What time to plant

Growing Incarvilla in your garden plot is quite easy. Such a crop is grown through seedlings.

The seeds are sown in March. It should be taken into account that the seeds of such a plant have a relatively high germination rate. In the soil mixture to deepen the seeds to 10 mm, then top them covered with a layer of preheated and had time to cool river sand. The seeds should be watered and taken to a warm place (18 to 20 degrees). The first seedlings should appear after about 7 days.

Picking such plants is extremely undesirable, as they are very difficult to tolerate this procedure. It is therefore recommended to use peat pots for sowing seeds and growing seedlings. Planting seedlings in open soil is made in the last days of April, and planted directly in these pots. If the seedlings are grown in a common container, after the plants will start to form the first pair of true leaves, then they need to unpack in individual cups. If you're going to grow Incarvilla perennial or biennial, then seed can be sown directly in the open soil, and you can do this in April-July.

The optimum temperature for the emergence of seedlings about 15 degrees, in which case they will show up in about 15 days. But you should remember that a plant grown in this way will not start blooming until the following year.

Planting rules

For growing this flower, it is recommended to choose a site on an elevated position (slopes or hills), since it reacts extremely negatively to stagnant liquid in the root system. If the planting is made in too dense soil, the experts recommend, when creating a flower bed be sure to make a good drainage layer, you can use coarse sand, broken bricks or gravel. For Incarvillia, you can choose a well-lit and open area, but it should be taken into account that in the afternoon the bushes must be necessarily shaded.

Suitable soil should always be nutritious and light, for example, sandy loam. In the planting holes during the planting of seedlings, it is recommended to pour a handful of ash and fertilizer of prolonged action. The seedlings are pulled out of the cups very carefully, because the root system is very fragile, and it can easily be traumatized. Landing plants in the open ground, you should remember that its root neck should be slightly sunk into the soil. The soil around the plant should be well compacted and then watered generously.

How to water and fertilize

Care for Incarvilla is very easy. It needs to be systematically watered, weeded and loosen the soil surface around the bushes. Water in moderation and remember the following rule: do not let the soil get too dry and do not let it accumulate too much water in the roots. When it rains or the plants are watered, the surface of the ground around the shrub should be gently loosened, simultaneously pulling out all the weeds.

The first feeding should be done with a complex mineral fertilizer after the flower has started to actively grow greenery.

The second feeding should be carried out during the formation of buds. Also such a culture can be fed with a solution of poultry manure or cow dung. From 20 July, stop all feeding. Annuals do not need nutrition at this time, while perennials do harm because they reduce their resistance to frost.

How to propagate and replant

Incarvilla can be propagated by generative (seed) and vegetative methods: by leaf cuttings and division of tubers.

How to grow this flower from seed is described above.

The propagation procedure by dividing the tubers can be done in March or September. After the bush has been taken out of the ground, it is cut into several parts, taking into account that on each partition there must be a point of renewal and at least one tuber. The places of the cuts should be sprinkled with crushed charcoal. Then the parts of the bush are planted in pre-made planting holes, and the point of growth should be deepened in the ground by 40-50 mm.

Raising with leaf cuttings is carried out in summer, more precisely, in June-July. To do this, a mature leaf plate must be cut out of the rosette with a part of the stem 30 to 50 mm in size. The cut should be treated with a solution that stimulates root growth, such as Kornevin. The leaf cuttings are then planted in a soil mixture consisting of peat and sand, and the box is then removed to the greenhouse. At first the cuttings grow roots, then a leaf rosette is formed, and already in the next season you can see the flowering of a young bush.

Hibernation

Incarvilla perennial in time of preparation for winter must be covered, especially it concerns those regions where winters have little snow. The site is covered with a layer of compost, sawdust or peat, instead of that it can be covered with spruce twigs. Note that the thickness of such a layer should be at least 60 mm. In spring the cover must necessarily be removed, otherwise the tubers can soak. Young bushes in preparation for winter, you can cover the top with a plastic bottle with a cut-off neck or a glass jar.

If Incarvilla is grown in regions with frosty winters, then it is recommended to remove the tubers in autumn from the soil, immerse them for some time in Maxim solution, dry them and store them until spring.

Diseases and pests

The most common incarvilla is affected by root system rot. If liquid stagnates in the soil, it can cause rotting to develop. The tubers are severely affected, and it is often impossible to cure the bush. When the first symptoms of wilting appear, all bushes should be sprayed with a solution of a fungicidal drug, for example: Fondazole, Skor, Topaz, etc.

In addition, the number and amount of watering should be reduced, and if this is not done, the bushes may fall ill again.

Mildeworms and spider mites settle on such flowers most often. These pests are suckers. They suck the cell sap from the shrub. You can tell that "uninvited guests" have settled on the plant by deformed and withered leaf plates, shoots and flowers.

To get rid of the pests, Incarvilla should be treated with an acaricide such as Actara, Actellic etc.
