DESIGN ELEMENTSWhy Trees Fail/Fall?
When a large, mature falls in your garden, it can be very disheartening, especially if it’s a special or favourite tree.

Sometimes it’s obvious why a tree may fall in your garden, but what are the underlying factors?
I'm talking with Glenice Buck, consulting arborist and landscape designer.
Let’s find out .
There are many reasons why trees fail or fall.
- Trees need to be growing in well drained soil.
- If the soil holds onto too much moisture, this results in no oxygen in the soil, leading to tree roots rotting, making the tree unstable.
- Trees not planted correctly is another factor.
- The planting hole needs to be wide enough so there there is enough room for the roots to spread . The hole should have more of vase shape, and loosen the soil so there is no soil 'glazing.'
- Don't plant the tree too low in the ground.
- If the tree is planted into a tight narrow space, not giving it enough room for the roots to develop to support the canopy.

- Fun Fact: Did you know that at first, it wasn’t meant for consumption, but instead, celery was used for medicinal purposes, as a flavouring herb, and sometimes fed to horses.
- Celery or Apium graveolens is in the same family as carrots; Apiaceae

- Have you tried growing Celery and found it to be too much work?
- Did you know there are, self-blanching varieties that don't need earthing up to produce tender white stems?
- Celery prefers moisture, well-drained soil in a sunny spot.
- A short row can be squeezed into a garden, raised bed or you could even try dotting the odd plant into a border. If you have a tiny garden it's possible to grow celery in very deep, long tomato style pots.
- Celery prefers warm days and cool nights and grows best in a clay to sandy soil with plenty of moisture.
- If you have time, plants can be started off by sowing seeds. The seeds take 1-2 weeks to germinate.
- Celery seed is tiny, so take a pinch and lightly sow across the surface of the soil. Watering from the top is likely to disturb the seed, so fill a bowl with water and put in the pot. It can be removed once the water has been drawn to the surface.
- Finish by covering with a thin layer of vermiculite and putting in a heated propagator on a windowsill or in a greenhouse. Water daily to ensure the compost doesn't dry out.
- Take the seedlings out of the propagator when they've germinated.
- They're ready to be given pots of their own when the first proper leaves have formed. That means at least 4 leaves.
- Plants will be ready to go outside about five weeks later, when they're 8cm tall.
- One of the main advantages of growing your own is that you can individually pick the stems one by one rather than taking out the whole bunch.
