N: Urea the largest agricultural nitrogen fertilizer such as Ammonium and Ammonium Nitrate are fine. P: mono-ammonium phosphate, di-ammonium phosphate and ammonium phosphate. At high concentration, it may temporarily reduce water holding capacity. But it can be recovered rather quickly. Try to avoid fertilizers or additives containing metal irons other than Group I Alkali Metals such as Aluminum, Iron, Calcium, Magnesium, which are common in many mixed type fertilizers.
I used hydrogels before for my trees, it did not show any difference. Since you use hydrogels for watering holding and slow release purposes, how is it different?
Conventionally, hydrogels are used by mixing in soil. For surface irrigation methods and natural precipitation, water must penetrate to a certain depth of soil before it reaches the hydrogel particles, which means it does not reduce runoff. Hydrogels in soil only increases soil moisture content when there is enough watering, which defeats the purpose of using hydrogels. Hydrogels in soil do not reduce evaporation, do not eliminate competition, and sometimes it competes with plant for moisture, like desiccants.
It does not compete with root for moisture. Instead, it releases water into soil and then plant roots get it from soil. My city uses watering bags for our city trees, but we do not have enough labor to fulfill the required refilling of those bags.
Can we solely rely on rainwater and not water them? JavaScript seems to be disabled in your browser. For the best experience on our site, be sure to turn on Javascript in your browser. This tree staple root anchor acts like an artificial root system.
This holds your tree roots in place instead of calbes, stakes, above ground anchors, etc. These are underground and out of the way. This unique tree stabilization system uses all below ground anchoring. With no wires, above ground anchors or stakes to look at and mow around.
The tree staple is installed when you are planting the tree by driving them into the root ball and into the ground underneath.
Newly planted trees are most susceptible to winter drought injury. Trees generally take one year to establish for each inch of trunk diameter. For example, a two inch diameter caliper tree takes a minimum of two years to establish under normal conditions. Trees obtain water best when it is allowed to soak into the soil slowly to a depth of 12 inches.
Methods of watering trees include: sprinklers, deep-root fork or needle, soaker hose or soft spray wand. Apply water to many locations under the dripline and beyond if possible. If using a deep-root fork or needle, insert no deeper than 8 inches into the soil.
As a general survival rule, apply 10 gallons of water for each diameter inch of the tree. For example, a two-inch diameter tree needs 20 gallons per watering. Newly planted shrubs require more water than established shrubs that have been planted for at least one year. The following recommendations assume shrubs are mulched to retain moisture. In dry winters, all shrubs benefit from winter watering from October through March.
Apply 5 gallons two times per month for a newly planted shrub. Small established shrubs less than 3 feet tall should receive 5 gallons monthly. Large established shrubs more than 6 feet require 18 gallons on a monthly basis. Decrease amounts to account for precipitation. Water within the dripline of the shrub and around the base.
Herbaceous perennial establishment periods vary. Bare root plants require longer to establish than container plants. Perennials transplanted late in the fall will not establish as quickly as those planted in spring.
Winter watering is advisable with late planted perennials, bare root plants, and perennials located in windy or southwest exposures.
