree’s rootball and no deeper than the rootball itself.
  • For clay soil, plant trees one to three inches above grade. Plant trees at their original grade in sandy soil.
  • Do not put crushed stone or gravel in the bottom of the hole!
  • Carefully remove the container.
  • If roots are excessive and circling the inner walls of the pot, score the outer edge of the rootball by slightly severing or scratching to loosen the root system. Do not cut deeply into the rootball.

Backfilling the Planting Hole

Fill in the planting hole (backfill) with native soil and mix in 1/3 compost to the backfill.

Compost mixed in with sandy soil will increase the ability of the soil to retain water and nutrients. In clay soil, organic material helps to add air pockets and gives space for the roots to find oxygen.

Fertilizing

A new tree should not be fertilized for the 1st year to encourage its roots to expand out into the native soil.

Future seasons it should be fertilized out at the dripline of the tree.

Watering the New Tree

Newly planted trees should be watered in well at the time of planting to ensure air pockets are removed from the backfill material.

Generally, young plantings need an equivalent of one inch of rain per week. Newly planted trees may need to be watered two or three times a week in extremely hot, dry, windy weather because their root systems cannot take up the amount of water needed to replenish the water lost through the leaves. Watch for signs of wilting as an indicator that the tree needs water. (wilting can also be a sign of overwatering especially in clay soil) Be cautious not to overwater or the amount of oxygen in the soil will be lowered to a level that will damage roots, especially in clay soil.

Dig under the mulch a couple of inches to check the soil moisture before watering and only water when it starts to dry out.

If you have several young trees and shrubs, a drip irrigation system would be wise.

Mulching the New Tree

The secret to a thriving orchard is mulch.

New trees should be mulched using organic mulch two to four inches deep and five to six feet in diameter; keep mulch at least two inches away from the trunk of the tree. Do not mound mulch up against the trunk of the tree. You can also put cardboard underneath the mulch to discourage weeds.

The benefits of mulching are:

  • Create a weed and turf-free area.
  • Reduced plant competition for water and nutrients.
  • Regulate soil temperature and moisture.
  • Add organic matter to the soil as the mulch decomposes.

Pruning a New Fruit Tree

To produce quality fruit, fruit trees need regular pruning in their first few years to develop healthy growth and well-spaced branches, and continuous minor pruning thereafter. There are many different ways to prune fruit trees that result in good-quality trees.

When you pick up your trees at the nursery I can help you prune your tree to get it to a good start.


Staking Trees

Stake young trees sparingly and briefly when possible.

Stake trees when top-heavy or planted in windswept areas. The material used to attach the tree to the stake should be broad, smooth and somewhat elastic. Do not stake the tree too rigidly. Always allow for sway.

Growing Avocado Trees in the Coastal Bend

Avocado trees originated from rainforests where they adapted to grow in fertile black soil loose with deep organic matter and although getting lots of water this free-draining growing medium allows the root system to breathe and expand. The feeder roots are in the top 1 foot or so of soil and the taproot to 2 to 3 feet to anchor the tree. So it is important that the taproot is above the clay layer.

Avocados grow best with a soil pH of 5-7. Here at the nursery in Aransas Pass, I have sandy soil with a PH of 6.9 from the soil test I had done, slightly acid.

The Coastal Bend has both sandy well well-drained soil or heavy clay soil that does not drain well depending on what area you live in.

Heavy clay soil is not ideal for avocados, but there are a couple of options, you can plant your tree in a raised mound, in a raised garden bed, or in a large pot of amended soil to improve drainage. This method keeps the taproot out of danger and allows the feeder roots to still explore the topsoil and get the nourishment it requires without becoming waterlogged


Links to additional information on growing avocados

For the 1st year or 2 it is important to protect the green trunk and foliage from the sun and drying wind.

Selecting Fruit Trees for the Coastal Bend

Things to consider when choosing fruit trees

to fruit successfully in our climate. 

Many temperate fruit tree varieties such as apples, pears, peaches, plums, etc. don’t do well In South Texas.

Why? We live in a semi-tropical environment with a very mild winter and not a true temperate climate with a consistently cold winter.

 Fruit tree's chill hour requirements

Chill Hours - What Are They & Why Do You Need Them?

Fruit trees, such as apples, peaches, pears, plums, require a period of dormancy and the accumulation of chilling to produce flowers and fruit.

If a fruit tree is grown where winter cold is insufficient to satisfy the variety’s chilling requirement, blooming and foliation will be delayed and erratic; fruit set and fruit quality will be poor.

A chill hour is the amount of chilling received by a plant at 32 to 45 degrees F.

 

The Coastal Bend is in Hardiness Zone 9b

The minimum average temperature range is 25°F to 30°F.

The Coastal Bend on average receives 110-310 Chill hours

For plants to thrive in your geographical area, it requires matching ideal USDA Plant Hardiness Zone compatibility with the optimum amount of chill hours.


Pollination of Fruit Trees

Some types of fruit trees may be pollinated with their own pollen and are considered self-fruitful or self-pollinating. Other types of fruit trees require pollen from a different variety of the same type of fruit trees. The transfer of pollen from one variety to a different variety of the same type of tree is called cross-pollination. Cross-pollination is essential for apples, pears & most sweet cherries. Cross-pollination is not essential but does improve the number of fruit that form on other fruit trees.

Pollen is primarily transferred by honeybees.


Fruit Tree Chill Hour, Hardiness Zones & Pollination Requirements

  • Almond – 200 to 700 chill hours – Zones 5 – 9 - most require cross-pollination
  • Apple – 200 to 1200 chill hours – Zones 5 – 9 – most require cross-pollination
  • Avocado – Zones 5 – 9 – A & B types help with increased pollination, but is not required
  • Banana – Zones 4 – 11 – self-pollinating
  • Cherry – 600 to 1200 chill hours – Zones 5 – 7 – most require cross-pollination

·        Cherry, Barbados & Surinam – Zones 9b – 11 – self-pollinating

  • Citrus Trees – Zones 9 – 11 – self-pollinating
  • Figs – 100 to 500 low number of chill hours – Zones 5 – 9 – self-pollinating
  • Grapes – 100 to 500 chill hours – Zones 5 – 9 – most are self-pollinating
  • Loquat – Zones 8b – 11 – self-pollinating
  • Olives – Zones 9 – 11 – most are self-pollinating
  • Peaches – 150 to 1200 chill hours – some are self-pollinating
  • Pears – 400 to 1500 chill hours – Zones 5 – 9 – some are self-pollinating
  • Pecan – 200 to 1600 chill hours – Zones 5 – 9 – most require cross-pollination
  • Persimmon – 100 to 500 chill hours – Zones 5 – 9 – some are self-pollinating
  • Pomegranate – 100 to 200 chill hours – Zones 7 – 10 – self-pollinating
