help with watering newly planted garden beds

7 years ago

Hello,

I'm sorry for the long post that follows but I thought it was important to be specific. I'm wondering if you smart, green-thumbed individuals out there could help me figure out when and how much to water my newly planted garden beds. I have 2 medium sized beds that were planted by a local landscaper. We have some boxwoods, incrediball hydrangeas, summer alliums, avalanche and karl forester ornamental grasses, zegrab, d'oro daylillies and a veronica ground cover. I live in Wisconsin, only a block or 2 from Lake Michigan, so my summers are usually pretty moderate but this year has been unusually hot (for everyone in the country I think). Lastly, we have clay soil and the landscaper did put down a layer of compost before planting followed by a layer of hemlock mulch.

I have tried to read up on watering but I keep reading conflicting information. I know new plants need to be watered frequently. But then I have read in several places the importance of letting the soil dry out before watering again. Our clay soil holds onto moisture so it rarely feels totally dry to me. I have been checking the soil with my hands to feel if it is dry, but then I end up watering every 3-4 days anyway because I get too nervous to wait longer. Are you supposed to let the soil dry out for newly planted plants or is that just the rule for an established garden? And if there are different rules for newly planted vs established, when does the "newly planted phase" end? I'm having trouble determining when it is time to water because my soil does not dry out every 2-3 days but I thought that is how often I am supposed to water.

I have read the best way to water is slowly and deeply at the base of the plant. It is not practical for us to lay a hose at the base of the plants and move it around the base and from plant to plant (the ideal method from what I have read) because we had about 75 plants planted. We would be standing there moving the hose every few minutes all day. Are soaker hoses adequate? I have been trying those and I feel it is providing the slow trickle we are looking for, but still we are only getting one side of a plant in most cases, unless we reroute all of the hoses half way though. This brings me to my next problem - watering in the morning. With 2 toddlers and 2 full time working parents, we don't have hours to be tinkering around with hoses in the morning. If we can connect the soaker hose and leave it for thirty minutes or an hour and shut it off, that is doable. If we need to be moving it around to get the total circumference covered, we probably don't have time for this in the morning. Can we water in the evening? I have read that morning watering is best and evening watering can cause rot and other issues. But its a trade off- in the morning the best we can do is turn on a soaker and leave it, vs in the evening I could find a little more time to move a hose around to fully get the bases of the plants. Which would be preferable?

I VERY much appreciate some advice. Oh and I should say that my husband put the kabosh on installing a drip irrigation system. Thank you!

Assuming that the bed was moist when planted, early irrigation for the plants will be as you are doing -- frequently and a modest amount.

After the plants are established, you can move to less frequent but deep.

"Deep" in any case, is the depth of the entire root system.

The time to water is when you have the time. Along with that, a critical goal is to have the plants fully hydrated when they meet the day.

The key to avoid leaf diseases, is to water at ground level -- that is, keep the leaves dry.

If watering overhead, do so early enough in the day that the leaves dry before nightfall.

Lay out the soaker and leave it in place. (Re-arranging it daily is a nightmare.) Even so, I find that hand watering each small rootball is important to help the transplants get through the 1st 10 to 14 days.

Enjoy your garden!

Yes, they might have gotten dried out or they might have been burned by the fertilizer - if too much fertilizer was used, or something else about the application was not right. In addition to being burned directly by mineral salts in the fertilizer recently planted stock that has been given too much fertilizer can also burn during hot weather due to the high amount of fertilizer causing it to produce excessively lush and soft foliage that the plant's roots cannot keep adequately hydrated during high temperatures. In arid or semiarid areas non-adapted kinds of plants can also be damaged by mineral salts in irrigation water. >wrong, wrong, wrongAnd much nursery stock purchased from retailers after it has been in their possession for awhile is nutrient deficient at time of purchase by the consumer.

scotjute: Sorry to take so long to get back but I was waiting for an email notification. The TGG has been in the ground for 3 weeks and seems to be holding it's own. It was trucked in from Oklahoma and took 4 days by UPS. It has a 3/4 inch trunk but there are 2 other 1/4 inch stems coming up from the root ball. Using the soaker hose it gets 18 gallons (2 hours) about every 3-4 days. The temp now runs about 98-104F and the last meaningful rain is a distant memory. (6-8 weeks.) We get most of our rain in July and August during the Monsoon season. About 1/3 of the leaf tips have a yellow tinge to them but like motownnj above I don't know if it's stress or something else. In your opinion, am I giving it too much water? I only soak it when the cheapo moisture meter, my finger and the wooden dowel think it's time. There is 3 inches of Composted Mulch on top which in this climate dries out quickly!

Winter watering schedule for newly planted japanese maples?
Q

How often or even if you need to water at all will depend on your weather. Here in the moist PNW, once fall hits and the leaves begin to drop, I never need to water anything outdoors.......and that includes all my containerized maples as well. We get as much natural irrigation as necessary from Ma Nature :-) However, if you live somewhere where it tends to be quite dry in winter, yes, you will need to water periodically. Typically since temperatures are lower in winter, soils do not dry out as rapidly as they do during the growing season. And trees in dormancy do not need the same degree of hydration as they are not going through any transpiration. But you do not want the soil (and therefore the root system) to dry completely. Check the soil periodically as may be determined by weather conditions. If very dry to the touch down to the second knuckle, then provide water. I can't think of many places in your zone where you would need to do this more than a two or three times during the winter months. The soil should be just moist to the touch.

How much water would newly planted helebores need??

Hellebores are drought tolerant evergreen perennials once established in zones 4-8. They prefer rich, moist (not wet), well drained soil. In general, watering slowly (hose on a trickle), deeply (for about 15-30 minutes for a 1c size container grown plant) and less often develops strong, drought tolerant root systems (that goes for all plants). The amount of water a plant needs depends on soil type, rainfall, wind and temperatures. In general, water new plants every 3-5 days for the first 4-6 weeks, then maybe once a week through out the growing season. If you live in an area that receives high summer temperatures, you may need to water more often throughout the summer months. If you receive a slow steady soaking rain without a lot of wind, you might be able to wait 5-7 days between watering. You can purchase soil moisture meters at garden centers or use your finger to check how moist/dry the soil feels around the roots, approx. 4" below the surface. Leaf compost or finished compost from your compost pile makes great mulch around Hellebores. Depending on your soil type (always helpful to do a soil test, check with your local county extension office or local garden center), a slow release organic fertilizer can be applied in spring. You can also cut the brown leaves off the plants in late winter being careful not to cut the flower buds that are forming for the current year's blooms. Hope this helps and Happy Gardening!
