How to water the borage plant
Borage is a very strong plant but like many others it suffers from stagnant water. It does not need to be wet abundantly and every day but prefers occasional watering; to know the best time to proceed with a new irrigation it is sufficient to test the soil. Gently placing a finger on it, you notice the level of soil moisture. If the fingertip has no traces of water and wet soil then it is possible to water. For borage the rule is "one less watering less than one more". To avoid stagnation of water it is good to choose a type of soil that is not too thin and compact or possibly mix it with other substrates of different grain size by arranging the coarser fragments on the bottom of the vase.
How to take care of borage
Borage loves direct sunlight. For this reason it is good to choose the brightest possible position, thus guaranteeing a sufficiently warm temperature. The soil must be well drained and although it is a very strong plant capable of taking root even in the universal soil, the best is the slightly calcareous one mixed with sand or expanded clay. It is necessary to guarantee borage the best possible exchange of air without exposing it to sudden changes in temperature that occur when the vessel is placed close to the opening of a window. The development of borage in pots is very fast but does not like transplants much: to make it grow healthy and strong it is good to gradually increase the diameter of the pot .
When and how to fertilize borage
Borage does not usually need fertilizing. It is in fact a robust plant which hardly suffers from deficiencies of essential nutrients. It does not need to be fertilized during the flowering period but it can be supplied with a support by mixing the soil with organic fertilizer. In the absence of organic fertilizer or the possibility of creating compost in the home, it is possible to opt to add common vegetable peels to the earth, gently burying them a few centimeters to bring them closer to the roots. By wetting the plant, the substances whose skins are rich will be made available and assimilable to the extent that the plant needs.
Borage: borage diseases and possible remedies
Borage is not easily affected by diseases. The greatest danger derives from stagnant water that can create such high humidity that the roots rot and in this case you can appreciate the variation in the color of the foliage which tends to turn yellow and easily detach from the stems.It can be attacked by some parasites that fall into the category of leaf miners among which the most common and easily recognizable is the Longitarsus jhosipi. Also snails and slugs can attack the borage deeply affecting the structure and although it is rare, in this case it is possible to eradicate the parasites using special products. Snails can also be removed manually when, in conditions of high humidity, they expose themselves to sight.
