To water Thick leaved lavender, you can use a garden hose with a spray nozzle, a watering can, or just about any other common watering tool. Generally, Thick leaved lavender is not too picky about how they receive their water, as they can live off of rainwater, tap water, or filtered water. Often, you should try not to water this plant from overhead, as doing so can damage the leaves and flowers and may lead to disease as well. At times, the best method for watering this plant is to set up a drip irrigation system. These systems work well for Thick leaved lavender as they apply water evenly and directly to the soil. For one Thick leaved lavender that grows in a container, you can use a similar watering approach while changing the tools you use. To water a container-grown Thick leaved lavender, use a cup, watering can, or your tap to apply water directly to the soil.

The remedy for underwatering Thick leaved lavender is somewhat obvious. When you notice that your plant lacks moisture, simply begin watering it on a more regular basis. The issue of overwatering can be a much more dire situation, especially if you fail to notice it early. When your Thick leaved lavender is overwatered, it may contract diseases that lead to its decline and death. The best way to prevent this outcome is to choose a proper growing location, one that receives plenty of sunlight to help dry the soil and has good enough drainage to allow excess water to drain rather than pooling and causing waterlogged soils. If you overwater your Thick leaved lavender that lives in a pot, you may need to consider changing it to a new pot. Your previous container may not have contained soil with good drainage or may not have had sufficient drainage holes. As you repot your overwatered Thick leaved lavender, make sure to add loose soils and to use a pot that drains efficiently.

Thick leaved lavender needs water regularly throughout the growing season. Beginning in spring, you should plan to water this plant about once per week. As the season presses on and grows warmer, you may need to increase your watering rate to about two to three times per week. Exceeding at this rate can be detrimental to your Thick leaved lavender. With that said, you should also ensure that the soil in which your Thick leaved lavender grows remains relatively moist but not wet, regardless of how often you must water to make that the case. Watering Thick leaved lavender that lives in a pot is a bit different. Generally, you'll need to increase your watering frequency, as the soil in a pot can heat up and dry out a bit faster than ground soil. As such, you should plan to water a container-grown Thick leaved lavender a few times per week in most cases, versus just once per week for an in-ground plant.

There are a few different ways you can go about determining how much water to give to your Thick leaved lavender. Some gardeners choose to pick their water volume based on feeling the soil for moisture. That method suggests that you should water until you feel that the first six inches of soil have become moist. Alternatively, you can use a set measurement to determine how much to water your Thick leaved lavender. Typically, you should give your Thick leaved lavender about two gallons of water per week, depending on how hot it is and how quickly the soil becomes dry. However, following strict guidelines like that can lead to overwatering if your plant requires less than two gallons per week for whatever reason. When growing Thick leaved lavender in a container, you will need to use a different method to determine how much water to supply. Typically, you should give enough water to moisten all of the layers of soil that have become dry. To test if that is the case, you can simply stick your finger in the soil to feel for moisture. You can also water the soil until you notice a slight trickle of excess water exiting the drainage holes of your pot.

It can be somewhat difficult to avoid overwatering your Thick leaved lavender. On the one hand, these plants have relatively deep roots that require you to moisten the soil weekly. On the other hand, Thick leaved lavender are plants that are incredibly susceptible to root rot. Along with root rot, your Thick leaved lavender may also experience browning as a result of overwatering. Underwatering is far less likely for your Thick leaved lavender as these plants can survive for a while in the absence of supplemental watering. However, if you go too long without giving this plant water, it will likely begin to wilt. You may also notice dry leaves.

You can expect your Thick leaved lavender’s water needs to increase as the season moves on. During spring, you should water about once per week. Then, as the summer heat arrives, you will likely need to give a bit more water to your Thick leaved lavender, at times increasing to about three times per week. This is especially true of Thick leaved lavender that grow in containers, as the soil in a container is far more likely to dry out faster than ground soil when the weather is warm. In autumn, while your Thick leaved lavender is still in bloom, it may need a bit less water as the temperature has likely declined, and the sun is no longer as strong as it was in summer.

Thick leaved lavender will move through several different growth stages throughout the year, some of which may require more water than others. For example, you will probably start your Thick leaved lavender as a seed. While the seed germinates, you should plant to give more water than your Thick leaved lavender will need later in life, watering often enough to maintain consistent soil moisture. After a few weeks, your Thick leaved lavender will grow above the soil and may need slightly less water than at the seedling phase. Then, once this plant is mature, you can begin to use the regular watering frequency of about once per week. As flower development takes place, you may need to give slightly more water to aid the process.

There are several reasons why most Thick leaved lavender grow outdoors rather than indoors. The first is that these plants typically grow to tall. The second reason is that Thick leaved lavender needs more daily sunlight than most indoor growing locations can provide. If you are able to provide a suitable indoor growing location, you may find that you need to give your Thick leaved lavender water a bit more often than you would in an outdoor growing location. Part of the reason for this is that indoor growing locations tend to be a lot drier than outdoor ones due to HVAC units. The other reason for this is that soil in containers can dry out relatively quickly as well compared to soil in the ground.

Thick leaved lavender is a kind of annual plant so it doesn't need much pruning. You only need to cut off and clean the diseased, yellow or dropped leaves and stems during its growing period. This will help your Thick leaved lavender to stay away from pathogens infection.

