How to Protect Your Plants from Heavy Rains
The storms do not spare anyone or anything, not even our gardens. To minimize if not completely prevent damage, you must take some measures to secure your plants. Here are some tips on how to protect your plants from heavy rains.
- Check the drainage system or canals for clogging. Remove anything that will cause flooding. Also check the drainage holes of your pots to prevent stagnant water in the plant roots.
- Transfer potted plants that cannot stand too much wetness or strong winds to a dry and covered area with good ventilation for safety.
- Apply fungicide before and after a long period of rain. Withhold watering if you know that heavy rains are coming.
- Prone heavily the crown of big trees and remove heavy branches. Top-heavy trees can easily be toppled down by strong winds.
- Cut down tree branches that may fall on electric wires, roofs, green house or plant beds and benches.
- Paint your metal benches, wrought iron chairs, tables, fences, and steel posts with a good rust-proofing agent.
- Incline your plastic sheet roofing over your plants to prevent water to gather and accumulate. The weight of the accumulated water may break or tear it.
- Remove plastic roofing or netting on your green house temporarily to avoid being blown or torn by strong winds.
- Trees may be struck and burned by lightning. Set up a metal pole taller than the trees but away from them and stick it deep into the ground. The metal pole will attract the lightning bolt and conduct it to the ground instead of hitting the trees.
- Anchor big trees to the ground by tying their trunks on four sides with strong G.I. wire. Tie the ends of the wire on strong wooden pegs stuck to the ground. Put heavy boulders on top of these pees. This way, the trees can resist or withstand the blow of stormy winds. You can further secure the anchorage by surrounding the base of trees with heavy boulders.
- If you previously applied much around the plants during the hot summer months, you have to remove these now to prevent excess water from accumulating around the plants.
- Remove infected or diseased plant parts before the rains set in. These infected parts may spread the disease further to the healthy parts of your plants.
- Put up windbreakers such as fishnets and cyclone wires along the side of your garden where strong wind comes in.
- A little before and right after the rain, thrips, slugs and snails as well as host of other pests and parasites will infest your garden. Spray your plants with a water based insecticide or other type of pesticide suited for each type of pests. Try to use the environment-friendly brands.
- Treat wounded parts of trees with a sealing fungicide to prevent infection spreading into the inner parts.
- It is alright to allow weeds and grasses to grow before and during the rainy season to absorb excess water in the ground. But insects and other pests thrive there, so remove these grasses soon after the rain.
- Do not burn dead leaves, grasses and fallen branches, shred or chop them finely and bury in compose pits. They can become organic fertilizers.
- Save as much rainwater as you can, in big containers. You can use it to water your plants during summer days.
- Plants like heliconias, birds of paradise, cannas, flowering gingers, curcuma, and ornamental bananas love to be flooded.
- Liliums, agaves, palms and pines can withstand moderate to steady rain.
- Ti plant, gumamela, santan, dracaena, and duranta are sturdy enough to be left out in the rain.
- Ground covers like yellow peanut, cucharitas and grasses will prevent soil erosion.
- Annuals like vincas, petunias, mums, gloxinias are very delicate and need a regulated watering.
- Sansivieria, aloe vera and most succulents will rot in too much water.
