For application by sprayer or watering can:

  • Yucca is a natural liquid plant wetting agent for hard to wet soils
  • Improves rain and water penetration in to dry soils
  • Increases water retention in otherwise dry or problem soils
  • Beneficial to grass; improves root growth and depth
  • Increases biological activity in soils
  • Used on professional sports turf world wide
  • Easily applied by watering can with sprinkle bar or by sprayer
  • To be repeated every 4 weeks until desired result is achieved

As a Preventative for Recurring Conditions, Fairy Rings & Dry Patch

  • Start treatment around May time prior to soil drying
  • Spike problem area with garden fork, aerator sandals or rolling aerator
  • Apply recommended dose of YUCCA wetting agent
  • Water after 7-10 days if no or little rain
  • Repeat above routine every 4 weeks to maintain grass growth and water penetration
  • Seed and fertilise area after first application if no grass present
  • Maintain a good fertiliser programme and mow regularly on medium to high

For Treatment of Existing Problems

For dry patchy summer lawns, under trees or prior to seeding dry areas; start treatment at the first signs of dryness and poor grass recovery or 2-3 weeks prior to seeding. Treat as above until grass recovers with as much additional spiking as possible. Spike depth will be shallow initially as the ground will be hard. As water starts penetrating you should be able to spike deeper.

How much do I need?

Plan on at least 3 applications to a problem area. Long term conditions in older lawns may need treating every month from April to August (5 applications). This means typically you would need to order enough to treat the total area 3 to 5 times in any one year. This product has a shelf life of 3 years.

Other uses

  • Anywhere that there is a dry soil problem, perhaps after removing large fibrous plants, shrubs, bushes or trees
  • Around dead tree stumps
  • Around ants nests - useful prior to applying poisons that need to penetrate the soil
  • To re-wet hanging baskets and tubs
  • Also reduces run-off in hanging baskets and tubs by improving permeability

Either use at the recommended rate for dry patch and fairy rings or if treating hanging baskets water as normal but put 20ml Yucca Wetta in 10 litres water once. Repeat after 4 weeks if needed.

Chris Stuart
Bought Yucca Wetta wetting agent after seeing some positive comments online, and I am VERY impressed with the results. I had a couple of very dry patches on my lawn, and they're now pretty much fixed after just three applications over the period of a few weeks. I would thoroughly recommend the product,
