Water Conservation

Watering in a Heatwave

In this period of high heat, it makes sense to water more often than usual. We water twice as much in July as we do in other months. BUT REMEMBER that plant roots need air, too. And if the soil is continually wet, plant roots won’t be able to use the water, and may rot. The best approach is still to water deeply, but not too frequently. The best time to water is in the early morning when less water will evaporate, and water droplets can dry from plant leaves early in the day, certainly before evening when fungal diseases can take hold on wet foliage. What does that mean, “water deeply”? It means that when you irrigate by hand or sprinkler or drip, the soil should be moist to a depth of at least 4”.  Moisture meters and the old ‘screwdriver test’ are not as accurate as digging a small hole 4 to 6” deep and feeling the soil. If it is dry at 4” just after watering, you will need to water longer. [Read More]

Bagged Composts

These are the composts we carry during the season, although we don’t always have them all in stock at the same time:[Read More]

Bagged Mulches

Fine Woodchip Mulch: Mats tight to prevent blowing by the wind, and lets less light get to weed seeds, has more nutritive potential than cedar or redwood, decomposes rapidly against the ground.

 

 

 

Soil Pep: Partially composted fine bark mulch, dark and beautiful, ideal for rose gardens, shrubs and perennials, premium quality for front entrances and high visibility.

Big Foot Mycorrhizae

The Soil Food Web is an important component for healthy plants. This concentrate has not only outstanding Mycorrhizae but also carriers of Biochar, kelp and worm castings. Improve water and nutrienet uptake, root growth and plant growth while reducing transplant shock and drought stress.

Hydrosource

This is a water-absorbing gel that absorbs 200-400 times its density in water. It is used as a soil amendment to increase the water-holding capacity of soils, reducing watering frequency by 20-40% in the ground and 50-75% in containers and hanging baskets. It greatly aids establishing of young plants, and improves soil structure, staying effective for 8 years. It has been used to help trees in drought and to reduce the water requirements of lawns. I have used this product for 12 years in producing plants from seed and found it very useful, needing very little in the soil. It is a synthetic polyacrylamide polymer that has been determined nonhazardous by OSHA, but has not passed organic standards by OMRI.

Myke Mycorrhizae

Myke has two different blends of mycorrhizae to help when transplanting. One for vegetable gardens in the green bag and one for tress and shrubs in the blue box. Both stimulate root development and phosphorous uptake while reducing watering needs.