During the growth of the plant, yellowing, drying and spotted leaves are produced, and these spotted and discolored leaves need to be trimmed off. If the whole piece of leave is discolored or infected, you will need to cut it off completely. In other situations, you will only need to cut off the discolored or infected part on certain leaves. Thick leaved lavender above the ground will die and dry up in the winter, and the dead plants need to be cleaned up.

Thick leaved lavender leaves are delicate, so take care not to score or bruise them. Unless the leaves are withered or heavily discolored, do not prune the leaves from the lowermost branches unless they’re damaged. They typically grow the largest, so they supply the plant with critical energy to keep it growing right. Please prevent the wounds from water after pruning until they are fully recovered. Remember always sterilize the tools before pruning. When the pruning is finished, please throw all the waste leaves and stems into the trashbins to avoid diseases and bugs.

Expect to prune your Thick leaved lavender every week if it’s growing well or every two weeks if it grows slowly. It is always good to prune it on sunny days because if you prune it on rainy days, the rainwater will distain the cuts and cause the whole plant to be infected.

Because Thick leaved lavender is an annual plant, the pruning should take place basically during the seasons that the plant grows rapidly. During the growth of the plant, yellowing, drying and spotted leaves are produced, and these spotted and discolored leaves need to be trimmed off.

All plants need nutrients to grow, but some types are able to take what they need and don’t need any supplementation with fertilizers. Thick leaved lavender, like other plants, use nutrients to support growth and all internal processes.

Each of the main nutrients that plants use (nitrogen, phosphorus, and potassium) contribute to one or more of a plant’s essential functions, and in the case of foliage it is nitrogen that provides the most support. It can be difficult for a Thick leaved lavender to get enough nitrogen from the soil, which is why many gardeners prefer to supplement by feeding Thick leaved lavender with a source of nitrogen.

Thick leaved lavender generally grows well, but a fertilizer can be applied about once a month to give the plant a boost when it is actively growing. You should fertilize Thick leaved lavender about once a month only during the spring and summer months, but not during fall and winter when it becomes less active and does not use as many nutrients.

You’ll know when to start fertilizing Thick leaved lavender if you see signs of new growth. The fertilization schedule remains the same whether the plant is grown outside or indoors in a container. However, if your Thick leaved lavender is in a container, you probably will not need to fertilize for the first one to two months. Potting soil made for container plants already contains plenty of nutrients, so you should only start to fertilize after your plant has been in the same soil for a while.

Never fertilize your Thick leaved lavender if it is not healthy, for example if it has developed a disease or has insect pests on it. Also do not fertilize a dehydrated plant, since the fertilizer will make this problem even worse. Only fertilize healthy plants.

Do not splash fertilizer onto the leaves or stem of this plant when watering, since it can cause burned spots. Be careful not to allow the fertilizer to make direct contact with the plant, unless you are usually a special fertilizer designed to be applied to the foliage.

Fertilizers contain high levels of nitrogen, potassium and phosphorus, along with other essential nutrients such as iron, manganese and zinc. These are all necessary elements that promote growth in Thick leaved lavender.

A balanced fertilizer works well for Thick leaved lavender, for example an all-purpose fertilizer with a 10-10-10 NPK number. For natural fertilizers, blood meal or worm castings work well. You may also choose a fertilizer that is higher in nitrogen than other nutrients, such as fish fertilizer. Nitrogen provides support to leaves, which are the main feature that people want from Thick leaved lavender. There is no point in providing a lot of supplements for flowers or seeds if that is not your purpose in growing the plant.

Apply fertilizer based on the instructions on the particular type you have purchased. It is generally a good idea to start with half-strength fertilizer to avoid accidentally over-fertilizing your Thick leaved lavender. Since this plant requires frequent fertilization, it is common to accidentally fertilize too much. Remember that it’s always easier to add more fertilizer than it is to try to save an over-fertilized plant.

Don’t apply fertilizer to dry soil - it should already be at least somewhat moist before fertilizing. This helps the fertilizer absorb more easily and helps avoid fertilizer burn. You should also water after applying dry fertilizers to your soil.

Some fertilizers are meant to be mixed into the soil when planting, while others are applied on top of the soil and then watered in. For most types of Thick leaved lavender, a water soluble fertilizer is an easy choice. Simply mix the fertilizer solution into your watering can at the recommended dosage for Thick leaved lavender and then water the plant as usual. Slow-release granules or fertilizer spikes can also work well if you prefer not to remember to fertilize monthly.

Over-fertilization leads to a build-up of salts in the soil which leads to a lack of vitality overall and pale coloration in the leaves. Leaves may also wilt or develop brown tips as the excess salt from the fertilizer tries to make its way out of the leaves.

Too much fertilizer makes it impossible for the plant to take up water and nutrients, which will eventually kill it if you don’t take steps to save your Thick leaved lavender. If the Thick leaved lavender is in a container, you could either remove it from the pot and repot it in fresh potting mix, or flush out the soil by running a lot of water through and letting it drain out thoroughly.

If your Thick leaved lavender is outdoors, the same theory applies, although it can be more difficult to flush outdoor soil. Water thoroughly and hold off on fertilizing again for a while. You may want to perform a soil test before you add any more fertilizer to make sure you don’t provide too much of any one nutrient.
