Helping plants survive a cold snap
Avoid the use of high nitrogenous fertilisers at this time of the year to prevent cold damage. Soft new growth is more affected than hardened off leaves. The addition of a composting mulch will create warmth as it breaks down. It also serves the purpose of an insulated blanket on the soil. Composting mulches are those mulches that break down over time and will feed the soil as they decompose. Remember to leave a gap around the plant’s trunk about 100mm when applying mulch to allow the warmth of the soil radiate from ground level.
If a cold snap is forecast cover your plants, bring sensitive varieties in under cover if possible and apply Seasol or Seasol GOLD to the soil. Seasol or Seasol GOLD with provide improved cold tolerance if applied regularly (every 2 to 4 weeks) throughout the year.
If early frosts are experienced resist the temptation of pruning the damaged growth off too early. Wait until the danger of cold has passed or the plant has started to recover on its own by producing new growth. As much as it’s hard to look at it, the damaged leaves will be protecting the new growth as it emerges.
