GIBMP? What’s That?
- Be sure to remove the coverings over your plants as soon as the temps are above freezing, especially if they are in the sun.
- Resist the urge to remove freeze-damaged portions of plants for now. If we have another freeze, the damaged portions will shelter any tender new growth down below.
- Your warm season grass is either dormant, or going dormant this time of year. This means its roots become much shorter, and it needs no irrigation. Do not apply nitrogen to dormant turf grass. Over time (several years), applying nitrogen to warm-season grass during winter will damage your lawn. Excessive nitrogen attracts and feeds chinch bugs. More on that later. For now, please just trust me.
- Some folks like to over-seed dormant grass with winter rye grass. Please don’t do this. Dormant grass does not need water, but winter rye does — this will damage your dormant grass. The rye seeds also get into your neighbors’ yards through wind and bird droppings.
- In the event of another hard freeze, do not use plastic bags or tarps to cover your tropical or tender plants — everywhere the plastic touches the plant there will be freeze damage. Overturned plastic pots that plants come in can be used to cover small plants because they don’t actually touch the plant. Placing a rock or brick on them will (a) keep the pot from blowing off in strong wind, and (b) cover the drainage hole, thus keeping out cold air.
I’ve been working on a blog post about which of my flowers and foliage plants survived our recent nights of freezing temps. It’s not quite done yet, but it will show photos of those that survived. Another post will show those that did not do well. Hint: the flowers that did best were the snapdragons.
